Summary:

On 9 June last, the Rafael del Pino Foundation hosted the dialogue "Past, present and future? in the reign of the dollar in the world".The International Monetary Fund's economist Kenneth Rogoff, professor at Harvard University and former chief economist of the International Monetary Fund, on the occasion of the publication of his latest book, "The World Bank and the International Monetary Fund: A New Approach to the World Economy". Our Dollar, Your Problem. He was accompanied by Joaquín Artés, Professor of Economics at the Complutense University of Madrid.

During the event, Rogoff reviewed seven decades of dollar hegemony as the dominant currency in global markets. While this position has brought the United States significant economic and political benefits - such as the ability to finance itself at lower cost or to impose effective financial sanctions - it has also created new vulnerabilities in an environment of increasing geopolitical and technological competition.

A historic rise... and its limits

Rogoff explained how the dollar established itself as the anchor currency of the international monetary system after World War II, especially during the Bretton Woods system. Although this regime collapsed in 1971 with the suspension of the dollar's convertibility into gold, the greenback maintained its centrality thanks to the strength of the US economy, its financial system and its military power.

However, the author argues that the dollar reached its zenith more than a decade ago. Since then, other powers - especially China and the eurozone - have gained ground. Expanding international trade, technological advances and Washington's geopolitical use of the financial system are progressively eroding the dollar's appeal.

Failed attempts at alternatives

The euro, the yen and the renminbi have been the most serious candidates to challenge the dollar's dominance, but all have faced limits. Rogoff pointed to key strategic mistakes, such as Greece's admission to the euro, prolonged deflation in Japan or excessive state control in China. Nevertheless, he noted that Europe could increase its monetary weight if it moves forward with fiscal integration and common defence, especially in the face of a possible second term for Donald Trump.

Towards a multipolar world in foreign exchange?

Rogoff argues that we are not facing an immediate replacement of the dollar, but a progressive diversification of the international monetary system. The rise of cryptocurrencies, the development of alternative payment systems (such as those promoted by China) and the digitalisation of money are driving this trend. In his opinion, this evolution is inevitable, although he warns of systemic risks if the new financial technologies are not adequately regulated.

The role of monetary policy

He recalled the importance of preserving the independence of central banks, an idea he himself helped to develop in the 1980s. In the face of political pressures to keep interest rates low, Rogoff argued that only a credible monetary authority can prevent inflation crises and loss of confidence in the currency.

What can come?

The economist concluded with a warning: while dollar hegemony has allowed the US to finance growing deficits without immediate consequences, this situation is not sustainable. "We don't know when the crisis will come, but when it does, it will be deep," he said. Countries tend to adjust their imbalances only after the collapse," he added.
