Stocks traded higher for a second consecutive week as de-escalation triggered the strongest single day rally in a year. The S&P 500 gained +3.7%, with the Nasdaq and the Russell 2000 both returning +4.3%.
Most of the rally occurred on Wednesday after the announcement of a two-week ceasefire contingent on Iran reopening the Strait of Hormuz. Oil plunged -11%, the VIX dropped below 20, and international stocks rose as energy-importing nations benefited from the oil reversal. Industrials were the top-performing sector, gaining +5%, with broad strength across most sectors excluding energy.
Treasury yields fell modestly, and corporate bonds outperformed as credit spreads tightened to late January levels. However, the ceasefire was already being tested late in the week, with the market closely monitoring this weekend’s talks.
Key Takeaways
The U.S. and Iran agreed to a two-week ceasefire, triggering a relief rally.
Late Tuesday, the White House announced an agreement contingent on Iran reopening the Strait of Hormuz, less than two hours before a stated deadline to launch strikes on Iranian infrastructure.
Markets reacted decisively Wednesday: the S&P 500 surged +2.5%, its best single-day gain in a year, the Dow jumped +2.9%, the Russell 2000 gained +3.0%, and international equities rallied +3.5%. Unlike prior headlines, this was an actual agreement confirmed by both sides, with talks scheduled for this weekend.
Implication: The ceasefire is meaningful, but its durability was tested within hours. Israel launched strikes across Lebanon, Iran accused the U.S. of violating three conditions, and the Strait remained effectively closed Thursday morning. This weekend’s talks will determine whether the agreement marks a turning point.
Oil plunged -16% on Wednesday, its largest single-day decline since April 2020, as the market priced in a Hormuz reopening.
WTI fell from $112 to around $94, erasing weeks of the war-driven rally that had pushed oil up over +65% YTD. The decline triggered immediate secondary effects: airline stocks surged, and the odds of a rate cut increased as inflation expectations eased.
However, the physical reopening remains uncertain. As of Thursday morning, the Strait was still effectively closed, and oil was moving back toward $100.
Implication: Oil is the transmission mechanism through which the conflict reaches inflation, the Fed, consumers, and corporate profits. Wednesday’s decline showed how quickly the geopolitical premium can unwind, with the market watching for actual follow-through.
Credit spreads tightened and volatility declined, confirming the risk-appetite shift across asset classes.
High-yield spreads compressed during Wednesday’s ceasefire rally and are now the lowest since late January after tightening nearly -0.50% over the past two weeks. Credit spread tightening is an indication the market is starting to price in less stress.
The VIX fell to 21, its first close below 22 since late February, after touching 28 intraday Tuesday before the ceasefire was announced.
Implication: Credit and volatility are the market’s most reliable stress indicators, and both confirmed the equity rally as broad-based rather than speculative.
Treasury yields barely moved despite the ceasefire rally.
The 10-year yield fell just -0.03% to 4.28%, a muted response given the magnitude of the oil crash and equity rally. The bond market’s reaction reflects the Fed’s policy forecast. Seven of nineteen Fed members forecast zero cuts in 2026, and the Fed’s March minutes, released this week, reaffirmed its patient approach.
Implication: The bond market’s restraint suggests it is waiting for confirmation that the ceasefire will meaningfully improve the inflation and growth outlook.
Next week unofficially kicks off Q1 earnings season, with the big Wall Street banks reporting.
The focus will extend beyond the usual revenue and earnings beats to management commentary on the conflict’s impacts, from energy costs and supply chain disruptions to consumer demand and forward estimates.
Implication: Earnings calls will provide the first corporate read on how the energy shock is flowing through margins, pricing, and demand. Forward guidance and tone may matter more than the headline numbers this quarter.
