Simply too long. The proper measure of the inversion is not the difference in basis points between short and long rates but the ratio of yields by dividing short rates by long rates. Ratio of short vs long long rate is a better leading indicator of economic recessions and associated credit spread changes going back to 1930. An even better explanation of events on earth including long term cycles in recessions, interest rates, war, and peace are the 11-year sunspot cycles tracked since 1749. The current 25th sun spot cycle is peaking and projected to descend rapidly over the next 5-6 years years. Falling rates, steeper yield curve, and hard landing and peace can not be far behind brought on by human follies and hubris plentiful in Congress, the White House, and among bean counters at the Fed and Wall Street pundits.
