HOUSTON, July 13 (Reuters) - Prices broadly rose on Monday, dealers said, after U.S. President Donald Trump said the United States was reinstating its blockade of Iranian shipping in the Gulf, reigniting concerns over energy shipments through the Strait of Hormuz.

Trump also said the U.S. would ensure the Strait of Hormuz stays open — for a fee — after the two sides exchanged more missile and drone attacks.

And in an interview with U.S. radio show host Hugh Hewitt, Trump said Iran would be hit hard Monday and Tuesday.

Meanwhile, U.S. oil refiners are expected to have about 200,000 barrels per day of capacity offline for the week ending July 17, increasing available refining capacity by 70,000 bpd, research company IIR Energy said on Monday.

Offline capacity is expected to decrease to 89,000 bpd in the week ending July 24.
