First posted 17 November 2008, this column's analysis is more relevant than ever. It asks why investors rush to government securities when the US was at the epicentre of the financial crisis? This column attributes the paradox to key emerging market economies’ exchange practices, which require reserves most often invested in US government securities. America’s exorbitant privilege comes with a cost and a responsibility that US policy makers should bear in mind as they address financial reform.
- Act One: Unbounded Enthusiasm. Some markets find favour with global investors. Credit becomes readily available, asset prices percolate, and many categories of spending are buoyed.
- Act Two: Day of Reckoning. Recognition that some of that enthusiasm was overdone spreads among investors. New credit flows cease, collateral is sought, asset prices crash, and prominent private-sector icons crumble.
- Act Three: Restoration. Here governments pick up the pieces, typically passing on the cost to future generations by issuing a vast volume of debt. The cost can be punishing because investors pull away from the governments of emerging market economies as forcefully as they do from private creditors.
But there has been one prominent exception to this classic tale. With fitting irony, the US, which is the epicentre of the crisis, has avoided Act Three. The US enjoyed a capital inflow bonanza that funded yawning current account deficits, and asset prices spiralled upward only to crash. While the crash has constricted credit and is redrawing the financial landscape, the US has not been punished by investors in typical Act-Three fashion.
If this had happened to any other government in the world whose national financial institutions were in as deep disarray as those of the US, investors would have run for the hills – cutting off the offending nation from global capital markets. But for the US, just the opposite has happened.
Rather than facing prohibitive costs of raising funds, US Treasury Bills have seen yields fall in absolute terms and markedly in relative terms to the yields on private instruments. This has been called a “flight to safety”. But why do global investors rush into a burning building at the first sign of smoke?
The answer lies in part with the exchange market practices of key emerging market economies.
Since the last global market panic, the Asian Financial Crisis of 1998, many governments have stockpiled dollars in their attempts to prevent their exchange rates from appreciating. At the same time, the long upsurge in commodity prices has swollen the coffers of many resource-rich nations. As a result, and as shown in the latest forecast in the World Economic Outlook of the International Monetary Fund, international reserves of emerging market economies are expected to have increased $3.25 trillion in the last three years. According to the Fund’s survey of the currency composition of those holdings, the bulk is in dollars (see Figure 1).
The dollar portion of these reserves is most often invested in US government securities, which offers excellent market liquidity, and US government debt is also considered as safe as anything (following a precedent laid down by the first Secretary of the Treasury, Alexander Hamilton). All this explains the dollar’s popularity with foreign investors who might otherwise be expected to shun the US. As the Figure 2 indicates, foreign official entities now own almost one-quarter of outstanding government securities (the upper panel). These holdings of securities constitute about 10% of non-US nominal GDP (the lower panel).
Our currency, your problem
Herein lies the special status of US government securities. For a few of the world’s key decision makers, it is not in their economic interest to stop, or even slow, the purchase of Treasury Bills. As Keynes once said: “If you owe your bank a hundred pounds, you have a problem. But if you owe a million, the bank has a problem.” Potential capital losses on existing stocks keep foreign investors locked into US government securities.
Figure 2 also shows a precedent for recent financial market strains. The last time foreign official purchases bulked so large in the US government’s financing was from 1968 to 1973, when the Bretton Woods system of managed exchange rates broke down.5 At that time, keeping the system going required increasing support from abroad, primarily from Europe. This time around, the source of that support has shifted to Asian-Pacific economies and Middle East exporters. In both cases, the message from the US seems best summarised in the words of then-Treasury-Secretary John Connolly, who famously advised, “the dollar is our currency, but your problem.”
As the tone of those words suggests, another lesson from the earlier experience is that foreign resentment with a US-dominated arrangement grows over time. That America could be a source of financial instability and a haven of sovereign financial security seems to some, to quote Valerie Giscard d'Estaing, to be an “exorbitant privilege.”
In this episode, Treasury yields have fallen and the foreign exchange value of the dollar has appreciated recently. Moreover, many European financial firms have had funding difficulties associated with a lack of access to dollar liquidity. This has made it necessary for European officials, caps in hands, to seek swap arrangements with the Federal Reserve to acquire dollars to re-lend to their national champions.
Recent enthusiasm in Europe for fundamental reform of the international monetary system finds its roots, in part, in this resentment. They do not want our dollar to be their problem, and they want to erode some of that privilege. Put it those terms, however, it seems clear that this will mostly be a one-way conversation. US officials must recognise that their nation’s funding advantage rests on the unrivalled, for now, position of US government securities in global financial markets. Thus, they will listen and agree to work-streams for groups to report back in the future. But whether it is this Administration or the next, advantages to the US,
