- The Supreme Court ruled on 20 February 2026 (Learning Resources v. Trump, 6–3) that IEEPA does not authorise tariffs — the reciprocal and fentanyl tariffs fell and refunds followed
- A 10% Section 122 global tariff replaced them for 150 days and expired on 24 July 2026; new Section 301 tariffs of 10% or 12.5% on imports from 60 economies followed
- The realised average effective tariff rate was 2.3% in January 2025 and 6.7% in July 2026 (Penn Wharton) — far below the 17–19% some 2026 commentary claimed
- In April 2025 the dollar fell after the Liberation Day tariffs rather than rallying — tariffs do not reliably strengthen the USD
- No gold-specific tariff driver is verified in 2026; gold near $4,125 is trading on oil, the Fed's 16 September hike and 10-year yields near 5.2%

Are Tariffs Still the Main Macro Driver in 2026?#
Short Answer
No. Tariffs dominated FX headlines in 2025, but in 2026 the tariff regime de-escalated: the Supreme Court struck down the IEEPA tariffs on 20 February, and the realised effective tariff rate fell to 6.7% by July (Penn Wharton). Since late February the dominant macro story has been the US–Iran conflict, oil near $106–107, re-accelerating inflation and the Fed's 16 September rate hike.
Detailed Explanation
Earlier versions of this article claimed an effective tariff rate of 17–19% in Q2 2026 and called tariffs “the single biggest macro driver of 2026”. Neither holds up. Independent estimates show:
- Yale Budget Lab (21 February 2026): consumers faced an average effective tariff rate of about 16% before the ruling — the highest since 1936. It fell to 9.1% immediately after the ruling and rose to 13.7% once the Section 122 tariff was imposed.
- Penn Wharton Budget Model (9 September 2026): the realised average effective tariff rate, measured from customs data, was 2.3% in January 2025 and 6.7% in July 2026.
The two measures differ (statutory versus realised after importers change what they buy), but both show a lower tariff burden in mid-2026 than in 2025.
Example
A trader who in May 2026 positioned for “tariffs keep rising, so gold keeps rising” was wrong on both counts: the tariff burden fell, and gold's direction since January has been down — from about $5,589 to about $4,125.
Common Mistake
Assuming a 2025 theme still drives the market in 2026 without checking the latest legal and policy changes.
Professional Tip
Rank macro drivers every month. In September 2026 the order for USD pairs and gold was roughly: Fed path and yields, then oil and geopolitics, then tariffs.
Verified Tariff Timeline (2025–2026)#
Short Answer
The key steps were the IEEPA tariffs of 2025, the April 2025 “Liberation Day” announcement, the Section 232 metals tariffs, the 20 February 2026 Supreme Court ruling, the temporary Section 122 tariff, and the Section 301 tariffs that replaced it in July 2026.
Detailed Explanation
| Date | Action | Legal basis |
|---|---|---|
| Feb–Mar 2025 | Tariffs on Canada, Mexico and China announced; 25% on Canada and Mexico took effect in March with USMCA-compliant goods later exempted | IEEPA |
| 2 Apr 2025 | “Liberation Day”: 10% baseline tariff on most imports plus higher country-specific rates (most paused for 90 days a week later) | IEEPA |
| Apr–May 2025 | US tariffs on China escalated to 145% in April, then cut to 30% for 90 days after the May Geneva talks | IEEPA |
| Jun–Aug 2025 | Steel and aluminium tariffs raised to 50%; 50% tariff on copper; new country rates in August (e.g. India 50%, Brazil 50%, Switzerland 39%) | Section 232 / IEEPA |
| May–Aug 2025 | Court of International Trade and the Federal Circuit rule against the IEEPA tariffs; the case goes to the Supreme Court | Litigation |
| 20 Feb 2026 | Supreme Court, Learning Resources, Inc. v. Trump, 6–3: IEEPA does not authorise tariffs | Supreme Court |
| Feb 2026 | 10% global tariff for up to 150 days, with a rise to 15% announced; Section 232 goods and USMCA-compliant goods excluded | Section 122 |
| 24 Jul 2026 | Section 122 tariff expires; replaced by tariffs of 10% or 12.5% on imports from 60 economies | Section 301 |
IEEPA duties became refundable after the ruling; CBP had certified about $107bn of refunds by 21 August 2026, around 64% of the roughly $166bn collected (Penn Wharton, citing court filings).
Example
Because Section 232 tariffs (steel, aluminium, copper) rest on a different statute, they were not affected by the IEEPA ruling. A trader watching metals-sensitive currencies such as CAD needed to separate the two legal tracks.
Common Mistake
Treating all tariffs as one policy. Different statutes have different legal risks, durations and exemptions.
Professional Tip
Keep the USTR and CBP notice pages in your news feed. Tariff changes frequently arrive outside scheduled economic-calendar slots.
How Tariffs Can Move Currencies (4 Channels)#
Short Answer
Tariffs can move FX through risk sentiment, interest-rate expectations, retaliation against specific partners and long-run confidence in the dollar. Which one dominates varies, so the dollar's direction is not fixed.
Detailed Explanation
- Risk sentiment (minutes to days): surprise tariffs can trigger risk-off moves into perceived havens. But the dollar is not always the haven — in April 2025 US assets were sold together.
- Rates (days to weeks): tariffs raise import prices, which can lift inflation expectations and delay Fed easing, supporting the dollar against lower-yielding currencies. Pass-through estimates vary widely; check the latest research rather than a single number.
- Retaliation and targeted pairs (weeks to months): currencies of targeted partners — CNH, MXN, CAD, EUR — often react most to headlines about their own tariffs.
- Confidence in US policy (months to years): unpredictable trade policy can encourage reserve managers and investors to diversify, a slow channel that can weigh on the dollar.
Example
After the 2 April 2025 announcement, the dollar fell rather than rallying, and the DXY dropped roughly 10% over the first half of 2025 — one of its weakest first halves in decades. Gold broke above $3,000 in March 2025 and reached about $3,500 in April 2025 amid that uncertainty. In the 2018–19 trade war, by contrast, the dollar generally strengthened while the Fed moved to three rate cuts in 2019.
Common Mistake
Assuming “tariffs = stronger dollar” because of a textbook model. The April 2025 episode shows the opposite can happen.
Professional Tip
After a tariff headline, check three things in order: US equities, US Treasury yields and the DXY. If all three fall together, you are in a “sell US assets” episode, not a classic risk-off dollar bid.
Which Pairs React Most to Tariff Headlines#
Short Answer
The currencies of the most directly targeted partners — the Chinese yuan (USD/CNH), Mexican peso (USD/MXN) and Canadian dollar (USD/CAD) — usually react most. EUR/USD tends to react less per headline.
Detailed Explanation
- USD/CNH: offshore yuan trades freely around the clock, so it absorbs US–China headlines. In early April 2025 the offshore yuan weakened to a record low beyond 7.4 per dollar during the escalation.
- USD/MXN and USD/CAD: North American exposure to US demand makes both sensitive, although USMCA-compliant goods were exempted from the broad tariffs.
- EUR/USD and GBP/USD: usually smaller reactions per headline, with larger moves driven by Fed–ECB and Fed–BoE policy gaps.
Earlier drafts listed precise 2025–26 ranges for these pairs; they could not be verified and have been removed. Use your own chart history.
Example
On a day when a new Section 301 rate is announced for a specific economy, compare that economy's currency with a control pair (for example USD/CHF). If only the targeted currency moves, the reaction is tariff-specific.
Common Mistake
Trading the same size on every USD pair during a tariff headline. Volatility differs sharply between CNH, MXN and EUR.
Professional Tip
Check option-implied volatility, where available, before scheduled trade-policy dates — it shows how much movement the market expects.
Gold and Tariffs: What the Evidence Supports#
Short Answer
Tariff uncertainty contributed to gold's 2025 rally as one of several drivers, but no gold-specific tariff driver is verified in 2026. Gold's 2026 path — a record near $5,589 in January and a fall to about $4,125 by 29 September — has been driven mainly by rates and oil.
Detailed Explanation
- 2025: gold gained 67.4% (WGC) as central-bank buying, investment demand, Fed cuts in late 2025 and broad policy uncertainty — including trade policy — combined. In August 2025, a customs classification ruling briefly raised the question of tariffs on imported gold bars before the White House said gold would not be tariffed.
- 2026: the tariff burden fell after the Supreme Court ruling. Meanwhile the US–Iran conflict and the Strait of Hormuz standoff pushed Brent near $106–107, August CPI came in at 3.4% y/y, and the Fed hiked to 3.75–4.00% on 16 September. With 10-year yields near 5.2% and real yields near 2.8%, gold fell about 7% in September.
- Central banks: they bought 863.3 t in 2025 (not the “1,100 t” sometimes quoted) and a record 288.9 t in Q2 2026 (WGC). Whether trade policy influences their decisions is not something the data isolates.
Example
If tariffs were still the main gold driver, the February 2026 fall in the tariff burden and the September rate shock would not explain gold's path. The rate shock does: gold fell from about $4,510 to $4,111 in September as yields surged.
Common Mistake
Buying gold on a tariff headline without checking what that headline does to yields and Fed expectations.
Professional Tip
For gold, translate every tariff story into its effect on inflation expectations and the Fed path. Our gold price factors guide explains why real yields dominate.
What 2018–19 Tells Us — and What Is Different#
Short Answer
The 2018–19 trade war was mainly US–China; the dollar generally strengthened and the Fed eventually cut three times in 2019. The 2025 cycle was broader, the dollar fell sharply in the first half of 2025, and in 2026 courts and statutes reshaped the regime.
Detailed Explanation
| Factor | 2018–19 | 2025–26 |
|---|---|---|
| Main target | China | Broad: China, Canada, Mexico, EU and many others |
| Legal basis | Sections 301 and 232 | IEEPA (struck down Feb 2026), then Sections 122, 301 and 232 |
| Fed response | Three cuts in 2019 | Cuts in late 2025, then a hike on 16 Sep 2026 |
| Dollar | Generally stronger | DXY down roughly 10% in H1 2025; about 101.2 in late Sep 2026 |
| Gold | Rose from about $1,200 in 2018 to above $1,500 in 2019 | +67.4% in 2025; record Jan 2026; about −5.6% YTD by 29 Sep 2026 |
Example
In 2019, falling yields after Fed cuts helped gold. In 2026 the Fed is hiking and yields are at 19-year highs — the opposite macro backdrop, whatever tariffs do.
Common Mistake
Copying the 2018–19 playbook without checking whether the Fed is easing or tightening.
Professional Tip
Always pair a historical analogy with the current Fed direction; it usually matters more than the tariff headline itself.
How to Trade Tariff Headlines (Without Getting Wiped Out)#
- Cut leverage on policy days. Court deadlines, USTR announcements and statutory expiry dates (such as 24 July 2026) create gap risk.
- Expect two-way moves. Threats often move markets more than implementation; initial reactions can reverse within hours.
- Separate legal tracks. IEEPA, Section 122, Section 232 and Section 301 tariffs carry different legal and time risks.
- Check the rate channel. For gold and USD pairs, what the headline does to Fed pricing usually matters most.
- Size by volatility. USD/CNH, USD/MXN and XAU/USD can move far more than EUR/USD on the same headline. At about $4,125, one XAU/USD standard lot moves $100 per $1.
Tip: Add the USTR press releases and CBP trade notices to your news watchlist alongside the economic calendar. Most tariff news arrives outside scheduled data slots.
Tariff-Headline Checklist#
- Identify the legal basis of the tariff (IEEPA, 122, 232 or 301) and its duration
- Check which currencies are directly targeted
- Check the effect on US yields and Fed pricing (next FOMC: 27–28 October 2026)
- Reduce leverage and widen stops or stand aside around the announcement
- For gold, check oil and real yields before assuming a safe-haven bid
- Verify the live quote and spread before entering
Key Takeaways#
- The Supreme Court struck down the IEEPA tariffs on 20 February 2026; Section 122 and then Section 301 tariffs followed.
- The realised effective tariff rate was 6.7% in July 2026 (Penn Wharton), not 17–19%.
- Tariffs do not reliably strengthen the dollar — it fell after the April 2025 announcements.
- No gold-specific tariff driver is verified in 2026; oil, the Fed and yields dominate gold.
- Trade tariff headlines with lower leverage and a clear view of the rate channel.
Glossary#
- IEEPA: International Emergency Economic Powers Act; the Supreme Court ruled in 2026 that it does not authorise tariffs.
- Section 122: a Trade Act of 1974 authority allowing temporary tariffs of up to 150 days for balance-of-payments reasons.
- Section 232: national-security tariffs under the Trade Expansion Act of 1962 (used for steel, aluminium and copper).
- Section 301: tariffs responding to unfair trade practices under the Trade Act of 1974, administered by USTR.
- Effective tariff rate: customs duties collected divided by the value of imports.
- USD/CNH: the US dollar against the offshore Chinese yuan.

Living in the GCC and watching USD-pegged currencies absorb dollar volatility is interesting. SAR doesn't move but inflation does — tariffs on imported goods show up in CPI 4-6 months later. Indirect effect that the article hints at.
