Yellen does a Greenspan, talks about “irrational exuberance” in the stock market
Given the American economic growth scenario, an era of low interest rates and easy money is likely to continue in the days to come. And what this means is that the BSE Sensex just might go back to rallying despite the recent fall
Janet Yellen, the chairperson of the Federal Reserve of the United States, said yesterday: “equity market valuations at this point generally are quite high...There are potential dangers there.” This is the strongest statement that Yellen has made against the rapidly rising stock markets in the United States and other parts of the world.
In February earlier this year, Yellen had said the stock prices where “somewhat higher than their historical average levels.” In March, she had followed this up by saying that the stock market valuations were “on the high side”.
Central bank governors don't say things just like that on the stock market, like the stock market analysts tend to do. When a central bank governor makes her view public on the stock market, the idea is to temper down the expectations of stock market investors in some way.
Take the case of a speech that Alan Greenspan, who was the Chairperson of the Federal Reserve between 1988 and 2006, gave on December 5, 1996.
In this speech Greenspan said: “Clearly, sustained low inflation implies less uncertainty about the future, and lower risk premiums imply higher prices of stocks and other earning assets. We can see that in the inverse relationship exhibited by price/earnings ratios and the rate of inflation in the past. But how do we know when irrational exuberance [emphasis added] has unduly escalated asset values, which then become subject to unexpected and prolonged contractions as they have in Japan over the past decade.”
Greenspan was essentially saying that the stock market level might have run way ahead of the kind of earnings that were being generated by companies. And hence there was an “irrational exuberance”.
Greenspan recalls in his autobiography The Age of Turbulence that at the end of the speech, he wondered whether people would understand what he was trying to get at. They sure did.
The Japanese stock market, which had opened by the time Greenspan finished his speech, reacted instantly. The Nikkei index dropped 3.2 percent. The Hang Seng in Hong Kong dropped 2.9 percent. The DAX in Germany went down 4 percent and so did the FTSE 100 in London.
The next day, when the stock markets in the United States opened for trading, the Dow Jones Industrial Average, America's premier stock market index, was down 2.3 percent. The NASDAQ Composite Index, where most of the technology companies listed, was down 1.8 percent at opening.
By the close of trading, the NASDAQ Composite Index was down 0.9 percent and had recovered half of its losses. When the stock market opened for trading again on 9 December 1996, after the weekend, it was back trading at the levels it had been at before Greenspan made the “irrational exuberance” speech.
Various explanations have been offered over the years as to why the stock market investors chose to ignore what Greenspan had said and continued to stay invested in the dotcom bubble. One is that Greenspan did not immediately back his speech with the concrete action of raising interest rates. This argument is not totally correct because Greenspan did raise interest rates a couple of months later, although he did not do anything immediately.
The second reason given is that by the time Greenspan raised the red flag, the market was already irrationally exuberant. It had already formed a mind of its own and was in no mood to listen.
As economist Ravi Batra writes in Greenspan’s Fraud: “The lure of free lunch is so powerful that it clouds our vision. For once Greenspan had offered words of wisdom, but in doing so he lost his audience. The master bartender wanted his customers to sober up. They wanted more: whiskey, champagne, rum, just bring it on.”
The stock market needed a little more than just one Greenspan speech to sober up. A series of interest rate hikes might just have done the trick. But this can only be said with the benefit of hindsight. Nobody likes to spoil a party that is on. Greenspan too was human, and he did not want to be a killjoy.
So what is it that we can learn when we compare Greenspan's warning with those made by Yellen in the recent past. Yellen's warnings on the stock market like that of Greenspan might also have come a little late in the day.
But unlike Greenspan who just made one warning and then more or less kept quiet, until the dotcom bubble burst in 2000, Yellen has come up with a series of warnings. If she keeps saying the things she has been, the investors will eventually take her seriously. The only question is when.
Further, just talking about stock market being overvalued won't help. If Yellen has to rein in the stock market, then the Federal Reserve also needs to start raising the interest rates. The trouble is that with the American gross domestic product (GDP) growing by just 0.2% between January and March 2015, Yellen and the Fed are not really in a position to start raising interest rates.
In fact, what makes the economic situation even more worse than it actually looks is the fact that even a 0.2% economic growth is overstated. This is primarily because it includes a huge inventory build-up. Inventory essentially refers to goods which are being produced but not being sold.
Inventories during the period January and March 2015 went up by $110.3 billion. They had risen by $80 billion during the period October to December 2014. An increase in inventory adds to the GDP. Nevertheless, what it also means is that there will be production cuts in the months to come, which in turn will pull the GDP down.
Albert Edwards of Societe Generale estimates that without this unprecedented rise in inventories, “GDP would rather have declined by some 2½%!” He also said in a recent research note that: “The US economy is struggling and the Fed will ultimately re-engage the QE spigot.”
QE or quantitative easing is the technical term that economists use for a central bank printing money and pumping that money into the financial system to keep interest rates low.
Until October 2014, the Federal Reserve had been printing money and pumping money into the financial system by buying government bonds and mortgaged backed securities. The idea was to flood the financial system with money by buying bonds and drive down interest rates.
At lower interest rates, people were more likely to borrow and spend money. This would help businesses and in turn, the overall economy. While this happened to some extent, what also happened was that institutional investors borrowed money at low interest rates and invested them in financial markets all over the world. This led to stock market rallies all over the world.
Hence, while Yellen might keep making statements about the stock markets being overvalued, she needs to back it up with some concrete action (like raising interest rates) for investors to take her seriously.
The trouble is Yellen can't raise interest rates. At least, not in near future. Given the American economic growth scenario, an era of low interest rates and easy money is likely to continue in the days to come. And what this means is that the BSE Sensex just might go back to rallying despite the recent fall.
