Bubbles that We Have to Worry About and Bubbles We Don't

December 18, 2015

The NYT reported on the reaction in financial markets to the Federal Reserve Board’s decision to raise interest rates on Wednesday. The piece notes the generally calm reaction, but also indicates there continue to be some concern about asset bubbles. It comments:

“Regulators have pointed to a number of worrisome signs in recent weeks. A federal agency said on Tuesday that credit risks were ‘elevated and rising’ for American corporations and many foreign borrowers, even as investors are demanding significantly higher interest rates on junk bonds and foreign debt. The report, by the Office of Financial Research, however, said overall risks to stability remained ‘moderate.'”

It is worth distinguishing the possible bubble in junk bonds and foreign debt from the stock and housing bubbles whose collapse brought on the last two recessions. Both the stock and housing bubbles were driving the economy. They directly generated large amounts of demand through investment spending in the case of the stock bubble and residential construction spending in the case of the housing bubble. Both bubbles also led to consumption booms, as households increased spending based on the ephemeral wealth generated by these bubbles. For this reason, it was 100 percent predictable that the collapse of the bubbles would lead to recessions.

The current bubbles in junk bonds and foreign debt are not in any way driving the economy. Presumably we are seeing somewhat more investment as a result of the fact that uncreditworthy companies were able to borrow at a low cost, but there is no notable boom in such investment. Similarly, if foreign borrowers have a harder time getting access to credit, it may be bad news for them, but the impact on the U.S. economy will be limited.

If some banks or other financial institutions have over committed themselves in these areas, the plunge in prices may threaten their survival. This could lead to some late nights for folks at the Fed and other regulators, but it will not pose a major risk to the economy.
