Federal Reserve Governor Christopher Waller discussed the role of forward guidance in monetary policy, noting that while it can enhance the effectiveness of policy measures, it might also reduce the flexibility of policymakers, according to FX Street.

Meanwhile, silver prices (XAG/USD) halted a four-day winning streak on Monday following a 5.55% rally last week, with gains curbed by a stronger US Dollar, FX Street reported. The firmer dollar typically weighs on precious metals by making them more expensive for holders of other currencies.

For Japanese investors, the interplay between US monetary policy signals and dollar strength remains crucial, especially as it influences commodity prices and emerging market currencies like the South African rand.
