There are probably very few activities which are shared by both schoolchildren and our fiscal & monetary policymakers, but blowing bubbles is one of them. The difference being that the kids' bubbles usually consist of soap, are far more entertaining, and cannot cause ruin to entire economies when they pop. But it's the metaphorical asset bubbles that I am more interested in. "Let's sum up: traders are borrowing at negative 20 per cent rates to invest on a highly leveraged basis on a mass of risky global assets that are rising in price due to excess liquidity and a massive carry trade. Every investor who plays this risky game looks like a genius – even if they are just riding a huge bubble financed by a large negative cost of borrowing – as the total returns have been in the 50-70 per cent range since March [2009]....
Metaphorical bubbles and their non-metaphorical problems
Which brings us to the lead story in last week's The Economist. The editorial worries that the loose monetary policies adopted by major economies (printing money; very low interest rates) has created an environment vulnerable to further asset bubbles. In the short term, the side-effect of cheap money on asset prices is being welcomed by many: the profits are helping the market rebound from its earlier downward spiral and firms' balance sheets are being strengthened as a result.
But there are longer-run issues to be concerned about. As the articles explains, "The problem for [investors] is not just that valuations look high by historic standards. It is also that the current combination of high asset prices, low interest rates and massive fiscal deficits is unsustainable." Eventually the cheap money is going to run out when governments scale back their extraordinary measures - this is not a secret. What is not known, however, is whether the process of scaling back is going to be smooth or volatile. History suggests that we cannot assume a smooth transition.
Carry Trade 2009-?
Not all the evidence points to asset bubbles - see The Economist's other article - at least not for the wealthiest economies. Emerging markets, however, are the destination of a lot of this cheap money, which creates its own challenges. To understand why this is so, let's look back to Nouriel Roubini's November editorial about the Mother of All Carry Trades that began in 2009. The "carry trade" is the practice of borrowing in a cheap currency (the USD, with a near-zero - and sometimes negative - interest rate) and investing in risky assets with higher return. Here's Roubini:
Yet, at the same time, the perceived riskiness of individual asset classes is declining as volatility is diminished due to the Fed’s policy of buying everything in sight... By effectively reducing the volatility of individual asset classes, making them behave the same way, there is now little diversification across markets.
Bear in mind that this carry trade is contingent on cheap borrowing. When (not if) borrowing in USD becomes more expensive, this effect will have to reverse itself or shift to a new currency, like the Yen. If this happens suddenly, Roubini believes there will be a stampede "as closing long leveraged risky asset positions across all asset classes funded by dollar shorts triggers a co-ordinated collapse of all those risky assets – equities, commodities, emerging market asset classes and credit instruments."
So maybe this bubble will pop, as Roubini argues it will. Maybe it will simply deflate. The fact is that nobody can say for certain - but the risk is there. Remember the story of Icelandic people blowing up their Land Rovers to avoid paying them off after the krona tanked? That's a dramatic but useful illustration of what happens when the carry trade reverses itself rapidly.
In the meantime, as I alluded to above, the consequences of cheap money flowing to emerging markets are being felt in a number of areas. I'll look at some of the implications in the next installment.
