The US Treasury's decision to expand its long-end buyback programme has reignited market worries about the potential debasement of the US Dollar. According to FX Street, this move has contributed to a weaker USD, alongside stronger gold prices and elevated breakeven inflation rates.

Market participants are interpreting the Treasury's increased buybacks as a signal of growing supply-side pressures, which could undermine the dollar's value. This has led investors to seek refuge in gold, traditionally seen as a hedge against currency depreciation and inflation.

For Japanese investors, these developments are particularly relevant as fluctuations in the US Dollar and gold prices can impact FX and commodity markets, influencing portfolio strategies amid ongoing global economic uncertainties.
