FX Reserves - the real drivers of diversification
I had an opinion piece on China’s FX reserves in the WSJ China on Monday. Chinese readers can see the original here. For everyone else, the English version is below:
The Real Drivers of Diversification in China’s FX Reserves
Where is China hiding its USD2.5trln in foreign exchange reserves? The answer to that question is one of the best kept secrets in the world of finance. The State Administration of Foreign Exchange (SAFE) - the organisation charged with the management of the USD2.5trln - certainly isn’t telling anyone, and for good reason. When you are moving around the kind of money that SAFE is moving around, telegraphing intentions to the market can make everything you want to buy terribly expensive and everything you want to sell awfully cheap.
But in the absence of real information, rumours proliferate, and sometimes fire the imagination of the markets. This is one of those times. First, at the end of May, came reports that SAFE was growing tired of the ups and downs of the euro, and reconsidering its holdings of European debt. Those rumours were enough to send the euro plunging 1.5% against the dollar over the course of a single day’s trading. A denial from SAFE calmed the markets. But a few weeks later, rumours from Tokyo suggested that, despite its protestations to the contrary, SAFE was indeed growing weary of the euro, and was switching to Japanese government debt, with purchases of USD6.3bln over the first four months of the year. The next week, another rumour, this time suggesting that SAFE was back in the euro game, with a purchase of E400mln (USD516mln) in 10-year Spanish bonds.
Japanese bonds one week, Spanish bonds the next, if the press is to be believed, China is buying anything but US Treasury debt. But what have we really learned from the claims and counterclaims of the last few weeks? Not a lot that we did not know already. If China’s FX reserves are allocated in roughly the same proportions as global FX reserves as a whole - a reasonable assumption - then around 61% should be parked in dollar debt, with 27% in euro debt, 3% in yen, and the rest invested in other currencies. That means that SAFE has something like USD675bln in euros, and a smaller but still sizeable USD75bln in yen. In this context, the purchase of a few million in Spanish bonds and a few billion in Japanese government debt can hardly be regarded as anything other than business as usual.
A continued focus on dollar debt by China’s FX managers should come as no surprise. Advocates of greater diversification point to risks to the value of China’s FX reserves from an excessive concentration in US Treasury debt. Fair enough. Inflation in the US, or a depreciation of the greenback, would both impact the purchasing power of China’s dollars. But value is only one consideration, and not the main consideration, in the allocation of China’s FX reserves. The fundamental reason for the allocation of China’s FX reserves to dollar debt is Beijing’s decision to manage the exchange rate against the dollar. As long as China wishes to continue running a massive trade surplus with the US, whilst holding the yuan stable against the dollar, the brutal logic of supply and demand in foreign exchange markets dictates that every cent of that trade surplus be recycled into dollars.
But the management of the exchange rate and the decision on where to invest FX reserves is a two step process. SAFE might have to buy dollars in the first step - to manage the exchange rate, but once it has those dollars could SAFE not declare ‘mission accomplished’ and use them to buy European or Japanese government debt? Not really. Let’s take diversification into European debt as an example. Use of dollars purchased in the FX market to purchase euro debt would weaken the dollar against the euro. As the yuan is managed with reference to the dollar, that also means that the yuan would weaken against the euro. That implies a reallocation of some of China’s trade surplus from the fast growing and dynamic US to a sclerotic EU. As the current European sovereign debt crisis makes clear, the old world’s capacity to live beyond its means is substantially less than that of the new.
The choice on the allocation of China’s FX reserves is not simply dictated by SAFE’s much repeated commitment to the principles of safety, liquidity, and returns. It is also dictated by China’s choice of exchange rate regime. It is not the micro-level investment plays but the macro-level economic policies that determine the allocation of China’s FX reserves. Chasing after rumours from London bankers or Japanese bureaucrats - sources that have their own self interested axes to grind - will not bring us any closer to the truth. But careful attention to shifts in China’s exchange rate policy just might.
The announcement by the People’s Bank of China (PBOC) of a shift to a more flexible exchange rate, set with reference to a basket of currencies, has far reaching implications for the growth and allocation of China’s FX reserves. First, on the growth of reserves, appreciation of just 0.7% against the dollar in the month since reforms were announced is unimpressive. But over time, a stronger yuan will be one of the factors changing the balance between China’s imports and exports, and reducing the size of the trade surplus. At the same time, two way movement in the yuan dollar exchange rate will reduce the incentive for currency speculators to dodge China’s capital controls, and hot money inflows should also be reduced. This does not necessarily have any implications for the way reserves are allocated. But a smaller trade surplus and reduced capital inflows will slow down the growth of China’s FX reserves and reduce SAFE’s budget for Treasury purchases. The US Treasury got a taste of what that might look like in May this year, when capital outflows contributed to a substantial fall in the value of China’s FX reserves, and China’s holdings of US Treasuries fell by USD32.5bln.
On the allocation of reserves, a more flexible exchange rate will also break the mechanical link which requires SAFE to recycle the trade surplus into dollars, and constrains their choice of where to park those dollars once they have bought them. That means Beijing can push forward with another innovation: the privatisation of China’s FX reserves. The first move in this direction, a shift in policy to allow Chinese firms to retain a portion of their overseas earnings, was announced quietly and without fanfare in 2009. This might seem like a minor technical change, but it signals something rather significant: the end of SAFE’s monopoly control of China’s FX reserves. The intention is to shift toward something like the Japanese system - where only a fraction of FX reserves are held by the government and the majority are in private hands. This is a transition that will happen over time, but the bottom line is less cash for SAFE to buy Treasuries and more funds for Chinese companies to make foreign acquisitions. The Chinese government might end up with a smaller share of the US public debt, but Chinese companies will end up with a bigger share of the Fortune 500. Diversification of China’s FX reserves is happening, but it is these structural shifts, not this or that investment decision by SAFE’s money managers, that are the real drivers.
