World shares jumped on Thursday, with Tokyo's Nikkei 225 gaining almost 6% to a new record as investors waited to see if the U.S. and Iran will strike a deal allowing tankers to deliver crude from the Persian Gulf again.

Japan's benchmark Nikkei 225 index jumped more than 3,300 points to 63,086.00 as markets in Tokyo reopened following “Golden Week” holidays.
