Oil slipped on Thursday on worries about rising US crude inventories and concerns about more rate hikes in Europe potentially hitting growth, paring this week's gains on signs of a strong economic rebound in China.
Brent crude futures fell 13 cents, or 0.15%, to $84.18 a barrel at 0715 GMT, while US West Texas Intermediate (WTI) crude futures were down 17 cents, or 0.2%, at $77.52 a barrel, Reuters reported.
Both contracts rose about 1% in the previous session after data showed manufacturing activity in China in February grew at the fastest pace in more than a decade, adding to evidence of an economic rebound in the world's second largest economy after the removal of strict COVID-19 curbs.
However, a tenth consecutive week of crude stock builds in the United States pressured the market.
US crude inventories rose by 1.2 million barrels in the week ending Feb. 24 to 480.2 million barrels, their highest level since May 2021, the Energy Information Administration reported.
Analysts polled by Reuters had expected a 500,000-barrel rise.
Record exports of US crude oil, however, kept the build smaller than in recent weeks, with shipments rising to 5.6 million barrels per day (bpd) last week, according to the EIA.
Oil was also hit by looming uncertainty on the overall global demand outlook, keeping prices "largely unchanged," said Serena Huang, head of APAC analysis at analytics firm Vortexa.
Expectations of rate hikes by the European Central Bank (ECB) are growing after inflation in Germany, Europe's largest economy, rose more than expected in February, with food and energy prices increasing despite relief measures.
This comes after France and Spain, also key economies in Europe, posted unexpected gains in inflation.
In the US, manufacturing contracted for a fourth straight month in February, though there were signs that factory activity was starting to stabilize, with a measure of new orders pulling back from a more than 2-1/2-year low.
"German inflation raised worries that the ECB will have to be more aggressive with its tightening cycle. The US data shows the economy is still slowing down but some parts are improving," said Edward Moya, senior market analyst at OANDA, in a note.
"Oil looks like it will stay stuck in a trading range, but the risks are clearly to the upside. Some traders might be waiting until we get a better sense of what will be the peak rate after next Friday's nonfarm payroll report."
Meanwhile, crude oil processed by Indian refiners reached record levels in January, provisional government data on Wednesday showed, as the country boosted imports of Russian barrels that Western countries shunned.
Refinery throughput in the world's third-largest oil importer and consumer reached 5.39 million barrels per day for January, the highest since Reuters records going back to 2009.
