May 29 (Bloomberg) -- President Barack Obama is having a harder time soothing the concerns of bond market vigilantes than stock market investors.

The CHART OF THE DAY shows U.S. Treasury yields rising this week amid record debt sales to the highest level since Obama won the 2008 presidential election. The chart also shows oil prices, an indicator of inflation, rising to Election Day levels.

“At some point, there has to be a recognition of the fact that while President Obama clearly won a resounding victory in winning the White House, he has to win bond vigilantes’ votes every day,” said Edward Yardeni, head of Yardeni Research Inc. in Great Neck, N.Y. “And he’s losing them now. That’s the heart of it.”

Yardeni coined the term “bond vigilante” in 1984 to describe investors who protest monetary or fiscal policies they consider inflationary by selling bonds.

The Standard & Poor’s 500 Index had its biggest two-month rally since the 1930s after Obama said on March 3 that equities offered bargains for investors with a “long-term perspective.”
