Summary

  • BM-Bank is best understood as a live, VTB-controlled banking perimeter rather than a dormant shell or a standalone growth bank: it holds a universal banking licence, securities-market permissions, deposit insurance status, high capital ratios, sanctions exposure and active network resources, while much of the attractive customer business has been moved or is being moved toward VTB.
  • The bank's technology and routing footprint is economically useful only if it supports regulated continuity: former Otkritie accounts, residual deposits, unusual loans, securities servicing, sanctions-aware communications, data locality and controlled migration. It does not look like an independent network-services business, and public evidence does not show a mass-market BM-Bank customer franchise being rebuilt under its own name.
  • The decisive change-of-view fact is the 2025 reversal in integration expectations. Early public commentary treated BM-Bank's merger into VTB by 2026 as the natural end state, but later reporting tied to former Otkritie subordinated creditors made the unchanged merger plan legally hazardous. That makes the retained BM-Bank boundary look less like inertia and more like a deliberate container for obligations that VTB does not want to absorb directly.

The most useful way to begin BM-Bank is not with its historical brand or its autonomous-system numbers. It is with a customer who once used Otkritie or one of Otkritie's predecessors and later discovered that the economic owner of the relationship, the legal counterparty and the servicing bank were no longer the same intuitive thing. A retail borrower with an auto loan may be told that rights are being transferred to VTB, that the loan's core terms do not change, that a new loan agreement is not required and that payment should now run through VTB channels.

A military mortgage borrower may see a similar destination: former Otkritie obligations reorganized through BM-Bank, then serviced by VTB. A bondholder or securities client may face a different version of the same problem: the issuer or account-servicing counterparty is now BM-Bank because the predecessor bank ceased to exist, while the economic expectation of support rests on the VTB group. That customer-level mess is the bank's operating reality. BM-Bank is valuable, if it is valuable, because it can hold those relationships without pretending that they are clean new business.

The legal surface is substantial. The Bank of Russia lists BM-Bank as an active universal-license credit institution with registration number 2748, OGRN 1027700159497 and INN 7702000406. It is in the deposit insurance system, has a Moscow registered address and reports charter capital of 66.401953 billion rubles after changes registered in March 2025. The regulator's card lists a general banking licence dated October 2016 and also records securities-market permissions, including brokerage and depository licences granted in 2024 and an existing dealer licence. Those facts rule out the simplest dismissal.

BM-Bank is not merely a name left behind after a merger. It is a bank through which deposits, credit balances, securities duties, bond liabilities, regulatory forms and customer notices can still move. A dormant entity does not need this combination of permissions, capital, supervisory notices and live infrastructure.

Yet the actual economic boundary is narrower than the legal boundary. The bank's history matters because BM-Bank is the successor to Bank of Moscow, one of the largest Russian bank rescues of the 2010s. Public reports from 2011 and IMF material described a bank whose asset-quality problems were severe enough to require an extraordinary support package, including about 295 billion rubles of DIA financing and a large VTB capital contribution. Rating commentary in later years still described BM-Bank as a vehicle for problem and non-core assets.

That origin explains why the current bank should not be valued as if it were a clean mid-sized lender with a growth plan. It inherited a rescue function before it inherited the latest Otkritie and Sarovbusinessbank functions. The institution has repeatedly been used as a place where Russian banking problems are made administratively manageable.

The 2025 reorganization changed the scale of that container. The Bank of Russia's payment-services notice says Bank FK Otkritie joined BM-Bank on January 1, 2025. Public securities-depository and issuer notices show Sarovbusinessbank joining the same legal perimeter. ACRA wrote before the transaction that Otkritie and Sarovbusinessbank were expected to join BM-Bank and that BM-Bank would then be integrated into the supporting entity.

NKR later described the completed merger as a large balance-sheet event, saying consolidated IFRS assets rose about sevenfold in the first half of 2025 and that BM-Bank ranked tenth by assets as of December 1, 2025. The Bank of Russia's regulatory balance sheet confirms a dramatic standalone expansion: assets increased from 534.894 billion rubles at January 1, 2025 to 1.911 trillion rubles at July 1, 2025. That is not a cosmetic change. It is a new perimeter for funding, asset servicing, securities books, customer claims and legal risk.

The same balance-sheet evidence also shows why the growth should not be mistaken for ordinary market success. At January 1, 2025, BM-Bank reported client funds of 277.771 billion rubles, non-bank client funds of 269.040 billion rubles, retail deposits of only 2.717 billion rubles and subordinated funding of 97.915 billion rubles. By July 1, 2025, client funds had climbed to 1.254 trillion rubles, but funds from credit institutions were 904.291 billion rubles, retail deposits were 77.014 billion rubles and subordinated funding remained around 98.179 billion rubles.

Securities were large: 361.279 billion rubles of assets measured through other comprehensive income and 656.117 billion rubles of securities at amortized cost. The bank's income statement tells the same story. In H1 2025, interest income from securities and financial assets was 84.352 billion rubles, far above the 18.742 billion rubles from client loans. This is a treasury, group, securities and inherited-balance institution much more than a broad new-loan retail bank.

Capital is not the weak point in the public numbers. At July 1, 2025, the Bank of Russia form showed own funds of 547.063 billion rubles and capital ratios of 19.45% for N1.1, 20.00% for N1.2 and 27.42% for N1.0. Those ratios were comfortably above minimums, and ratings commentary treated capital as strong. But capital adequacy by itself does not answer the economic question. A container bank can have very high capital because a parent and a resolution process deliberately make it robust enough to hold difficult positions.

The relevant question is whether that capital is being paid to support a profitable live franchise, or whether it is the cost of keeping disputed, sanctioned or hard-to-transfer obligations away from a larger group balance sheet. BM-Bank's public evidence leans toward the second interpretation, with the qualification that a well-run container can still be economically rational.

The cost line is important. BM-Bank reported operating expenses of 4.034 billion rubles for 2024, before the full Otkritie perimeter appears in the mid-year 2025 forms. In H1 2025, operating expenses reached 19.840 billion rubles. That increase is unsurprising after absorbing a larger operating boundary, but it sharpens the central test. A bank with expensive regulatory, staff, IT, sanctions, customer-service and securities obligations cannot justify itself merely by existing.

It has to either earn enough spread and fee income from the retained books, reduce risk for VTB by more than it costs, or provide a legally necessary way to migrate customers without triggering worse losses. The public numbers show net profit of 36.057 billion rubles in H1 2025, so the perimeter was not visibly loss-making in that period. But the income mix, related-party character noted by NKR and large securities exposure make that profit less useful as a measure of independent franchise strength.

Funding is likewise useful but concentrated. NKR identified the DIA as the largest non-credit institution creditor because of the rehabilitation loan and described funding cost as a constraint in tight monetary conditions. The July 2025 regulatory balance sheet showed a large credit-institution funding line and a much smaller retail-deposit base relative to total assets. NKR also said BM-Bank could draw on a parent unsecured loan to cover liquidity gaps. ACRA's rating logic similarly depended on expected support from a highly rated shareholder or supporting bank.

This matters because funding concentration can be economically sensible for a group work-out bank while still limiting stand-alone value. BM-Bank does not need to win millions of low-cost customers if its job is to service residual books and hold securities under group discipline. But the more it relies on the parent, the DIA and related-party economics, the less credible it becomes as an independent bank.

The customer evidence points in the same direction. Public reporting on the Otkritie transaction said the retail loans and deposits that could be transferred to VTB were transferred, while BM-Bank received residual items such as silent deposits and non-standard credit products, including unusual currency mortgages and loans inherited from predecessor banks. VTB's auto-loan notice describes a portfolio-by-portfolio transfer mechanism: rights moved to VTB, customer terms remained unchanged, and borrowers were directed into VTB accounts and digital channels.

Rosvoenipoteka's notice on military mortgages says Otkritie ceased after merger into BM-Bank and that mortgage servicing shifted to VTB. Those are not the moves of a bank rebuilding a consumer franchise. They are the moves of a group trying to separate transferable relationships from awkward or legally sticky relationships, then run the awkward part through a supervised banking shell that remains fully alive.

The word shell, however, can mislead. BM-Bank is not empty. It has customers, assets, obligations, licences, capital, ratings and network resources. The better description is ring-fenced operating bank. It may not be the customer's intended long-term bank, and it may not be where VTB wants its mass-market brand to sit, but it remains the lawful counterparty for claims that cannot simply disappear. The distinction matters for technology. A true empty shell would not need active autonomous systems, Open-linked web resources, securities-market licences or repeated Bank of Russia decisions about organised-trading orders.

A ring-fenced operating bank does need them, because the customers and instruments trapped inside the perimeter still require communications, records, controls and regulated servicing.

The network evidence is unusually revealing. RIPE and RIPEstat records show AS5589, named OPEN-FC-1-AS, as an active autonomous system associated with JSC "BM-Bank". RIPE data for the related organisation record ties the Open network resources to JSC "BM-Bank", and the AS5589 aut-num record shows upstream import and export relationships with Rostelecom and VimpelCom as well as a route set containing Open-related entities. RIPEstat announced-prefix data for AS5589 shows multiple active IPv4 ranges, many with inherited names that point to Open, Nomos, RGSB, BIN and reserve network history.

Separate RIPE records show AS39350, named BMBANK, as an active autonomous system for Joint Stock Company "BM-Bank", with the 195.250.56.0/24 prefix originated by AS39350. IPinfo describes AS5589 as a BM-Bank business ASN with 4,096 IPv4 addresses and no IPv6, and AS39350 as a BM-Bank business ASN with 256 IPv4 addresses and no IPv6.

That footprint should not be over-interpreted. A bank can operate an autonomous system without being a network business. The important fact is not that BM-Bank might sell connectivity; public evidence does not support that. The important fact is that BM-Bank controls or is associated with routed, bank-linked infrastructure that carries inherited digital-banking, brokerage, customer-service, web, reserve and data-security implications. The presence of AS5589 and AS39350 says there is a real technical perimeter to manage. The inherited names say that perimeter is messy and historically layered.

The limited upstream set says concentration is real. The lack of IPv6 in the IPinfo views says modernization is not obvious from the routing surface. None of those facts create a bullish network-services thesis. They create a cost and control thesis: BM-Bank must maintain enough network competence to service regulated financial relationships without letting legacy systems become operational risk.

The technology footprint becomes more economically legible once connected to customer migration. Former Otkritie customers do not all move at the same time or through the same legal mechanism. Some loans can be ceded to VTB. Some deposits may need customer contact or consent. Some securities relationships require issuer and depository continuity. Some loans have unusual currencies or predecessor-bank documentation. Some accounts may be held by customers who do not respond.

A group can push easy relationships into VTB while leaving the rest inside BM-Bank, but the left-behind relationships still need internet access, identity records, statements, notices, payment rails, security monitoring and dispute handling. The cost of the bank's technology footprint should therefore be compared against the risk of a failed migration, not against the revenue of a clean consumer bank.

This is where BM-Bank's legal boundary does economic work. If VTB directly absorbed every remaining Otkritie, Sarov, Bank of Moscow and predecessor-bank obligation, it might simplify customer branding but also import claims, sanctions problems and enforcement vulnerabilities into the main bank. Public reporting in 2025 explains why that became sensitive. Early in 2025, market commentary still described BM-Bank's integration into VTB by 2026 as the expected final step. Later reporting tied to a London arbitration involving former Otkritie subordinated creditors said that an unchanged merger plan would not proceed.

RBC later reported that VTB backed away from joining BM-Bank and treated another subsidiary as the last bank to be merged. The legal story is not fully public, but the strategic conclusion is clear enough: BM-Bank's separate existence became more valuable once direct integration threatened to move disputed obligations or enforcement paths closer to VTB.

Sanctions strengthen that conclusion. OFAC records list BM-Bank under Russia-related measures and link it to VTB. UK financial-sanctions guidance states that Bank Otkritie ceased when it merged into BM-Bank on January 1, 2025 and that BM-Bank remains designated because it is owned or controlled by VTB Bank. The UK guidance also indicates that licences referring to Bank Otkritie needed amendment after the merger. This means BM-Bank's perimeter is not only a Russian corporate-law matter. It is a sanctions-administration matter for counterparties, customers, creditors and lawyers.

Moving obligations from a designated former Otkritie entity into a VTB-controlled BM-Bank does not cleanse them for foreign sanctions purposes. But keeping them in BM-Bank may preserve a clearer map of which claims belong to the legacy perimeter and which belong to VTB's larger banking operations.

Compliance inside Russia is also visible. The Bank of Russia decisions page records 2025 and 2026 prescriptions requiring BM-Bank to suspend orders or trades for individual clients under securities-market legislation. Those decisions do not prove broad misconduct by the bank. They do show that BM-Bank's securities permissions are not ornamental. The bank is in a position where it must police client orders, depository accounts, brokerage activity and market rules. When combined with the 2024 brokerage and depository licence decisions, the bank's compliance function looks active.

A legacy bank with live securities clients cannot simply become a passive balance-sheet bucket. It must operate controls, records and customer-facing notices with enough quality to satisfy the regulator while avoiding sanctions and legacy-claim mistakes.

The banking function therefore has three layers. The first is balance-sheet stewardship: loans, securities, funds from credit institutions, subordinated debt, DIA-related obligations and capital. The second is customer continuity: deposits, loans, mortgage relationships, cession notices, statements and digital access for customers who may be migrating away. The third is legal isolation: disputed, sanctioned or non-standard claims stay in a bank that can be capitalized and supervised without being immediately swallowed by VTB. The technology footprint supports all three layers. It is not a separate fourth business line.

If the routing, web resources and Open-linked systems are kept alive, they are justified by the need to keep those three layers functioning while the bank either runs down or remains as a permanent subsidiary.

Ownership and support are the hinge. ACRA and NKR both describe extraordinary support from the shareholder or supporting entity as a material rating factor. NKR's rating is especially explicit that group support lifts the rating above the standalone level and that shareholder risk is minimal. UK sanctions guidance reaches the same practical conclusion through a different legal lens, treating BM-Bank as owned or controlled by VTB. The public picture is therefore not ambiguous on control even if every current ownership percentage is not easily visible in one public registry page.

BM-Bank is not a free-standing Russian regional bank choosing its own growth course. It is a VTB-controlled perimeter whose credit standing, funding access, integration path and sanctions status depend on that relationship.

That dependency cuts both ways. Parent support reduces default risk for customers and creditors. It also means BM-Bank's own economics cannot be read without group incentives. A loss-making or low-growth subsidiary might still be rational if it prevents a larger legal loss, preserves deposit confidence, lets the group migrate customers slowly, or keeps enforcement risk away from foreign infrastructure. Conversely, a profitable period may not prove that BM-Bank deserves to remain separate forever if much of the profit comes from securities positions, related-party balances or one-off reorganization effects.

The public numbers through H1 2025 show capital strength and profit, but they do not disclose enough intercompany pricing to separate true standalone returns from group design.

The customer proposition is the weakest part of an independent-bank story. Public product catalogues do not show BM-Bank as a strong current source of retail debit-card or auto-loan offers. The Bank of Russia's payment-services notice explicitly says BM-Bank was not a credit institution significant in payment services after Otkritie joined it. VTB's own notices direct transferred borrowers into VTB accounts and VTB Online rather than trying to deepen BM-Bank relationships.

The natural inference is that BM-Bank's remaining customers are valuable because they must be served, not because they are the target base for a new acquisition campaign. That is an important distinction for anyone evaluating the bank's network and software costs. A bank that is acquiring customers needs scalable product systems. A bank that is migrating and containing customers needs accuracy, reliability, auditability and legal traceability.

The costs of getting that wrong are high. A silent depositor who is not properly notified can become a legal and reputational problem. A non-standard mortgage moved to the wrong servicing structure can create contract disputes. A securities client blocked under market rules needs precise order controls and records. A bondholder whose issuer changed after a merger needs continuity of payment and disclosure. A sanctioned counterparty needs screening and licence interpretation. A network outage affecting old Open or BM-Bank resources may not matter to a growth app metric, but it can matter to legal notices, records access or customer trust.

That is why the technology footprint cannot be dismissed as waste just because it is inherited. Its economic value is defensive and operational.

At the same time, inherited technology can become a trap. The RIPE data shows a landscape of Open, reserve and predecessor-related network resources. Each additional autonomous system, prefix block, route object, registrar contact, web property and upstream relationship creates maintenance duties. The IPinfo and RIPEstat views show no obvious IPv6 modernization in the checked AS records, and some reserve AS records appear inactive or dependent on AS5589. A bank under sanctions and group reorganization pressure has limited tolerance for technical debt.

The retained network perimeter makes sense only if BM-Bank has a credible plan to consolidate, secure and retire what is no longer needed while preserving what customer and legal continuity require. Otherwise the infrastructure becomes another legacy obligation inside a bank already full of legacy obligations.

The bank's securities function makes the technology question sharper. Bank records and bond notices show BM-Bank as successor or issuer in securities contexts, while the Bank of Russia granted brokerage and depository permissions in 2024. Securities servicing is data-intensive. It requires exact positions, event notices, order controls, payment records, identifiers and regulatory reporting. It also interacts badly with sanctions when foreign holders, blocked assets or predecessor-bank claims are involved. That means BM-Bank's technology stack does not need to win app-store rankings to be economically necessary.

It needs to keep records correct across mergers, claims, licences and counterparties. The more complex the successor chain becomes, the more valuable accurate legacy-system continuity becomes, provided the cost is controlled.

The capital and dividend evidence adds another nuance. Corporate disclosure on 2024 profit allocation indicates a large distribution out of 2024 profit while still allocating to reserve and retained lines. A bank can pay dividends and remain well capitalized if its regulatory ratios allow it. But in BM-Bank's case, distributions must be read alongside the parent-support model and the enlarged 2025 boundary. If the bank is a group-controlled container, capital can be moved in or out as part of broader VTB balance-sheet management.

A dividend does not prove the bank is a mature cash cow; it may show that pre-merger profit and capital planning were being aligned before the Otkritie perimeter and subsequent legal complications changed the next step.

The best bull case for BM-Bank is therefore limited but real. The bank has a licence set broad enough to handle banking and securities obligations, a capital base strong enough to absorb a large inherited perimeter, a parent strong enough to support liquidity, a routed network footprint broad enough to maintain continuity, and a clear reason to exist while hard-to-transfer customers and disputed claims are worked through. If VTB can use BM-Bank to transfer easy portfolios, service the rest, avoid legal contagion, and gradually simplify inherited technology, the bank is an efficient operating boundary.

The economics would come from avoided losses, orderly run-off, preserved customer confidence and reduced integration risk, not from conventional revenue growth.

The bear case is also clear. BM-Bank may be carrying the least attractive remnants of several reorganizations: old Bank of Moscow problem assets, residual Otkritie obligations, silent deposits, unusual loans, securities disputes, sanctions restrictions and inherited IT. The strongest customer relationships may already have gone to VTB. Funding may remain concentrated and expensive. Related-party income may flatter profitability. A network footprint inherited from Open and other predecessors may require spending without creating new income.

Legal disputes, especially those linked to former Otkritie subordinated creditors, may keep the entity separate longer than planned. In that scenario, BM-Bank's technology footprint preserves obligations more than it creates economic optionality.

The public evidence favors a middle conclusion. BM-Bank is not a growth franchise in disguise, but it is not useless. It is a lawful, capitalized, technically live bank whose job is to make ugly continuity problems manageable. Its network footprint serves an economic purpose if the alternative is a rushed VTB integration that imports legal risk, breaks customer servicing, loses records or creates sanctions confusion. It fails the test if the retained infrastructure cannot be reduced as portfolios migrate or if it becomes a permanent cost centre with no customer, legal or risk benefit.

The bank's future value depends less on finding new customers than on proving that each retained system, licence and balance-sheet item has a reason to remain outside VTB.

The biggest change-of-view fact is the integration reversal. Before mid-2025, the clean story was: Otkritie and Sarovbusinessbank join BM-Bank, then BM-Bank joins VTB by 2026, ending a chain of subsidiary mergers. After the London arbitration reporting and RBC's later account of VTB backing away from BM-Bank integration, the cleaner story broke. If BM-Bank was only a temporary bridge, its technology and legal perimeter would be short-lived. If BM-Bank cannot be merged without risking VTB's foreign or legal position, its perimeter becomes strategically important.

That one fact changes the meaning of every other fact: the licences, capital, AS records and customer notices become evidence of a bank that may have to remain operational for longer than expected.

A second change-of-view fact is the 2024 securities-licence activity. A casual reading might treat BM-Bank as an old rescue bank waiting to disappear. New brokerage and depository permissions make that harder. The bank is maintaining or refreshing functions that support securities clients and capital-market obligations. That does not make it an investment-bank growth story, but it does show a live controlled function. The Bank of Russia's later client-order suspension prescriptions reinforce the same point: securities controls are part of BM-Bank's actual operation.

A third change-of-view fact is the size of the 2025 balance sheet. A January-to-July increase from about 535 billion rubles of assets to about 1.911 trillion rubles in the Bank of Russia standalone form, plus NKR's comment about 3.83 trillion rubles of consolidated IFRS assets in H1, is too large to treat as immaterial. The bank became a major balance-sheet container even if the economic reason was inherited obligations rather than new demand. For technology and compliance, scale matters. A small shell can be wound down with a lean process. A top-ten-by-assets banking container needs industrial controls.

A fourth change-of-view fact is the routing evidence. If no active AS records were visible, the technology footprint would be speculative. Instead, AS5589 and AS39350 are visible and active, with inherited Open and BM-Bank identifiers, announced prefixes and carrier relationships. That does not say how traffic is allocated among applications or legal entities, and it does not prove network monetization. It does prove that BM-Bank is attached to live infrastructure whose migration, security and retirement decisions matter.

A fifth change-of-view fact is sanctions continuity. Otkritie did not vanish from compliance reality simply because it merged. UK guidance treats Otkritie as ceased but BM-Bank as still designated through VTB control, and OFAC records keep BM-Bank in the Russia sanctions map. That means a legal merger can simplify domestic corporate structure while complicating or preserving foreign compliance burdens. Any assessment of BM-Bank's operating boundary must therefore include sanctions administration, not just Russian banking law.

The principal uncertainties are equally important. Public materials do not disclose precise current customer counts, the full split of silent deposits, the exact economics of each transfer to VTB, detailed technology spending, private intercompany service pricing, the final enforceable exposure from former Otkritie subordinated claims, or all security and data-centre arrangements behind the RIPE-visible resources. It is also unclear from public materials how long BM-Bank will remain outside VTB and whether the group will pursue a modified integration, permanent subsidiary model or extended run-off. Those gaps prevent a clean valuation.

They do not prevent a strategic judgment, because the visible facts all point toward the same operating role.

The actual boundary is therefore best mapped by asking which function would break if BM-Bank disappeared tomorrow. New consumer lending would probably not break; VTB could originate that in its own name. A public mass-market deposit campaign would probably not break; VTB already has the brand and channels. But residual account records, securities successor duties, predecessor-bank contracts, customer notices, regulator-facing reports, sanctions classifications, bond payment mechanics and disputed liabilities could break or become legally blurred. That distinction matters more than the corporate family tree.

BM-Bank's economic perimeter is the set of obligations that still need a bank licence, a record system and a responsible legal person even after the commercially attractive activity has moved elsewhere. The network and software estate should be sized against that perimeter, not against the size of VTB or the historical size of Otkritie.

Ownership makes that perimeter credible but also limits its independence. If BM-Bank were weakly supported, customers and creditors would treat the residual bank as a risk dump. If it were fully merged into VTB, the ring-fence benefit would disappear. The current arrangement sits between those poles: parent support is visible enough for ratings, sanctions control and customer confidence, while legal separateness remains useful enough that the group has not simply absorbed the bank after the 2025 legal complications. That is a narrow balance.

It can hold only while counterparties believe BM-Bank is backed, regulators accept the separation, and the cost of keeping a separate bank is lower than the cost of moving every claim into VTB. The moment any of those assumptions fails, the strategic logic changes.

The funding structure reinforces that dependence. The July 2025 numbers show large funds from credit institutions and a much smaller retail deposit base than a normal customer-bank story would suggest. The DIA rehabilitation exposure adds another non-market creditor whose presence reflects history rather than current customer demand. Subordinated obligations remain large enough to matter. High regulatory liquidity ratios and parent funding access reduce short-term failure risk, but they also mean BM-Bank's funding advantage is not primarily a branch deposit franchise.

It is a mixture of group support, inherited balances, securities-book economics and state-resolution history. In tight monetary conditions, that can still produce profit if assets are high-yielding and capital is ample, but it is not the same as building a durable low-cost deposit base.

Capital should be interpreted through the same lens. A 27.42% total capital ratio at July 2025 looks strong, and it is strong in regulatory terms. But the question is what that capital protects. In a growth lender, excess capital may support future lending expansion. In BM-Bank, it more plausibly protects legal uncertainty, portfolio transfers, securities valuation risk, concentration in group-related positions and the unknown timing of run-off. The shareholder capital increase to 66.401953 billion rubles and the rise in own funds after the 2025 perimeter expansion fit a bank being prepared to hold a much larger and more sensitive book.

Capital strength is therefore a condition for the ring-fence strategy, not proof that the ring-fence will create independent growth.

The customer boundary can be read as a sorting problem. Customers who can be moved cleanly are moved toward VTB, often with notices that preserve contract terms while changing the payment or servicing route. Customers who cannot be moved cleanly stay linked to BM-Bank until documentation, consent, product features or legal questions are resolved. Securities holders and bondholders may not experience the same retail migration, but they face the same successor logic: the issuer or licensed entity has changed, while the economic support expectation remains group-linked. This sorting process creates friction for customers.

It also explains why a bank with limited apparent new-product marketing still needs robust service desks, archives, authentication, statement generation and digital access. The customer experience may be transitional, but transitional customers are still regulated banking customers.

Network concentration is one of the less obvious risks. AS5589's upstreams through major Russian carriers and AS39350's separate upstream map provide reachability, but they also concentrate dependency in a small domestic connectivity set. For a sanctions-constrained bank, foreign cloud substitution, cross-border service support and vendor change are harder than for an ordinary private company. The absence of obvious IPv6 deployment in the checked public AS views is not fatal, but it suggests that the visible perimeter is not being marketed as a modern connectivity platform. Its purpose is continuity.

That makes operational resilience, DDoS protection, certificate control, registrar hygiene and clean ownership of web properties more important than network expansion. A bank can tolerate an unglamorous network if it is secure and well-documented; it cannot tolerate an inherited network whose ownership or control is unclear.

The Open-linked resources are especially important because they connect brand migration to technical migration. The public customer may see Otkritie disappear, BM-Bank become the legal successor and VTB become the servicing destination. Behind that sequence, identifiers, customer files, internet domains, brokerage access, payment instructions and support channels have to line up. If old Open-related network ranges remain active, the economic question is whether they still serve customers and legal records or merely reflect incomplete cleanup.

A prudent group would keep them while customers migrate and claims settle, then retire or consolidate them once no regulated dependency remains. A less disciplined group would let the inherited estate linger, generating security and maintenance cost without reducing risk. Public records show the estate exists; they do not yet prove the retirement discipline.

Compliance obligations also argue for separateness. Former Otkritie sanctions treatment, BM-Bank's own designation, VTB control, securities-order restrictions and deposit-insurance obligations all need clean mapping. When a customer, creditor or counterparty asks who owes what, the answer must be based on legal succession, not on brand familiarity. A separate BM-Bank can make that mapping clearer if records are complete and notices are reliable. It can make the mapping worse if customers are bounced between names and channels without authoritative documents. The same is true for market controls.

A bank with new brokerage and depository permissions has to prove that client restrictions, sanctioned-party screening and order suspensions follow the account, not the vanished brand. Technology is the control layer that makes that possible.

The alternatives are unattractive in different ways. A direct merger into VTB would simplify branding and might cut duplicate technology cost, but public reporting after the London dispute indicates that it could expose VTB to legal or enforcement complications. A pure wind-down would reduce strategic ambiguity, but it could take years if silent deposits, unusual loans and securities claims remain. Portfolio-by-portfolio transfer is safer, but it leaves BM-Bank with the hardest cases and can make the residual bank look weaker over time.

A permanent ring-fenced subsidiary keeps risk contained, but it forces the group to bear duplicate governance, compliance and infrastructure cost. Given the public facts, the most rational path is staged transfer plus disciplined residual operation: move what can move, keep what must stay, and shrink the technology perimeter only when records and claims allow it.

That path creates a measurable burden for management. BM-Bank has to show that operating expenses after the 2025 reorganization are one-time or transitional rather than a new fixed cost base. It has to show that profit does not depend too heavily on opaque group positions. It has to preserve capital while legal disputes and sanctions treatment remain unsettled. It has to keep customers informed without turning the BM-Bank name into a dead end. It has to make the AS5589 and AS39350 footprints safer and simpler over time.

And it has to do all this while outsiders may see only fragments: regulatory forms, ratings notes, sanctions pages, routing records and customer notices. The bank's true performance will be judged by whether those fragments begin to converge toward simplification.

That judgment is this: BM-Bank's surviving technology footprint serves a real economic banking perimeter only when defined defensively. It helps hold legal risk, customer transition, securities servicing and sanctioned obligations in a bank that remains supervised, capitalized and technically reachable. It does not by itself prove durable standalone banking economics. The bank's actual function is to preserve order while VTB decides what can be migrated, what must be serviced, what must be litigated and what must remain quarantined.

If BM-Bank can reduce the inherited network and customer perimeter over time without losing records, breaching obligations or moving legal risk into VTB, the cost is justified. If it cannot, the same footprint becomes an expensive monument to unresolved bank rescues.

The practical test over the next reporting periods is not whether BM-Bank announces a new retail app or a larger branch push. It is whether customer funds and unusual portfolios decline in an orderly way, whether securities obligations remain controlled, whether related-party concentration becomes more transparent, whether operating expenses normalize after the merger year, whether capital remains strong without excessive group subsidy, whether sanctions guidance and legal disputes stop blocking integration, and whether Open-linked network resources are consolidated instead of simply preserved.

Those are the signs that the bank is turning a difficult boundary into an efficient one. Without them, BM-Bank remains what its history warns it could become: a large, well-capitalized place where Russian banking problems are kept alive because absorbing them directly is worse.
