Yen Weakness Reignites Intervention Watch Amid Oil Price Volatility
Tokyo's stock market was closed on September 21 for Respect for the Aged Day, leaving the Nikkei 225 without a cash close after finishing the previous session at 65,019.
The break came immediately after one of the most important policy weeks of the year, with the Federal Reserve raising interest rates and the BOJ lifting its policy rate to 1.25%, the highest level in 31 years.
The yen traded near 157 to the dollar as investors continued to digest the BOJ's September 18 decision, which failed to strengthen the currency due to two dissenting votes and a lack of explicitly hawkish guidance.
The reaction was a reminder that markets had already priced in the September rate increase, and investors were looking for signals on further rate hikes in December and beyond.
