Managing Foreign Exchange Risk in UK Estates with Overseas Assets
Key Points
- FX risk is real in probate
UK Inheritance Tax is fixed in sterling at the date of death, but overseas assets remain exposed to currency movements during the probate period, creating the potential for unexpected losses. - Exchange rate movements can erode estate value
Adverse FX moves between the date of death and asset sale or repatriation can materially reduce the funds ultimately realised by the estate, even where asset values remain unchanged. - Early FX planning protects beneficiaries and fulfils duties
Identifying and managing FX exposure early helps probate providers avoid forced asset sales, protect estate value, and demonstrate prudent fiduciary oversight.
UK Inheritance Tax and Foreign Assets
Where an individual is UK-domiciled at death, UK Inheritance Tax (IHT) applies to their worldwide estate. This includes foreign assets such as US shares, overseas bank accounts, or property located abroad, for example in Portugal or Spain.
For IHT purposes, foreign assets are valued at their open market value at the date of death and converted into sterling using HMRC’s official exchange rate on that date. That sterling valuation fixes the IHT exposure, even though the underlying asset remains in a foreign currency.
Why Foreign Exchange Exposure Arises
Although the IHT liability is fixed in sterling, estate administration rarely completes immediately. Probate, asset sales, and the repatriation of funds often take many months.
During this period, foreign assets continue to fluctuate in value against sterling. If exchange rates move between the date of death and the eventual sale or transfer of the asset, the sterling amount realised by the estate may differ materially from the value on which IHT was calculated.
This creates genuine and often significant foreign exchange exposure.
A Simple Example
Assume an estate includes US shares worth $1,000,000 at the date of death, when the GBPUSD exchange rate is 1.25. For IHT purposes, the shares are valued at £800,000. At an IHT rate of 40%, the tax attributable to those shares would be £320,000.
If probate completes several months later and the US dollar has weakened to 1.40, but the shares are still worth $1,000,000, the sterling proceeds on sale would be approximately £714,000. The IHT liability remains based on the original £800,000 valuation, meaning the estate has effectively suffered a currency-driven shortfall.
Reliefs and Their Limitations
Quoted shares may qualify for loss on sale relief if sold within 12 months of death at a lower value for IHT purposes. However, this relief compares sterling sale proceeds with the sterling probate value, meaning currency movements are included in the calculation.
Foreign property does not benefit from the same loss relief regime. As a result, foreign exchange risk on overseas real estate is typically unmanaged unless it is actively addressed as part of the administration process.
Additional Complexity: Foreign Taxes
Further complexity can arise where foreign estate or inheritance taxes apply, such as potential US estate tax exposure on US-situs assets. While double tax relief may be available in the UK, foreign tax credits are calculated in sterling at the exchange rate prevailing when the foreign tax is paid.
Movements in exchange rates between the date of death and the payment of foreign tax can therefore create additional mismatches and further erode estate value.
Why Early FX Advice Matters for Probate Providers
For probate providers administering estates with foreign assets, early identification of foreign exchange exposure is critical.
IHT becomes payable six months after the end of the month of death, with interest accruing on late payment. If overseas assets must be sold or repatriated to meet that liability, adverse currency movements can materially reduce the funds available to the estate.
By engaging a specialist FX adviser at the outset, probate providers can:
- Identify and quantify FX exposure early
- Consider whether hedging solutions, such as forward contracts, are appropriate
- Avoid forced asset sales during periods of currency weakness
- Protect beneficiaries from unnecessary erosion of estate value
- Demonstrate prudent risk management and fulfil fiduciary duties
