Shares of energy companies rose slightly, but did not track a historic spike in oil prices.
Oil futures jumped 12% to $90.90 a barrel in New York due to fears that the Strait of Hormuz, a key shipping lane for global oil supplies, would remain effectively closed for an extended period.
President Trump said U.S. attacks would not relent until an unconditional surrender from Iran.
The Trump administration said it had worked out a plan to insure ships in the Strait of Hormuz against war risk for up to $20 billion.
The SPDR Select Sector Energy exchange-traded fund, which tracks the energy industry group of the S&P 500, saw modest gains for the week, but is up about 23% for the year to date.
Investors do not anticipate the spike in oil futures to last long enough for major oil producers to capitalize on it.
