That could hurt the chances for a tightening of the Pacific Basin products market, a crucial hub for global demand. As recently as early May, refineries in South Korea, Japan, Singapore, Taiwan and Thailand were planning or considering run cuts ranging from below 5% to 10%. However, Energy Intelligence understands that a Taiwanese refiner that was planning to trim runs by 300,000 barrels per day only two weeks ago has since decided against the cuts. Trading sources say some other planned run cuts appear unlikely to materialize also. For some refiners, margins — aided by lower crude oil prices — have improved enough recently that cuts are no longer necessary. And with the peak US summer driving season underway — with its associated jump in gasoline demand — Asian gasoline cracks have begun to increase significantly, bolstering overall refining margins. Cracks measure the profitability of refining products from crude.
