Bitcoin Rally Runs Into Rising U.S. Bond Yields as August Nears Its End

Bitcoin fell to around $77,500, giving back some of its nearly 25% August rally as rising Treasury yields and renewed U.S.-Iran tensions pressured financial markets.

The pullback has put Bitcoin’s recent strength under the microscope, raising the question of whether August’s gains reflected a lasting improvement in the cryptocurrency’s macro backdrop or were largely driven by falling bond yields that have now reversed.

The U.S. and Iran exchanged fresh attacks overnight Tuesday as tensions surrounding the Strait of Hormuz continued to build. President Donald Trump threatened strikes against Iran’s oil infrastructure, while Tehran warned that it could launch additional attacks on U.S. military bases across Gulf countries.

The escalation sent crude prices sharply higher and renewed fears that an energy-price shock could contribute to broader inflation. Government bond yields rose across Japan, Australia, the U.S. and Europe, while traders increased their expectations for a Federal Reserve rate hike at the September policy meeting. Inflation remains above the Fed’s 2% target, adding to the uncertainty surrounding monetary policy.

Much of Bitcoin’s August rally was supported by falling yields. When Treasury yields rise, speculative assets such as Bitcoin can become less attractive as investors gain access to higher returns from traditional fixed-income markets. The same yield trend that helped Bitcoin advance last month is therefore now creating a headwind.

Strategy, the largest corporate Bitcoin holder, resumed BTC purchases after a roughly two-month break. However, the renewed accumulation did little to counter the market-wide selling pressure, underscoring the dominance of macroeconomic factors over corporate treasury demand in the current environment.

The decline also spread across the broader cryptocurrency market. Major tokens moved lower Wednesday after recording strong gains throughout August, with nearly all large-cap assets falling against the dollar.

Solana and the TRUMP memecoin were among the hardest-hit major tokens, while BNB was one of the more resilient assets, losing only about 0.3%. The broad nature of the selloff suggests a general reduction in risk appetite rather than weakness stemming from a specific blockchain or cryptocurrency.

Investors are now awaiting Friday’s U.S. nonfarm payrolls report for clues about the Federal Reserve’s next move. A stronger employment reading could strengthen the case for higher rates, potentially pushing Treasury yields further upward and weighing on Bitcoin and other risk-sensitive assets.

A weaker jobs report could produce the opposite reaction, reducing expectations for a September rate increase and easing pressure on bond yields. Such an outcome could give Bitcoin some of the support it received from falling yields during August, though the market has yet to receive confirmation of that scenario.

Until the employment figures are released, Bitcoin is likely to remain highly sensitive to movements in oil and Treasury markets. Escalating U.S.-Iran tensions and renewed selling in government bonds have shifted investor attention toward macroeconomic risks, leaving crypto-specific developments in the background.
