On Friday, U.S. Treasury yields rose slightly due to investors' growing expectations of a Fed interest rate hike in December.

The yield on 10-year U.S. Treasury bonds – a key benchmark for mortgage loans, auto loans, and credit card debt – rose by 2 basis points to 5.1271%.

The yield on 30-year U.S. Treasury bonds, which have a longer maturity and are generally more sensitive to geopolitical risks, rose by 3 basis points to 5.4602%. In contrast, the yield on 2-year U.S. Treasury bonds, which are usually more responsive to the Federal Reserve's short-term interest rate decisions, fell by 1 basis point to 4.8525%.

1 basis point is equal to 0.01%, and the yield rate moves in the opposite direction to the price trend.

Previously, the yield on 10-year U.S. Treasury bonds soared by more than 13 basis points during trading on Thursday, breaking through 5%; the yield on 2-year bonds also increased significantly by more than 15 basis points.

Investors now almost certainly expect the Federal Reserve to raise interest rates next month. According to the CME Group's ( CME Group ) FedWatch tool, traders are pricing in a 100% probability of a rate hike at the meeting on December 9th. Currently, the market believes that the probability of a 25-basis-point rate hike is close to 87%, while the probability of a 50-basis-point rate hike is about 13%.

Energy inflation remains a focal point of market concern. As the prospect of the United States launching another attack on Iran diminishes, oil prices are expected to fall for the second consecutive week. On Friday morning, oil prices were volatile. Futures for West Texas Intermediate crude oil delivered in December fell by 0.1% to $88.63 per barrel; Brent crude oil rose by 0.3% to $96.11 per barrel.

The U.S. Producer Price Index ( PPI ) for October will be released later on Friday, which is an important indicator of wholesale inflation. The market expects this index to grow by 0.4% last month, lower than the 1.3% reported in September.
