- JPMorgan Chase (JPM) CEO Jamie Dimon warned in his annual shareholder letter that the war risks massive oil and commodity price shocks that could keep inflation "sticky."
- Secretary of War Pete Hegseth confirmed that Monday’s operations represent a significant escalation, with even more intense strikes planned for Tuesday.

Loud explosions rocked the Iranian city of Isfahan on Monday as the United States and Israel executed a coordinated wave of missile strikes. The operations targeted weapons depots and missile sites in the central province, which serves as a major industrial and military hub for the Iranian regime.
Secretary of War Pete Hegseth told reporters at the White House that Monday saw the highest volume of strikes since the start of the military campaign. Hegseth warned that the intensity of the bombardment would increase on Tuesday, framing the escalation as a final ultimatum for Iran to reopen the Strait of Hormuz.
Financial markets reacted sharply to the military developments and a stark warning from JPMorgan Chase (JPM) CEO Jamie Dimon. In his annual letter to shareholders, Dimon stated that the "war in Iran risks oil and commodity price shocks" that could derail global efforts to cool inflation.
Dimon noted that persistent inflation above the 2% target could force central banks to keep interest rates elevated for longer than anticipated. He cautioned that the reshaping of global supply chains due to the conflict could lead to a period of stagflation, characterized by rising prices and slowing growth.
The United Nations has expressed "deep concern" over the nature of the strikes, specifically the targeting of Iranian infrastructure. According to reports from Bloomberg, the UN warned that attacks on civilian-linked assets like power plants and bridges risk violating international humanitarian law and the UN Charter.
President Donald Trump has reportedly set an 8:00 PM Tuesday deadline for Iran to reach a deal or face further destruction of its domestic energy grid. Market analysts suggest that any prolonged disruption to the Strait of Hormuz could push Brent crude and WTI prices significantly higher, further complicating the global economic outlook for the remainder of 2026.
