HONG KONG - 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.
The US president's announcement was a direct response to Tehran's demand for US war reparations as a precondition to any resolution of the crisis.
Trump's remarks came a day after he said he was "low-keying" his approach to the conflict, suggesting he was prepared to let economic pressure mount in place of further military strikes.
However, the latest back and forth risks putting a quick agreement further out of reach, and on Monday both main crude contracts jumped around five percent. They extended the gains on Tuesday.
"In the absence of any positive headlines on negotiations to reopen the strait, pressure on oil prices has been upward," wrote Jason Wong at BNZ.
And Stephen Innes, global strategist at Quintex Intel, said: "In effect, both sides are trying to weaponise the oil barrel without firing another shot. Washington is trying to choke Iran's ability to get its crude out, while Tehran is squeezing the artery through which everybody else's crude gets through.
"It is quite the game of chicken."
