US Cash Crude-Coastal grades rise on strong export economics

HOUSTON, Nov 20 (Reuters) - Coastal grades edged higher on Thursday, dealers said, as the spread between West Texas Intermediate crude futures and global benchmark Brent widened, which typically makes U.S. grades more attractive to foreign buyers.

Offshore grade Mars Sour rose for the fourth straight session, trading above $1 a barrel for the first time since early July.

The discount WTCLc1-LCOc1 widened to as much as minus $4.38 a barrel, suggesting an open arbitrage window.

Elsewhere, India's Reliance Industries RELI.NS has stopped importing Russian crude oil into its refining complex at Jamnagar in western Gujarat state, effective November 20, its spokesperson said on Thursday, tightening global supplies as the refiner seeks alternative barrels.
