London: Oil declined after the biggest two-day increase in more than a month as prices fluctuated following a fall into a bear market this week.

Futures dropped as much as 1.2 per cent in New York after rising 6.1 per cent the previous two sessions, rebounding from the lowest closing price since April. Baker Hughes Inc. reports drill rig data Friday, which will signal if US producers are continuing to boost activity. Government figures Wednesday showed gasoline inventories fell, while crude stockpiles unexpectedly rose. Both are at the highest seasonal level in at least two decades.

Oil is fluctuating after tumbling more than 20 per cent into a bear market and closing below $40 a barrel on Tuesday for the first time in almost four months. Citigroup Inc. and Bank of America Merrill Lynch predicted the slump would be short-lived, while Societe Generale SA said the price correction would be limited due to a better balance between supply and demand.

“One of the things that triggered the price retreat is the consistent gains in rig count we’ve had, so we’ll want to look at what’s happening with rigs in today’s data,” Michael Hsueh, strategist at Deutsche Bank AG in London, said by email. “If the rig count addition goes above five per week and stays there, that rings an alarm bell for the production outlook in 2017.”

West Texas Intermediate for September delivery lost as much as 49 cents to $41.44 a barrel on the New York Mercantile Exchange and was at $41.88 at 1:16pm. London time. The contract rose $1.10 to close at $41.93 on Thursday, capping the biggest two-day gain since June 29. Prices are up 0.6 per cent this week. Total volume traded was about 20 per cent below the 100-day average.

US stockpiles

Brent for October settlement slid as much as 54 cents, or 1.2 per cent, to $43.75 a barrel on the London-based ICE Futures Europe exchange. The contract on Thursday added $1.19 to $44.29. Front-month prices are up 3.8 per cent this week. The global benchmark traded at a premium of $1.61 to WTI for October.
