Today's Fed rate decision will be announced at 11am PT / 2pm ET. The market is currently projecting a 93% probability that there's a 25-bp rate hike. One other place this probability shows up is with 1-Month Term SOFR.
We simplify loan pricing by saying "SOFR + 2.50%", but the reality is almost every lender is using 1-Month Term SOFR which is based on futures contracts and reflects market expectations for SOFR over the coming month.
For most of 2026, overnight SOFR and 1-Month Term SOFR tracked in the 3.60s. However, these rates started to diverge at the beginning of September when the market began repricing the probability of a Fed rate hike on September 16th (today).
1-Month Term SOFR has already increased 25 bps to 3.89% this morning, while overnight SOFR is still 3.64%.
For those that have floating rate agency loans, it's worth noting that the agencies do not use 1-Month Term SOFR, but 30-day Average SOFR which is backwards looking. So the impact of today's hike will be reflected gradually in your interest expense over the following 30 days, rather than immediately.
