Yen slumps after BOJ hikes rates as expected

The Japanese yen experienced a significant drop against its major trading partners on Friday, following the Bank of Japan's anticipated interest rate hike. The currency weakened as much as 0.8%, reaching 157.145 yen per dollar, its lowest point since September 3. This decline continued even after the Bank of Japan raised interest rates to their highest level in over three decades, with a decision not unanimously agreed upon by all board members.

The yen's performance against the euro was also weaker, falling 0.8% to 180.32 yen. A National Australia Bank representative noted that the BoJ's decision fell short of market expectations, causing significant concern. The yen's decline followed data indicating steady core inflation near the central bank's 2% target in August, signaling heightened price pressures.

Investors are now focusing on Governor Kazuo Ueda's press conference, where he will provide insights into the central bank's decision. The market will be watching for confirmation of continued normalization and assessing urgency for further action. Meanwhile, other currencies such as the British pound, euro, Australian dollar, and New Zealand dollar also saw fluctuations in response to recent economic data and central bank policies.
