The Global Financial System
The Global Financial System
The global financial system is a web of institutions, currencies, agreements, and power relationships that determines which countries can borrow cheaply, which currencies hold value, and whose economic decisions affect everyone else's daily life.
The Key Institutions
The International Monetary Fund (IMF): Created in 1944, the IMF acts as the global lender of last resort. Countries facing currency crises or debt crises can borrow from the IMF. The catch: IMF loans come with conditions — policy changes the country must implement. These conditions are frequently criticized as prioritizing repayment to creditors over the welfare of ordinary citizens in borrowing countries. Jamaica has had extensive dealings with the IMF, with programs spanning decades.
The World Bank: Also created in 1944, the World Bank lends to developing countries for infrastructure and development projects. It has two main arms: the IBRD (International Bank for Reconstruction and Development), which lends to middle-income countries at near-market rates, and the IDA (International Development Association), which provides grants and zero-interest loans to the poorest countries.
The Bank for International Settlements (BIS): The central bank for central banks. The BIS facilitates cooperation among the world's central banks, provides banking services to central banks, and conducts research on global monetary stability. When central bank governors from major economies want to coordinate, the BIS is the venue.
Why the US Dollar Rules
After World War II, the US was the world's dominant economic power with the only major economy whose industrial capacity was intact. The dollar became the world's reserve currency — the currency that other countries hold as savings and use to settle international trade.
This status creates what former French President Valéry Giscard d'Estaing called America's "exorbitant privilege." Because global demand for dollars is permanently high (everyone needs them for trade), the US can borrow at lower interest rates than any other country. It can also finance deficits more easily because other nations absorb dollars as reserves.
The practical consequence: when the US Federal Reserve raises interest rates, dollars become more attractive globally. Capital flows from emerging markets to US assets. Emerging market currencies weaken. Countries with dollar-denominated debt find that debt harder to service. A decision made by the Fed in Washington directly affects the cost of living in Jamaica, Ghana, and Argentina.
How This Affects Small Economies Like Jamaica
Jamaica's economy operates in the shadow of these global structures:
- Jamaica's foreign exchange reserves are largely held in US dollars
- Jamaica's major exports (tourism, remittances, bauxite) are priced in US dollars
- When the USD strengthens (which happens when the Fed raises rates), Jamaica's import costs rise because imported goods become more expensive in JMD terms
- Jamaica must maintain sufficient dollar reserves to defend the JMD exchange rate
The 2022-2023 US rate hike cycle drove dollar strengthening globally. Countries with large dollar-denominated debts — including many in the Caribbean and Latin America — faced painful currency depreciation and higher debt service costs, entirely as a consequence of US monetary policy decisions made for US domestic inflation concerns.
The Current Order and Its Challengers
The US dollar's dominance is not permanent. China has been steadily internationalizing the yuan (RMB), creating alternative payment systems (CIPS) to compete with the SWIFT system that runs dollar-based international transfers. The BRICS bloc has discussed creating a common currency for trade settlement among member nations.
Whether any of these developments dethrone the dollar is uncertain — the dollar benefits from a self-reinforcing network effect: it is used because it is trusted, and it is trusted because it is used. But the direction of travel is toward a more multipolar currency world, where the US has less unilateral financial leverage than it has had since 1945.
