The dollar’s surge is squeezing emerging economies
The US dollar is doing more than making American exports cheaper. Its strength is reducing the purchasing power of currencies across Asia, Africa and Latin America, raising the local cost of food, fuel, medicine and machinery. Governments are also finding it harder to service debt issued in dollars.
How the US dollar’s strength is hurting emerging market economies is particularly dangerous for countries with limited foreign-exchange reserves. A currency that falls 20 per cent against the greenback can turn a manageable dollar obligation into a crushing domestic burden within months.
The damage is uneven. Oil importers and heavily indebted nations face immediate pressure, while countries with strong export earnings have more room to adjust. Even commodity producers can suffer when dollar-denominated prices fall faster than their costs.
For Australia, the issue is familiar but increasingly relevant. The country’s iron ore, coal and LNG contracts are generally priced in US dollars, while wages and operating costs are paid in Australian dollars. A strong greenback can therefore squeeze exporters while lifting the price of imported goods in Sydney and Melbourne.
The pressure runs through several channels
The dollar affects emerging economies through several connected channels, from import bills to investment flows.
| Economic channel | Under a stronger dollar | Under a weaker dollar |
|---|---|---|
| Imported fuel and food | Costs rise in local currency | Costs ease in local currency |
| Dollar-denominated debt | Repayments become more expensive | Debt burdens fall |
| Commodity exports | Foreign earnings lose value in local terms | Export income gains purchasing power |
| Capital investment | Investors seek higher returns or exit | Funding becomes cheaper |
| Local borrowing | Central banks may raise rates to support the currency | More room exists to reduce borrowing costs |
A weaker local currency also makes exports more competitive, but that advantage arrives after companies have already paid wages, electricity and transport bills in the damaged currency. For a small manufacturer, cheaper imported inputs may not compensate for lost domestic demand.
The adjustment is especially painful when inflation is already high. Higher fuel and food costs force central banks to raise interest rates, while weaker currencies encourage imports because they appear cheaper to consumers. That creates a cycle in which the currency keeps sliding and the cost of essentials keeps climbing.
Why US policy pushes the dollar higher
The dollar’s strength reflects the relative attractiveness of US assets. Federal Reserve interest rates remain elevated compared with many other major central banks, giving investors a reason to hold Treasury securities and US equities rather than riskier assets in developing markets.
Washington’s policy choices can reinforce that pull. Tariffs, tax cuts and tighter immigration rules can increase inflation or government borrowing, depending on their size and design. Higher inflation may keep US yields elevated, while larger deficits increase the supply of Treasury bonds competing for global savings.
During periods of geopolitical uncertainty, the dollar also gains value because governments and companies need a currency that can be used broadly for trade, reserves and emergency funding. That role gives it an advantage even when investors have concerns about US politics or public debt.
Dollar debt magnifies currency losses
Governments that borrow in dollars face a direct exchange-rate cost. If their local currency weakens, they need more of that currency to make the same repayments. The effect feeds back into financial markets because investors interpret the larger debt burden as a greater risk of default.
Central banks then face an uncomfortable choice. Raising rates can defend the currency and reduce inflation, but it also increases interest payments and makes mortgages and business loans harder to service. Countries such as India, Indonesia, Brazil and South Africa have used reserves and interest-rate adjustments to limit the damage, though each approach carries economic costs.
The private sector can be just as vulnerable. Airlines, energy companies and infrastructure firms often have dollar loans or dollar-linked leases. A depreciation can therefore weaken banks, businesses and household spending at the same time, turning a currency move into a broader economic slowdown.
Commodity exporters lose in local-currency terms
Many emerging economies depend on commodities, but dollar strength can reduce the income they receive from those exports. When oil, grain or metal prices are quoted in dollars and the local currency weakens, producers earn less in domestic purchasing power even if global prices remain unchanged.
Australia provides a clear example. Mining companies receive US dollars for iron ore, coal and LNG, while much of their expenditure is in Australian dollars. A weaker Australian dollar raises the local cost of fuel, equipment and labour, placing pressure on margins and government royalties. It can also reduce the value of commodity investment pipelines.
The impact reaches households through imported vehicles, electronics, clothing and energy. Aussie consumers may notice higher supermarket prices and more expensive online purchases from overseas. Businesses in Melbourne and Sydney face similar pressure when machinery, components or business software must be paid for in dollars.
Oil-importing Asian economies experience the reverse problem. A strong dollar increases their fuel bills while reducing the local-currency value of exports. The result can be a deterioration in trade balances, higher transport costs and greater dependence on foreign borrowing.
Capital flows can reverse sharply
The dollar often attracts money from emerging markets when US yields rise. Investors sell currencies such as the Indonesian rupiah, Mexican peso or South African rand and buy safer assets, temporarily forcing those currencies lower and raising their domestic borrowing costs.
Those reversals can be abrupt. A global risk-off episode may overwhelm improvements in a country’s trade balance or industrial output. Economies that borrowed heavily to finance relatively high interest rates can then struggle when international lenders become less willing to roll over their debts.
Foreign-exchange reserves provide a buffer, but they are not unlimited. Spending reserves to support a currency can reassure markets, while higher rates may be required when investors are already demanding unusually large returns. Countries with sound banks and flexible exchange rates generally have more room to adjust than those reliant on short-term foreign funding.
Governments have fewer easy options
One response is to sell reserves and buy domestic currency. This can smooth volatility, but repeated intervention drains the reserves needed for imports and external debt payments. Another is to tighten monetary policy, accepting weaker growth and higher unemployment in an attempt to restore confidence.
Fiscal measures can cushion households by limiting price increases or protecting vulnerable households from essential costs. Such programmes are expensive, however, and become harder to finance when investors are charging a premium on government debt. Austerity can reduce that pressure while worsening the effects on businesses and families already facing weaker demand.
Some countries are turning to longer-term measures, including issuing more debt in local currency, seeking currency swaps and building stronger regional payment arrangements. These steps reduce future exposure, yet they do little to repair balances that have already deteriorated during a dollar surge.
What this means for Australia
Australia’s commodity exposure and high household debt make exchange-rate movements especially important. The Australian dollar often carries more risk than the US dollar because it is linked to Chinese demand, commodity prices and domestic interest-rate expectations. It can strengthen during global liquidity swings, but it can also weaken when China slows or investors move into US assets.
The Reserve Bank of Australia must balance competing pressures. Supporting the currency through higher rates may restrain imported inflation, yet rate-sensitive mortgage and business-loan costs can quickly affect household spending. Lowering rates too soon could weaken confidence and expose the economy to a sharper slowdown.
Australian investors and policymakers should watch the Federal Reserve’s rate decisions, Chinese industrial activity, commodity prices and the dollar’s direction against the Australian dollar. A sustained US lead in interest rates would keep pressure on emerging markets, while a gradual US easing cycle would offer relief without guaranteeing a return to the low-rate environment that preceded recent volatility.
