Treasury yields reversed Wednesday's post-PCE calm on Thursday, climbing to levels last seen in 2002 even as the dollar complex stayed choppy. The 10-year U.S. yield touched about 5.34% and the 30-year near 5.69%, CNBC and Reuters said, wiping the "yields ease" read that followed the soft August core PCE print.

Wednesday's Bureau of Economic Analysis release still stands: headline PCE up 0.3% month over month and 3.4% year over year, core at 0.2% and 3.0%. That undershoot versus Wall Street forecasts briefly lowered October Federal Reserve hike odds and let the dollar and front-end rates soften. Thursday's global bond rout — Japan, Germany, France, and the U.K. also sold off — showed long-end rates answering oil and deficit fears more than the one-day inflation surprise.

For households and firms, a mid-5% 10-year yield feeds mortgage and corporate borrowing costs even if the Fed holds in October. Brent's move back above $100 a barrel keeps the oil–yield loop alive after months of Hormuz risk premium. Rate desks still watch Friday's September employment report, ISM manufacturing, and any diplomacy headlines that could knock crude. The soft PCE path is not erased; it now shares the tape with a 24-year high in the benchmark Treasury yield.

Backstory: After months of war-premium oil and heavy Treasury supply, the third quarter delivered the largest jump in U.S. yields this century. Soft inflation data can cool a near-term hike, but it has not yet broken the longer bond sell-off when energy prices reheat. That is why Thursday's open mattered: the market tested whether Wednesday's pause narrative survives another leg higher in long-term rates.
