TWO groups seem to be staring at each other in mutual incomprehension at the moment; investors and economists. Judging by the behaviour of stockmarkets so far this year, the former are very worried about the global outlook. But the latter think investors are panicking for no good reason.
Market movements (and much commentary) suggest that the big concerns are the Chinese economy (and its effect on global output), and the possibility that the Federal Reserve might have tightened monetary policy too soon, given the recent weakish figures on the American economy. But economists believe that China, whole slowing, is hardly collapsing and that falling oil prices are generally a positive, rather than a negative, sign.
Take Olivier Blanchard, the former IMF chief economist who just published his first blog for the Peterson Institute. Having examined the Chinese and US economic outlooks, he thinks it is hard to justify the market movements. So what explains the market movements? (http://blogs.piie.com/realtime/?p=5341) He concludes that
to a large extent, herding is at play. If other investors sell, it must be because they know something you do not know. Thus, you should sell, and you do, and so down go stock prices.
In a note to clients, entitled Let s analyse our fears , Torsten Slok of Deutsche Bank puts markets on the analyst s couch before concluding that
The bottom line is that I see the recent turbulence out of China as temporary issues related to liberalizing their economy and not driven by a hard landing scenario playing out. And even if there is a harder landing in China I struggle to quantify the transmission channels to the US.
The fears I discuss with clients are temporary and will go away once we have the worst behind us in terms of oil price declines and dollar appreciation.
Writing in Prospect magazine, George Magnus, a shrewd veteran observer, is less upbeat than that but still concludes
even if the equity markets are in a bad mood, that doesn t mean we have to conflate this with another imminent global recession. The most likely outcome, assuming that there is no rout in equity markets, is that we will muddle through a period of economic weakness.
Economists tend to be a bit sniffy about the prescience of markets. "Wall Street indexes predicted nine of the last five recessions" quipped Paul Samuelson, this from a man whose textbook regularly forecast that the Soviet Union's economy would outstrip that of the US. It is certainly true that markets can get ahead of themselves, on both the up- and the downside. However, despite their disdain, economists do use markets as a predictive tool; the Conference Board's leading indicator incorporates two measures - the S&P 500 indicator and the spread between long and short interest rates.
Using these measures is understandable. A huge fall in equity markets will dent consumer confidence (although not as much as a fall in house prices, of which there is no sign). A flattening or inverting yield curve (long rates below short rates) is often a sign of a recession (largely because central banks are pushing up rates to head off inflation.)
So should we believe the markets or the economists? Writing in the FT last week, Larry Summers pointed out that
markets understood the gravity of the 2008 crisis well before the Federal Reserve
and worried that
It is especially ominous when markets fail to rally on what should be good news
As a colleague pointed out, it is tempting to believe the markets only when they are sending a message that coincides with your pre-existing views. So having been warning for a while about the sighs of a global slowdown (look at the sluggish growth of global trade, nothing to do with financial markets), I am inclined to think the markets are onto something.
The big problem, however, is that market signals are not what they used to be. Central banks are still buyers, or huge owners, of government bonds; are yields really a measure of investor sentiment? Very low, or negative, interest rates dissuade investors from holding cash and encourage them to buy risky assets; so are equity prices and corporate bond yields a "true" measure? Given that the Fed took the first step in withdrawing the stimulus last month, are market movements an indicator of economic activity or a sign that investors are worried that Daddy is about to cut off their allowance?
