Triffin dilemma

The Triffin dilemma or paradox is the conflict of economic interests that arises between short-term domestic and long-term international objectives for countries whose currencies serve as global reserve currencies. This dilemma was first identified in the 1960s by Belgian-American economist Robert Triffin, who pointed out that the country whose currency, being the global reserve currency, foreign nations wish to hold, must be willing to supply the world with an extra supply of its currency to fulfill world demand for these foreign exchange reserves, thus leading to a trade deficit.

The use of a national currency, such as the U.S. dollar, as global reserve currency leads to tension between its national and global monetary policy. This is reflected in fundamental imbalances in the balance of payments, specifically the current account, as some goals require an outflow of dollars from the United States, while others require an overall inflow.

Specifically, the Triffin dilemma is usually cited to articulate the problems with the role of the U.S. dollar as the reserve currency under the Bretton Woods system. John Maynard Keynes had anticipated this difficulty and had advocated the use of a global reserve currency called 'Bancor'. Currently the IMF's SDRs are the closest thing to the proposed Bancor but they have not been adopted widely enough to replace the dollar as the global reserve currency.

In the wake of the financial crisis of 2007–2008, the governor of the People's Bank of China explicitly named the reserve currency status of the US dollar as a contributing factor to global savings and investment imbalances that led to the crisis. As such the Triffin Dilemma is related to the Global Savings Glut hypothesis because the dollar's reserve currency role exacerbates the U.S. current account deficit due to heightened demand for dollars.


Onset during Bretton Woods era[edit]

Due to money flowing out of the country through the Marshall Plan, U.S. military budget and Americans buying foreign goods, the number of U.S. dollars in circulation exceeded the amount of gold that was backing them up in 1959.

By the autumn of 1960, an ounce of gold could be exchanged for $40 in the London market even though the official rate in the United States was $35. This difference showed that investors knew the dollar was overvalued.

The solution to the Triffin dilemma for the United States was to reduce dollars in circulation by cutting the deficit and raising interest rates to attract dollars back into the country. Some economists believed both these tactics, however, would drag the U.S. economy into recession.[citation needed]

In support of the Bretton Woods system and to exert control over the exchange rate of gold, the United States initiated the London Gold Pool and the General Agreements to Borrow (GAB) in 1961 which sustained the system until 1967, when runs on gold and the devaluation of the pound sterling were followed by the demise of the system.

The Balance of Payments dilemma[edit]

In order to maintain the Bretton Woods system, the U.S. had to run a balance of payments current account deficit to provide liquidity for the conversion of gold into U.S. dollars. With more U.S. dollars in the system the citizens began to speculate, thinking that the U.S. dollar was overvalued. This meant that the United States had less gold as people started converting U.S. dollars to gold and taking it offshore. With less gold in the country there was even more speculation that the U.S. dollar was overvalued. Furthermore, the US had to run a balance of payments current account surplus to maintain confidence in the U.S. dollar.

As a result, the United States was faced with a dilemma because it is not possible to run a balance of payments current account deficit and surplus at the same time.

The Nixon Shock[edit]

In August 1971, President Richard Nixon acknowledged the demise of the Bretton Woods system. He announced that the dollar could no longer be exchanged for gold, which soon became known as the Nixon shock. Although it was announced as a temporary measure, it was to remain in effect. The "gold window" was closed.

Implication in 2008 meltdown[edit]

In the wake of the financial crisis of 2007–2008, the governor of the People's Bank of China explicitly named the Triffin Dilemma as the root cause of the economic disorder, in a speech titled Reform the International Monetary System. Zhou Xiaochuan's speech of 29 March 2009 proposed strengthening existing global currency controls, through the IMF.[1][2]

This would involve a gradual move away from the U.S. dollar as a reserve currency and towards the use of IMF special drawing rights (SDRs) as a global reserve currency.

Zhou argued that part of the reason for the original Bretton Woods system breaking down was the refusal to adopt Keynes' bancor which would have been a special international reserve currency to be used instead of the dollar.

American economists such as Brad DeLong agreed that on almost every point where Keynes was overruled by the Americans during the Bretton Woods negotiations, he was later proved correct by events.[3]

Zhou's proposal attracted much international attention;[4] in a November 2009 article published in Foreign Affairs magazine, economist C. Fred Bergsten argued that Zhou's suggestion or a similar change to the International Monetary System would be in the best interests in both the United States and the rest of the world.[5] While Zhou's proposal has not yet been adopted, leaders meeting in April at the 2009 G-20 London summit agreed to allow 250 billion SDRs to be created by the IMF, to be distributed to all IMF members according to each country's voting rights.

On April 13, 2010, the Strategy, Policy and Review Department of the IMF published a comprehensive report examining these aforementioned problems as well as other world reserve currency considerations, recommending that the world adopt a global reserve currency (bancor) and that a global central bank be established to administer such a currency.[6] In this report, the current issues with having a national global reserve currency are addressed. The merits, difficulties and effectiveness of establishing a multi-currency reserve system are weighed against that of the SDRs, or "basket currency" strategy, and those of establishing this new "global reserve currency". A new multilateral framework and "multi-polar system" for managing capital flows and national debts is also called for, but the IMF cautions that it prefers a gradual shift to this new framework, rather than a sudden change.
