  • What's behind the surprising shift in yields of U.S. Treasuries since the beginning of this year? Is it the result of benign economic progress, or a sign of something more ominous?
  • The U.S. Treasury (UST) yield curve has flattened noticeably this year—along with many sovereign yield curves worldwide.
  • While the rise in short-term rates is no surprise given the Fed's rate hikes over the past year, longer maturities are a different matter.
  • The downward move in the long end of the yield curve was a surprise to some market watchers, who expected improving global growth to lift inflation, which would in turn put upward pressure on longer-term bond yields.
  • Instead, inflation has been missing in action in much of the world economy.
  • That means investors searching for even a modest yield pickup in government-issued securities have had to buy longer maturities than they might otherwise have preferred.
  • Many observers believe the combination of low inflation and higher demand for long-dated bonds are keeping downward pressure on longer-term bond yields, leading to a flatter yield curve.
  • But there's another possibility: the market could be anticipating a slowdown in growth in the U.S., as well as a potential pause in the Federal Reserve’s well-telegraphed path to higher interest rates.
  • Certainly, a flattening yield curve – at least in the past – has typically been a harbinger of slower growth; recent soft U.S. economic reports lend some support to the possibility.
  • But it’s still too early know for sure. And the curve would probably need to flatten a lot more before it becomes a clear signal of a slowdown.
  • When you consider a country like Germany, whose yield curve has also flattened this year despite its strengthening  economy, it's clear that other factors could very well generate similar shifts in sovereign-market interest rates.
  • And only time will tell if markets are expecting continued growth—albeit at a very moderate pace—without any meaningful inflation. Or if more ominous news is around the next corner.
