HONG KONG, China (AFP)—Oil prices extended hefty gains Tuesday as hopes for a reopening of the Strait of Hormuz fade, fanning fresh inflation fears and ramping up bets on at least one US interest rate hike this year.

Crude has surged around 10 percent over the past week, with the United States and Iran appearing no closer to a deal on the crucial waterway despite upbeat comments from the White House earlier in the month.

In the latest blow, Donald Trump said Monday he would seek conflict compensation from Iran as part of any peace negotiations, citing attacks and killings stretching back decades allegedly backed or perpetrated by Tehran.
