A US Supreme Court decision striking down President Trump's emergency tariffs has unintentionally benefited China. By lowering the effective tariff rate by 7%, it reduces external pressure on Beijing to reform its export-driven economic model and weakens Trump's negotiating position ahead of a key summit with Xi Jinping.

The success of tariffs hinges on the insight that China's economic model prioritizes volume and employment over per-unit profitability. This creates a vulnerability where Chinese producers are forced to absorb tariff costs to maintain output, effectively subsidizing the tariff revenue and preventing significant price increases for US consumers.

While the base case is that the President would replace tariffs struck down by the Supreme Court, there's a growing possibility he won't. The administration could use the ruling as a politically convenient way to reduce tariffs and address voter concerns about affordability without appearing to back down on trade policy.

Despite fears from announced tariffs, the actual implemented tariff rate on U.S. imports is only 10.1%, not the computed 17-18%. This is due to exemptions, trade deals, and behavioral changes by companies. This gap between rhetoric and reality explains the unexpectedly strong 2025 performance of emerging markets.

Despite US tariffs, China’s trade surplus reached a record high. This is because China diversified exports to emerging markets, utilized transshipment through other countries, and key allies have not joined the US in a broad trade war.

The legal underpinnings of US tariffs are changing, moving from temporary IEPA authorities to more durable Section 301 and 232 investigations. Despite this complex legal transition, economists expect the aggregate effective tariff rate to remain roughly the same, stabilizing around 10% from a macro perspective.

The temporary 15% tariffs under Section 122 expire near the midterm elections. Given the political unpopularity of high tariffs, it is unlikely the administration will raise them further in the medium term, effectively capping rates at this level to appeal to voters concerned about affordability.

Contrary to the populist framing of his trade policy, recent analysis reveals that American consumers bear almost the entire financial burden (94%) of tariffs. This policy acts as an unnecessary 2% tax on the economy, reducing prosperity without fostering significant growth or innovation.

The primary goal of certain US tariffs is not to generate revenue but to strategically weaken China's economy. By incentivizing US businesses to leave China, the US aims to slow its rival's growth, thereby protecting the dollar's global reserve status from the rising yuan.
