Bitcoin Rewarded 1 of 2 US Interventions. Bessent Just Promised More

Bitcoin (BTC) has traded through two US market interventions in under three weeks. It moved the opposite way each time. Support for the yen pushed it down. An attack on long yields lifted it 8.8%.

Treasury Secretary Scott Bessent went further on Thursday. He said buybacks could exceed $4 billion per issue and would become routine, while denying that rates drove the decision.

Two Interventions, Two Opposite Bitcoin Reactions

The pattern is narrower than it looks. Bitcoin does not reward intervention itself. It rewards the intervention that lowers long-dated US borrowing costs.

The first landed at the start of August. Japan bought its own currency with an estimated $53 billion. The New York Fed then bought yen for the Treasury on August 1.

Washington had not bought yen since 1998. Bitcoin still slipped toward $63,000, down 1.25%, while US stocks closed higher.

Leverage explains why Bitcoin absorbed the yen shock alone. Traders borrow cheaply in yen to buy higher-returning assets, a strategy called the carry trade.

When the yen jumps, those positions cost more to hold. Crypto sits at the riskiest end of that chain, so it sells first.

The decisive detail sits in the bond market. Long yields never fell that week. The 10-year finished near 4.74%, its highest since January 2025, while the 30-year held near post-2007 highs.
