Standard Chartered flags $500B stablecoin bank risk

TLDR

Standard Chartered estimates that up to $500 billion of bank deposits could migrate into stablecoins by 2028, potentially reshaping how dollars move between banks and crypto.

1. Standard Chartered projects that if stablecoins reach about $2 trillion in market cap by 2028, roughly one third could come from developed market bank deposits, implying around $500 billion of outflows from banks.
2. The bank argues that regional US lenders, whose profits rely heavily on deposit funded net interest margin income, are the most exposed if payments and balances move onto stablecoins.
3. Other analysts and policymakers say large scale deposit flight is still mostly theoretical today, so the impact will depend on stablecoin growth, reserve choices, and upcoming US stablecoin laws.

Deep Dive

1. How The $500B Is Calculated

In a recent research note, Standard Chartereds Geoff Kendrick estimates that as stablecoins grow, bank deposits will fall by about one third of total stablecoin market cap. With a projected stablecoin market of about $2 trillion by 2028, the bank sees roughly $500 billion of deposits leaving developed market banks for stablecoins, and a larger amount from emerging markets, according to summaries from CoinDesk and Reuters.

Current dollar stablecoin supply is around $300 billion, so this is a forward looking scenario, not an immediate shock. The bank frames this as a structural shift, not a classic bank run, where increasing use of digital dollars slowly cannibalizes deposits.

2. Why Regional Banks Are Most Exposed

Standard Chartered focuses on net interest margin (NIM), the spread between what banks earn on loans and what they pay on deposits, as the key vulnerability. Regional US banks get a large share of their revenue from NIM, while big diversified and investment banks rely more on fees and markets.

The report highlights that if customers hold more value in stablecoins for payments and short term storage, rather than in checking or savings accounts, regional banks could see both deposits and NIM pressured. Because major issuers like Tether and Circle keep most reserves in US Treasuries rather than bank deposits, much of that money does not recycle back into the banking system.

3. How Real The Risk Seems

So far, several observers note little hard evidence that stablecoins have already drained significant deposits from US banks. US bank deposits recently hit record levels even as stablecoins grew, and some experts argue current usage is still concentrated in trading and cross border flows rather than everyday US retail banking.

There is also disagreement on the size of the stablecoin market by 2028, with some banks forecasting a much lower cap than $2 trillion, which would scale the risk down. At the same time, US legislation such as the CLARITY or GENIUS style stablecoin bills will shape whether stablecoins can pay yield and how attractive they become relative to bank deposits.

Conclusion

Standard Chartereds warning frames stablecoins not just as a crypto tool but as a potential competitor to core bank funding if adoption accelerates. For crypto users, the takeaway is that stablecoins are moving into the center of the banking and regulatory debate, and future rules on yield, reserves, and who can issue digital dollars will be critical for both bank stability and stablecoin growth.
