MELBOURNE (Reuters) – Oil prices fell in early trade on Wednesday after industry data showed inventories unexpectedly rose last week as a deep freeze in the southern states curbed demand from refineries that were forced to shut.

Crude stockpiles rose by 1 million barrels in the week to Feb. 19, the American Petroleum Institute (API) reported on Tuesday, against estimates for a draw of 5.2 million barrels in a Reuters poll.

API data showed refinery crude runs fell by 2.2 million bpd.

U.S. West Texas Intermediate (WTI) crude futures were down 55 cents or 0.9% at $61.12 a barrel at 0136 GMT, after slipping 3 cents on Tuesday.

futures fell 38 cents, or 0.6%, to $64.99 a barrel, erasing Tuesday’s 13 cents gain.

Investors will be awaiting confirmation from the U.S. Energy Information Administration later on Wednesday that crude inventories rose last week, despite the hit to shale oil production amid the unprecedented icy spell in the U.S. south.

“The key question is how quickly does U.S. oil supply recover. It looks like supply will recover faster than refineries, and supply is going to outpace demand in the next few weeks. That will give negative weight to the market,” Commonwealth Bank analyst Vivek Dhar said.

The price retreat is being seen as a pause following a rally of more than 26% to 13-month highs in both Brent and WTI since the start of the year.

Prices have jumped due to the U.S. supply disruption and supply discipline by the Organization of the Petroleum Exporting Countries and allies, together called OPEC+, led by an extra 1 million bpd cut by Saudi Arabia.

At the same time stimulus spending to boost growth, investors rotating into commodities, and hopes that the rollout of vaccinations could lead to an easing of pandemic restrictions are all buoying oil prices.
