What this means for investors

Major indexes rallied on news of a two-week ceasefire in the Iran conflict. WTI Crude fell 15% to $96 a barrel after parties agreed to reopen the Strait of Hormuz for the first time since the war began over five weeks ago. Falling oil prices eased energy-driven inflation fears, and markets began to reassess the possibility of a rate cut this year.

The mood on Wall Street remained cautious, as this is only the start of the necessary negotiations that could drive a more permanent resolution. Even then, it will take time for the energy disruptions to normalize. For investors, it will be important to monitor developments in the Strait of Hormuz in the short term. Upcoming earnings reports and inflation data will provide further insight into the medium- and long-term impact of the war.
