Oil Plunges, Bitcoin Rebounds After Weekend Pause in U.S.-Iran Strikes—But the Rally Hinges on the Fed and a Fragile Ceasefire

Here’s what actually happened in markets, what the ceasefire status really means, and what historical patterns tell us about how long this rally might last.

The Monday Market Moves: Oil Dives, Dollar Drops, Bitcoin Rallies

The weekend halt was a tactical pause, not a formal ceasefire restoration. But it was enough to trigger a sharp reversal in several key markets on Monday morning:

Oil: After 13 consecutive nights of U.S. strikes that pushed Brent crude above $100/barrel by July 24 , the sudden halt caused the immediate supply-disruption premium to unwind. Westpac noted that "market sentiment was supported by reports that Pakistan and Iran were exploring new peace talks" . The drop in crude was the most dramatic single-session move of the conflict.

Bitcoin and Crypto: Bitcoin had been battered by geopolitical pressure throughout July. When the ceasefire collapsed on July 8, BTC slid toward $61,500 . It recovered partially when Iran signaled willingness to negotiate , but remained below $63,000 during the heaviest bombing days . The weekend de-escalation pause changed the dynamic: Bitcoin rose about 1.2% in 24 hours to top $65,000, and Ethereum (ETH) gained more than 3% to nearly $1,950 . Solana (SOL) and XRP also posted gains of 1% to 2% . The total crypto market capitalization increased to $2.29 trillion, up 0.84% .

The Dollar: The U.S. Dollar Index weakened as safe-haven demand faded—a classic pattern when geopolitical tensions ease . A weaker dollar typically provides a tailwind for Bitcoin and other risk assets priced in dollars.

Broader Market Sentiment: Investor confidence broadly improved , though the gains were concentrated in assets that had been most punished by the conflict. Brent crude had already fallen about 4% before markets closed for the weekend, settling near $96.7 , so Monday's 4.7% gap lower extended that move.

Why the Ceasefire Is Still in Tatters

The weekend halt is not a restoration of the 60-day interim ceasefire. That deal—the 14-point Islamabad Memorandum of Understanding, signed on June 17 and mediated by Pakistan—was meant to defer tough issues like Iran's nuclear program and access to the Strait of Hormuz while providing a 60-day window for negotiation . But on July 8, Trump declared it "over," saying he didn't want to engage with Tehran . Renewed U.S. airstrikes followed immediately.

Reuters reported on July 13 that the ceasefire had already been eroding over "disagreements over the Strait of Hormuz and other issues" . Article 5 of the MoU said commercial vessels must have safe passage, but analysts noted its wording was vague . The weekend halt is a tactical pause, not a diplomatic breakthrough: the U.S. and Iran both stopped striking each other, but CENTCOM's naval blockade remains in place .

The difference matters for markets. A tactical pause can be reversed in hours; a restored ceasefire would require verified compliance. As long as the blockade stays and the underlying disagreements over Iran's nuclear program and sanctions remain unresolved, the supply-disruption premium in oil could snap back at any moment.

The Fed Wildcard: July 28-29 FOMC Decision

The Federal Open Market Committee meets Tuesday-Wednesday, with its rate decision announced at 2:00 PM ET on July 29 . The fed funds rate stands at 3.50%–3.75%, where it has been held since January 2026 . As of mid-July, traders saw only about a 10% probability of a hike at this meeting, after June inflation data showed cooling .

But the geopolitical backdrop has shifted dramatically since then. Oil's surge above $100/barrel by late July—driven by the bombing campaign—prompted investors to "sharply increase their bets that a fresh rate hike could come later this year" . By July 24, the CME FedWatch tool showed a 38% probability of a hike at the July meeting, up from 12% a week earlier . Forecasters were split: a Reuters poll of economists found the median expectation was for rates to stay steady, but a separate question showed forecasters were more divided than at any point since the conflict escalated .

The market impact of the decision is clear:

• A rate hold would likely support risk assets including crypto, consistent with a risk-on environment.
• A surprise hike would strengthen the dollar, tighten financial conditions, and pressure Bitcoin—especially if the Fed signals that higher oil prices are feeding into inflation expectations.

What History Tells Us: The "Preparation-Outbreak-Clarification" Cycle

Academic and market analysis of past major geopolitical conflicts—the 1990-91 Gulf War, the 2003 Iraq War, and the 2022 Russia-Ukraine war—shows a consistent three-phase pattern :

• Phase 1 (Escalation/Preparation): Oil and gold spike on uncertainty; equities and risk assets sell off. This is what happened for most of July, especially after July 8.
• Phase 2 (De-escalation/Halt): Oil retreats, the dollar weakens, and risk assets rebound as the supply-disruption premium falls. This is exactly what markets saw on July 27.
• Phase 3 (Resolution or Relapse): If a durable ceasefire follows, risk assets tend to rally further. If fighting resumes, oil spikes again and crypto/dollar reprice sharply.

The current weekend halt fits Phase 2. But the ECB has cautioned that the historical relationship between geopolitical events and oil prices is "not clear-cut" : some shocks produced only brief, small moves in oil. LSE research confirms that geopolitical oil shocks "resemble severe oil supply shocks, leading to production declines and a much sharper increase in oil prices than conventional shocks" . This means the oil price move on Monday—even though large—could prove temporary without a real supply disruption.

For crypto specifically, academic evidence from the Russia-Ukraine and Israel-Gaza conflicts shows Bitcoin has a "noteworthy and positive correlation with gold" (a safe haven) but a "negligible and negative correlation with oil" (a cyclical commodity) . During the Russia-Ukraine war, some studies found Bitcoin offered "lengthier safe haven properties than gold for oil returns" , while other research found crypto's safe-haven role was "weak for stocks and stronger for currencies" .

The Bottom Line: A Weekend Rally Without a Lasting Peace

The weekend halt produced exactly the market response that historical patterns predict: oil down, dollar down, Bitcoin up. But that is only Phase 2. Whether Phase 3 brings a durable ceasefire—or a relapse into full-scale conflict—remains the key unknown.

The FOMC decision adds another layer. If the Fed holds steady, the macro backdrop remains supportive for crypto. If it surprises with a hike, the dollar strengthens and Bitcoin comes under pressure. And if the underlying ceasefire continues to fray, the risk-on rotation could reverse as quickly as it started.

For now, the historical pattern is clear: de-escalation rallies tend to last weeks, not days, but they require a durable diplomatic resolution to sustain themselves . Without that resolution—and with a Fed meeting in 48 hours—the July 27 rally is best understood as a tactical reprieve, not a turning point.
