Tokyo foreign exchange markets began Monday, September 28, with the dollar-yen pair holding in the upper 157-yen range. Although the pair briefly fell below 157 in overseas trading late last week, month-end real-demand buying provided support in Tokyo, alongside elevated U.S. long-term interest rates. Traders are also monitoring the euro-yen rate and supply-demand conditions ahead of the September month-end and quarter-end, with September 30 the final business day of the month.
