Single-Country Risk
Why every single-country concentration should be a deliberate choice with full awareness of what is excluded, illustrated through Singapore and China examples.
Every single-country bet should be deliberate, with full awareness of what is excluded. Too many investors arrive at concentrated country positions by default rather than by decision.
The Scale of Exclusion
- A Singaporean investing only in Singapore stocks excludes 99%+ of global investable market capitalisation. Home bias feels safe but is extreme concentration risk disguised as familiarity.
- An investor concentrated entirely in China excludes 96%+ of global markets. Even if the valuation case is sound — and it may well be — you are betting that China will outperform the rest of the world by enough to justify the exclusion of everything else.
In both cases, investors may turn out right. But it should be a deliberate choice. An investor who cannot articulate why they exclude the rest of the world has not made a decision — they have arrived at a position by default.
What You Are Actually Betting
A single-country allocation is not just a bet that the country will do well. It is a bet that it will do well enough to compensate for:
- The diversification you gave up
- The sectors and industries that country lacks
- The political, regulatory, and economic risks specific to one jurisdiction
- The opportunity cost of excluding every other market
Each of these needs to be weighed against the expected outperformance. Most investors who hold single-country positions have not done this analysis explicitly.
Using Global Indexes as Calibration
VWRA or similar global ETFs solve single-country risk by giving proportional exposure across 49 markets. But even if you choose not to hold a global index, use it as a calibration tool.
Look at your actual portfolio allocation by country. Then compare it to global market weights. Where you deviate, you should be able to explain why. If Singapore is 1% of global markets but 80% of your portfolio, that is a 79-percentage-point active bet on Singapore. Is that intentional?
The Middle Path
Single-country concentration and pure global indexing are not the only options. An investor who wants deliberate overweight to a specific market can hold a global index as the core and add country-specific exposure as a satellite. This way the overweight is visible, measurable, and reversible — rather than being the entire portfolio by default.
