In early April 2025, the global economy experienced a sudden jolt. A wave of unexpected US tariff hikes and mounting financial tensions revealed a profound shift in American economic policy—one with far-reaching global implications. At TAC ECONOMICS, we’ve unpacked this pivotal moment in our latest Global Outlook, providing insight into what’s driving this transformation and what to expect moving forward.
1. A Clear Break from Multilateralism
The US has decisively pivoted away from traditional trade norms, opting for a binary strategy:
2. Strategic Ambiguity Rules
There is no clear endgame:
3. Real Economic Costs Already Visible
4. Bond Markets and Political Reactions Intertwined
The sharp correction in US Treasuries forced a 90-day tariff pause—highlighting a volatile new normal where political decisions are reactive to market shocks, not grounded in strategy.
US-China Rivalry Intensifies
The one stable theme: geostrategic confrontation with China. Yet this policy is constrained:
Inflation: A New Spike Ahead
Our modeling shows a 1.5 percentage point increase in US CPI due to the tariffs, with likely spillovers into services and wages. This could push inflation to 4.5% in H2 2025—reviving stagflation fears just as growth slows.
Global Growth: A Year of Desynchronization
The global financial architecture is under stress:
The tariff pause reassured markets temporarily—but without coherent macroeconomic coordination, policy credibility is eroding fast. The Fed’s independence and effectiveness are in question.
We may be witnessing a paradigm shift. The critical question is no longer just about tariffs or inflation—it’s about systemic trust in US leadership and institutions. Can the US reassert itself as a stable anchor for global markets, or are we entering a new era of economic fragmentation and institutional erosion?
The answers will begin to surface in the coming weeks.
