Multi-currency financial planning for international investors

If you hold investments in more than one currency — from working abroad, investing internationally, or maintaining accounts in multiple countries — your FI plan needs to handle currency properly.

The multi-currency challenge

Most FI calculators assume everything is in one currency. If you hold £200,000 in UK funds, $80,000 in US equities and €40,000 in European bonds, you need to consolidate these into a single view to answer the question: "Where am I relative to my FI target?"

Manual conversion is tedious and out of date the moment you calculate it. Exchange rates change daily, and your portfolio values change with them — even if the underlying investments haven't moved.

Native currency recording

The best approach is to record each asset in the currency it's held in. A US stock stays in USD; a European fund stays in EUR. The system then converts to your chosen base currency using current market exchange rates.

This has two advantages:

• Accuracy. You see the actual native value alongside the converted value. If GBPUSD moves from 1.25 to 1.30, your US holdings change in GBP terms even though their USD value is unchanged.
• Auditability. You can verify each holding's value in its native currency against your broker statement.

Exchange rates and forecasting

Yield Clarity uses current market exchange rates for consolidation and portfolio valuation. For forecasting, the current rate is applied — the model does not attempt to predict future exchange rate movements.

This is a deliberate simplification. Currency forecasting is notoriously unreliable, and adding currency predictions to a retirement forecast would introduce another layer of false precision. The trade-off is transparency: you know the model assumes today's exchange rates.

Currency risk in FI planning

If your FI target is in GBP but 40% of your portfolio is in USD, a significant USD depreciation would reduce your FI-eligible wealth in GBP terms. This is currency risk.

There's no single correct approach to managing this:

• Some investors accept the risk, viewing multi-currency exposure as diversification.
• Others gradually consolidate into their retirement currency as they approach FI.
• Some use hedged fund versions for non-base-currency positions.

Yield Clarity doesn't prescribe a strategy. It shows you the current consolidated position and lets you run scenarios with different assumptions.
