Oil futures end at highest since May (by Claudia Assis)
SAN FRANCISCO (MarketWatch) -- Crude-oil futures gained 1.5% on Thursday, settling at their highest since May, after a smaller-than-expected increase in weekly inventories and on a lower dollar. Oil for April delivery (clj2) advanced $1.55 to settle at $107.83 a barrel on the New York Mercantile Exchange. Other energy products tracked oil higher, with natural gas the outlier even as its own weekly inventories report showed a larger-than-expected decline in inventories.
