Treasury stamps 5% coupon on 10-year notes, the richest since 2006

The U.S. Treasury announced a 5% coupon on its 10-year notes, the highest rate attached to the benchmark since 2006. The move lands as the 10-year yield hovered around 4.99%, following a 13 basis point increase.

Behind the sticker price: stronger-than-anticipated inflation data that has hardened expectations the Federal Reserve will keep hiking rates. For the Treasury, the coupon is the cost of managing borrowing in a market that isn't pricing relief anytime soon.

Attention now swings to the Fed's calendar. FOMC statements, fresh inflation reports and labor market data are the inputs traders will use to reset rate expectations, according to Crypto Briefing.

Two more tripwires sit on the radar: any surprise shift in Treasury issuance strategy and big swings in global economic conditions, either of which could bend the current yield trajectory. Markets are also watching whether the 5-year yield can break below key thresholds, a move that would flag a change in the rate outlook.
