U.S. stocks rallied into Monday’s closing bell as easing oil prices and tentative signs of de-escalation in the Iran conflict helped investors look past early fears as the U.S. started to blockade Iranian ports. The Dow Jones Industrial Average rose 300.69 points, or 0.63%, to 48,217.3, while the S&P 500 gained 69.23 points, or 1.02%, to 6,886.12, and the Nasdaq Composite advanced 280.84 points, or 1.23%, to 23,183.7. Crude oil settled at 98.02, up 1.45, or 1.50%, after trading above $100 earlier in the session, while the CBOE Volatility Index edged down 0.02 to 19.21.

The day’s central driver was energy. Oil surged as traders reacted to escalating war risk tied to Iran and the possibility of further disruption around the Strait of Hormuz, then gave back part of those gains as immediate panic cooled. That reversal helped steady broader risk appetite and allowed equities to recover into the afternoon, particularly in growth and cyclical shares.

The market’s tone suggested investors were not dismissing the geopolitical threat, but were recalibrating around the view that the worst-case supply shock had not yet materialized. The relatively muted close in the VIX reinforced that interpretation. Even with crude finishing solidly higher, a retreat from the session’s highs reduced some of the inflation and margin pressure fears that had weighed on stocks earlier in the day.

Attention is now shifting toward earnings, with large banks set to open reporting season. Citigroup enters the week with heightened expectations after a prolonged restructuring effort under Chief Executive Jane Fraser. The bank is framed as approaching a critical test of whether its turnaround has translated into durable operating leverage and stronger profitability.

JPMorgan, meanwhile, is expected to post another solid quarter, but investors will be listening closely to Jamie Dimon’s comments on oil, credit quality and macro risk. The AInvest preview on JPMorgan emphasized Dimon’s caution around energy-driven inflation and the potential for broader stress if geopolitical tensions persist.

That leaves the market balancing two narratives at once: a geopolitical oil shock that has not fully passed, and an earnings season that could still validate the resilience of corporate America. Financials will be especially important because they offer an early read on credit conditions, consumer health and executive confidence.
