It’s about optimising your portfolio - August 2021
By allocating money internationally, you reduce the level of risk associated with achieving a specific rate of expected return, as demonstrated in the riskreturn frontier in Figure 1.
For retirement savers, the classic recommendation is to have a minimum international allocation of 20% to 30% through the cycle. These long-term investors require an annualised return of inflation plus 4% to 5% in rand terms with which they need to buy a basket of local goods and services. Figure 1 shows that at 0% international exposure, these investors get compensated with 1.01 units of return. But by having international exposure of 30%, their units of return increase to 1.27 (and at less risk than a portfolio without any international exposure).
Should you consider investing more than 30% offshore?
Investors who can justify a larger international allocation (more than 30%) include those who:
- spend regularly in foreign currency;
- need to consider offshore bequests because multiple generations live on different continents; and/or
- do not need to draw a domestic income from their savings.
