Oil dropped more than 3% after Trump announced a deal to reopen the Strait of Hormuz. The dollar weakened. Traders priced lower energy costs and a risk-on shift.
The US and Iran agreed to reopen the Strait of Hormuz, ending a four-month war that killed thousands and disrupted global energy flows. President Donald Trump announced the deal on social media Sunday, authorizing the removal of the US naval blockade. Iranian state media framed the agreement as a US capitulation.
Oil prices dropped sharply. Brent crude fell more than 3% toward $84 a barrel, after closing last week at the lowest in more than three months. West Texas Intermediate traded near $81. The dollar slipped against Group-of-10 peers in early Asia trading. The risk-sensitive Australian dollar led gains, rising about 0.5%. The euro strengthened 0.3% against the greenback.
Neither side released the full text of the deal. Iran's Deputy Foreign Minister Kazem Gharibabadi said on state television that the memorandum of understanding will be published after the official signing, scheduled for June 19. The broad terms had circulated for days. The US and Iran will end their competing blockades of the strait, one of the world's busiest waterways. They agreed not to attack each other and to start negotiations on Iran's nuclear program. Iran would get relief from sanctions targeting its overseas oil sales.
Both sides claimed victory. Deep distrust remains. Grave questions hang over their ability to reach a broader deal. The view from Israel is unclear. Prime Minister Benjamin Netanyahu's government jeopardized a signing at the last minute with new attacks on Lebanon. Trump may face severe blowback from Iran hawks at home. They worry he is punting on the issues that were the reasons he began the war in the first place: Iran's nuclear capability and its ballistic-missile program.
The financial incentives Iran will receive are also unclear. A senior US official who spoke to reporters on Friday said the two sides were circling an agreement where Iran would earn economic rewards each time it met a set of US demands. Iran has also demanded access to billions of dollars in funds frozen in overseas bank accounts, as well as long-term relief from sanctions.
For traders, the immediate read is straightforward. The risk premium baked into crude prices since January is unwinding. Brent had held above $90 for much of the war, pricing in a sustained disruption to the roughly 20 million barrels per day that transit the strait. The deal removes that floor.
The better market read is more layered. The dollar's slip and the Aussie's rally suggest the market is pricing a broader risk-on shift: lower energy costs, lower inflation expectations, and a repricing of Fed rate-cut odds. That trade will live or die on the nuclear talks. If negotiations stall, the sanctions relief that underpins the oil-price drop never materializes, and the crude selloff reverses. If talks advance, the next leg lower in oil could take Brent toward $75, where pre-war supply-demand balances sat.
What to track: the June 19 signing date, the text of the memorandum, and any statement from Israel's government. A hawkish Israeli response would reintroduce geopolitical risk. A clean signing with no spoilers would confirm the risk-off in oil and the risk-on in currencies and equities.
