How diversification is built
Spreading exposure only works if the drivers differ. A second country can still share a currency squeeze, a credit cycle, or a single buyer base.

Global diversification is the idea that claims do not all fail for the same reason at the same time. The idea is sound. The slogan is not. Owning a second apartment, a foreign bank deposit, and a listed fund does not diversify anything until you can say which risk each one actually carries.
The IMF’s balance-of-payments manual sorts cross-border investment into functional categories: direct investment, portfolio investment, financial derivatives, other investment, and reserves. The categories exist so compilers can describe positions. They do not promise that those positions will move differently. A portfolio claim and a directly held building can still depend on the same interest-rate cycle and the same currency.
The cost sits inside the spread
A second legal system is a real form of spread, and it is also a cost. Someone has to understand the title, the tax, and the exit. Singapore, the United Kingdom, and the United Arab Emirates are all internationally used markets. They are not three independent bets. Finance, trade, and the availability of dollar funding can move them together even when local planning law does not.
The useful test is boring. Write the shock you are trying to survive: a fall in one city’s occupier demand, a change in one tax code, a loss of convertibility, a repair you cannot fund. Then ask which holding still functions if that shock arrives. If every holding fails the same test, the map was decoration.
Nothing on this page is an allocation. GRIP does not suggest a mix of countries, funds, or buildings. The research question is whether a proposed spread changes the risks, or only the letterhead.
