Key Takeaways:
Bitcoin fell below $77,000 on Sept. 1 as renewed U.S.-Iran military strikes pushed Brent crude above $90 a barrel and lifted 10-year Treasury yields to 4.75 percent, overpowering fresh ETF inflows.
The market-implied probability of a Federal Reserve rate hike at the September meeting rose to 65.4 percent, according to the CME FedWatch Tool, after U.S. forces struck Iranian rocket launchers on Larak Island in the Strait of Hormuz and Tehran retaliated with missile attacks on two U.S. air bases in Jordan.
Ethereum slipped below $2,400 as traders de-risked across digital assets. The 10-year Treasury yield advanced 2.5 basis points to 4.75 percent, its highest since January 2025, while Brent crude settled above $91 a barrel, up more than 3 percent, according to Reuters. The Nasdaq Composite fell 0.5 percent to 26,305.97, erasing roughly $450 billion in market value.
The geopolitical shock has so far outweighed fresh inflows into U.S. spot Bitcoin ETFs, which had provided countervailing buying pressure. If the conflict escalates further, Bitcoin could face continued downside; conversely, de-escalation could allow ETF demand to reassert itself and support a rebound.
Oil and Bond Yields Drive the Risk-Off
The U.S.-Iran escalation, now in its sixth month, has rekindled fears about energy supply disruption through the Strait of Hormuz, a chokepoint for about 20 percent of global oil consumption. Brent crude rose 2.76 percent to $90.47 a barrel following the reciprocal strikes, according to Equiti data, while West Texas Intermediate traded near $87.
Higher oil prices feed directly into inflation expectations, creating a dilemma for the Federal Reserve. Chair Kevin Warsh signaled at Jackson Hole on Aug. 28 that the central bank was ready to act on inflation, which has remained above the 2 percent target for 65 consecutive months. Markets have begun pricing in a potential rate hike by mid-September, raising borrowing costs and pressuring growth-sensitive assets.
The 10-year Treasury yield's climb to 4.75 percent reflects selling pressure on U.S. sovereign debt. Higher discount rates reduce the present value of future cash flows, a dynamic that weighs on Bitcoin and Ethereum, which carry no yield and are sensitive to risk-off positioning.
ETF Inflows vs. Geopolitical Risk
Fresh inflows into U.S. spot Bitcoin ETFs provided countervailing buying pressure, but the geopolitical shock has so far proven dominant. The divergence shows how macro risk-off positioning can temporarily override institutional accumulation.
The broader market reaction shows the scope of the shock. The S&P 500 fell 0.45 percent to 7,677.26, while the Dow Jones Industrial Average dropped 0.58 percent, or 313 points. The STOXX 600 declined 0.6 percent, and the VIX volatility index jumped 5 percent.
For Bitcoin, the key question is whether the current oil-price surge proves temporary or develops into a sustained inflation shock. A rapid easing of geopolitical tensions could provide relief for risk assets, while a prolonged disruption to energy supplies could push inflation expectations and interest rates higher, keeping pressure on crypto prices.
