Bitcoin was trading around $78,500 as the Japanese yen slipped beyond 160 against the dollar in Tokyo. At the same time, a U.S. attack on Iran’s Larak Island introduced fresh geopolitical uncertainty. The moves followed Friday’s dollar gains and hawkish comments from Warsh at Jackson Hole, which increased market expectations for tighter Federal Reserve policy.
Bond markets were already shifting toward a more hawkish Fed outlook, with investors pricing in a greater possibility of a rate increase. That repricing had helped drive institutional money out of bitcoin ETFs during May and June. The yen is also widely used as a funding currency, allowing investors to borrow in yen and deploy capital into U.S. equities and Treasury markets.
U.S. Treasury Secretary Scott Bessent said Sunday that the yen’s latest moves remained contained and did not justify coordinated intervention by Washington and Tokyo. Reuters also cited Bessent as describing the currency fluctuations as manageable.
Bessent had warned on Friday that an abrupt or disorderly move in the yen could spill over into U.S. interest rates. As a result, developments in Tokyo’s currency market are increasingly being watched alongside Treasury yields, Fed policy expectations and positioning in cryptocurrencies.
Geopolitical Risk Adds to Bitcoin’s Macro Challenge
The U.S. strike on Iran’s Larak Island added another source of volatility to a market already dealing with a weaker yen and changing expectations for U.S. monetary policy.
Oil prices climbed and stocks moved lower following the strike, while bitcoin’s decline was comparatively limited.
BTC Remains Near $78,000
Bitcoin fell less than 1% during the session despite the yen breaking through the closely watched 160-per-dollar mark and renewed tensions in the Gulf region.
Dollar strength remains a central pressure point for crypto markets. The stronger greenback pushed the yen lower while also limiting bitcoin’s upside, keeping BTC around $78,000 as traders assessed multiple risks.
Other major cryptocurrencies posted mixed results. Solana and Dogecoin declined roughly 3% each, while Ether, BNB, Zcash and Tron remained close to flat. Over the previous seven days, Solana was up around 8%, while Dogecoin had lost approximately 10%.
The session also marked the end of August trading. Investors were awaiting the final monthly bitcoin ETF figures to determine whether the recent eight-day run of net inflows had remained intact despite the renewed shift in rate expectations.
Attention is also turning toward major U.S. economic releases. Upcoming nonfarm payrolls and consumer inflation data could influence expectations for the Federal Reserve’s September meeting. Meanwhile, August’s final bitcoin ETF flow numbers may provide a more immediate gauge of crypto investor demand.
For bitcoin, the direction of the U.S. dollar, movements in the yen around intervention-sensitive levels and expectations for Federal Reserve policy remain three major forces shaping the near-term market outlook.
