There is an extraordinary component of the global financial system that receives remarkably little attention. It involves tens of trillions of dollars in financial obligations that do not appear in conventional debt statistics, are not generally recorded as ordinary borrowing on corporate balance sheets and yet must be settled or refinanced when they fall due. These obligations exist within the foreign-exchange derivatives market, principally through foreign-exchange swaps, forwards and currency swaps. They are used every day by major international banks, pension funds, insurance companies, investment managers and multinational corporations.
According to the Bank for International Settlements, outstanding dollar-payment obligations associated with these instruments exceeded $80 trillion in its landmark 2022 analysis. To appreciate the magnitude of that figure, it was substantially larger than the entire annual output of the United States, China and the European Union combined. Yet most people have never heard of this hidden dollar debt system. Even many discussions of global financial stability concentrate on government debt, household borrowing, corporate leverage and bank lending while paying comparatively little attention to the enormous contractual payment obligations embedded in foreign-exchange derivatives.
The significance of this is not that $80 trillion is about to default. That would be a fundamental misunderstanding of how these instruments operate. Many transactions are hedged, matched or offset by corresponding assets and claims. The danger lies elsewhere in that the international financial system has developed an extraordinary dependence on the continuous availability of short-term dollar funding. Institutions across the world must repeatedly obtain, exchange and return dollars through a complex network of financial intermediaries. If that network becomes impaired, institutions that appear solvent can suddenly face acute liquidity shortages.
History tells us that this is not merely theoretical. The system experienced severe disruption during the 2008 financial crisis. It came under enormous pressure again in March 2020. On both occasions, central banks intervened to prevent dollar-funding markets from seizing up. The architecture of this hidden system is complex and enormous and its vulnerabilities can spread across international financial markets rapidly.
