Markets opened on a positive note following the announcement of a memorandum of understanding regarding the Strait of Hormuz, a critical chokepoint for global energy flows. The agreement signals reduced geopolitical tension in one of the world's most important shipping lanes, where roughly one-third of seaborne oil passes through daily.

Energy stocks led the rally. Oil prices pulled back from recent highs as investors reduced hedges against supply disruption. West Texas Intermediate crude futures retreated below $80 per barrel, while Brent crude eased from elevated levels. The reprieve reflects market confidence that the shipping corridor will remain open and stable.

Equity indices climbed on the back of energy sector strength and broader risk-on appetite. The S&P 500 and Nasdaq gained in early trading as investors shifted away from defensive positions. Financial stocks also advanced, benefiting from the reduced volatility premium that had been priced into markets during the period of heightened Strait of Hormuz tensions.

The move underscores how geopolitical risk directly moves commodity and equity markets. When shipping lanes face closure risk, energy costs spike across the economy, pressuring margins for airlines, manufacturers, and transportation companies. The MOU removes that uncertainty, at least temporarily.

Bond markets reflected the shift as well. Longer-dated Treasury yields edged higher as investors moved out of safe-haven positions and into riskier assets. The 10-year Treasury yield climbed modestly as demand for government debt cooled relative to equities.

Investors remain alert to any developments that could destabilize the agreement. The Strait of Hormuz has faced periodic tensions from regional actors, and geopolitical risk remains a permanent feature of energy markets. Any escalation would quickly reverse today's gains and send oil sharply higher.

Markets will monitor incoming economic data this week alongside corporate earnings reports. Inflation readings and employment figures could shift focus away from geopolitical developments, particularly if data suggests the Federal Reserve may adjust its rate-hiking timeline.

Watch WTI crude, the S&P 500, and Brent crude for signals on whether the Strait of Hormuz agreement holds and whether energy-driven market momentum persists into the week.
