■ Warning of Additional Fed Tightening... A Key Variable for Gold Prices

Separately, an investment bank has warned that markets should prepare for the possibility of U.S. benchmark interest rates rising above 5% again.

In a recent report, Bank of America strategists including Mark Cabana and Meghan Swiber projected that the U.S. Federal Reserve could raise benchmark rates to levels similar to the 2022-2023 tightening period. At that time, the upper bound of the U.S. benchmark rate rose to 5.5%.

Bank of America assessed that financial markets are still underestimating the Fed's terminal rate level. The current interest rate swap market expects the Fed to raise benchmark rates three more times, bringing the effective federal funds rate to around 4.5-4.75%.

Accordingly, in the gold market, the intensity of additional Fed tightening and movements in U.S. Treasury yields are expected to be key variables to watch.
