Geopolitical events dominated the first trading week of March 2026. The start of U.S. and Israeli military operations against Iran prompted a sharp rise in oil prices as Iran's military launched ballistic missile attacks against Persian Gulf nations and threatened shipping traffic through the strategic chokepoint of the Strait of Hormuz.
That escalation prompted marine insurers to cancel war risk coverage for oil container ships, which in turn, sharply reduced shipments of oil out of the Persian Gulf as shippers were unwilling to risk transiting the strait. The resulting new constraint on the 20% of global oil supply that is transported from the oil-rich nations of the Persian Gulf caused the global price of oil to jump over ten percent.
The increase in oil prices put central banks on notice to combat inflation. In the U.S., the prospects for additional interest rate cuts by the Federal Reserve during 2026 dimmed in response to the development. The CME Group's FedWatch Tool projects the Fed will delay an expected quarter point reduction in the Federal Funds Rate steady until 29 July (2026-Q3), six weeks later than what was anticipated a week earlier. The tool also projects another quarter point rate cut on 9 December (2026-Q4).
The effect on stock prices however was more muted. The S&P 500 (Index: SPX) declined 2.0% from its previous week's close to end the trading week at 6,740.02.
The latest update of the alternative futures chart shows the trajectory of the index is still within the redzone forecast range we introduced in the previous edition of the S&P 500 chaos series, but instead of being in the middle, it moved near the lower end of the range.
