The 10-year U.S. Treasury yield pushed past 4.55% Thursday, sending bitcoin below $80,000 for the first time in weeks. The 30-year yield hit 5.12%, a multi-year high. Gold fell to a one-month low near $4,500 as the sell-off swept across asset classes.
The Yield Spike
The move wasn't just U.S. debt — UK gilts, Japanese government bonds, and German Bunds sold off in tandem. The Federal Reserve controls short-term rates, but the long end is set by market expectations on inflation, growth, and fiscal sustainability. Energy-driven inflation keeps the Fed constrained, reinforcing a 'higher for longer' rate regime. Persistent U.S. fiscal deficits require heavy bond issuance at whatever yield the market will accept.
Foreign Holders Pull Back
Foreign holders own roughly 30% of outstanding U.S. Treasuries, and they're reducing exposure. China, the third-largest foreign holder, has cut its holdings from a peak of $1.3 trillion in 2013 to $693 billion, reallocating reserves into gold. Japan, the largest holder at $1.14 trillion, faces repatriation pressure as the Bank of Japan normalizes rates — several of Japan's largest life insurers already cut foreign bond exposure in 2025. That matters for crypto: when long yields spike, risk assets like bitcoin tend to suffer.
Stablecoin Growth and the GENIUS Act
Total dollar-stablecoin supply reached $323 billion as of May 2026, with USDT at $190 billion and USDC at $78 billion. Tether alone holds roughly $117 billion in U.S. Treasury bills. Stablecoin issuers are functionally equivalent to money market funds with global distribution, creating a persistent bid for short-duration Treasuries. The GENIUS Act, enacted with implementation rules due July 2026, restricts payment stablecoin reserves to cash, repo, or Treasuries with maturities of 93 days or less — essentially codifying the current T-bill-heavy structure.
The Long-End Problem
Stablecoin demand can ease front-end funding pressure, but it can't compress long-end yields. The long-end problem remains unsolved — it requires foreign duration buyers that are currently stepping back. For now, the market is watching whether the 10-year yield holds above 4.60% and what that means for risk assets through the summer.
