Japan’s currency briefly surged against the dollar amid speculation of what’s known as a “fat-finger,” or accidental, trade. The ruble dropped for a 10th day and Eastern European currencies plunged as the conflict sparked a flight out of the region’s assets. The dollar touched the strongest level in almost nine months versus the euro as data showed German factory orders declined and Italy returned to recession.
