How important is a bond rating?

A bond rating isn’t the only indicator of quality.

“The perception in the marketplace is a bond with a AAA rating is the crème de la crème,” says Patrick Bradley, a product specialist with the global fixed income team with Brandywine Global Investment Management in Philadelphia. He also co-manages the Renaissance Optimal Income Portfolio.

But that’s not necessarily the case, because rating agencies don’t always have all available information, he says.

“There is a tendency for the rating agencies to lag. French bonds were AAA-rated even as there were concerns that France was going to experience some issues in the management of its fiscal policy and its growth,” he says.

“The U.S. lost its much-vaunted AAA rating because of the financial crisis last year with the raising of its debt ceiling, but bonds actually rallied. So there is more behind purchasing a security than simply looking at credit,” he adds.

Bradley suggests investors do deeper analysis, and use the rating as one factor within that assessment.

“We’re looking at countries that have high real yields – the nominal interest rate less the inflation rate. We also do hard evaluation of a country’s cyclical position: we are looking at economic growth expectations and inflation policy; interest rates and [whether those] rates will rise or fall.”

Bradley also considers a country’s long-term structural factors like whether the country has a credible central bank focused on controlling inflation, as well as a forward-thinking fiscal policy.
