They're back. We refer to the global investors once known as the bond vigilantes, who demanded higher Treasury bond yields from the late 1970s through the 1990s whenever inflation fears popped up, and as a result disciplined U.S. policy makers. The vigilantes vanished earlier this decade amid the credit mania, but they appear to be returning with a vengeance now that Congress and the Federal Reserve have flooded the world with dollars to beat the recession.
Treasury yields leapt again yesterday at the long end, with the 10-year note climbing above 3.7%, its highest close since November. Treasury yields had stayed low, and the dollar had remained strong, as long as investors were looking for the safest financial port amid the post-September panic. But as risk aversion subsides, and investors return to corporate bonds and other assets, investors are now calculating the risks of renewed dollar inflation.
