US-Iran strikes spark nearly $1B crypto liquidations

TLDR

Fresh US and Iranian military strikes around the Strait of Hormuz coincided with a sharp risk-off move that wiped out nearly $1 billion in leveraged crypto positions in 24 hours.

1. US strikes inside Iran and IRGC retaliation drove Bitcoin below 73,000 dollars and triggered roughly 900 million to 1 billion dollars of mostly long liquidations.
2. The damage was amplified by crowded long leverage, ETF outflows, and crypto trading like a high beta risk asset instead of a war hedge.
3. Next moves hinge on Middle East escalation, oil and inflation data, and whether leverage and ETF outflows cool before traders re-risk.

Deep Dive

1. Strikes And Liquidation Scale

Multiple outlets report that fresh US airstrikes on Iranian targets near Bandar Abbas and the Strait of Hormuz, followed by Iranian Revolutionary Guard strikes on a US base, rattled markets on 28 May 2026. Reporting from CryptoBriefing describes US strikes on missile sites, boats, and a ground control station near Bandar Abbas and subsequent IRGC retaliation against a US base in Kuwait, framed as a serious warning from Tehran.

In that 24 hour window, data cited by TradingView and Yahoo shows crypto liquidations around 934 million dollars, wiping out about 167,000 trader accounts, with Bitcoin and Ethereum accounting for roughly 363 million and 240 million dollars respectively and the largest single BTC long of about 15.3 million dollars closed on Hyperliquid. CryptoBriefing and other crypto media round this up to about 1 billion dollars of liquidations as Bitcoin slipped below 73,000 dollars and major altcoins like Ether, Solana, and XRP fell 3 to 4 percent, with total crypto market cap down roughly 80 billion dollars in a day.

Confidence: high because independent data aggregators and several major news desks report similar liquidation totals and price levels.

2. Why The Flush Was So Violent

CoinGlass figures cited by TradingView and Yahoo show that around 93 percent of the 24 hour liquidations were long positions, meaning most traders were betting on a rebound rather than further downside. Articles from CryptoBriefing and CryptoPotato note that leverage had built up on the long side after earlier optimism about a ceasefire and US Iran talks, leaving derivatives books vulnerable once war headlines turned negative.

At the same time, spot Bitcoin ETFs had already seen heavy outflows, including a day with about 733 million dollars leaving US spot BTC funds and a 1.3 billion dollar block sale of BlackRocks IBIT shares, which reduced dip-buying capacity when volatility hit. Macro context added pressure: the Gulf conflict has pushed oil toward or above the high 90s to low 100s per barrel, feeding inflation and keeping rate cut hopes muted, which typically hurts risk assets, including crypto.

3. What To Watch From Here

Derivatives metrics still show large but slightly reduced leverage. Aggregate perpetual open interest is around the mid 400 billion dollar range, with a low single digit percentage drop over the last day, which suggests some speculative froth was flushed but not fully cleared. If funding and open interest rebuild quickly while headlines remain tense, another shock could trigger a fresh liquidation cascade.

On the macro side, the same sources highlight three key external drivers: whether US and Iran move back toward a ceasefire, how oil behaves around the Strait of Hormuz risk premium, and how that feeds upcoming inflation prints and central bank rhetoric. ETF flows are the other big tell; if outflows from spot BTC and ETH funds slow or reverse, that would signal returning institutional demand and deeper dip support.

Conclusion

US Iran strikes around the Strait of Hormuz did not just move oil; they flipped crypto into a classic risk-off episode that erased nearly 1 billion dollars in mostly long leverage. The event underlined how crowded positioning, ETF outflows, and macro inflation fears can turn geopolitical shocks into outsized liquidation waves. Until tensions ease and leverage and flows normalize, crypto prices are likely to remain highly sensitive to Middle East headlines and broader risk sentiment.
