  • Though the FOMC’s Sept 26 rate hike surprised no one, in its wake the U.S. Treasury yield curve saw some unexpected changes, reflecting some new economic expectations.
  • In the weeks before the hike, observers fretted about whether the yield of 10-year Treasuries might rise above 3%, potentially flattening the yield curve between 10 and 30 years and heightening nascent concerns about rate hikes moving the economy toward recession.
  • But that’s not how market reaction has played out. The 10-year yield did break the 3% threshold, reaching1 3.214% on Oct 5.  But instead of flattening, the 10- to 30-year portion (the 10-30 spread) rose, steepening the curve. Indeed the spread between the 30 year and 10 year rates reached about 16.5 basis points (bps) on October 4, well above the July 11 low of 10.14 bps when concerns about recession appeared most intense.
  • That’s because the shift was to mostly due to a rise on tne long end, with the 30-year Treasury yield moving as high as 3.39% on October 4th
  • The 30-year is little affected by Fed policy. Instead it tends to reflect bond market expectations for future growth – and the prospect of growth-related inflation. So however slight the rise in the 30-year and the 10-30 spread might be, the signal is no less clear.  
  • The bottom line: the bond market’s assessment of the likelihood of a recession is that it is further in the future – roughly in line with Fed Chairman Powell’s overall optimistic view of a growing economy with no obvious short-term obstacles.

A spread is the difference in yield between two different types of fixed income securities with similar but not identical characteristics, such as maturity, credit quality or currency.



IMPORTANT INFORMATION: All investments involve risk, including loss of principal. Past performance is no guarantee of future results. An investor cannot invest directly in an index. Unmanaged index returns do not reflect any fees, expenses or sales charges.

Equity securities are subject to price fluctuation and possible loss of principal. Fixed-income securities involve interest rate, credit, inflation and reinvestment risks; and possible loss of principal. As interest rates rise, the value of fixed income securities falls. International investments are subject to special risks including currency fluctuations, social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets.

U.S. Treasuries are direct debt obligations issued and backed by the "full faith and credit" of the U.S. government. The U.S. government guarantees the principal and interest payments on U.S. Treasuries when the securities are held to maturity. Unlike U.S. Treasury securities, debt securities issued by the federal agencies and instrumentalities and related investments may or may not be backed by the full faith and credit of the U.S. government. Even when the U.S. government guarantees principal and interest payments on securities, this guarantee does not apply to losses resulting from declines in the market value of these securities.
