Treasury Rate Movements, October 2017

Nov 1, 2017
US treasury rates by maturity

Short-term rates continued their steady rise in October and medium and long-term rates tempered their rise from the previous month.  The yield curve narrowed after widening in the previous month.  Short-term rates have slowed their rise in rates but October breaks with the previous two months where the one-month bill had a session with higher rates than the three-month bill.  That is, the one-month bill maintained the lowest rate throughout the month for the first time in three months.  That is a promising sign as a narrowing of the yield curve from the bottom up has been a steadfast indicator of recession.  All rates rose in October.


  • All maturities' rates rose in October with the two-year rate rising the most in absolute terms and the one-year rate rising the most in relative terms.
  • The one-month bill maintained the lowest rate throughout the month for the first time in three months.
  • Medium and short-term rates rose faster than long-term rates on a percentage basis.
  • The yield curve narrowed by one-hundredth of a point.


  • As always, past performance is not indicative of future results.
  • The rates have been at historic lows for quite some time which has not occurred previously.
