The US dollar is more than just the currency of the world’s largest economy. It sits at the centre of global trade, debt and investment — and its movements can influence markets across continents.
A dominant force in international reserves
Over 60% of all foreign exchange reserves held by central banks are denominated in US dollars. The dollar’s status as the global reserve currency means it is the backbone of financial systems from Asia to South America.
Countries hold large quantities of dollars to manage currency stability, service dollar-denominated debt, and settle international transactions. This demand creates a unique position of strength, giving the US influence beyond its domestic economy.
Pricing power in commodities and trade
Most globally traded commodities — including oil, gold and wheat — are priced in US dollars. This makes the dollar’s value a critical factor in determining the cost of goods worldwide.
When the dollar strengthens, commodities typically become more expensive for non-dollar holders, which can dampen demand. A weaker dollar, by contrast, supports commodity prices and can provide a tailwind for exporters in dollar-linked markets.
This pricing mechanism also affects trade balances. Countries with weaker currencies relative to the dollar often face rising import costs, contributing to inflation and altering monetary policy decisions.
Impact on emerging markets and capital flows
Many emerging markets borrow in US dollars because of the dollar’s stability and liquidity. But this creates vulnerability. When the dollar rises, local-currency debt becomes harder to repay, and investors may pull back from emerging market exposure.
Capital often flows back into dollar-denominated assets during periods of strength, particularly into US Treasuries and money market funds. This reinforces the cycle and affects yields and risk appetite elsewhere.
Safe haven in times of crisis
The dollar consistently attracts capital during moments of global stress. Whether it’s a financial crisis, a geopolitical shock or market uncertainty, the dollar is viewed as a stable store of value.
This safe haven dynamic can push the dollar higher even when US fundamentals are under pressure, as investors favour liquidity and security over yield.
What investors need to consider
Movements in the dollar can impact everything from equity and bond returns to inflation and commodity prices. For investors with international exposure, it’s not just a background factor — it’s a central theme that shapes portfolio performance.
