The session's yields

The 10-year yield rose more than 13 basis points to 5.104 per cent. The 2-year rose more than 11 basis points to 4.889 per cent, and the 30-year rose more than 9 basis points to 5.398 per cent. The long end last traded at this kind of level in July 2007, and the 30-year in June 2007.[1]

The day's move was the biggest since 7 April 2025, when the yield surged 16.6 basis points. A survey, an auction and one Fed official's base case stand beside that jump on the same morning.[1]

Three inputs from the same morning

S&P Global's services PMI rose to 58.7 in September from 56.5, and the manufacturing PMI rose to 56.7. The survey says activity sped up, and it marks the priced growth and cost pace higher.[1]

The five-year auction cleared at 5.033 per cent, against a six-auction average of 4.186 per cent. Indirect bidders, the group that includes global central banks, took 54 per cent of the sale, against a 65 per cent average. The auction met weak demand. A price that had already moved before the sale is part of the same morning.[1]

Michael Barr said further policy adjustments are likely to be needed in his base case so inflation comes down to target. CME FedWatch put the chance of an October increase at 66.4 per cent, from 55 per cent a day earlier. The Federal Reserve raised the funds rate last week by 25 basis points to a range of 3.75 per cent to 4 per cent. The two-year yield, at 4.889 per cent, is at its highest since May 2024. That end tracks the policy bet. The long end is looking at the auction and at the survey's cost line.[1]

The easing did not hold

On 22 September this column had long yields eased while short rates stayed high. That easing did not hold. The 10-year yield rose more than 13 basis points to 5.104 per cent.[2], [1]

Indirect bidders at 54 per cent sat below the 65 per cent average. That could be a thin auction, and the services PMI at 58.7 plus Barr's line on further adjustments could also be what carried the yield onto a new path. The observation that separates them is whether the 2-year yield holds near 4.889 per cent. If that end gives the move back once the auction day passes, the session looks like a demand air-pocket. If 4.889 per cent holds, the survey and the base case have stuck to the price more tightly.[1]
