The portrait of Thai King Maha Vajiralongkorn is displayed on a 1,000 banknote baht in an arranged photograph in Bangkok, Thailand, on Wednesday, Sept. 12, 2018. The baht has been a stand-out currency amid the recent rout in emerging markets. It's appreciated 1.5 percent against the dollar so far this quarter, the best performer among major Asian currencies and the only gainer among them.
