Other than construction-related industries, "we expect to see other areas benefiting," especially in the last three months that national currencies are accepted, said William Dinning, a global investment strategist at UBS Warburg. Luxury watch makers, jewelers, hoteliers, auction houses and wine merchants may all get a boost, he said.
