Geopolitical De-escalation Drove Risk-On Sentiment

Equity markets rallied this week as tensions in the Middle East appeared to cool. Iran announced that the Strait of Hormuz was fully open to commercial traffic, following a ceasefire between Israel and Lebanon. Friday's session saw the Dow climb more than 1,000 points, and the S&P 500 crossed the 7,100 mark for the first time.

Reduced conflict risk generally lowers the premium embedded in oil and other risk assets. Investors appeared to rotate back toward cyclical sectors and growth names, while safe-haven demand for Treasurys eased slightly. Conditions remain fluid, and geopolitical developments can shift quickly.

Sharp Reversal in Energy and Dollar

WTI crude oil fell roughly 11% on the week, a notable reset after recent highs tied to conflict fears. The U.S. dollar index slipped to a seven-week low as the flight-to-safety bid unwound. Lower energy prices can filter through to headline inflation readings, consumer spending, and corporate input costs over time.

A softer dollar often supports multinational earnings and can ease financial conditions for overseas borrowers holding dollar-denominated debt. How durable this reversal proves will depend on follow-through in diplomacy and underlying supply dynamics.

Nasdaq's Historic Streak and Rate-Cut Repricing

The Nasdaq Composite notched its 13th consecutive advance, the longest stretch since 1992. Large-cap technology leadership was supported by falling yields and renewed optimism around earnings. The 10-year Treasury yield drifted lower to 4.26%, reflecting expectations that easing oil prices may reduce pressure on the Federal Reserve.

Streaks of this length are uncommon, and history suggests momentum can fade without warning. Broader participation across sectors would help confirm the rally's durability.

Looking Ahead

Several items are worth watching in the week ahead. First-quarter earnings reports accelerate, with results from large banks, industrial firms, and technology leaders likely to shape sector sentiment. Housing and durable goods data will offer fresh read-throughs on the consumer and business investment. Any shift in Middle East headlines could quickly change the tone for oil and equities. These are observations, not forecasts, and markets often move in ways that surprise even seasoned participants.

Past performance is not indicative of future results. All investing involves risk, including the potential loss of principal.
