Why are Bitcoin, Ethereum and XRP Prices Crashing Today: Iran, Trump and the Strait of Hormuz Explained

Bitcoin, Ethereum and XRP tumbled sharply on Sunday after Iran responded to President Trump’s 48-hour ultimatum not with concessions but with an escalation, vowing to fully close the Strait of Hormuz and strike energy, technology and water infrastructure across the Middle East. With 33 hours remaining on Trump’s deadline, markets are pricing in the very real possibility of direct military confrontation.

The total crypto market cap fell 2.31% to $2.36 trillion, wiping roughly $55 billion in value as investors moved swiftly out of risk assets.

What Iran Said

Iran’s response, relayed through senior military commanders, was unambiguous. The country would completely seal the Strait of Hormuz, the narrow waterway through which roughly 20% of the world’s oil supply passes daily.

Strikes on vital regional infrastructure, including energy facilities, IT systems and water desalination plants, were explicitly threatened. Officials added that Iran had stockpiled enough essential goods to withstand up to one year of sanctions pressure, signalling the country has no intention of backing down quickly.

Iran’s military leadership also announced a formal shift in strategy from defensive to offensive operations, a significant change in posture that immediately rattled financial markets worldwide.

The Numbers

Every major cryptocurrency fell in lockstep with equities as the headlines broke.

Bitcoin dropped 2.58% to $68,820, dragging its market capitalisation below $1.38 trillion. Ethereum fell harder, losing 3.36% to $2,082, its steepest single-session drop in weeks. XRP declined 3.04% to $1.39. Solana shed 2.72% to $87.33, and Dogecoin fell 2.82% to $0.091.

The CoinMarketCap Fear and Greed Index hit 27, deep in fear territory. The average crypto RSI across the market fell to 39.59, approaching oversold levels not seen since the early weeks of the Iran conflict. 

Why Crypto Falls When Wars Escalate

The moves reflect a market that has fundamentally repositioned crypto as a risk asset rather than a safe haven. When geopolitical fear spikes, institutional investors reduce exposure across equities, commodities and digital assets simultaneously, rotating into cash and government bonds instead.

Adding to the pressure, interest rate hike expectations are quietly creeping back into market pricing. 

What Happens Next

The next 33 hours are the most consequential for markets in weeks. If Trump extends or softens his deadline, a relief rally across risk assets is likely. If Iran takes any military action before the clock runs out, expect Bitcoin to test the $65,000 level and broader crypto market cap to approach $2.29 trillion, the 78.6% Fibonacci retracement level analysts have identified as critical support.

Macro events this week will add further volatility. S&P Global Services PMI data arrives Tuesday, U.S. crude oil inventory data on Wednesday, initial jobless claims on Thursday, and Michigan Consumer Sentiment on Friday.
