Bitcoin fell below $77,000 on May 18, dragged down by a convergence of macroeconomic and geopolitical pressures. Trump published a direct military threat against Iran, sending oil prices higher and pushing 30-year U.S. Treasury yields to their highest close since 2007. In 24 hours, $563 million in long positions were liquidated. Bitcoin ETFs recorded $1 billion in net outflows over the week, ending a six-week streak of continuous inflows.
Key Takeaways
- Bitcoin drops below $77,000 under the combined pressure of Trump’s Iran threat, rising oil prices, and yields at 5.13%
- $563 million in longs liquidated in 24 hours, $1 billion in net Bitcoin ETF outflows over the week
- Markets now price out any Fed rate cut before July at the earliest
Trump, Iran, Oil: Three Triggers at Once
The correction did not come from a crypto-specific event. Trump published a direct military threat against Iran, immediately pushing oil prices higher and triggering a flight toward bonds. The 30-year U.S. Treasury yield reached 5.13%, its highest closing level since 2007. When long-term rates climb at that pace, the opportunity cost of holding Bitcoin, a zero-yield asset, rises mechanically.
Three factors hit simultaneously: rising oil (an inflationary signal), climbing Treasury yields (tightening financial conditions), and geopolitical uncertainty (risk-off sentiment). Bitcoin absorbed all three within hours. Prediction markets now assign an overwhelming probability to the Fed holding rates unchanged through at least July, eliminating any near-term catalyst for a liquidity injection that could support crypto markets.
The context makes the drop even more striking. Just ten days ago, Bitcoin whales on Hyperliquid were carrying their highest net long positions of 2026, a powerful bullish signal that macro forces have now swept aside. Our May 8 analysis documented that institutional accumulation in detail.
Markets reacted without delay. BTC fell from above $83,000 earlier in the week to below $77,000 in a matter of days, a drop of more than 7%. Ethereum and Solana followed, with most major tokens losing between 5% and 10% over the period.
$1 Billion in ETF Outflows in a Single Week
The ETF channel, which had been one of the main pillars of Bitcoin demand since early 2025, is now showing cracks under macro pressure. U.S.-listed spot Bitcoin ETFs recorded approximately $290.4 million in net outflows on May 15 alone, interrupting a six-week streak of consecutive inflows. Over the full week, cumulative net outflows reached $1 billion. Ethereum ETFs added $65.7 million in losses over the same period.
This reversal is significant. In early May, when Bitcoin was approaching $82,000 with record institutional ETF inflows, the dominant narrative was one of continuously expanding institutional appetite. Our May 6 analysis described that institutional comeback as a structural signal. This week’s numbers show that institutional capital can exit just as fast as it enters when macro conditions turn hostile.
The $1 billion outflow figure puts the ETF market’s resilience to a real test. If inflows do not resume quickly, the demand floor that ETFs have provided to Bitcoin since early 2025 could erode, removing one of the key support mechanisms the market has relied on.
Ethereum ETFs also suffered $65.7 million in outflows, confirming that the withdrawal is not limited to Bitcoin. The entire crypto asset class is being hit by the same institutional repositioning in response to the macro shock.

What the Correction Changes for Holders
In the short term, the key level to watch is $76,500, the support institutional players have been defending in recent weeks. A weekly close below that threshold would technically confirm the break of the recent trading range and could open the path toward $73,000 to $74,000.
Over the medium term, the structural question is whether this correction is macro-driven and therefore temporary, or whether it marks the end of the recovery cycle that began in April. Two scenarios stand out. If the Fed signals a rate cut at its July meeting, or if Trump de-escalates toward Iran, either trigger could produce a sharp BTC reversal. If neither materializes, the market could consolidate between $73,000 and $80,000 for several weeks.
For holders, a concrete benchmark exists. Tom Lee of Fundstrat identified a May close above $76,000 as confirmation that the bull cycle remains intact. That level is now under threat from below, and fewer than two weeks remain for the market to defend it.
