Japanese stocks jumped on Friday, supported by the dollar's surge against the yen, after a U.S. trade deal with Britain fuelled hopes of progress in tariff talks with other countries. Bitcoin soared to the highest since January and U.S. crude ticked up after a more than 3% surge on Thursday, when President Donald Trump announced the agreement with British Prime Minister Keir Starmer - the first in the month since Trump started a 90-day pause on trade tariffs to allow room for negotiations. At the same time, concerns that the limited trade agreement with London may not provide much of a blueprint for additional deals cooled optimism around the outcome of Sino-U.S. trade talks set for Saturday in Switzerland.
