Oil prices were steady today as investors questioned the effectiveness of a US-led release of oil from strategic reserves and turned their focus to how producers will respond.

Brent crude futures were down six cents at $82.25 a barrel in early afternoon trade after jumping by 3.3% yesterday.

US West Texas Intermediate (WTI) crude futures rose five cents, or 0.1%, to $78.55 after a 2.3% gain the previous day.

The US said it would release millions of barrels of oil from strategic reserves in coordination with China, India, South Korea, Japan and Britain to try to cool prices after OPEC+ ignored calls to pump more.

Japan will release "a few hundred thousand kilolitres" of oil from its national reserve, but timing has not been decided, its industry minister Koichi Hagiuda said today.

Analysts said the effect on prices was likely to be short-lived after years of declining investment and a strong global recovery from the Covid-19 pandemic.

The coordinated release could add about 70 million to 80 million barrels of crude supply, smaller than the more than 100 million barrels the market has been pricing in, analysts at Goldman Sachs said.

"On our pricing model, such a release would be worth less than $2 a barrel, significantly less than the $8 a barrel sell-off that occurred since late October," the bank said in a note with the title "a drop in the ocean".

Attention has now switched to how the Organization of the Petroleum Exporting Countries (OPEC), Russia and their allies, together known as OPEC+, will react to the joint reserve release when they meet on December 2 to discuss policy.

Meanwhile, US crude and gasoline stocks rose last week while distillate inventories fell, market sources said, citing American Petroleum Institute figures.

Crude stocks rose by 2.3 million barrels for the week ended November 19 compared to analyst expectations of a decline of about 500,000 barrels.
