- The S&P 500 extended losses in the final hour of trading after trading sideways for the majority of the session. Treasury 10-year yields have risen to near 3.6%. The dollar wavered.

- Short-term inflation expectations in the US unexpectedly fell to their lowest level in more than a year, and consumer sentiment improved, aided by lower gasoline prices. In a separate report, producer prices rose more than expected in November, driven by services, highlighting the stickiness of inflationary pressures that supports Fed interest-rate increases through 2023.

- In the run-up to the Fed meeting, all eyes will be on Tuesday's consumer inflation print, which is expected to show that inflation, while still far too high, has slowed.

Currently, the range is between 3.75% and 4%.
