For anyone confused about what is driving today’s move specifically, two significant events converged at once.

The Largest Options Expiry of 2026

At 08:00 UTC this morning, $14.16 billion in Bitcoin options expired on Deribit, representing nearly 40% of all open interest on the platform. The max pain level – the price at which the most contracts expire worthless – sat at around $75,000, roughly $9,000 above where Bitcoin is currently trading. When that gap exists, positions unwind mechanically and liquidations follow.

Over $115 million in BTC long positions were wiped in a single hour, with $70 billion erased from the total crypto market in four hours.

The technical picture compounds the pressure.

Crypto Patel noted that Bitcoin is forming the same bear flag pattern that preceded its drop from $89,000 to $60,000 in eight days earlier this year. “A daily close below $66,000 could trigger a massive breakdown targeting $46,000,” he said.

Ran Neuner agreed: “The bear flag just broke down. It’s not good. Could go as low as $50k if we don’t bounce soon.”

Iran Threatens a Second Global Shipping Chokepoint

The geopolitical backdrop intensified today as Iran threatened to block the Bab el-Mandeb Strait, the Red Sea gateway through which 12% of global seaborne oil passes, in addition to the Strait of Hormuz, which has been effectively closed since the war escalated.

An Iranian military source said that “the Bab el-Mandeb Strait is considered one of the world’s strategic straits, and Iran has both the will and the ability to create a completely credible threat against it.”

The US Department of Transportation issued a formal advisory on the threat today. If both straits are disrupted simultaneously, the energy route from the Gulf to Europe would be severed end to end.

Gold Up, Bitcoin Down: What the Divergence Shows

Gold is trading at $4,438 today, up 1.36%, while Bitcoin is down nearly 4%. That divergence reflects a pattern that has played out repeatedly since the war began.

When the conflict escalated on February 28, Bitcoin initially fell to $63,106, then recovered to $73,156 within five days as investors rotated out of gold, which had hit record highs above $5,400, and back into crypto. Today that rotation has reversed, with fresh escalation pushing capital back toward traditional safe-haven assets.

Bloomberg Intelligence senior ETF analyst Eric Balchunas described the rotation that drove Bitcoin’s recovery earlier this month: “Traders were like, look, gold had a nice run. Bitcoin’s been beaten up. Let’s rotate into Bitcoin.”

Today, the trade is running in reverse.

What the Data Suggests From Here

Bitcoin ETF outflows hit $171 million on March 26. Ethereum ETFs have now seen seven consecutive days of outflows at $92.54 million, according to Wu Blockchain.

Michaël van de Poppe noted Bitcoin’s weakness heading into month end and said he remains interested in buying in the lower $60K region. The last time Bitcoin dropped sharply on Iran war news, February 28, it recovered 16% within five days. Whether that pattern repeats depends on how the geopolitical situation develops over the weekend.

$66,000 remains the key level. A daily close below it puts the $46,000 bear case in play. A hold keeps the lower $60K range, where at least one major analyst is positioned to buy, as the next significant test.
