Why Mountains of US Treasuries Won't Save Tether and Circle from a Liquidity Crash

The growing reserves of major stablecoin issuers in the form of US Treasury bills create only the illusion of absolute security. Financial analysts warn that in the event of a panicked investor exodus, traditional defensive tools could fail. A liquidity crisis could paralyze the market faster than companies can convert their billions of dollars into actual cash.

The Illusion of 100% Security

Tether (issuer of USDT) and Circle (issuer of USDC) have spent years building user trust by displaying their reserves. Today, a significant portion of these reserves are held in short-term US Treasury bills (T-bills). This move is touted as a guarantee of stability: assets are treated like cash and generate a solid return.

However, experts point to a key vulnerability in this scheme. Reserves are only good when they can be spent instantly. In a stable market, bills are easy to sell or wait for their maturity. But the cryptocurrency industry operates under the laws of extreme volatility, where the situation can change in minutes.

The Mechanics of a Sudden Liquidity Crisis

The main threat to stablecoins is the so-called "bank run." If a mass panic breaks out in the market, millions of users will simultaneously demand to exchange USDT and USDC for real dollars. At this point, issuers will face the following barriers:

1. Time lag of the traditional banking system. Cryptocurrency is traded 24/7. Government bond sales and interbank transfers are tied to the US Federal Reserve's business hours.

2. The problem of market slippage. An attempt to urgently sell tens of billions of dollars' worth of government bonds in a matter of hours will inevitably cause their value to plummet. Issuers will record huge losses, further undermining their solvency.

3. Dependence on custodian banks. The money isn't sitting in the offices of Tether or Circle. It's locked in the accounts of third-party financial institutions, which themselves could become weak links in the chain.

Why the Silicon Valley Bank example has taught us nothing

The history of financial markets is cyclical. The collapse of Silicon Valley Bank (SVB) clearly demonstrated how high-quality and reliable bonds can become dead weight when a bank urgently needs cash to pay depositors. Circle had already lost billions of dollars temporarily stuck in SVB, leading to a short-term depegging of USDC to the dollar. A repeat of this scenario at a deeper systemic level is only a matter of time.

Editor's Opinion

Investors need to break the dangerous habit of treating stablecoins as a fully-fledged equivalent of the fiat dollar. Tether and Circle have effectively become unregulated shadow banks. They take users' money, buy lucrative government securities, and pocket all the interest income, leaving clients with only digital receipts.

Treasury bills provide security against default by the issuer (the US government), but they are physically incapable of protecting against a systemic liquidity crisis within the crypto industry itself. As long as the stablecoin withdrawal architecture is tightly tied to the slow and bureaucratic US banking system, the risk of a sudden freeze of payments or depeg (loss of parity) remains critically high. Prudent asset diversification and avoiding holding all capital in a single "digital dollar" is the only way to protect yourself from a potential storm. Therefore, the Rao Cash editorial team believes that for asset security, it's better to hold funds in several different currencies rather than just one. This will protect you and reduce the risk of future losses.
