“You can see upwards of $6 trillion in deposits flow off the liabilities of a banking system… into the stablecoin environment… they’re either not going to be able to loan or they’re going to have to get wholesale funding and that wholesale funding will come at a cost that will increase the cost of borrowing.” – Brian Moynihan – Bank of America CEO
In the rapidly evolving landscape of digital finance, Brian Moynihan, CEO of Bank of America, issued a stark warning during the bank’s Q4 2025 earnings call on 15 January 2026. He highlighted the potential for up to $6 trillion in deposits – roughly 30% to 35% of total US commercial bank deposits – to shift from traditional banking liabilities into the stablecoin ecosystem if regulators permit stablecoin issuers to pay interest.
Moynihan’s comments arose amid intense legislative debates over stablecoin regulation in the United States. With US commercial bank deposits standing at $18.61 trillion in January 2026 and the stablecoin market capitalisation at just $315 billion, the scale of this projected outflow underscores a profound threat to the fractional reserve banking model. Banks rely on low-cost customer deposits to fund loans to households and businesses, especially small and mid-sized enterprises. A mass migration to interest-bearing stablecoins would cripple lending capacity or force reliance on pricier wholesale funding, thereby elevating borrowing costs across the economy.
This concern echoes broader industry pushback. Executives from JPMorgan and Bank of America have criticised proposals allowing stablecoin yields or rewards, viewing them as direct competition. A US Senate bill aimed at formalising cryptocurrency regulation has stalled amid lobbying from the American Bankers Association, which seeks to prohibit interest on stablecoins. Meanwhile, the GENIUS Act, signed by President Donald Trump in July 2025, marked the first explicit crypto legislation, spurring financial institutions to enter the space while intensifying turf wars as crypto firms pursue banking charters.
Brian Moynihan has led Bank of America since January 2010, steering the institution through post-financial crisis recovery, digital transformation, and now the crypto challenge. A Harvard Law graduate with a prior stint at FleetBoston Financial, Moynihan expanded BofA’s wealth management and consumer banking arms, growing assets to over $3 trillion. His tenure has emphasised regulatory compliance and innovation, yet he remains vocal on threats like stablecoins that could disrupt deposit stability.
The stablecoin phenomenon builds on foundational ideas from monetary theorists and crypto pioneers who envisioned programmable money challenging centralised banking.
These thinkers collectively argue that stablecoins democratise finance, offering transparency, yield, and borderless access. Yet banking leaders like Moynihan counter that without safeguards, this shift risks systemic instability by eroding the deposit base that fuels economic growth.
Moynihan’s forecast spotlights a pivotal regulatory crossroads. Permitting interest on stablecoins could accelerate adoption, potentially reshaping payments, lending, and funding markets. Banks lobby for restrictions to preserve their model, while crypto advocates push for innovation. As frameworks like the GENIUS Act evolve, the battle over $6 trillion in deposits will define the interplay between traditional finance and blockchain.
