Brent crude futures rose 63 cents, or 0.8%, to $84.81 a barrel at 0840 GMT, while U.S. West Texas Intermediate futures gained 68 cents, or 0.9%, to $80.42 a barrel, Reuters reported.

Data from China showed consumer inflation in March at its slowest pace since September 2021, suggesting demand weakness persists amid an uneven economic recovery, which spurred expectations Beijing may take steps to boost growth.

"China's March CPI is lower than expected, which may promote the Chinese government to further stimulate the economy," said Tina Teng, an analyst at CMC Markets.

Crude futures also climbed as the dollar eased on expectations that the U.S. Federal Reserve is getting closer to ending its rate hike cycle. A weaker greenback makes oil cheaper for those holding other currencies.

"With more central banks pausing rate hikes, such as the Reserve Bank of Australia, Bank of Korea ... the expectation for the Fed to further scale back its tightening policy has been strengthened," Teng added.

Signs of strong March fuel demand in India, the world's third-biggest oil consumer, also supported prices. Last month, fuel consumption jumped by 5% from a year earlier to a record 4.83 million barrels per day.

Oil futures have climbed more than 5% since the Organization of the Petroleum Exporting Countries (OPEC) and allies including Russia surprised the market last week with a new round of production cuts starting in May.

"The voluntary production cuts by some OPEC+ members should tighten the oil market further from May onwards and support oil prices," said UBS analyst Giovanni Staunovo.

On the U.S. supply front, industry data on U.S. crude stockpiles is due on Tuesday. Five analysts polled by Reuters estimated on average that crude inventories fell by about 1.3 million barrels in the week to April 7.

A U.S. inflation report to be released on Wednesday could help investors gauge the near-term trajectory for interest rates.
