Oil prices climb 4%

Oil prices climbed about 4% on Tuesday on signs of higher demand in Europe and China, rising tensions in the Middle East and as buyers emerged the day after prices collapsed to a four-year low on a decision by OPEC+ to boost output.

Brent futures rose $2.37, or 3.9%, to $62.60 a barrel at 11:12 am (1512 GMT). US West Texas Intermediate (WTI) crude gained $2.42, or 4.2%, to $59.55. OPEC+ decided over the weekend to speed up oil production hikes for a second consecutive month.

"After evaluating the latest OPEC+ move to accelerate the easing of supply cuts, market players are focusing on developments in trade and the possibility ... that trade deals will be reached," said Tamas Varga, an analyst at PVM, a brokerage and consulting firm that is part of TP ICAP.

Varga also pointed to the rise in geopolitical risk premium in the Middle East as Israel struck Iran-backed Houthi targets in Yemen as a retaliation for an assault on Ben Gurion airport. Prices also drew support after consumers in China increased spending during the May Day celebration and as market participants returned after the five-day holiday.
