How geopolitical risk affects investments

What types of geopolitical risk are there?

Memorize

Investors sort geopolitical risk by whether it can be seen coming.

Geopolitical risk

• Event risk Memorize known in advance, set date (election, referendum)
• Exogenous risk Memorize sudden, unanticipated (disaster, uprising, invasion)
  • Black swan risk rare, hard to predict, large impact
• Thematic risk Memorize known, evolves over time (climate, cyber, migration)

Type	Known in advance?	Example
Event risk	Yes, a set date	A referendum set for June on capping foreign ownership of banks
Exogenous risk	No, sudden	A volcanic eruption that closes a major port; a sudden coup
Thematic risk	Yes, but evolves over time	Climate change, cyber threats, migration, populism

A black swan risk is an exogenous event that is rare and hard to predict but has a large impact.

How big is a risk: likelihood, velocity and impact?

Memorize

An investor asks three questions about each risk.

• Likelihood. The likelihood is the probability it happens. Judging it is more art than science. Cooperative, globalized countries are less likely to be targeted but more exposed through their partners.
• Velocity. The velocity is the pace at which a risk affects the portfolio.
• Size and nature of impact. The effect may be discrete (one company or sector) or broad (a country or the world). It tends to be larger in a downturn.

Velocity	Typical effect	Investor reaction
High (short term)	Market-wide volatility, flight to quality; black swans	Tactical moves; usually no long-term change
Medium	Impairs processes and costs in specific sectors, lowering valuations	Adjust sector exposures
Low (long term)	Environmental, social, governance and growth effects	Adjust strategic asset allocation

Combine all three. A likely but trivial risk needs little work. An unlikely but severe one deserves a scenario plan, not constant monitoring. Some risks have more than one speed: a sharp first reaction followed by slower effects that last longer.

Exam tip Ask “how fast?” first. Fast: markets and tactics. Medium: sectors. Slow: strategic allocation.

How do scenarios and signposts help?

Use it

No single forecast can capture a risk that moves in steps. Scenario analysis evaluates portfolio outcomes across possible states of the world. A simple version starts with a base case (the most impactful outcome and how likely it is), then adds upside and downside cases. It can be qualitative, or quantitative, such as measuring the portfolio’s sensitivity to one factor (interest rates, prices or exchange rates) or replaying an extreme event. Teams that read the same research and speak to the same clients risk groupthink , thinking as a group in a way that discourages creativity, so the process needs deliberately varied views.

A signpost is an indicator, market level, data point or event showing that a risk is becoming more or less likely. Read signposts like a traffic light.

• Green: likelihood, velocity or impact is low. No action.
• Amber: medium. More caution and preparation.
• Red: high. An action plan may be needed.

Good signposts come from the assumptions behind a scenario. Watch policy, not just politics: two leaders may differ a lot in style, but the policies enacted are what move portfolios. Some combinations are strong warnings: high inflation with rising unemployment can signal unrest, and a currency peg with collapsing export revenue can precede a change of exchange rate regime.

How does it show up in portfolios?

• Fast risks swing commodities, currencies, equities and bond yields.
• Slow risks lower revenues, raise costs and cut valuations.
• Persistent risk raises the return investors require, which is a higher discount rate. That is why emerging and frontier assets trade at a discount to developed ones.

Investors act top-down, through country allocation and capital market assumptions, or bottom-up, with the risk as a factor in security analysis. Low risk tolerance may mean hedging or lower exposure. A long horizon can turn a shock into a buying opportunity.

Go deeper News-based geopolitical risk indexes

Know the idea

One index counts news articles about geopolitical tension to give a real-time gauge of perceived risk. Elevated readings tend to coincide with lower investment and lower equity prices, and over time the threat of an event can weigh on markets even more than the events themselves, which is why signposts include talk and positioning, not only outcomes.

Go deeper Diversified production: more disruptions, smaller ones

Know the idea

A company with plants in many countries is more likely to see some disruption somewhere, because it has more places for things to go wrong. But each disruption hits a smaller part of output. Diversification therefore raises the likelihood of a disruption and lowers the impact, which is why the two should be judged together.
