Global equity markets staged one of their sharpest relief rallies of the year on Monday after the United States and Iran announced a tentative framework to end their six-month war, sending Brent crude sliding below $78 a barrel and pulling the Nasdaq up more than 2 percent in early European trading. The S&P 500 followed, with futures pointing to a 1.4 percent gain at the Wall Street open, while the Stoxx Europe 600 added 1.1 percent as energy and defense stocks gave back some of the premiums built up since the Strait of Hormuz was first threatened in January.
The framework, confirmed by both capitals shortly after midnight GMT, would see Iran cap its nuclear enrichment program, hand over more than 60 percent of its enriched uranium stockpile, and accept intrusive inspections in exchange for broad sanctions relief and the unfreezing of roughly $30 billion in central bank assets. Critically for traders, the deal also reopens the Strait of Hormuz to commercial shipping under international naval escort, removing what had been a roughly $14 a barrel geopolitical risk premium that has been baked into the price of oil for the better part of five months.
Brent fell as much as 7.8 percent to $77.40 a barrel in early London trading, its lowest level since November, before stabilizing near $78.50. West Texas Intermediate slid a similar amount, slipping under $74. The move is the most violent single-session drop in oil since the early days of the pandemic and reverses, in a single day, roughly a third of the gains the energy complex has accumulated since the conflict began.
Equity traders moved quickly to reposition. Airline and cruise stocks, hammered for months by fuel costs, surged: the NYSE Arca Airline Index jumped 6.4 percent in premarket trading, with American Airlines, Delta, and Carnival each gaining more than 5 percent. Container shipping groups Maersk and Hapag-Lloyd rallied on the prospect of normalized Hormuz traffic. On the other side of the ledger, energy majors including ExxonMobil and Chevron lost more than 3 percent, and oilfield services names such as Halliburton and Schlumberger slid harder as the squeeze on upstream profitability eased.
Bond markets signaled a quieter but equally significant shift. The yield on the 10-year US Treasury note dipped three basis points to 4.21 percent as investors marked down the odds of an energy-driven inflation pulse and pushed out the expected timing of any further Federal Reserve tightening. Futures contracts now imply a 78 percent probability that the Fed holds rates at its July meeting, up from 64 percent on Friday, with traders pricing in a first cut in December rather than September.
Relief is not the same as resolution
Investors were quick to caution that the framework is not yet a final agreement. Several core issues, including the precise sequencing of sanctions relief and the fate of Iran’s stockpile of advanced centrifuges, remain unresolved. A signing ceremony is being planned for Geneva later this month, but negotiators acknowledged that the final text could still take weeks to finalize and that either side could walk away from the table if domestic politics shift.
That uncertainty was visible in currency markets, where the US dollar held steady against the euro but slipped against emerging market currencies that have been pressured by the oil shock. The Indian rupee, Turkish lira, and South African rand each gained more than half a percent, reflecting both the immediate drop in import costs and the prospect of steadier capital flows.
Central banks reset their calendars
For central bankers, the deal does not change the underlying inflation problem already in the pipeline, but it does remove the tail risk that has been preventing them from moving in either direction. With oil now stabilizing in the high $70s, the European Central Bank and the Bank of England have a clearer path to continue holding rates steady while monitoring services inflation, while the Federal Reserve retains the optionality to begin cutting later this year if labor market data continue to soften.
Commodity analysts at several major banks moved quickly to revise their year-end forecasts, with Brent now expected to average $82 a barrel in the fourth quarter, down from a previous consensus of $94. That revision alone could shave roughly 0.3 percentage points off headline inflation in the United States and Europe by year-end, giving policymakers more room to focus on growth.
