The 10-year Treasury yield fell below 5% on Thursday for the first time in a month, then stood at 4.99% on Friday, October 23, up 3 basis points on the day, CNBC reported. The two-year yield was 4.68%. The 30-year yield was 5.31%.

Those yields help price new mortgages, car loans, and credit-card offers. Falling back under 5% does not change a fixed payment already signed. Lenders may follow the yield on new credit, but Friday's rebound of a few basis points shows the dip was not locked in.

CNBC tied the bond buying to a retreat from technology shares, even as oil stayed firm. The Federal Reserve's range remains 3.75% to 4.00%, and no move was expected at next week's meeting. A FedWatch gauge put the odds of a December quarter-point hike near 70%. That is pricing, not a decision.

Michigan's final October sentiment index was 48, above a preliminary 46.3. Year-ahead inflation expectations were 4.7%, up from 4.6% in September. Expectations are not a bill.

Does a 4.99% Treasury yield change the payment on a fixed-rate loan you already have? No. It does not reset an existing fixed payment. It can affect new borrowing if lenders follow the yield.
