The U.S. and Iran exchanged heavy airstrikes over the weekend, marking a sharp escalation in the scale and reach of attacks which prompted Trump to revive the U.S. blockade on Iranian ports, raising concerns about the path forward for peace negotiations. Crude prices CLc1 surged, settling up 9.4%, fueling worries that strained supply and upward energy price pressures could broaden into long-term, systemic inflation. Warsh is due to sit for his first semiannual testimony before Congress on Tuesday and Wednesday, during which the new head of the central bank will be questioned regarding the inflationary effects of the U.S.-Iran war and the Fed's likely course of action. Markets are pricing in at least one 25-basis-point rate hike by year-end, according to LSEG data. To that end, the Labor Department is expected to release its consumer (CPI) and producer (PPI) price indexes this week, which will give markets and the Fed a glimpse at the extent to which the on-again-off-again U.S.-Iran war affected price growth in June.

Major financial firms Bank of America BAC.N, Citigroup C.N, Goldman Sachs GS.N, JPMorgan Chase JPM.N and Wells Fargo WFC.N were all slated to report quarterly results on Tuesday, marking the unofficial start of second-quarter earnings season. Analysts currently expect aggregate second-quarter S&P 500 earnings growth of 23.7% year on year, up from the 19.2% estimates as of April 1, according to LSEG. U.S. stocks fell on Monday after President Donald Trump announced that he would reinstate a blockade on Iranian ports in the latest escalation of U.S.-Iran hostilities that sent oil prices jumping and dampened risk appetite. Investors stared down what promised to be an eventful week packed with earnings, economic data and congressional testimony from U.S. Federal Reserve Chair Kevin Warsh. Among the three major U.S. stock indexes, the tech-laden Nasdaq led the losses, followed by the S&P 500. The Dow's drop was cushioned by rising energy stocks .SPNY, which were boosted by spiking crude prices due to restricted traffic through the Strait of Hormuz.
