The US-Iran peace deal announced June 14 triggered the largest one-day unwind of geopolitical risk premium since the conflict began in February.
The dollar weakened to a one-week low and oil tumbled more than 4% after the US and Iran agreed to a peace deal, ending nearly four months of conflict that had closed the Strait of Hormuz and reshaped global energy markets.
"Markets have been waiting for this news for months, and the relief is already showing, with oil sliding and risk assets catching a bid," said Josh Gilbert, lead analyst for APAC at eToro.
The dollar index fell 0.32% to 99.483, while the euro held near a one-week high at $1.15725 after the European Central Bank delivered its first rate hike in three years. US crude futures for July delivery dropped 4.77% to $80.83 a barrel, and Brent for August settled 4% lower at $83.77. Asian equities surged — South Korea's Kospi jumped 5.1%, Japan's Nikkei 225 climbed 3.6% — as investors rotated out of safe havens.
The agreement, which remains unsigned until June 19, reopens the Strait of Hormuz and lifts the US naval blockade, potentially restoring oil flows to 60% to 70% of pre-war levels. That shift could ease inflation pressures just as the Federal Reserve prepares for its rate-setting meeting next week, where markets see a greater than 50% chance of a hike by year-end.
Gold Holds Bid as Skepticism Lingers
Not all assets behaved as a clean risk-on signal would predict. Spot gold rose almost 2% to $4,302.19 an ounce, defying the typical inverse relationship with risk appetite. "Gold is the interesting outlier here," said Billy Leung, investment strategist at Global X ETFs. "In a clean risk-on trade, gold should be selling off as the geopolitical premium unwinds, but it is holding bid around $4,300, which tells you the market is not fully trusting the deal yet."
The 10-year Treasury yield fell 5 basis points to 4.423%, suggesting investors were dialing back inflation expectations on cheaper energy rather than fleeing to safety. "The most immediate implication is a repricing of the inflation risk premium that markets have been carrying since the Strait closed," Leung said.
Implementation Risk Caps the Rally
The deal's fragility limits how far the risk-on trade can run. The memorandum of understanding remains unsigned, and leaked terms that appeared to favor Iran drew criticism from President Donald Trump, who called the reports inaccurate. On Polymarket, the contract asking whether the Iranian regime will fall before 2027 still prices No at 89.5%, with volume approaching $20.1 million.
Commonwealth Bank of Australia analysts cautioned that damage to refining infrastructure, the presence of sea mines and uncertainty over tanker traffic could slow the return to normal operations. Vivek Dhar, head of commodities and sustainability research at CBA, expects Brent to fall to around $80 a barrel by year-end assuming the Strait remains open. "The deal isn't actually signed until June 19th, the details are still thin, and this conflict has shown more than once that headlines can turn on a dime," Gilbert said.
The last time a major Middle East conflict ended with a negotiated settlement — the 2020 Abraham Accords — oil prices fell 8% in the first week and the dollar weakened 1.5% over the following month as the risk premium unwound gradually rather than all at once.
For investors, the biggest implication may be what cheaper energy means for central bank policy. Lower oil prices ease pressure on households and businesses while reducing the risk of a broader inflation resurgence. "The broader read for global investors is constructive," Gilbert said. "A sustained decline in oil prices takes some weight off central banks."
