Cryptocurrency markets are increasingly intersecting with the traditional financial system. While crypto was once viewed primarily as a separate speculative arena, banks, regulators, and central banks now discuss not only the price of Bitcoin, but also stablecoins, tokenized deposits, digital payments, and the impact of crypto assets on bank liquidity.

Why banks are watching crypto more closely
Banks and financial institutions are interested in cryptocurrencies not just due to speculative demand. For the traditional financial system, key areas include fast cross-border payments, asset tokenization, digital forms of currency, new payment instruments, and infrastructure for digital asset operations.
In practice, the main bridge between crypto markets and banks is stablecoins. They are most commonly used as the unit of account within crypto markets. A trader may sell Bitcoin or Ethereum not directly for fiat via bank transfer, but for USDT, USDC, or another stablecoin. This allows staying within the crypto infrastructure, quickly switching between assets, and avoiding delays associated with traditional banking transfers.
For traders, a stablecoin appears as convenient on-chain cash—but for the financial system, it is a far more complex instrument. To maintain its peg to the dollar or euro, the issuer must hold reserves: bank deposits, government bonds, or other liquid assets. Thus, stablecoin stability depends not only on blockchain integrity, but also on the quality of underlying assets, partner banks, reserve liquidity, and regulatory oversight.
Stablecoins as the bridge between crypto and banks
A stablecoin is a crypto asset designed to maintain a stable value relative to an underlying asset—most often the US dollar. In practice, users expect one token to trade near one dollar at all times.
But stability does not emerge automatically—it relies on a backing mechanism. For fiat-backed stablecoins, issuers typically claim to hold reserves in traditional financial instruments: bank deposits, short-term government securities, or other low-risk, highly liquid assets.
In the European Union, this issue is governed by MiCA (Markets in Crypto-Assets Regulation). According to ESMA, MiCA introduces harmonized EU rules for crypto assets—including transparency, disclosure, authorization, and supervision requirements. The European Banking Authority specifically notes that issuers of asset-referenced tokens and e-money tokens must obtain proper authorization to operate in the EU.
For traders, this means one simple thing: a stablecoin is not just a token on a chain. It represents a legal entity, an issuer, reserve holdings, banking partners, regulatory obligations, and trust risk. A weakness anywhere in this chain can rapidly affect the token’s price and market liquidity.
Reuters, in a report dated 28 May 2026, cites Elena Carletti, Deputy Chair of UniCredit and Head of the Bank’s Risk Committee. She warns that Europe may be less capable than the United States of swiftly containing shocks arising at the intersection of crypto assets and the banking sector—due to structural differences in crisis response frameworks.
The Silicon Valley Bank and USDC lesson
One pivotal example of the bank–stablecoin link is the March 2023 collapse of Silicon Valley Bank (SVB) and its impact on USDC.
SVB was a critical banking partner for the tech sector. After its failure, it emerged that part of USDC’s reserves were held at SVB. This triggered market stress: the stablecoin temporarily lost its dollar peg, and participants began mass redemptions.
The U.S. Federal Reserve, in its analysis of the episode, noted that the bank’s failure affected the broader cryptocurrency market—and revealed how decentralized finance (DeFi) protocols interact under market stress.
For traders, this episode matters for three reasons:
- Even large, regulated stablecoins are not fully independent of the banking system. If part of their reserves sits in a bank, that bank’s problems become a direct threat to confidence in the token.
- Peg loss can happen rapidly. During calm periods, a stablecoin may trade near $1 for months—but during stress, participants assess not only the token itself, but also the issuer’s ability to access reserves promptly.
- Stress in one stablecoin can spill over to others. When traders exit one token, they may shift into another stablecoin, Bitcoin, physical USD, or withdraw funds entirely from exchanges—altering liquidity and amplifying intraday volatility.
Reuters also notes that during the SVB crisis, U.S. authorities invoked the systemic risk exception to guarantee all deposits—including those held by crypto firms. As Carletti observed, this helped preserve USDC’s stability—but such a swift, blanket intervention would be far more difficult to implement in Europe.
Why the European model raises distinct concerns
Europe employs a more structured regulatory approach to crypto assets through MiCA. On one hand, this is beneficial: the market gains clear rules, issuer requirements, supervision, and standardized disclosure. On the other, regulation alone does not eliminate systemic risk—if stablecoins become deeply entwined with banks.
Reuters relays Carletti’s view: MiCA requires issuers of e-money tokens to hold reserves in bank deposits or other low-risk, highly liquid assets—effectively binding crypto providers to the banking sector.
At first glance, this appears protective: reserves must be in familiar, liquid instruments. But a new problem emerges. The larger the stablecoin ecosystem grows, the more funds concentrate with issuers—and in the banks where reserves are held. If mass redemptions occur, pressure may hit not only the issuer, but also the banks holding those reserves.
For traders, this means evaluating a stablecoin requires looking beyond market cap and popularity—to regulatory classification, reserve composition, reporting transparency, and the issuer’s jurisdiction.
The ECB’s stance: benefits exist—but so do major risks
The European Central Bank does not deny stablecoins’ utility in payments. Reuters reported on 22 May 2026 that stablecoins are used for cross-border transfers—where traditional bank wires can be costlier—and as settlement units for other cryptocurrencies.
Yet the ECB remains cautious about expanding the euro-pegged stablecoin market. According to Reuters, at an EU finance ministers’ meeting, central bank representatives—including ECB President Christine Lagarde—expressed concern that loosening rules for stablecoins could destabilize bank deposits, weaken the banking sector, and complicate monetary policy implementation.
FAQ
Why are stablecoins considered a systemic risk to banks?
Stablecoins rely on bank deposits and other liquid assets for reserves; if mass redemptions occur, they can strain partner banks’ liquidity—especially when large portions of reserves are concentrated in a single institution, as seen during the SVB collapse.
How does MiCA regulate stablecoins in the EU?
MiCA requires authorization for stablecoin issuers, mandates reserve holdings in credit institutions (30% minimum, 60% for significant issuers), and enforces transparency, disclosure, and supervision—but does not eliminate interdependence with banks.
What did the SVB–USDC incident reveal about stablecoin stability?
It showed that even regulated stablecoins can lose their peg rapidly when tied to a failing bank, triggering contagion across crypto markets and highlighting dependence on traditional banking infrastructure and emergency policy responses.
