President Donald Trump confirmed on April 22 that the United States would prolong the truce with Iran by about 60 days. Tehran's leadership is now expected to finalize a unified proposal for broader de-escalation. The extension builds on a Pakistan-brokered agreement first reached on April 8.
The Council on Foreign Relations reported that Trump "announced an extension to the U.S. Iran truce yesterday to allow Iranian leaders to reach a 'unified proposal' in talks." This marks a tactical shift from his earlier refusal to contemplate more time. Intermediaries told the Financial Times that the two sides are "moving closer to an agreement" that would also set a framework for renewed negotiations over Tehran's nuclear program and sanctions relief.
A fragile military backdrop complicates the narrative. Al Jazeera reported fresh United States "self-defense strikes" on Iranian military sites near the Strait of Hormuz on the same days the ceasefire technically stayed in force. CENTCOM spokesperson Tim Hawkins told the network the latest attacks targeted "missile launch locations and Iranian vessels attempting to deploy mines." He insisted that U.S. forces were "exercising restraint during the ongoing ceasefire."
The prospect of 60 more days without a full-scale escalation around the Strait of Hormuz – which carries a significant share of global energy shipments – has acted as a pressure valve. Markets had been bracing for a supply shock. On prediction platform Polymarket, a market titled "US x Iran ceasefire extended by…?" has drawn more than $210 million in trading volume since early April. That figure reflects intense speculation over the durability of the truce.
Equities have treated the extension as confirmation that the worst-case scenarios remain off the table for now. The S&P 500 notched an all-time closing high at 7,230.12 on May 1. It has since pushed toward 7,400, marking six straight weekly gains.
Key insight: The equity rally is pricing a benign outcome: no Strait of Hormuz blockade, no oil supply shock, and no recession impulse from a Middle East conflict. Each day without escalation reinforces the late-cycle risk bid.
The move is not purely macro. A Yahoo Finance segment framed the initial ceasefire shock in early April: the Dow gained 2.76 percent, the S&P 500 gained 2.64 percent, and the Nasdaq gained 3.5 percent on the day of the Pakistan-brokered truce. Relief swept across risk assets in a near-uniform pattern.
Bitcoin (BTC) jumped above $72,000 during the initial ceasefire announcement on April 8, gaining nearly 5 percent in 24 hours. Ethereum (ETH) climbed about 6 percent to $2,257. Traders priced out immediate war risk.
More recently Bitcoin has been trading above $75,000. Some forecasts project a move toward $80,000 by the end of May if current momentum holds.
Crypto.news reported in early May that with the S&P 500 at a record 7,400, Bitcoin and other large-cap tokens have been trading as "high-beta extensions of U.S. equities rather than as independent hedges." BTC-S&P correlations have climbed toward 0.7 to 0.9. That means a 1 percent move in the S&P 500 tends to produce a 0.7 to 0.9 percent move in Bitcoin in the same direction.
The correlation cuts both ways. If a breakdown in talks or a new strike triggers an equity selloff, Bitcoin would likely follow. Analysts warn that a reversal in the stock market could quickly spill over into digital assets, with a drop below $70,000 as a plausible first stop.
The ceasefire extension does not eliminate the risk of miscalculation. The self-defense strikes reported by Al Jazeera indicate that military activity continues. If either side escalates in the coming weeks, the Strait of Hormuz could become a chokepoint for energy shipments.
A disruption there would trigger a spike in oil prices and a flight from risk assets. Equities would sell off. Crypto, given its correlation with equities, would follow.
What this means: The market is currently discounting a path where diplomacy holds for 60 days. Any deviation – new strikes, diplomatic breakdown, or an oil supply disruption – would challenge the current risk appetite. The S&P 500 at 7,400 and Bitcoin near $75,000 both reflect this optimistic baseline.
The real catalyst will be the unified proposal Tehran is expected to deliver within the 60-day window. Until then, risk assets remain exposed to headline risk from the Strait of Hormuz.

The ceasefire extension is constructive. The better market read recognizes that the rally depends on diplomacy holding for 60 more days. Any breakdown would invert the correlation: equities would sell off, and crypto would follow.
