What happened

The two-year US Treasury yield reached a new multi-year high after the Federal Reserve raised rates on Wednesday and Chair Kevin Warsh's remarks left markets with the impression that more increases could come wsj.comqz.com. The front end stepped up again, with two-year yields at 4.75 per cent, the highest since 2024 investinglive.com. Intraday, the two-year touched its highest level since July 2024 indexbox.io.

The Fed increased its target range by 0.25 percentage points, to 3.75 per cent to 4.00 per cent fxempire.com. The dot plot published alongside the decision showed 16 of 18 Fed officials penciling in another rate hike this year, and Warsh delivered a hawkish speech bloomberg.com.

Why it matters to investors

The curve has kept flattening since the decision, with the spread between two- and ten-year yields narrowing indexbox.io. That spread was last at 25.5 basis points, after earlier reaching 23.8 basis points, the flattest since June 25 fidelity.com. At 4.75 per cent the front end is close enough to ten-year yields that traders have started to think about inversion again investinglive.com.

The sell side is positioning for more. Bank of America has warned that Warsh's Fed could raise rates above 5 per cent, a repeat of 2022 finance.yahoo.com, and the same strategists are recommending that clients short two-year Treasuries fa-mag.com. Warsh was careful not to commit to any future move while reaffirming his dissatisfaction, according to their note finance.yahoo.com.

What to watch

The direction is not one-way. US Treasury yields fell on Friday, mirroring the broader global bond market, as the curve flattened further news.futunn.com. The flattening, not the level, is the signal: it says the market expects tightening to bite growth rather than to persist at the long end indexbox.iofidelity.com. A front end that keeps rising while the long end stalls is the market pricing a shorter, sharper cycle rather than a durably higher rate structure investinglive.comindexbox.io.

The gap between the committee and the curve is the thing to size. The dot plot points to one more increase bloomberg.com; the front end is priced as though there could be more than one, and Bank of America has told clients to position for a peak above 5 per cent finance.yahoo.comfa-mag.com. Chair Warsh's reluctance to give forward guidance leaves that gap open rather than closing it, which is why the repricing continued for days after the meeting itself wsj.comqz.com.

Two things settle the argument from here: whether the additional hike in the dot plot arrives bloomberg.com, and whether the two-to-ten spread crosses zero from its current handful of basis points fidelity.cominvestinglive.com.
