Set out the instruments of geopolitics and how they affect economies and investments
The idea
States pursue geopolitical aims with three broad kinds of tool. National security tools include armed conflict, espionage and alliances. Economic tools may be cooperative, such as free trade areas, common markets and economic unions, or non-cooperative, such as nationalisation, domestic content requirements and limits on foreign voting rights. Financial tools include the use of a reserve currency and the screening or blocking of foreign investment. Sanctions are targeted restrictions on particular countries, entities or individuals and can cut them off from payment systems and markets. For investors the effects run through prices and risk: sanctions on a commodity exporter tighten supply and raise prices, content rules raise costs and localise supply chains, and heightened tension widens risk premia and redirects capital flows.
A practice question
Which is an example of an economic tool of geopolitics that is cooperative in nature?
- Nationalising foreign-owned assetsWhy not: Nationalisation is an economic tool, but a non-cooperative one that transfers foreign assets to the state.
- Deploying armed forces abroadWhy not: Armed conflict is a national security tool, not an economic one.
- Forming a free trade area — correct
Economic tools include cooperative measures such as free trade areas, common markets and economic unions, and non-cooperative ones such as nationalisation, domestic content rules and limits on foreign voting rights.
A harder one
Restrictions on foreign investment in industries deemed strategic, such as defence technology, are best classified as:
- a national security tool of geopoliticsWhy not: National security tools involve military force, espionage or alliances rather than controls on capital flows.
- a financial tool of geopolitics — correct
- a cooperative economic toolWhy not: Blocking foreign ownership is non-cooperative; cooperative economic tools open markets to partners.
Financial tools include the use of a country's currency and the regulation of foreign investment. Screening or blocking foreign acquisitions in sensitive sectors protects strategic interests but limits capital inflows.
The hardest tier
Broad trade sanctions are imposed on a major commodity exporter. The most likely effect on investment markets is:
- higher commodity prices and supply chain disruption — correct
- lower commodity prices as supply becomes cheaperWhy not: Sanctions remove supply from the global market; less supply for unchanged demand pushes prices up, not down.
- no effect, because sanctions are purely politicalWhy not: Sanctions work precisely by altering flows of goods and capital, so their economic effects are the point of the tool.
Removing an exporter's output from world markets tightens supply and raises commodity prices and volatility. Firms reliant on those inputs face higher costs and disruption, and investors demand higher risk premia in affected sectors.
