Risk and Performance Analysis · Collective Funds

A bond or international collective fund can lose value through several channels at once. Separating rate, credit and currency risk makes the portfolio easier to evaluate.

Interest rate sensitivity

For conventional fixed rate bonds, prices generally move inversely to yields. Duration provides an approximate sensitivity measure for small yield changes. A portfolio with duration of five years might lose roughly 5% if relevant yields rise by one percentage point, before income and other effects.

This approximation is not a guarantee. Yield curve changes, options and convexity can alter the result. A short holding horizon can make a price decline particularly relevant even when the bonds continue paying interest.

Credit and currency add separate risks

A borrower’s deteriorating outlook can widen credit spreads and reduce bond prices even if government yields are unchanged. Defaults and recoveries introduce further uncertainty. High income can compensate for risk, but it does not eliminate it.

For an unhedged international holding, the investor’s result includes currency translation. If the asset rises 5% in its local currency while that currency falls 10% against the account currency, the combined return is approximately negative 5.5%: 1.05 times 0.90, minus one.

Review hedging and exposure

Ask whether currency is hedged, how much is hedged and what costs or counterparty risks remain. A hedge can reduce one source of uncertainty while leaving the investment’s other risks intact.

Use the fund’s actual duration, credit distribution and currency policy. A label such as income or international is too broad to support a useful stress test.

Try it yourself

An asset returns 8% locally and its currency gains 2% against the investor’s currency. What is the combined return before costs?

1.08 times 1.02, minus one, equals 10.16%.
