Trump Tariffs and Currency Impact — What It Means for Your Money

The Trump administration's second-term tariff offensive has sent shockwaves through global currency markets. With tariffs of up to 145% on Chinese goods and baseline 10–25% levies on major trading partners including South Korea, the US dollar has surged while emerging market currencies have taken a beating. For anyone holding Korean won or watching their household expenses climb, understanding what is happening and why matters right now.

The Mechanics: Why Tariffs Strengthen the Dollar

When the US imposes tariffs on imported goods, several things happen in sequence. First, US demand for foreign goods falls, which reduces the need for foreign currency in trade transactions. Less demand for Korean won, for instance, pushes the won lower against the dollar. Second, trade war uncertainty triggers what markets call risk-off behavior: global investors exit volatile assets and pile into the dollar and US treasuries as safe havens. Third, retaliatory tariffs from other countries tend to hurt export-dependent economies more than the US, amplifying their currency weakness.

The result is a reinforcing cycle. Dollar strength means import costs rise in tariff-targeted countries, which feeds inflation, which forces central banks into difficult choices between cutting rates (to support growth) and holding rates (to defend the currency).

Dollar strength during trade disputes is not accidental. It follows a predictable pattern: tariffs reduce trade flows, risk-off sentiment floods capital into dollars, and export-dependent economies feel the squeeze.

What the Numbers Look Like

The Korean won has moved from around 1,300 KRW per dollar in early 2025 to above 1,450 KRW following the escalation of tariff measures. That is a depreciation of roughly 11% in just over a year. For households and businesses, this translates directly into higher costs on anything that touches the dollar.

Item	At 1,300 KRW/$	At 1,450 KRW/$	Difference
$500 online purchase	650,000 KRW	725,000 KRW	+75,000 KRW
$2,000/month overseas transfer	2,600,000 KRW	2,900,000 KRW	+300,000 KRW
Imported goods (per $1,000 CIF)	1,300,000 KRW	1,450,000 KRW	+150,000 KRW

Which Assets Tend to Hold Up During Dollar Strength

Not every asset suffers when the dollar rises. Understanding the landscape helps you position better rather than just reacting to fear.

Dollar-denominated assets: US equities, dollar deposits, and dollar money market funds all benefit from a stronger dollar when measured in won terms. An S&P 500 index fund bought in won gains both from stock price movement and from currency appreciation.

Gold: The relationship between the dollar and gold is complicated. Historically the two move inversely, but during periods of geopolitical and economic uncertainty both can rise simultaneously. Gold serves as a hedge against the broader instability that tariff wars create, not just against dollar strength specifically.

Korean export companies: Counterintuitively, a weaker won can benefit large Korean exporters. Samsung, Hyundai, and SK Hynix earn revenue in dollars but report earnings in won. A higher won/dollar rate means their overseas revenues convert into more won on paper. However, if tariffs directly reduce their export volumes, this theoretical advantage gets offset.

Practical Steps — What to Actually Do

Financial stress during currency volatility often leads people to make reactive decisions that hurt them later. Here is a measured approach.

1. Check your dollar exposure: If you have zero dollar-denominated assets, consider building a small position gradually. A target of 20–30% of liquid savings in dollar assets is a reasonable buffer for most households.
2. Dollar-cost average, do not chase: Buying large amounts of dollars at peak exchange rates is speculation. Set up a regular automatic exchange of a fixed won amount monthly. This smooths out your average cost over time.
3. Reduce discretionary USD spending: Overseas travel and large foreign purchases cost more when the won is weak. Deferring non-essential dollar spending until the rate improves is practical money management, not paranoia.
4. Keep a close eye on your import exposure: Businesses that buy raw materials priced in dollars are directly exposed. Review supplier contracts and consider whether hedging instruments make sense at your scale.

What History Suggests About the Endgame

The first Trump trade war, from 2018 to 2019, followed a clear arc. Tariffs escalated, markets panicked, currencies in trade-deficit countries weakened, and then a Phase 1 deal with China stabilized the situation. The won recovered much of its losses within months of the deal announcement.

That does not guarantee the same outcome this time. The second-term tariffs are broader, higher, and accompanied by more explicit industrial policy goals. But the fundamental constraint remains: American consumers pay for tariffs through higher prices, and political pressure to ease those conditions has not disappeared. Negotiations and gradual unwinding are a realistic scenario, not a wishful one.

The practical takeaway is that extreme positioning in either direction — going all-in on dollars at peak rates or ignoring the issue entirely — carries unnecessary risk. Steady diversification and a long view tend to outperform both panic and complacency.
