A surprise geopolitical breakthrough just gave crypto markets exactly the kind of catalyst they’d been waiting for. Trump’s announcement of a peace deal with Iran, which includes reopening the Strait of Hormuz, sent risk assets flying on Monday, and digital currencies were no exception.

Bitcoin jumped roughly 4.4% over 24 hours, climbing from around $63K to near $67K. The altcoin rally was even more dramatic, with Ethereum and Solana both posting double-digit percentage gains.

The numbers tell a clear story

Here’s the thing about crypto rallies tied to macro events: they tend to lift everything, and the riskier the asset, the bigger the bounce. That pattern played out almost textbook-style here.

Ethereum surged 9.9% over 24 hours, pushing above $1,800. Solana outpaced it with a 10.5% jump, landing near $74. XRP climbed past $1.25.

Bitcoin’s move was comparatively modest at 4.4%, but when your base price is north of $60K, a few percentage points still translates to roughly $4,000 per coin. Over a seven-day window, Bitcoin is up about 4.5%, suggesting most of the move was concentrated in the immediate aftermath of the announcement.

The rally happened against what can only be described as a deeply pessimistic backdrop. The Fear and Greed Index, tracked by Alternative.me, sat at 20 at the time of the move, still firmly in “Extreme Fear” territory. For context, it was at 8 just a week earlier. Moving from 8 to 20 is progress, sure, but it’s the kind of progress where you’ve gone from “existential dread” to merely “quite scared.”

That extreme fear reading matters because it means there’s a lot of sidelined capital. When sentiment is that depressed and a positive catalyst hits, the resulting move can be amplified because shorts get squeezed and fence-sitters rush in simultaneously.

Why the Strait of Hormuz matters to crypto

If you’re wondering what a narrow waterway between Iran and Oman has to do with your Solana bag, the answer is oil. The Strait of Hormuz is the single most important chokepoint for global petroleum shipments. When tensions around it escalate, energy prices spike, which feeds inflation fears, which makes central banks more hawkish, which crushes risk assets.

In English: peaceful Strait of Hormuz means cheaper oil means less inflation pressure means a friendlier environment for speculative assets like crypto.

The deal effectively removes one of the biggest geopolitical risk premiums that had been hanging over global markets. Energy markets had been pricing in the possibility of disruption to oil flows through the strait, and that uncertainty rippled into everything from equities to digital assets.

Trump’s deal to reopen the strait is, in market terms, a pressure release valve. Risk appetite comes back, and crypto is one of the first places it shows up because the market trades 24/7 and reacts faster than traditional equities.

What this means for investors

The immediate reaction is clear: markets liked this. But investors should be thinking about whether this move has legs or is simply a sentiment-driven spike that fades in a few days.

Look at the category-level data. DeFi, which was the top-performing sector over a seven-day window, still showed essentially flat returns at 0.0%, according to CoinGecko. That tells you the broader crypto ecosystem was deeply in the red before this geopolitical catalyst hit. The current rally, as impressive as the 24-hour numbers look, is recovering ground that was lost during a brutal stretch of selling.

The Fear and Greed Index still reading “Extreme Fear” at 20 even after this rally is worth paying attention to. In past cycles, sustained recoveries typically don’t begin until sentiment climbs at least into “Fear” territory (around 25-45). The market moved in the right direction, but it’s starting from a deep hole.

There’s also the question of follow-through on the deal itself. Geopolitical agreements have a history of being announced with fanfare and then unraveling in implementation. If details emerge suggesting the deal is less comprehensive than initially presented, markets could give back some of these gains quickly.

For traders, the altcoin outperformance is the signal worth watching. When ETH and SOL gain at more than double Bitcoin’s rate, it suggests risk appetite is genuinely returning, not just Bitcoin acting as a safe haven within crypto. That kind of broad-based rally, where the riskiest assets gain the most, is typically what you want to see at the start of a sustained move higher.

The counterargument: a Fear and Greed reading of 20 with prices still well below recent highs suggests the market remains fragile. One piece of bad news, whether it’s a deal complication, an unexpected inflation print, or a regulatory headline, could send everything right back to where it started. Crypto doesn’t need much of an excuse to sell off when sentiment is this brittle.
