What Happens if the Dollar Loses Its Grip on Global Trade

Kenya, April 06, 2026 - There is a quiet assumption that underpins almost everything in the global economy today: that the US dollar will always be at the center of it. It is the currency of trade, of debt, of reserves, of markets. From oil shipments to online trading platforms, from government borrowing to cryptocurrency benchmarks, the dollar sits at the core. But that dominance did not happen by accident. It was built, slowly, strategically, on something as simple, and as powerful, as oil.

How oil built the modern financial system#

At the heart of the global economy is a system most people never fully see: the petrodollar. Since the 1970s, oil has been priced almost exclusively in US dollars. That single decision created a chain reaction that reshaped global finance. If a country wants to buy oil, it must first acquire dollars. That requirement forces central banks to hold dollar reserves, pushes governments to earn dollars through exports, and compels financial systems to operate around dollar liquidity. Over time, this did something profound.

It made the dollar not just a currency, but the default language of global trade. Today, nearly 80 percent of global trade transactions involve the US dollar, and about 60 percent of global foreign exchange reserves are held in dollars. Even markets that appear independent, like cryptocurrency, are still largely benchmarked against dollar-pegged assets such as USDT. So when we talk about the petrodollar, we are not just talking about oil. We are talking about the foundation of the modern economic system.

Why countries like Kenya must “chase dollars.”#

For countries like Kenya, Ethiopia, or other East African Countries, this system creates a structural imbalance. These economies earn in local currencies, but operate globally in dollars. They import fuel in dollars. Service external debt in dollars. Price exports in dollars. This creates constant pressure to acquire and maintain dollar reserves. When the dollar strengthens, everything tightens.

Imports become more expensive. Inflation rises. Debt servicing costs increase. And central banks are forced to intervene, often at the expense of growth. This is not just market behavior. It is the architecture of dependency.

Even digital markets are not “free” from the dollar#

There is a common belief that new financial systems, especially crypto, exist outside traditional structures. They do not. Most cryptocurrency trading globally is still conducted through dollar-linked stablecoins. Foreign exchange markets are built around dollar pairs. 

International payments systems, from SWIFT to correspondent banking, are deeply dollar-centric. In other words, even when the system looks decentralised, the dollar remains embedded within it.

So what happens if the system begins to shift?#

This is where the conversation moves from theory to reality. The rise of alternative trade blocs like BRICS, combined with geopolitical tensions and energy disruptions, is beginning to test the system. Countries are experimenting with non-dollar trade:

China buying energy in yuan
India settling some trade in rupees
Russia bypassing Western financial systems altogether

These are not isolated moves.

They are early signs of a structural shift.

If the petrodollar weakens, the world does not collapse, but it changes#

The most important thing to understand is this: the dollar will not disappear. But it may no longer dominate. Even a partial shift, where 20 to 30 percent of global trade moves into alternative currencies, would fundamentally alter the system.

Global trade would become multi-currency.
Financial power would become more distributed.
Markets would become more fragmented, and less predictable.

For the United States, the consequences would be significant. The country currently carries over $34 trillion in national debt, sustained in part by global demand for dollar assets. If that demand weakens, borrowing becomes more expensive, and the financial flexibility the US has long enjoyed begins to tighten.
