on the month +24bp
Moves are how far each maturity travelled over a span, in basis points.
Change in Treasury Bills at 7 maturities over 7 spans to 2 Oct 2026, led by the 1Y at +30bp on the month.
Short-term Treasury bill rates from 4 weeks to 52 weeks, quoted coupon-equivalent so they compare with a coupon bond.
Moves are how far each maturity travelled over a span, in basis points. Spans stack together, from one session out to three years.
Rows are maturities, columns are how far back; the spans nest. Each cell is a change over its span, in basis points.
Down a column gives the shape of one move. Along a row is whether that maturity kept going or gave it back.
A 6M row reading +3 on the day and −18 on the month has given back part of a fall.
Depth measures the move against this curve’s record at that span, so a deep cell is an equally rare move in any column. A cell that did not move takes no colour; n/a means the print never came.
