- A stronger dollar makes dollar-priced commodities more expensive for buyers using other currencies, often putting downward pressure on oil and gold.
- Emerging markets face the compounding burden of rising import costs and higher servicing costs on dollar-denominated debt.
- US multinationals that earn revenue abroad see that income shrink in dollar terms, creating a drag on reported earnings.
When the dollar strengthens against other currencies, the effects ripple across commodity markets, emerging economies, and corporate balance sheets.
The mechanism is fairly straightforward.
More than half of global trade is invoiced in US dollars ⁽¹⁾, which means dollar movements translate directly into price changes for buyers and sellers operating in other currencies.
How Dollar Strength Moves Commodity Prices
Oil, gold, and most industrial metals are priced and traded in dollars. When the dollar strengthens, those commodities become more expensive for buyers holding euros, yen, or emerging market currencies.
That can weaken purchasing power for non-dollar buyers and often weighs on commodity demand when supply conditions are stable.
Gold reflects this dynamic clearly. Because gold is priced in dollars, a buyer in Japan or Brazil faces a higher effective price for the same ounce when the dollar rises.
But gold is also sensitive to interest rates and real yields. When dollar strength comes alongside higher US yields, gold can face a second headwind because it does not pay income. Cash and bonds become more attractive by comparison, reducing demand for non-yielding assets.
This is why gold can struggle when the dollar and Treasury yields rise together. The dollar makes gold more expensive for foreign buyers, while higher yields increase the opportunity cost of holding it.
The European Central Bank has documented this inverse relationship across the commodity complex, noting that dollar appreciation tends to suppress commodity prices through both the purchasing power channel and tighter global financial conditions. ⁽²⁾
The Emerging Market Squeeze
For emerging market economies, a strong dollar creates a compounding burden.
Many of these countries hold significant amounts of dollar-denominated debt. As the dollar strengthens, the cost of servicing that debt rises in local currency terms, even if interest rates remain unchanged.
At the same time, dollar-priced imports, particularly energy, become more expensive, putting pressure on current account balances and inflation.
Currency depreciation can also accelerate the problem. When local currencies weaken against the dollar, the real cost of dollar obligations increases further.
The 2014–16 period illustrated this mechanism clearly. During this time, as the dollar strengthened sharply, many commodity-exporting emerging markets faced simultaneous revenue compression and rising debt burdens.
For GCC economies, the dynamic differs because many regional currencies, including the UAE dirham, are pegged to the dollar.
A stronger dollar can support purchasing power for imports, but it also imports tighter US monetary policy and can affect non-oil sectors by making dollar-linked economies more expensive for visitors and trade partners using weaker currencies.
US Corporate Earnings Take a Hit
Dollar strength creates a headwind for US companies with significant international operations.
S&P 500 companies generate roughly 40% of their revenue outside the United States. ⁽³⁾ When that foreign revenue converts back into a stronger dollar, reported figures can shrink even when underlying demand is unchanged.
A sustained 10% rise in the dollar has historically reduced S&P 500 earnings per share by 2% to 4%. ⁽⁴⁾
The technology and consumer staples sectors carry the most exposure. Companies that sell globally but report in dollars face the greatest translation drag, with some major tech firms generating more than half their revenue overseas.
When the Relationship Breaks Down
The inverse link between dollar strength and commodity prices is not fixed.
Since the United States shifted from net oil importer to net oil exporter, higher commodity prices now tend to support rather than undermine the dollar’s terms of trade.
This structural change has weakened the historical negative correlation between the dollar and oil prices, with the two moving in the same direction during several periods since 2022.
Geopolitical supply shocks can further override the mechanism. Conflict-driven disruptions can push oil prices higher regardless of dollar direction, as markets demonstrated in 2022 following the Russian invasion of Ukraine.
