Tariffs and transition: Geopolitical uncertainty and financial markets
30 July 2025
When we talk about geopolitics, we often default to the geopolitics of war and physical conflict. However, geopolitics centres on foreign relations and economic security, from which war ensues. The most significant impact on the global economy and financial markets in 2025, so far, has been Trump’s trade tariffs and the fears of a full-blown trade war. The escalation in trade tariffs by the US culminated in the Liberation-Day tariff announcement on 2 April, where even the penguins of Heard Island had to prognosticate on the implications of a 10% reciprocal tariff. Since then, we have had an environment of TOTO – tariffs on, tariffs off – with various pauses and extensions. These are meant to come to an end on 1 August 2025, yet we still cannot be certain.
