While most traders were sleeping, the US military struck Iranian targets near the Strait of Hormuz. By the time markets opened, Bitcoin had fallen below $73,000 and nearly $1 billion in leveraged positions had been wiped out. This was not a routine dip. This was a war premium getting priced in fast.
What Triggered the Drop
US Central Command confirmed strikes on Iranian missile sites and drone launch facilities near Bandar Abbas in southern Iran. Four Iranian attack drones targeting commercial shipping were shot down. The US Treasury followed up with fresh sanctions on Iranian entities tied to Strait of Hormuz operations.
The ceasefire that markets had been pricing in since April? Gone. Tehran called the strikes a direct violation and vowed a response. That single shift in sentiment was enough to flip the crypto market into full risk-off mode. Dollar and gold demand strengthened immediately. Equities, oil, and crypto all moved at once, just in different directions.
This did not happen in a vacuum. The broader US-Iran conflict has been escalating since February 2026. Markets had been bouncing between ceasefire optimism and war fear for months. Each time a deal looked close, Bitcoin recovered. Each time strikes resumed, it sold off. Today's move is the sharpest version of that pattern yet.
The Liquidation Numbers
CoinGlass data puts total liquidations at $958.8 million over 24 hours across 167,706 traders. Long positions accounted for $897 million of that total, a 93% long-skew on a near-billion-dollar flush. Bitcoin led with $386 million in liquidations, followed by Ether at $246 million. The largest single liquidation was a $15.34 million BTC position on Hyperliquid.
That 93% figure tells you everything. Traders were positioned for a recovery. The market moved the other way. Stops got hit, margin calls followed, and the cascade did the rest. Ether fell 4.2% and broke below $2,000 for the first time in roughly two months. Solana dropped 3.5%, XRP slid 3.6%, and Dogecoin lost 3.2%. The only major that held a weekly gain was Hyperliquid, down 4.5% on the day but still up 2.4% on the week.
Rapid liquidation cascades feed on themselves. Forced selling triggers stop losses, which trigger more forced selling, which pushes price through the next support level, which triggers the next wave of margin calls. Once Bitcoin broke below $74,000, leveraged longs stacked just above that level got flushed simultaneously. That is not a market making a decision. That is a machine running a script.
Why the Strait of Hormuz Matters for Bitcoin
Roughly one fifth of the world's daily oil supply passes through the Strait of Hormuz. Any disruption there does not stay local. It pushes oil prices up, which pushes inflation expectations up, which pushes rate expectations up, which drains appetite for risk assets across the board. Bitcoin sits at the far end of that chain.
Oil surged well above $100 per barrel in the aftermath of the strikes. That is not just a headline number. Higher energy costs feed directly into inflation data, which feeds into Federal Reserve decisions. The Fed's 2026 bull case for Bitcoin rested on rate cuts being the next move. Fed minutes released this week made clear that assumption is no longer safe. One Fed governor already floated the possibility of rate hikes. A sustained conflict near Hormuz keeps that scenario on the table.
Iran has also been requiring ships transiting the strait to pay a toll in digital assets, roughly $1 per barrel. That detail has added a crypto-native dimension to a conflict that is fundamentally about oil and geopolitical leverage. It has not moved prices on its own, but it keeps crypto directly in the frame of a story that would otherwise have nothing to do with it.
The Technical Setup Made It Worse
Bitcoin had already lost its 100-day and 50-day EMAs before the strikes hit. Apparent demand had fallen to 2026 lows according to CryptoQuant data. Binance BTC inflows had nearly tripled in under two weeks, a signal of rising sell pressure building well before today. The $74,000 support level had been holding, but only barely, and with low conviction.
The RSI on the 1-hour chart dropped to single digits during the move. MACD was deeply negative. Price closed below all three major EMAs. The last time demand metrics were this weak was December 2025, which preceded a 33% drop to below $60,000 in early February 2026. That comparison is worth keeping in mind, not as a prediction, but as context for how much damage weak demand plus a macro shock can do.
Spot trading volume has dropped to multi-week lows in recent days, reflecting reduced conviction from both retail and institutional traders. When volume dries up and price is already below key moving averages, a geopolitical shock does not need to be large to cause an outsized move. Thin liquidity amplifies everything.
Institutional Money Was Already Leaving
The ETF picture has been deteriorating for weeks. US spot Bitcoin ETFs recorded six consecutive days of net outflows heading into today, with more than $1.55 billion leaving the sector since May 14. Net inflows for all of 2026 have now fallen to just $536 million. Even BlackRock's IBIT, the dominant player in the ETF market, has slowed considerably compared to 2025 levels.
Ethereum ETFs have been hit harder, with ten consecutive days of outflows totaling over $467 million. Jane Street reportedly cut Bitcoin ETF exposure by roughly 70% in Q1. Goldman Sachs trimmed its Bitcoin ETF holdings by around 10%. These are not retail panic moves. These are institutional portfolio decisions made ahead of the event that just happened.
When smart money reduces exposure before a macro shock and the shock arrives, there is no institutional buying power waiting to catch the falling price. That is part of why $74,000 broke so cleanly.
What Comes Next
The key levels to watch are $74,000 on the upside and $70,000 on the downside. If Bitcoin reclaims $74,000 and holds it, the liquidation event may be absorbed and the market can stabilize. If $70,000 breaks on sustained selling, the next meaningful support sits closer to $65,000, with the 2026 lows near $60,000 back in view after that.
A deal between the US and Iran remains the single most bullish catalyst available right now. It would remove war risk, bring oil prices down, reduce inflation pressure, and push rate hike expectations back off the table. Bitcoin recovered sharply during previous ceasefire windows this year. The same playbook would apply if a genuine agreement is reached.
US-Iran tensions are not resolving this week. ETF outflows have been consistent. The Fed is not signaling cuts. Until at least one of those factors reverses, bounces should be treated with caution rather than conviction.
Watch daily ETF flow data. Watch oil. Watch any headlines out of Iran ceasefire negotiations. Those three signals will telegraph Bitcoin's next move before the price chart does.
