US-Iran Provisional Ceasefire Sends Oil Prices Down 2 Percent as Markets React Cautiously

A provisional 60-day ceasefire agreement between the United States and Iran, aimed at resuming nuclear program talks, drove energy prices down approximately 2 percent on June 1, 2026, providing some relief to consumers and markets after months of elevated oil costs.

The ceasefire reduced market-implied volatility and sent government bond yields lower on both sides of the Atlantic. U.S. equity markets showed slight upward movement, while Asian markets, particularly Japan's Nikkei-225, outperformed.

Markets are now pricing in two rate hikes from the European Central Bank and one from the Federal Reserve before the end of the year. The Fed has held the federal funds rate at 3.5 to 3.75 percent, with future cuts appearing less certain following inflation data showing a 3.3 percent increase in the Consumer Price Index for the 12 months ending in March 2026.

Energy prices had surged 10.9 percent in March, largely driven by military conflict involving Iran that disrupted oil supplies through the Strait of Hormuz. The ceasefire, if it holds, could ease that pressure.

Inflation data for May in France, Germany, and Spain came in lower than anticipated, adding to cautious optimism in European markets. Market participants are watching for the release of Eurozone PMI data and U.S. nonfarm payroll figures later in the week.

The S&P 500's direction for June 1 was characterized by prediction markets as a near coin flip, with an implied probability of 47.5 percent for an upward close. Investors remain focused on upcoming ISM Manufacturing PMI data and potential geopolitical shifts regarding the Strait of Hormuz.

High gasoline prices and elevated interest rates continue to strain consumer budgets. Forecasts suggest modest-to-moderate economic growth through the remainder of 2026, with no immediate recession expected.
