A research paper published this week quantifies what happens when bank deposits move at blockchain speed. The number is large enough to reshape how banks fund the economy, and the crypto industry is building the pipes without acknowledging the consequences.
Summary
- A research paper published on August 25 found that tokenized deposits could reduce U.S. bank lending capacity by $580 billion if the technology reaches widespread adoption, roughly 5% of total bank lending.
- The mechanism is straightforward: banks lend against stable deposits, and if deposits can move on chain in minutes instead of days, the deposit base becomes less stable, forcing banks to hold more liquid reserves and lend less.
- LayerZero and Keeta launched tokenized bank deposits across Ethereum, Solana, Base, and Keeta in July 2026, covering nine fiat currencies and making the theoretical risk operationally real.
- The Bank of England endorsed tokenized deposits as belonging in UK payments infrastructure, and South Korea began trialing them for government spending, indicating that adoption pressure is coming from regulators, not just startups.
- The $580 billion figure assumes a moderate adoption scenario. The paper’s high adoption model projects a reduction of $1.2 trillion in lending capacity, a number that would force structural changes to how U.S. banks fund mortgages, small business loans, and commercial real estate.
The crypto industry has spent two years building infrastructure to put bank deposits on chain. The banking industry has spent two years worrying about what happens when it works. A new research paper puts a number on the worry, and the number is large enough that both sides should be paying closer attention.
How bank lending actually works
This section requires explaining something that most crypto coverage skips entirely: the mechanics of fractional reserve banking and why deposit stability is the load bearing wall of the entire system.
When a customer deposits $1,000 at a bank, the bank does not keep $1,000 in a vault. It keeps a fraction, typically 3% to 10% depending on the bank’s risk profile and regulatory requirements, and lends the rest. That $900 or $970 goes to a mortgage borrower, a small business, or a commercial real estate developer. The borrower spends it, and the recipient deposits it at another bank, which lends most of that out again. This is the money multiplier, and it is the engine that converts $22 trillion in U.S. bank deposits into $12 trillion in bank lending.
The system works because deposits are sticky. A customer who deposits money on Monday does not withdraw it on Tuesday. The bank can rely on a statistical floor, the amount that will remain regardless of individual withdrawals, and lend against that floor with reasonable confidence.
