The effective US tariff rate has risen from 2.1% to 11.7% under Trump. Here’s how the tariff regime is reshaping global supply chains, consumer prices, and the trade war outlook for 2026.

In 2025, the Trump administration implemented the most sweeping overhaul of US trade policy since the Smoot-Hawley Tariff Act of 1930. Through executive action — primarily invoking emergency economic powers and national security statutes — the administration raised the effective US tariff rate from 2.1% to an estimated 11.7% as of January 2026.

Eighteen months later, the consequences of that decision are visible across every dimension of the US and global economy: in consumer prices, in supply chain restructuring, in the Federal Reserve’s inflation calculations, and in the diplomatic relationships that underpin global trade.

The tariff regime is not an abstract policy debate. It is a tax — and like all taxes, it has winners, losers, and unintended consequences that took time to manifest and will take years more to fully resolve.

The Scale of the Tariff Shock

To appreciate the magnitude of the 2025 tariff escalation, the baseline comparison matters. Before the first Trump administration’s tariff actions in 2018, the average US effective tariff rate on imports was approximately 1.5%. The first Trump term raised it to approximately 3%. The second term’s actions pushed it to 11.7% — a level not seen in the US in decades.

The mechanics varied by category:

• China-specific tariffs remained elevated and in many cases were increased further, targeting electronics, machinery, textiles, and consumer goods
• A 10% global baseline tariff on all imports was implemented through executive action, though this was challenged in the courts
• Sector-specific tariffs targeted steel, aluminium, solar panels, electric vehicles, and semiconductors from multiple origin countries

The Supreme Court rejected several of the most aggressive tariff actions in 2025, ruling that some executive tariff applications exceeded statutory authority. This opened the door for importers to seek refunds on improperly collected duties — a complex refund process that the administration has contested aggressively. The Supreme Court’s intervention did not eliminate the tariff regime; it trimmed its most legally exposed elements while leaving the core architecture intact.

A 10% global baseline tariff remains in effect as of June 2026.

Who Is Actually Paying the Tariffs

The most persistent economic misconception about tariffs is that foreign exporters pay them. They do not. Tariffs are paid by importing firms — US companies that purchase foreign goods — and the economic burden is distributed between exporters, importers, and consumers depending on market conditions.

The best available evidence suggests that more than 50% of Trump tariff costs are now being passed through to US consumers — a pass-through rate that has been somewhat slower than the near-100% observed under the first-term tariffs, but is accelerating as inventory buffers built before tariff implementation are depleted.

For the median US household, the effective tariff tax represents a meaningful annual cost increase — concentrated in electronics, clothing, furniture, appliances, and consumer goods where import shares are high and domestic substitutes are limited or more expensive.

The pass-through to prices has been one of the primary contributors to US inflation remaining above 3% — and is a key reason why the Federal Reserve’s task of returning inflation to 2% is more difficult than a simple demand-management problem would suggest.

Supply Chain Restructuring: Three Years In

The tariff regime has succeeded in its stated objective of prompting supply chain diversification away from China. But “diversification” has not meant “reshoring.” The dominant pattern has been near-shoring — shifting production to third countries that are not subject to the highest US tariff rates.

Vietnam, Mexico, India, Bangladesh, and Indonesia have been the primary beneficiaries of China-targeted tariff diversion. US imports from these countries have increased substantially since 2022, with Vietnam in particular becoming a major hub for electronics assembly, textile production, and component manufacturing previously concentrated in China.

The irony is that much of this production still relies on Chinese inputs — materials, components, and intermediate goods that flow through third-country manufacturing before reaching the US market. The tariff regime has in many cases added a processing step to the supply chain without fundamentally reducing Chinese industrial participation in global production networks.

Mexico, benefiting from the US-Mexico-Canada Agreement, has seen a surge of near-shoring investment from both US and Chinese firms seeking US market access through a tariff-advantaged production base. This has created genuine economic activity in Mexico while raising questions about whether the tariff regime is achieving its intended effect on Chinese production capacity.

China’s Response: Export Diversification and the Trade Surplus

China’s trade surplus — the gap between what it exports and what it imports — has actually expanded in 2026, despite (or perhaps because of) the US tariff regime. Chinese exporters have aggressively diversified their market base, deepening trade relationships with:

• Southeast Asia (ASEAN markets, particularly Vietnam, Indonesia, Thailand)
• Latin America (Brazil, Mexico, Argentina)
• Africa (through the Belt and Road infrastructure network)
• Middle East (Gulf states diversifying from Western supply chains)
• Russia (bilateral trade dramatically expanded since Western sanctions)

This market diversification has reduced China’s vulnerability to US tariff pressure while maintaining the export-led growth model. The result is a structural change in global trade flows — with Chinese goods increasingly reaching the world through routes that bypass direct US market entry.

The EU has responded separately. European tariffs on Chinese electric vehicles, implemented in 2025, represent the most significant trade action in the China-Europe relationship in years. But China’s response has been measured — targeting European luxury goods with retaliatory measures while continuing to invest in European market access through investment in non-tariffed segments.

The Inflation Arithmetic

The tariff-inflation relationship is one of the most debated and most significant economic linkages in 2026.

The direct mechanism is straightforward: tariffs raise the cost of imported inputs, which businesses pass through to consumer prices. The indirect mechanism is subtler: tariffs reduce import competition, allowing domestic producers to raise prices without competitive constraint. Both channels are operational in the current US economy.

Stanford’s Institute for Economic Policy Research estimated that tariff pass-through to consumers now exceeds 50%, with the full pass-through taking 12–18 months from tariff implementation. Given the tariff escalation of 2025, the full inflationary impact is still working its way through the system as of mid-2026.

This creates a structural floor on US inflation that makes the Federal Reserve’s 2% target difficult to achieve without either reversing the tariff regime (a political impossibility under the current administration) or engineering a significant recession that reduces demand enough to offset the supply-side price pressure.

The Fed cannot solve a tariff-driven inflation problem with interest rate tools alone. This is the core of the policy trap that Kevin Warsh inherited upon taking the Fed chair position.

The WTO and the Multilateral Trade Framework

The US tariff regime has created significant strain on the World Trade Organization framework. Multiple WTO dispute settlement proceedings have been filed by trading partners including the EU, China, Japan, South Korea, and Canada. The US has contested these proceedings and has maintained its practice of blocking WTO Appellate Body appointments — a practice that began in the first Trump term and has effectively disabled the WTO’s binding dispute resolution mechanism.

The practical consequence: the global trading system has fragmented into a series of bilateral and regional arrangements, with the WTO’s rules-based framework increasingly supplemented or supplanted by power-based bilateral negotiations.

For businesses operating across borders, this fragmentation creates compliance complexity, supply chain uncertainty, and strategic risk that has no precedent in the post-war era of multilateral trade liberalisation.

What Comes Next: The Second Half of 2026

Several tariff-related developments are likely to shape the trade environment in the second half of 2026:

Supreme Court refund proceedings — the ongoing dispute over duty refunds for imports collected under executive actions that courts ruled as exceeding statutory authority. Resolution will affect importers’ balance sheets and the effective tariff rate going forward.

EU-US tariff negotiations — the Biden-era tariff truce framework has partially frayed under the Trump administration’s more aggressive posture. EU-US talks on steel, aluminium, and digital services remain ongoing and unresolved.

China-US trade dynamics — with China’s trade surplus expanding and US domestic pressure for further action on Chinese imports growing, additional tariff escalation cannot be ruled out. The November 2026 midterm elections create political incentives for trade action.

WTO dispute outcomes — while the Appellate Body remains disabled, preliminary panel rulings could create diplomatic pressure points with major trading partners.

The Bottom Line

The Trump tariff regime has fundamentally altered the US and global trade landscape. The effective tariff rate of 11.7% represents the most significant barrier the US has erected to international commerce in generations, with consequences that run from consumer prices and Federal Reserve policy to supply chain geography and WTO institutional legitimacy.

The tariff regime is not going away. Political economy — domestic manufacturing interests, national security framing, and electoral incentives — makes tariff rollback extremely unlikely under the current administration.

The relevant questions for investors and businesses are not whether tariffs will be reversed, but how supply chains adapt, how much of the inflationary pass-through remains ahead, and whether the trade war escalates or stabilises in the second half of 2026.

FAQ

Q: What is the current US tariff rate in 2026?
A: The US effective tariff rate rose from approximately 2.1% before the Trump administration to an estimated 11.7% as of January 2026. A 10% global baseline tariff on all imports remains in effect after the Supreme Court struck down some of the most aggressive executive tariff actions.

Q: How do tariffs affect inflation in 2026?
A: More than 50% of tariff costs are now being passed through to US consumers, according to Stanford SIEPR research. This represents a structural supply-side inflation pressure that the Federal Reserve cannot resolve through interest rate policy alone.

Q: What happened to US-China trade in 2026?
A: US-China direct trade has declined under tariff pressure, but China has diversified its export markets significantly — increasing flows to Southeast Asia, Latin America, Africa, and the Middle East. China’s overall trade surplus has actually expanded in 2026.

Q: How are tariffs affecting US consumers in 2026?
A: US consumers are facing higher prices on electronics, clothing, appliances, and consumer goods as tariff costs are passed through the supply chain. This contributes to the inflation reading of 4.2% in May 2026 and reduces household purchasing power.
