The flagship cryptocurrency experienced a significant downturn on Monday as escalating tensions between Washington and Tehran sent ripples through global financial markets. BTC plummeted more than 2% to reach $77,161 at its lowest point before staging a modest recovery to approximately $77,813.
Bitcoin (BTC) PriceThe market turbulence followed American military operations targeting two IRGC missile launch sites located on Larak Island within the Strait of Hormuz. Tehran’s response included launching ballistic missiles directed at several American military installations throughout the Middle Eastern region. According to Fox News coverage, defense systems successfully intercepted nearly all projectiles, with no significant infrastructure damage reported.
The US Central Command (CENTCOM) disputed Iran’s characterization of the American operation as unprovoked aggression, stating that military personnel executed “limited, precise action” targeting minelaying activities that presented an “imminent threat” to regional security.
Energy markets demonstrated immediate sensitivity to the developments. Brent crude futures advanced over 2% to surpass $90 per barrel, while West Texas Intermediate crude jumped above $85.50. Goldman Sachs analysts had previously indicated that petroleum flows through the Strait of Hormuz had stabilized at approximately two-thirds of typical capacity.
The cryptocurrency had momentarily rallied above $79K on initial news reports, but Tehran’s military response reversed those gains. Trading volumes expanded by 50% across 24 hours, indicating intensified market participation.
Treasury Market Dynamics Create Additional Headwinds
Separate from Middle Eastern geopolitical developments, the cryptocurrency faced additional resistance from fixed-income markets. The 10-year Treasury yield advanced to 4.76%, representing the highest reading since January 2025. Meanwhile, the 30-year yield touched 5.269%, positioning just six basis points beneath its peak level from January 2007.
Treasury Secretary Scott Bessent informed CNBC that his department had not yet implemented measures to stabilize long-duration yields. Despite announcing plans to expand debt buyback operations to $4 billion starting in September—double the previous amount—yields continued their upward trajectory.
Prominent investor Ray Dalio publicly advocated for reducing bond allocations while increasing gold positions, with “a bit of Bitcoin,” as protection against potential American sovereign debt challenges.
The dollar index strengthened to approximately 99.6, creating additional obstacles for digital asset valuations. American equity indices also declined, with both the S&P 500 and Nasdaq registering losses near 0.4%.
Technical Analyst Highlights Concerning RSI Pattern
Market analyst Rekt Capital identified a concealed bearish divergence pattern in Bitcoin’s daily Relative Strength Index, cautioning that continued formation of lower highs in the daily RSI could indicate “mounting weakness.” The daily RSI reading stood at 70.7 on Monday, remaining within overbought territory.
Analyst CryptoXLarge shared observations on X noting that Bitcoin has historically never recorded a green September immediately following a positive August performance, describing this pattern as a “historical extreme” warranting attention as September commences.
Bitcoin’s 50-week exponential moving average positioned at $77,269 represents a crucial support threshold according to market analysts. BTC futures open interest expanded by 0.65% to reach $53.88 billion during the final trading hour, with derivative markets showing evidence of accumulation activity.
American spot Bitcoin exchange-traded funds registered $217 million in net accumulation on August 31, with BlackRock’s IBIT product leading the inflows at approximately $206 million.
