Editorial
This article outlines the main channels through which geopolitical risk can affect markets and why diversification and planning are used instead of forecasting, with hypothetical numbers.
Contents
Tension between countries or regions, conflict, sanctions, and shifts in diplomatic relations are together called geopolitical risk. When such events dominate the news, many people wonder how their own assets might be affected. This article avoids any particular country or position and sets out a general framework for how geopolitical risk can relate to investing. All numbers in the examples are hypothetical.
What geopolitical risk means
Geopolitical risk is the possibility that political, diplomatic, or military events affect the economy and markets. The kinds of events vary widely, and so does the way they reach markets, which differs from event to event and from period to period.
An important point is that “risk” here does not simply mean something bad will happen. It means the possibility that results deviate from what was assumed. Neither the direction nor the size of that deviation can be known in advance.
Main channels to markets
Even for those who are not directly involved, effects can travel through economic links in several ways.
| Channel | Example |
|---|---|
| Commodity and raw material prices | Prices move on expectations that supplies of energy, food, or materials may be disrupted |
| Supply chains | Transport or production of parts and products is delayed, affecting company costs and results |
| Trade and regulation | Tariffs, export or import limits, and financial sanctions affect corporate business |
| Currencies and interest rates | Capital flows move currency values and rates |
| Investor sentiment | Uncertainty about the outlook leads some investors to reduce risky holdings |
These are only examples, and several channels can operate at once. The same event also affects industries differently. A business that uses a lot of energy may face higher costs, for instance, while a business on the supply side of a resource may see the opposite effect.
A related point is that markets often move on expectations before an event is resolved. By the time a development is widely reported, part of its possible effect may already be reflected in prices, and later moves can then run in a direction that seems unrelated to the headline. This is one reason the connection between news and prices is looser than it appears.
Price moves are hard to predict
When markets become unsettled, it is sometimes said that investors move toward bonds, gold, or certain currencies to avoid risk. That pattern does not always hold, though, and it depends on the nature of the event and on the interest rate and exchange rate conditions at the time. If you decide in advance that “this is what will happen”, it becomes hard to respond when prices move the opposite way.
The size and duration of the effect also differ by event. In some cases the effect fades in a short time, and in others it lingers, and this is often clear only in hindsight. For that reason, trying to form a view on events and time trades around it is considered difficult to repeat.
Preparing instead of predicting
If prediction is hard, it is more realistic to think about a structure that does not break down badly when forecasts are wrong. Diversification is the standard idea here.
- Across assets: Spread money over assets with different price behavior, such as stocks, bonds, cash, and gold.
- Across regions: Avoid depending on one country or region alone.
- Across time: Invest in installments over a period rather than all at once.
- Cash on hand: Keep living expenses and an emergency fund separate from investments.
None of these measures is free. Holding more cash or bonds usually means giving up some of the growth potential that stocks offer over long periods, and spreading across regions adds currency exposure. The aim is not to eliminate risk but to choose which risks you are willing to carry, and in what proportion, so that no single event decides the outcome.
A hypothetical example shows the effect of diversifying. Suppose 1,000,000 yen is split into 500,000 yen of stocks, 300,000 yen of bonds, and 200,000 yen of cash. If stocks fall 20% and the others stay unchanged, the stocks become 500,000 x 0.8 = 400,000 yen, and the total is 400,000 + 300,000 + 200,000 = 900,000 yen, a 10% decline overall. Had the whole 1,000,000 yen been in stocks, it would be 800,000 yen (1,000,000 x 0.8), a 20% decline. In reality bonds and cash can also fluctuate, and diversification does not remove every loss. To compare combinations of assets, you can use the three-asset comparison tool (Japanese).
Living with the news
- Do not judge from headlines alone; separate facts from speculation and opinion.
- Check the source of assertive social media posts and of content meant to stir up anxiety.
- Map out once which parts of your own assets could be affected, and through which channel.
- Avoid hurried decisions and review according to a plan set beforehand.
Looking at how past events were reported can also be instructive, with one caveat: hindsight makes outcomes look more obvious than they were. At the time, people faced incomplete information and several competing explanations. Reading old coverage with that in mind is a reminder that confident forecasts made in the moment often turned out to be wrong in both directions, and that a plan which does not depend on a single forecast is easier to keep.
Points to consider and risks
Geopolitical risk is a risk whose occurrence, and whose market effects if it occurs, cannot be known accurately beforehand. Moving assets heavily on a prediction about a specific event can enlarge losses if the prediction turns out wrong. Even a diversified portfolio can lose value when markets as a whole fall at the same time.
What matters is to decide your purpose, time horizon, and tolerable loss first, and to return to that framework when the news unsettles you. Money for long-term goals and money you plan to use in the near future call for different levels of risk.
