The yield on the 10-year U.S. Treasury note climbed to 5.37%, and the 30-year yield rose to 5.73%, both reaching their highest levels since 2002. Brent crude oil prices rebounded to $106 per barrel due to tensions in the Strait of Hormuz. The market is pricing in a roughly 20% probability of a rate hike at the October 28 FOMC meeting, while the December rate hike expectation remains around 70%.
