Rates must go substantially higher before bonds can challenge the return on stocks. By Jeremy J. Siegel, Contributing Columnist May 4, 2012 The bond market, like the canary in a coal mine, senses when there is a change in economic activity. From the beginning of February to mid March, the yield on the ten-year Treasury bond jumped by more than a half-percentage point, signaling that traders believe the Fed’s policy of keeping short-term interest rates at record low levels may be coming to an end. With strong payroll gains and glimmers of a revival in the housing market, the case for a sustained economic recovery is strong. That means it’s unlikely the Fed will be able to maintain its near-zero rates well into 2014, as it has indicated it would do in recent policy statements.

The price of the ten-year Treasury bond fell by about 4.6% in February and March, wiping out more than two years’ worth of interest rate payments. And although rates have since moved back down, it is only a matter of time before they rise again. This will be bad news for all the investors who piled into bond funds -- especially Treasury bond funds -- over the past five years. Many investors worry that rising rates will also spell the end of the recent bull market in stocks, which have risen nearly 30% from their lows of last October. But you can put those fears to rest. In the past three decades, the onset of higher Fed interest rates has caused stocks to stumble at first, but it has never ended their bull run. Advertisement For example, when the Fed began to raise rates in February 1994 following the 1990-91 recession, the market fell 9% in the next two months. But stocks quickly recovered and entered one of the longest bull markets in history. By the time the charge was over in March 2000, Standard & Poor’s 500-stock index was two-and-one-half times higher than it was when the Fed began raising rates. Similarly, the Fed started to raise interest rates at the end of June 2004, following the 2001 recession, and the market fell 7% through August. But stocks recovered and began a bull run that culminated in October 2007. The conventional wisdom is that rising interest rates are bad for stocks. But the Fed would not raise rates unless it anticipated a stronger economy, and that’s good for corporate profits. It’s only when a long economic expansion causes firms to hit capacity and the labor market to tighten that the Fed is forced to raise rates decisively to slow economic activity. With current unemployment above 8% and factories operating at less than 80% of capacity, the U.S. economy is nowhere near that point. A Costly Wait Because the market has usually stumbled when the Fed begins raising rates, you might ask whether you should wait until the Fed signals an end to its low-interest-rate policy before getting into stocks. I would answer no. I believe the Fed will begin raising rates well before the end of 2014, but stocks could be much higher than they are today when that first rate hike occurs. So waiting could cost you an opportunity.

So Bernanke will likely indicate that the Fed is ready to shift gears well in advance of the first rate hike, giving the markets plenty of time to adjust. Investors should view the increase in Treasury yields as a herald of better times to come, not as a development that will end the bull market in stocks. Today, U.S. stocks are trading at 13 times estimated 2012 earnings. That is well below the average of 19 that prevailed in low- and moderate-interest-rate environments over the past 50 years.
