If the insatiable demand for bonds has upended the models you use to value them, you’re not alone.
Just last month, researchers at the Federal Reserve Bank of New York retooled a gauge of relative yields on Treasuries, casting aside three decades of data that incorporated estimates for market rates from professional forecasters. Priya Misra, the head of U.S. rates strategy at Bank of America Corp., says a risk metric she’s relied on hasn’t worked since March.
After unprecedented stimulus by the Fed and other central banks made many traditional models useless, investors and analysts alike are having to reshape their understanding of cheap and expensive as the global market for bonds balloons to $100 trillion. With the world’s biggest economies struggling to grow and inflation nowhere in sight, catchphrases such as “new neutral” and “no normal” are gaining currency to describe a reality where bonds are rallying the most in a decade.
“The world’s gotten more complicated and it’s a little different,” James Evans, a New York-based money manager at Brown Brothers Harriman & Co., which oversees $30 billion, said in a telephone interview on May 30. “As far as predicting direction up and down, I don’t think they have much value,” referring to bond-market models used by forecasters.
