Oil retreated near $52 a barrel as investors assessed surging U.S. production against output curbs pledged by some of the world\u2019s top suppliers. Futures lost as much as 1 percent in New York, trimming gains of 3.6 percent over the past two sessions. American crude output jumped to a record last week, countering signs of shrinking supplies from the OPEC+ coalition. Saudi Arabia reduced shipments to U.S. refiners by a third last week, while Russia\u2019s deputy energy minister said the country will meet its target for curbing production by April. While crude has bounced over 20 percent from last year\u2019s low on Christmas Eve, it\u2019s still below a four-year peak in October. Whether prices will remain in a bull market largely depends on effectiveness of the curbs planned by the Organization of Petroleum Exporting Countries and its allies in the face of booming U.S. supply. At the same time, concerns persist in global markets over a slowdown in growth, hurting appetite for risk assets. READ ALSO |\u00a0Good news for taxpayers!

In Saudi Arabia, the kingdom has slashed its crude shipments to refiners in the U.S. by 32 percent to 684,000 barrels a day for the week that ended on Jan. 11, after exporting more than 1 million barrels a day in the previous week, according to the preliminary data from the EIA.
