SINGAPORE, March 18 (Reuters) - Asia's fuel oil viscosity spreads narrowed on Monday, prompted by heavy buying of the 380-centistoke (cst) fuel oil during the physical trading window. The front-month April viscosity narrowed by $2.00 to $9.75 a tonne by the Asian close, Reuters data showed. Viscosity is the difference between the outright prices of 180-cst and 380-cst fuel oil, and acts as an indication of the blendstock balance in the market. Oil major BP picked up 200,000 tonnes of 380-cst fuel oil, while PetroChina bought 60,000 tonnes of the higher viscosity grade. BP also sold 60,000 tonnes of 180-cst, while PetroChina offloaded one 20,000-tonne cargo of the lower viscosity fuel oil.
Fundamentals point to an easing market next month, as Western arbitrage inflows in April are expected to be higher than March at around 4.7 million tonnes. Demand for straight-run fuel oil by teapot refiners in China has also slowed due to weak margins of gasoline and diesel. By the Asian close, the prompt April/May intermonth swaps inched up 13 cents to a backwardation of $2.63 a tonne, according to Reuters data.
