Decoupling between the United States and China is accelerating rapidly, with both nations dismantling economic ties through higher tariffs and an expanding array of non?tariff barriers, according to a new note from Capital Economics.

Key Takeaways

Overdrive Decoupling

“U.S.?China decoupling is going into overdrive,” driven by escalating reciprocal tariffs and fresh barriers that extend beyond simple duties.

Tariff Trajectory

Elevated duties on both sides now suggest that most bilateral trade could cease within a couple of years if current trends persist.

Non?Tariff Measures

Recent moves include tighter U.S. export controls on advanced semiconductors and China’s suspension of Boeing deliveries and postal parcel services.

Skepticism on a “Big Deal”

Despite former President Trump’s stated openness to negotiate, Capital Economics warns not to count on any substantive reset of U.S.–China relations.

Looking Ahead: Investment Flows as the Next Front

“America First Investment Policy”

Released in February, this policy outlines potential restrictions such as delisting Chinese firms from U.S. exchanges and curbing cross?border capital flows.

Future Battleground

If decoupling continues, investment flows—from venture capital to public equity—are likely the next area of contention.
