Bitcoin Whipsawed as U.S.-Israeli Strikes Hit Iran

Bitcoin became an immediate market gauge for a major geopolitical shock on February 28, 2026, when the United States and Israel began coordinated strikes against Iran. Coinbase Exchange’s BTC-USD spot market fell from a $65,859.93 UTC-day open to $63,019.60, then reversed and closed the same UTC session at $66,967.85.

The two-way move mattered because February 28 was a Saturday. Major U.S. equity and bond markets were closed, while bitcoin remained continuously tradable. Crypto therefore supplied visible price discovery as investors confronted the possibility of a wider conflict near strategically important energy and shipping routes.

The shock reached Bitcoin within hours

U.S. Central Command said Operation Epic Fury began at 1:15 a.m. Eastern time on February 28. Its contemporaneous release said U.S. and partner forces struck Iranian command-and-control facilities, air defenses, missile and drone sites, and military airfields. An Israel Defense Forces briefing separately described a joint operation with the U.S. military, which Israel called Operation Roaring Lion.

Those releases establish that the military operation began on February 28 and that both governments described it as coordinated. Assertions about individual targets, damage and operational success remained claims by combatant parties and were not independently verified for this reconstruction.

CoinDesk reported at 1:56 a.m. Eastern that bitcoin had approached $63,000 after the strikes began, a decline of roughly 3% over several hours. Its report was updated at 10:05 a.m. Eastern after bitcoin briefly reclaimed $65,000 and then traded near $64,700. These observations documented the initial risk-off response and an early rebound, but they were point-in-time readings rather than a universal market close.

One venue recorded a 7.5% intraday range

Coinbase’s daily candle for the BTC-USD spot pair, measured from 00:00 through 24:00 UTC on February 28, opened at $65,859.93, reached a $63,019.60 low, climbed to a $67,761.55 high and closed at $66,967.85. Coinbase recorded 9,093.24916408 BTC of volume in that bucket.

Coinburn calculations from those figures put the low 4.31% below the open. The close was 6.27% above the low and 1.68% above the open. The high-to-low range was 7.52%. These calculations describe one exchange and one dollar-denominated spot pair; they are not consolidated global-market returns.

Coinbase also warns that historical candles can be incomplete when an interval contains no trades. That warning is less consequential for an actively traded daily BTC-USD bucket, but the dataset still lacks the authority of a regulated consolidated tape. Crypto exchanges maintain separate order books, and bitcoin has no universally binding daily settlement price.

What the reversal did—and did not—show

The sequence supported a narrow conclusion: bitcoin initially behaved like a risk asset during the opening shock, but buyers subsequently recovered the decline before the UTC day ended. It did not establish that bitcoin had become a geopolitical safe haven, nor did the positive close prove that markets expected a short conflict.

Continuous trading made bitcoin a weekend pressure valve, but it also exposed the market to thinner liquidity and rapid headline-driven repricing. The surviving records cannot separate spot selling, derivatives activity, automated orders and discretionary positioning or assign each force a share of the move.

As of February 28, the duration of the military operation, its effects on energy markets and the response of conventional markets when they reopened remained unknown. The defensible event-day record is the whipsaw itself: an abrupt fall toward $63,000 followed by a recovery that left Coinbase BTC-USD above its UTC open.
