Oil stocks and oil-related currencies slammed by OPEC move

Oil prices, oil-related shares and oil-linked currencies all tumbled on Friday, in the wake of OPEC's decision to refrain from cutting output despite a huge oversupply.

U.S. markets were closed on Thursday for the Thanksgiving holiday, leaving the spotlight on the Organization of Petroleum Exporting Countries' meeting in Vienna where Saudi Arabia blocked calls from poorer cartel members to cut production to stem a slide in global prices.

Brent crude settled at a four-year closing low of $72.82 a barrel in Asian trading. Early Friday, Brent rebounded slightly to trade around $73 a barrel.

U.S. crude plunged 6.9 percent to $68.59. In early trading Friday, U.S. crude dipped to $69.31.

"In the short term, given market skepticism that recent price levels are low enough to substantially slow U.S. output growth, we expect price levels to drop below $70/bbl for Brent and even lower for WTI (U.S. crude)," Barclays analysts said in a note.

Japan's industrial output unexpectedly rose 0.2 percent in October, marking a second straight month of gains. Core consumer prices rose 2.9 percent in October, in line with forecasts, while the jobless rate fell and the availability of jobs edged higher last month.

The dollar rose about 0.3 percent against the yen to 118.08 yen, while the euro drifted down about 0.1 percent to $1.2452.

But the greenback made dramatic moves against the currencies of oil-rich countries. The dollar rallied to 6.9501 Norwegian crowns, a high not seen in over five years, and was last at 6.9442.

The U.S. dollar spiked to a one-week high against its Canadian counterpart at C1.1355, before steadying at C$1.1339 in Asia.
