The USD/JPY pair rises to 154.35 during the Asian session as the Yen strengthens against the Dollar for the fourth consecutive session, nearing a 12-week high. This is due to traders unwinding carry trades ahead of the Bank of Japan's expected rate hike and bond purchase tapering. Recent strong US PMI data supports the Federal Reserve's restrictive policy. Investors await US GDP and PCE inflation data, indicating potential volatility ahead of key central bank events.
