GBP/JPY Enters New Phase as Japanese Policymakers Turn Hawkish

The British pound (GBP) against the Japanese yen (JPY) has entered a more complicated phase after months of elevated levels. The pair's performance is influenced by the interest-rate gap between the UK and Japan, but this advantage is shifting as Japanese policymakers become increasingly concerned about inflation and currency weakness.

The Bank of Japan's rate is now 1%, with another increase possible if inflation and economic conditions support it. Elevated UK yields continue to support sterling, creating a contest between pound returns and a yen that is becoming less attractive as a funding currency.

The upcoming September 17-18 Bank of Japan meeting represents a major event risk for the cross. A rate increase or distinctly hawkish guidance could strengthen the yen, particularly if investors believe another adjustment may follow relatively soon.
