The yen fell to 157.54 against the dollar on Friday. Global bond yields rose as central banks signaled further tightening.

The Japanese yen fell to 157.54 against the dollar on Friday. The currency dropped approximately 1% in a single session. This decline marks the weakest weekly performance for the yen in two years. The drop occurred despite the Bank of Japan raising its policy rate. The central bank lifted rates to 1.25%, a 31-year high. Two board members opposed the decision. Governor Kazuo Ueda stated that underlying inflation is approaching the 2% target. He noted that most policymakers still view conditions as accommodative.

Investors focused on the widening interest rate gap between Japan and the United States. The Federal Reserve raised rates earlier in the week for the first time in three years. This move reinforced expectations that global borrowing costs will remain high. Chris Scicluna of Daiwa Capital Markets Europe warned of additional pressure on the yen. He suggested the Bank of Japan could hike rates to 1.50% by year-end. This would occur if domestic demand and inflation remain strong.

Central banks tighten policy globally

September recorded the largest increase in average G10 interest rates since July 2023. Four central banks raised rates during the month. The Bank of England held rates steady but warned of inflation risks. It cited the prolonged war in the Middle East as a key factor. The European Central Bank signaled that further tightening is possible. Australia’s central bank noted that previous inflation risks are now materializing.

The shift in policy reflects growing concern over persistent price growth. Markets reacted to a broad move toward tighter monetary conditions. The Federal Reserve adopted a more aggressive stance on inflation. This action contributed to the pressure on the yen. It also reinforced the outlook for elevated global borrowing costs. According to GN markets/inflation (en-US) data, the trend indicates a sustained hawkish turn.

Oil prices ease on supply hopes

Brent crude fell 2.8% on Friday to $101.92 per barrel. The decline followed reports that China asked Tehran to restrain the Houthis. Gulf exporters are also seeking alternative routes for crude transport. These developments eased some immediate supply concerns. Brent prices are on track for a weekly decline of 2%. Physical market prices remained significantly higher at around $120 per barrel.

Central banks remain cautious about the broader inflation threat. A temporary drop in futures prices does not eliminate the risk. Prolonged energy supply disruptions could keep consumer prices elevated. The conflict in the Middle East continues to complicate monetary policy. Higher energy costs feed directly into broader inflation metrics. This dynamic forces banks to maintain a hawkish posture.

Bond yields reflect rate outlook

Bond markets have absorbed the changing interest rate environment. U.S. Treasury yields surged during the week. The rise in yields reflects the Federal Reserve’s tightening. It also mirrors the actions of other major central banks. Investors are pricing in higher costs for longer. The pressure on global stocks and bonds persists. The market remains sensitive to signals from policymakers.
