Banks Just Opened a Backdoor Into Crypto Trading — and They’ll Avoid ‘Holding the Bag’

What changed and why it matters to banks, exchanges and token holders

The U.S. banking regulator announced a change that lets national banks sit between buyers and sellers of crypto without technically owning the coins. For users, that means your bank could soon route and settle crypto trades, move tokens between wallets, and offer a custody-like service — all while claiming it never took legal title to the assets.

Why this matters: it hands legacy banks a new revenue stream — trading fees, settlement fees, and what looks like custody income — while reducing the credit and operational risk that made them shy of crypto until now. For crypto exchanges and OTC desks, it brings a much larger player into the middle of trades. For token holders, it changes who you trust with execution and custody and may narrow spreads and boost liquidity on popular tokens.

But this is not a clean handoff. The move creates a set of carefully drawn operational models that banks will use to avoid being deemed the owner of tokens. That legal tightrope is the main story: banks can profit from crypto flow, but regulators and competitors will push back hard.

Exactly what banks are allowed to do — and how they’ll avoid “holding the bag”

The ruling authorizes national banks to intermediate trades in a few specific ways. First, banks can act as settlement agents: they can match buyer and seller instructions, coordinate transfers across wallets and payment rails, and record those transfers on ledgers or blockchains. Second, banks can offer “settlement risk mitigation” — short-term facilities that reduce the time between trade execution and final transfer, similar to how they handle fiat securities today.

Crucially, banks will lean on three operational models that keep legal title with customers or third parties. One is a “custody-lite” model: the bank controls keys or signing authority for a short window to execute trades, but legal ownership stays with a customer token account at a third-party custodian. Another is third-party custody frameworks where the bank routes and reconciles flows while a licensed custodian — either a specialist or another bank — holds the asset. The third is pure agency settlement: the bank never touches private keys or tokens; it only authorizes and records on-chain movements instructed by customers.

To avoid taking ownership, banks will rely heavily on contracts, audit trails, and technical segregation of keys and accounts. Expect elaborate messaging standards, multi-party signing, and custody agreements that say clearly the bank is an intermediary, not a holder. Operationally, banks will also use short settlement windows and prefunded accounts to limit exposure — they will be pipes and matchmakers more than owners.

Who benefits, who loses, and what this does to liquidity and spreads

Near term, big commercial banks with active custody and payments businesses stand to gain. Think JPMorgan (JPM), Bank of America (BAC), Citigroup (C), and Wells Fargo (WFC) — they can plug crypto intermediation into existing client rails, charging per-trade and custody-like fees. Custodians such as BNY Mellon (BK) and State Street (STT) could also win by providing the actual hold-your-keys layer.

Crypto-native venues and OTC desks like Coinbase (COIN) face immediate competitive pressure. Banks can undercut spreads by using superior balance-sheet plumbing and existing client networks. That should tighten spreads and improve liquidity for major tokens, benefiting liquid, high-market-cap coins. But smaller tokens will still trade primarily on native venues because banks will limit exposure to well-known assets to manage regulatory and reputational risk.

For listed players and ETFs, the story is mixed. Banks’ trading and settlement fees are incremental revenue, but the move also accelerates competition for custody and trade flow from pure-play crypto firms. That suggests a a near-term winners list among listed banks and custodians, while some crypto-platform equities may face margin pressure unless they pivot to higher-value services like market-making or derivatives.

Regulatory landmines: why this won’t be a clean runway

This change doesn’t remove bigger regulatory fights. The SEC still asserts authority over many token offerings and trading activities; state regulators and FinCEN will watch money-transmission and anti-money-laundering rules closely. The broker-dealer vs. bank licensing line is another flashpoint — if bank intermediaries begin to perform broker-like functions, securities laws and broker-dealer rules will become relevant quickly.

Expect litigation and agency pushback. Crypto firms and consumer groups may sue or petition for clearer limits on what banks can intermediate. Congress or the SEC could respond with rulemaking aimed at closing perceived loopholes. State banking regulators may impose conditions that vary by state, forcing banks to build complex, state-aware architectures. Political risk is meaningful: if a high-profile misuse or loss happens, regulators could move to curtail bank activities fast, hitting near-term revenue.

Practical signals and a watchlist for investors and traders

Investors should watch a few clear signals. First, filings and product announcements from big banks saying they will route or settle crypto trades are a near-term revenue signal — look for pilot programs and fee schedules. Second, custody partnership deals (banks partnering with BK, STT, or crypto custodians) show how banks plan to avoid legal ownership. Third, trading volumes and spreads on major token pairs should compress if banks actively intermediate.

Watchlist tickers: JPM, BAC, C, WFC, BK, STT for banks and custodians; COIN for crypto-native platforms; GBTC as a proxy for institutional retail flows. Metrics to monitor: trading fee income in quarterly results, custody assets under custody, and any regulatory filings referencing crypto servicing. Timing: expect pilots and partnership news in the next 3–9 months, with meaningful revenue signals only in the next 6–18 months as banks scale cautiously.

Overall: this is a win for banks’ fee pools and for token liquidity, but it opens a regulatory and reputational minefield. Investors should favor banks and custodians that move fast but prudently, and be skeptical of crypto platforms that rely solely on trading spreads for profit as big banks enter the middle.
