Gold prices climbed steadily on Friday, gaining nearly 0.90%, following the release of weaker-than-expected US inflation data. This softer inflation report lowered market expectations for an upcoming Federal Reserve interest rate hike, leading to a decline in the US Dollar's value, according to FX Street.

The precious metal traded near the $4,386 level, moving closer to the $4,400 mark as investor sentiment shifted towards safer assets amid reduced concerns over aggressive Fed tightening. The softer inflation outlook has eased pressure on the Federal Reserve to raise rates further this week.

For Japanese investors, these developments are notable as fluctuations in the US Dollar and gold prices can impact forex and commodity portfolios, particularly given Japan's role as a major holder of gold reserves and its sensitivity to US monetary policy shifts.
