India’s Mangalore Refinery and Petrochemicals Ltd (MRPL) has sold a March loading high sulphur gasoil cargo at 25 per cent higher premiums than a cargo sold earlier this month, setting a more-than-20-month high, industry sources said on Monday. With spot demand from Yemen expected to increase in March, premiums for high sulphur gasoil in the Middle East are continuing to climb to new highs as supply remains thin, they said. MRPL has sold 40,000 tonnes of 0.5 per cent sulphur gasoil for loading over March 28-30 to Vitol at a premium of about $2 a barrel to Middle East quotes.
