Currency & FX Planning — for International Investors & Expats
Currency risk is one of the most underestimated threats to the real value of an expat's wealth. A GBP pension drawn in euros, a USD investment portfolio funding sterling school fees, a property in Thailand financed from a UK account — each introduces an FX exposure that can erode returns as significantly as a poor investment decision. We help internationally mobile clients understand, measure, and manage their currency risk.
Understanding the risk
Why currency risk matters more than most expats realise
GBP/EUR has moved by more than 20% within a single calendar year on multiple occasions since 2015. For an expat drawing a GBP pension and living in the eurozone, that swing represents a 20% real-terms change in purchasing power — entirely independent of any investment return. No investment manager can reliably recover a 20% income loss caused by currency movement.
The same issue applies in reverse: a USD investment portfolio funding GBP spending faces the opposite exposure. International portfolios denominated in multiple currencies are exposed to multi-currency risk that compounds across different markets and asset classes.
Common currency mismatches for expats
- GBP pension → EUR spending (UK pension, eurozone resident)
- USD salary → GBP savings (Middle East employment, UK assets)
- GBP property income → THB living costs (UK rental, Thailand retirement)
- EUR portfolio → GBP school fees (European investment, UK boarding school)
- Multi-currency investment portfolio → single-currency retirement income requirement
- USD offshore bond → GBP IHT liability on death
Mapping your exposure
Understanding your currency exposure
Base currency
Your base currency is the currency in which you primarily spend and measure your wealth. For most UK-connected expats, GBP remains the base currency even after departure — particularly where there are UK-based family, property, school fees, or eventual repatriation plans. For long-term Gulf residents, USD (or the pegged AED) is often a more practical base. Identifying your base currency is the first step in any FX strategy.
Investment currency vs spending currency
The currency your investments are denominated in is your investment currency. The currency you spend is your spending currency. If these differ, you have FX risk. A global equity fund denominated in USD generates USD-based returns — if you spend in GBP, every withdrawal involves a USD/GBP conversion. Over time, the difference between these currencies materially affects your real return.
Income currency vs spending currency
This mismatch is particularly common for expats. A GBP pension received monthly but spent in EUR means converting GBP to EUR 12 times a year — each time at whatever the prevailing rate happens to be. Over a 20-year retirement, the cumulative impact of exchange rate movements and conversion costs can be substantial.
Estate currency vs liability currency
If your estate holds USD assets but your IHT liability is calculated and payable in GBP, there is a currency mismatch in your estate that a life assurance policy — denominated in GBP — can resolve. Similarly, if school fee obligations are in GBP but savings are in AED, the AED/GBP rate at the time fees are due determines the effective cost.
Managing the risk
FX strategies for internationally mobile investors
Accept natural volatility
The simplest approach — hold investments in multiple currencies and accept that your base-currency returns will vary with exchange rates. Appropriate if you have income in multiple currencies that broadly offset one another, or if your investment horizon is long enough that short-term FX moves are immaterial.
Match investment to spending currency
Ensure the currency in which you hold and distribute investments matches the currency in which you actually spend. If you live in the eurozone, hold EUR-denominated assets or EUR share classes of global funds. Eliminate the FX conversion step in your income drawdown.
Currency-hedged fund share classes
Many global equity and fixed income funds offer hedged share classes — for example, a global equity fund with a GBP-hedged share class that neutralises USD/EUR/JPY exposure relative to GBP. The hedge comes at a small cost (the interest rate differential between currencies). Useful for de-risking a large allocation to a non-base currency.
Forward contracts
Lock in a specific FX rate for a transaction on a future date — typically 3 to 12 months forward. Eliminates rate uncertainty for a known future payment. Requires a specialist FX provider or bank with a forward contract facility. A small deposit (margin) is typically required at inception.
Regular exchange programme
Convert a fixed amount at regular intervals regardless of the rate — the international equivalent of pound-cost averaging. Smooths out the entry price over time, avoiding the risk of converting a large sum at a temporarily unfavourable rate. Works well for pension income that arrives in GBP and needs to be spent in EUR or AED.
Practical banking
Multi-currency banking for expats
Why multi-currency accounts matter
A standard UK current account automatically converts foreign currency receipts into GBP at the bank's spot rate — often 1–3% worse than the interbank rate. Over time, for clients with regular cross-currency flows, this is a significant hidden cost.
Multi-currency accounts allow you to receive, hold, and spend in multiple currencies without forced conversion — converting only when the rate is favourable or when you actually need to spend in a particular currency.
Options available
- Wise (formerly TransferWise) — multi-currency account with near-interbank rates and local bank details in USD, EUR, GBP, AED, and others. Low cost, easy access.
- Revolut — multi-currency current account with physical card. Fee-free conversion up to monthly limit at interbank rate. Good for day-to-day spending.
- HSBC Expat — full banking relationship with multi-currency accounts and investment platform. Based in Jersey, suitable for larger balances and international transfers.
- Lloyds International — Isle of Man based. Multi-currency savings and current accounts for expats. Strong for GBP, EUR, and USD.
- Specialist FX providers (e.g. Moneycorp, OFX, Clear Treasury) — for large transfers. Typically 0.1–0.5% spread vs 1–3% at high street banks.
Gulf clients
Dollar-pegged currencies in the Gulf region
For clients based in the Gulf Cooperation Council (GCC) countries, the FX landscape is simplified by the fact that most regional currencies are pegged to the US dollar. This eliminates intra-GCC currency risk and simplifies USD-denominated investment planning.
| Currency | Peg rate | Planning note |
|---|---|---|
| UAE Dirham (AED) | USD (3.6725 since 1997) | Fully fixed peg, maintained consistently for 28+ years. No currency risk for USD-earning clients resident in UAE. |
| Saudi Riyal (SAR) | USD (3.75) | Fixed peg since 1986. Largest GCC economy. SAR/GBP and SAR/EUR risk remains for UK or European-connected clients. |
| Qatar Riyal (QAR) | USD (3.64) | Fixed peg. Qatar has one of the highest GDPs per capita globally. Stable for USD-based planning. |
| Bahrain Dinar (BHD) | USD (0.376) | Fixed peg since 2001. Strong USD relationship simplifies dollar-denominated investment planning. |
| Kuwait Dinar (KWD) | Basket (USD-dominant) | Pegged to a basket of currencies since 2007 (de-pegged from USD alone). Very low volatility; historically the world's highest-valued currency unit. |
Although the AED/USD peg has been in place since 1997 and is considered highly stable, currency pegs can change. For very large or very long-term positions, some diversification outside the peg remains prudent. The primary currency risk for Gulf-based UK nationals remains the USD/GBP rate — which can be volatile.
Wrappers & currency
Offshore bonds and base-currency matching
Offshore investment bonds from Isle of Man, Dublin, and Channel Islands providers are available in USD, GBP, and EUR denominations. You can hold the same underlying fund portfolio inside a GBP-denominated bond or a USD-denominated bond — but the reporting currency, the withdrawal amount, and the death benefit are denominated accordingly.
Matching your bond's denomination to your base currency eliminates the currency mismatch between your investment wrapper and your spending. For a UAE-based client spending in AED (pegged to USD), a USD-denominated bond is a natural fit. For a eurozone-resident UK national, a EUR-denominated bond may be more appropriate than a GBP one.
Currency choices within a portfolio
- Global equities provide natural geographic currency diversification — a global tracker holds assets in USD, EUR, JPY, GBP, CHF, and more
- Currency-hedged vs unhedged: hedged fund share classes reduce FX volatility at a cost; unhedged provides greater diversification
- Fixed income is more currency-sensitive than equities — a GBP bond fund and a USD bond fund serve very different purposes in a portfolio
- Gold is USD-denominated globally — GBP-based investors in gold have USD/GBP exposure to manage
Returning to the UK
Repatriation and TRF planning
Bringing offshore funds back to the UK — repatriation — has historically been a taxable event for non-doms under the remittance basis. Following the April 2025 abolition of the remittance basis, this changes significantly.
The Temporary Repatriation Facility (TRF), available across the three tax years from 6 April 2025 to 5 April 2028, allows individuals who accumulated unremitted foreign income and gains while on the remittance basis to bring those funds to the UK at a flat 12% rate (in 2025–26 and 2026–27), rising to 15% (in 2027–28), rather than at full income tax or CGT rates. This is a significant one-off opportunity for clients with large pools of historically unremitted overseas income.
- Available 6 April 2025 – 5 April 2028 only
- 12% flat rate in 2025–26 and 2026–27; 15% in 2027–28
- Applies to pre-6 April 2025 unremitted foreign income and gains
- Available to those who used the remittance basis at any point
- Does not apply to post-April 2025 income and gains
- Election made on self-assessment return; claims must be quantified
The TRF window is narrow. Clients with unremitted overseas income or gains should seek advice promptly to model whether using the TRF is beneficial for their specific position.
