Arcane Piece of Data Used to Predict Next US Recession Ken Bredemeier WASHINGTON - When U.S. economists and stock market analysts ponder whether an economically debilitating recession is on the horizon, they often look to an arcane piece of data: whether a yield curve inversion of interest rates on government bonds is occurring. It's called an inverted yield curve. Specifically, they look at the interest rates for two- and 10-year U.S. Treasury notes. Typically, interest rates on longer-term government bonds are higher than those for shorter periods of time. But when that interest rate phenomenon is reversed, as occurred Wednesday, it can be a sign that investors have worries about the immediate state of the U.S. economy, the world's largest, and are demanding a higher rate of return on the shorter-term notes. The yield on a 10-year Treasury note briefly hit 1.622%, dropping below the 1.634% yield for a two-year bond, although the longer-term yields moved higher in later trading compared to that for the two-year notes, and remained higher in early Thursday trading. Despite Wednesday's yield curve inversion, former Federal Reserve chair Janet Yellen said she does not think the U.S. is headed to a recession. "I think the U.S. economy has enough strength to avoid that," she said. "But the odds have clearly risen, and they are higher than I'm frankly comfortable with." .
