A U.S.-Iran memorandum of understanding has overtaken the Federal Reserve as the primary driver of global markets, redirecting attention from monetary policy to geopolitical risk.
The Federal Reserve held its benchmark rate at 3.5% to 3.75% on Wednesday, but a U.S.-Iran memorandum of understanding has supplanted monetary policy as the dominant force driving global markets, traders and strategists said.
"The market's center of gravity has moved from the Fed statement to the negotiating table," said Chris Rupkey, chief economist at FWDBONDS LLC. "One thing is certain and that is the Federal Reserve will definitely not cut interest rates this year."
The S&P 500 slid 1.2% on Wednesday after Chair Kevin Warsh's first press conference, with the Nasdaq composite losing 1.3% and the Dow Jones Industrial Average falling 1%. The VIX volatility index spiked 13% as investors digested a more hawkish tone than expected. The 10-year U.S. Treasury note sold off, with its yield rising about 5 basis points to 4.498%.
The MoU represents the most significant diplomatic development since the U.S.-Iran ceasefire, with direct implications for energy prices, inflation expectations, and the Fed's policy trajectory. Brent crude oil traded at $79.13 a barrel, below the $80 threshold that had fueled inflation concerns. If the agreement holds and oil prices decline further, the inflationary pressure that has kept the Fed on hold could ease, potentially reopening the door for rate cuts later this year.
Warsh's First Meeting Sets Hawkish Tone
New Fed Chair Kevin Warsh used his first meeting to signal a departure from his predecessor's approach. The FOMC statement was roughly half the length of April's, dropping the "easing bias" language that had signaled a future inclination to cut rates. Warsh announced five task forces examining the Fed's communication, balance sheet, data sources, inflation framework, and productivity and jobs — with recommendations expected by the end of 2026.
Of the 18 policymakers who submitted projections, eight see the fed funds rate holding steady through year-end, nine see room to hike, and one sees room to cut. Warsh himself did not submit a forecast, declining to offer forward guidance. Traders have shifted expectations away from a cut and now anticipate the Fed's next move could be a rate hike, according to market pricing.
What the MoU Means for Markets
The shift in focus from the Fed to the MoU reflects a recognition that geopolitical developments may have more near-term influence on inflation than monetary policy. Consumer prices rose 4.2% in May from a year earlier, while the Fed's preferred PCE gauge stood at 3.8% in April — both well above the 2% target. Energy costs, driven by the Iran conflict, have been a primary contributor.
Consumer sentiment improved to 48.9 in June from 44.8 in May, with the University of Michigan survey citing relief at the gas pump. The national average for regular gasoline fell to $4.03 a gallon on June 17, down from $4.51 a month earlier. Hopes that a peace deal could be finalized by the end of this week drove oil prices to a three-month low, a dynamic that may give policymakers further reason to hold off on rate moves while they assess how negotiations play out.
"The bond market needs more convincing that inflation isn't going to be embedded in the economy," said John Mousseau, chief investment officer at Cumberland Advisors. Higher yields have significant implications: the 30-year fixed-rate mortgage, which tracks the 10-year Treasury, remains elevated, and the government's borrowing costs continue to rise — a cost ultimately borne by taxpayers.
