Treasury Rate Movements, September 2021

Oct 13, 2021
US treasury rates by maturity

The six-month rate fell, the three-month rate stayed the same, while all other rates rose in September.  The yield curve widened from the previous month thus extending its widening streak to two months.  The one-month bill did not maintain the lowest rate throughout the month and it shared the lowest rate on multiple occasions.  There were moves upwards on short-term rates thus increasing the risk of an inversion brought upon by rising short-term rates.  Such an inversion, if it were to happen would be a strong indicator for an upcoming recession.

Findings

  • The six-month rate fell, the three-month rate remained unchanged, while all other rates rose in September.
  • The seven-year rate had the best absolute performance with a 0.24 point change.
  • On a relative basis, the one-month rate had the best performance with a 133.33 percent change.
  • The six-month rate had the worst absolute performance with a -0.01 point change.
  • On a relative basis, the six-month rate had the worst performance with a -16.67 percent change.
  • The one-month bill did not maintain the lowest rate throughout the month.  The three-month rate held it on several occasions, and the one-month, three-month, and six-month rates shared the lowest rate on several occasions.
  • The yield curve widened from 1.89 to 2.04.

Caveats

  • As always, past performance is not indicative of future results.
  • All figures are rounded to the nearest hundredth.
