"Currency Carry Trades" -- Roubini Warns of Another Bubble

By John Ballard

Okay, ya'll.
If and when it happens, just remember you read it here first.

Noriel Roubini is very smart. He was among the few economists who saw last year's economic collapse the year before. They don't call him Doctor Doom for nothing. So this most recent warning is neither obscure nor hard to grasp. His reasoning is clear and reasonable.

To understand Roubini's concern I had to look up "carry trades," one of those terms that economists take for granted but us lay people need to learn about.

What Does Currency Carry Trade Mean?

Investopedia explains Currency Carry Trade

Here's an example of a "yen carry trade": a trader borrows 1,000 Japanese yen from a Japanese bank, converts the funds into U.S. dollars and buys a bond for the equivalent amount. Let's assume that the bond pays 4.5% and the Japanese interest rate is set at 0%. The trader stands to make a profit of 4.5% as long as the exchange rate between the countries does not change. Many professional traders use this trade because the gains can become very large when leverage is taken into consideration. If the trader in our example uses a common leverage factor of 10:1, then she can stand to make a profit of 45%.

The big risk in a carry trade is the uncertainty of exchange rates. Using the example above, if the U.S. dollar were to fall in value relative to the Japanese yen, then the trader would run the risk of losing money. Also, these transactions are generally done with a lot of leverage, so a small movement in exchange rates can result in huge losses unless the position is hedged appropriately.

Got that?

Good.

Now see here what Roubini describes as "the mother of all currency carry trades."

Since March there has been a massive rally in all sorts of risky assets � equities, oil, energy and commodity prices � a narrowing of high-yield and high-grade credit spreads, and an even bigger rally in emerging market asset classes (their stocks, bonds and currencies). At the same time, the dollar has weakened sharply , while government bond yields have gently increased but stayed low and stable.

A strategy in which an investor sells a certain currency with a relatively low interest rate and uses the funds to purchase a different currency yielding a higher interest rate. A trader using this strategy attempts to capture the difference between the rates, which can often be substantial, depending on the amount of leverage used.

This recovery in risky assets is in part driven by better economic fundamentals. We avoided a near depression and financial sector meltdown with a massive monetary, fiscal stimulus and bank bail-outs. Whether the recovery is V-shaped, as consensus believes, or U-shaped and anaemic as I have argued, asset prices should be moving gradually higher.

But while the US and global economy have begun a modest recovery, asset prices have gone through the roof since March in a major and synchronised rally. While asset prices were falling sharply in 2008, when the dollar was rallying, they have recovered sharply since March while the dollar is tanking. Risky asset prices have risen too much, too soon and too fast compared with macroeconomic fundamentals.

So what is behind this massive rally? Certainly it has been helped by a wave of liquidity from near-zero interest rates and quantitative easing. But a more important factor fuelling this asset bubble is the weakness of the US dollar, driven by the mother of all carry trades. The US dollar has become the major funding currency of carry trades as the Fed has kept interest rates on hold and is expected to do so for a long time. Investors who are shorting the US dollar to buy on a highly leveraged basis higher-yielding assets and other global assets are not just borrowing at zero interest rates in dollar terms; they are borrowing at very negative interest rates � as low as negative 10 or 20 per cent annualised � as the fall in the US dollar leads to massive capital gains on short dollar positions.

Let us 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.

People�s sense of the value at risk (VAR) of their aggregate portfolios ought, instead, to have been increasing due to a rising correlation of the risks between different asset classes, all of which are driven by this common monetary policy and the carry trade. In effect, it has become one big common trade � you short the dollar to buy any global risky assets.

My forte is not economics but I am smart enough to pay attention when someone who is a card-carrying expert says something. My expertise is in food management (where everyone is an expert, you know) so I am well aware of how off the mark a non-professional can get with just enough information to get into trouble.

Here's more.

The reckless US policy that is feeding these carry trades is forcing other countries to follow its easy monetary policy. Near-zero policy rates and quantitative easing were already in place in the UK, eurozone, Japan, Sweden and other advanced economies, but the dollar weakness is making this global monetary easing worse. ... if there is no forex intervention and foreign currencies appreciate, the negative borrowing cost of the carry trade becomes more negative. If intervention or open market operations control currency appreciation, the ensuing domestic monetary easing feeds an asset bubble in these economies. So the perfectly correlated bubble across all global asset classes gets bigger by the day.

But one day this bubble will burst, leading to the biggest co-ordinated asset bust ever [...]

Why will these carry trades unravel? First, the dollar cannot fall to zero and at some point it will stabilise; when that happens the cost of borrowing in dollars will suddenly become zero, rather than highly negative, and the riskiness of a reversal of dollar movements would induce many to cover their shorts. Second, the Fed cannot suppress volatility forever � its $1,800bn purchase plan will be over by next spring. Third, if US growth surprises on the upside in the third and fourth quarters, markets may start to expect a Fed tightening to come sooner, not later. Fourth, there could be a flight from risk prompted by fear of a double dip recession or geopolitical risks, such as a military confrontation between the US/Israel and Iran. As in 2008, when such a rise in risk aversion was associated with a sharp appreciation of the dollar, as investors sought the safety of US Treasuries, this renewed risk aversion would trigger a dollar rally at a time when huge short dollar positions will have to be closed.

This unraveling may not occur for a while, as easy money and excessive global liquidity can push asset prices higher for a while. But the longer and bigger the carry trades and the larger the asset bubble, the bigger will be the ensuing asset bubble crash. The Fed and other policymakers seem unaware of the monster bubble they are creating. The longer they remain blind, the harder the markets will fall.

I'm sometimes slow on the uptake, but when I got to reason #1, underlined above, I got it. The penny dropped, as they say, and I didn't need to read further.

One of the advantages of not being in the upper percentile of America's asset-holders is that I can read about stuff like this and still sleep soundly.
I would be honored, as I have said before, to have a few billion at risk.
But that is not one of the problems on my list.
