Is A Tightening Yield Spread Still A Warning Sign For The Economy?

The Federal Reserve is expected to raise interest rates today – at a time when the Treasury yield spread has become relatively compressed. That’s a warning sign, according to the historical record. The question is whether the shelf life for this analysis has expired.

Tim Duy, a professor at the University of Oregon, reminds that “recent history suggests that the greatest risk of recession occurs if the Fed continues to tighten after the initial inversion of the yield curve, which happened prior to the last two recessions.” The curve isn’t inverted, but it’s getting close. Meantime, the Fed is widely expected to lift interest rates again today, laying the ground work for squeezing the curve a bit more.

Consider the 10-year/2-year Treasury yield spread, which fell to 83 basis points yesterday (June 13), based on daily data via Treasury.gov. That’s the smallest spread since last October and slightly below the long-term average of 93 basis points over the past four decades.
