Treasuries extended gains Tuesday, pushing yields toward a four-week low as investors positioned for potentially dovish signals from Federal Reserve officials. The bond market rally reflects growing expectations that inflation pressures continue easing.

The two-day advance comes before critical US economic data and speeches from Fed officials that could reinforce arguments for further interest-rate cuts. Markets have already priced in reduced borrowing costs, with bond futures indicating a high probability of additional reductions before year-end.

Investors have shifted toward safe-haven assets amid uncertainty about economic resilience. The second straight day of gains suggests bond traders anticipate weaker-than-expected inflation readings that would validate the Fed's more accommodative policy stance.
