Asia-Pacific refiners have increased their intake of US light sweet WTI crude for November loading and could remain keen buyers in December, potentially limiting supply for Europe.
Asian refiners have bought around 1.3mn b/d of WTI loading in November, traders say, up from roughly 800,000 b/d loading in October, and surpassing average flows of 1.15mn b/d to the region this year. Arbitrage economics from the US to Asia are better than those to Europe at present, traders say. And firmer refining margins for naphtha-rich crudes in Asia-Pacific could prompt refiners to maintain high purchases of WTI in December. Asian buyers tend to seek WTI around two weeks before European refiners owing to the longer shipping times, affecting availability of the grade in Europe.
European interest in November-loading WTI has been limited by refinery maintenance, exacerbated by an abundance of cheap light sweet crude in the region following the sudden restart of Libyan crude exports in October. The rebound in Libyan supply after a period of disruption pressured differentials for competing light sweet grades from the North Sea and Mediterranean regions. North Sea Forties and Ekofisk and Algerian Saharan Blend fell to their lowest in at least two months against North Sea Dated in mid-October.
At the same time, delivered WTI has been supported by high freight rates. Shipping costs to take an Aframax from the US Gulf coast to Europe were 62pc higher on average in October than in September, narrowing WTI's discount to North Sea light sweet crudes. Abundant and affordable WTI has tended to act as a cap on light sweet crude prices in the region. But the higher freight costs have meant that WTI has been one of the more expensive crudes in the North Sea Dated basket. WTI was at parity to light sweet Oseberg in early October, up from a discount of around $1/bl a month earlier. WTI has set the benchmark as the lowest-priced crude only six times in the past two months, compared with 26 occasions over the same period last year.
But European demand for crude is expected to rebound in December, as regional refineries ramp up following autumn maintenance. Ekofisk has already added around 60¢/bl relative to WTI since mid-October, briefly moving from a discount to a premium to the US grade over 25-29 October. Any WTI supply tightness in the final weeks of the year, and continued firm demand in Asia, could limit WTI flows to Europe and support light sweet crude prices.
Arbitrage effects
For some Asia-Pacific refiners, a workable WTI arbitrage has helped pressure the price of alternative supplies. Indian refiner IOC opted to buy two cargoes of WTI in a tender which closed on 17 October instead of the west African crude it typically favours. The refiner bought a cargo of WTI each from US-based Occidental Petroleum and Japanese trading company Mitsui for delivery in December and January to the western port of Vadinar and eastern port of Paradip, market participants say. Lacklustre interest from Indian and European buyers, and plentiful light sweet crude supply, have since combined to pressure some Nigerian crude differentials, pushing them down by 20¢-$1.15/bl against North Sea Dated in October.
This has helped reinvigorate demand and clear more November shipments on the eve of the December-loading cycle. IOC subsequently bought a shipment each of Nigerian Agbami from Chevron and Angolan Nemba from an undisclosed seller in a tender which closed on 24 October. But up to a dozen November-loading Nigerian cargoes remained unsold as of 29 October, according to traders.
