US Treasury yields have surged to levels not seen since 2007, driven by rising oil prices and ongoing bond buybacks. According to FX Street, the 30-year US Treasury note yield has surpassed 5.3%, approaching the high set before the financial crisis.

The 10-year Treasury yield also rose sharply, hitting 4.865% on Thursday. This represents a 25 basis point rally in less than two weeks and a 0.5 percentage point increase since late June, highlighting strong demand shifts in the bond market.

For Japanese investors, these developments signal increased volatility in global fixed income markets, potentially impacting yen-based assets and influencing Bank of Japan policy considerations amid shifting international yield dynamics.
