Oil higher

Singapore : U.S. oil prices hit their highest since 2015 again on Tuesday as speculators bet on further price rises amid OPEC-led production cuts and a dip in American drilling activity, though some warned the rally could run out of steam.

United States West Texas Intermediate (WTI) crude futures were at $62.24 a barrel at 0252 GMT - 51 cents, or 0.8 percent, above their last settlement.

They earlier marked a May-2015 high of $62.56 a barrel. Beyond that 2015-high, which was a short intra-day spike, Tuesday´s peak was the strongest level for WTI since December, 2014, at the start of the oil market slump.

Brent crude futures were at $68.22 a barrel, 44 cents, or 0.65 percent, above their last close. Brent touched $68.27 last week, its highest since May, 2015.
