"Hot money poses risks to China’s stability"

One of the insufficiently-covered stories in the business press is the accelerating growth of China’s foreign exchange reserves. That information is treated as old hat. Yes, China has a big trade surplus so it has substantial FX reserves. Next?

But a new and volatile element has been added to the mix. The money coming into China isn’t just the result of a current account surplus or foreign investment. Substantial amounts of speculative capital have also flooded in. The danger is that even with an economy with massive FX reserves like China’s, large flows of hot money can be destabilizing. Michael Pettis and Brad Setser have been following this development with some concern on their respective blogs, but it hasn’t gotten much attention elsewhere.

That oversight is remedied today in a Financial Times comment by Michael Pettis and Logan Wright:

For many years China’s reserve accumulation was largely powered by its high and rising trade surplus and its status as the favourite destination for foreign direct investment. These are relatively stable sources of inflow and are even likely to be neutral or slightly countercyclical. But in recent months it has been no longer the trade surplus, in combination with FDI, that is powering the increase. The trade surplus is slightly down in 2008 compared with last year, as is the use of foreign-sourced funds for investment, even as the rate of Chinese reserve accumulation has doubled.

During the first halves of 2005 and 2006, the trade surplus, FDI and estimated interest on China’s reserves accounted for 80-90 per cent of the country’s reserve accumulation. In the first half of 2007, these components accounted for about 70 per cent. This year, however, their share has declined dramatically to 39 per cent from January to May (after we adjust China’s headline growth in reserves to account for a number of transactions that have in effect “outsourced” the job of reserve accumulation to other entities within China). Because there are likely to be speculative inflows buried in the trade and FDI accounts, their true share is probably even lower.

So what is powering China’s accelerating reserve accumulation? Probably hot money. As it becomes increasingly clear that China must revalue its currency sharply or else face surging inflation and the threat of financial instability, more and more investors, business people and ordinary households are bringing money into China to take advantage of profits associated with the expected appreciation or to protect themselves from the losses they will incur with the rising renminbi.

Consequently a flood of speculative money, amounting possibly to tens of billions of dollars every month, is pouring into China. There is no technical definition of hot money and of course, with much of it entering the country illegally, it is tough to measure, but it is possible to obtain rough proxies for speculative inflows and to track their change over time. In every case the proxy, however it has been derived, shows a startling increase over the past 12 months. The fact that in recent months the authorities have taken increasingly desperate measures to staunch the inflows confirms this interpretation of soaring hot money proxies.

If hot money is indeed increasing as quickly as the various proxies suggest, it indicates that not only is Chinese reserve accumulation going through a large quantitative change as it doubles yet again, it is going through an even more important qualitative change.

Hot money is notoriously unstable and even more notoriously procyclical. When the economy is growing, or even overheating, inflows are likely to increase net investment and add even more fuel to the economic engine. But when conditions change and the economy begins to slow or the country face financial risks, hot money is likely to flee the country, exacerbating the very conditions it is fleeing.

The Asian financial crisis steeled Chinese policymakers to create safeguards against capital flight, and China’s massive reserves and capital controls are likely to prevent a rapid speculative assault on the renminbi. However, just because China may be less vulnerable to an external financing crisis does not mean that authorities are out of the woods.

The increasing procyclicality of Chinese capital inflows could place the gradualist, consensus-driven Chinese leadership significantly behind the curve when the inflows reverse, when the government should be providing liquidity to the real economy rather than mopping it up. Under these conditions, the risks to the domestic banking system, rather than the currency, are likely to be more significant.

    Tom Malthus at seekingalpha.com takes a look at hot money flows in “China’s Impending Financial Crisis”. He points out a new twist –

    “‘hot money’ that may be hidden within the sector (i.e. through over-invoicing). Some estimates have placed the amount of hot money hidden within the sector at around 2% of exports.”

    He also projects forward to when the appreciation of the yuan might turn to depreciation to reverse the flow of hot money.

    Last week I came over from The Dark side and thought those cunning folks in China were smart to be obtaining cheap US dollars, because it was likely that oil would fall and the buck would spike, however, with all these banks going down, and Fannie, freddie and this systemic re-engineering, I’m back to the Dark Side and think the dollar will eat these poor people alive and that the old bet is off and they are holding trash in what amounts to a liquidity trap! Oil will spike and the buck will crash!
