Why Exchange Rates Matter More Than Ever in 2025

In 2025, currency fluctuations are playing a larger role in UK property investment decisions than at any time in the last decade. A weakening pound can instantly create value for buyers holding stronger foreign currencies, while sudden shifts in exchange rates can change affordability overnight.

For overseas investors, this creates a window of opportunity — particularly in prime and ultra-prime locations where property values are already showing signs of resilience. In some cases, a favourable currency swing can amount to a double-digit discount on a purchase compared with just a few months earlier.

How Currency Movements Impact Buying Power

Consider a buyer with US dollars looking to purchase a £5 million property in London. If the GBP/USD rate shifts from 1.35 to 1.25, the same property effectively costs around $500,000 less in dollar terms. For high-value transactions, these changes are significant enough to alter the timing of a purchase or even expand the buyer’s budget into a higher property bracket.

These movements can be amplified for buyers purchasing through offshore entities or trusts, where income and assets may be spread across multiple currencies (Using Offshore Companies for UK Property Purchases in 2025 and Lending to Offshore Trusts).

Timing Purchases Around FX Trends

Some overseas buyers choose to delay transactions in anticipation of favourable currency shifts. Others move quickly when a sudden swing improves their buying power. In both scenarios, having finance pre-approved is critical.

Trophy properties and prime London apartments often attract multiple offers, and the ability to proceed immediately can be the deciding factor in securing the deal (Private Client Finance for Trophy Properties in 2025).

Private banks are particularly adept at working with international clients in this space, as they can offer multi-currency mortgages that allow repayments to be made in the currency in which the borrower earns. This can reduce exposure to exchange rate volatility and improve long-term affordability (Currency Risk and Income Verification: Challenges of Foreign Income).

Structuring Finance for Currency Advantage

An effective currency strategy goes beyond timing the exchange. For some buyers, it may involve securing a sterling-denominated mortgage while holding assets in a foreign currency. Others might choose a multi-currency facility, enabling them to switch repayment currency if exchange rates move against them.

In certain cases, a cross-collateral arrangement using assets in different countries can also be used to secure a competitive facility without liquidating foreign currency holdings (Cross-Collateral Property Finance in 2025).

Working with a broker who understands both the finance and FX landscape ensures the structure complements the buyer’s broader wealth strategy, rather than simply focusing on the property purchase in isolation.

Opportunities in Prime and Ultra-Prime Markets

Currency-driven opportunities are particularly relevant in London’s prime residential market, which remains one of the most desirable destinations for global capital. Buyers from the Middle East, Asia, and North America often watch exchange rates closely, entering the market when their currency is strongest against the pound.

These trends are also influencing multi-jurisdiction purchases, where an overseas buyer might simultaneously acquire a UK property and refinance an asset abroad to take advantage of both currency and interest rate conditions (Navigating Multi-Jurisdiction Property Purchases in 2025).

Case Study: US Buyer Secures London Property at FX Advantage

Willow Private Finance recently assisted a US client purchasing a £7.5 million Chelsea townhouse. When the GBP/USD rate dropped to its lowest point in over 18 months, the client was able to lock in a saving of almost $700,000 compared to their original budget projections.

We arranged a private bank facility that allowed interest-only repayments in US dollars, with the flexibility to switch to sterling should exchange rates move in the client’s favour in the future. This structure provided cost certainty while retaining the ability to capitalise on currency shifts.

Why Acting Quickly Is Key

Favourable exchange rates can be fleeting. The FX market is influenced by political developments, central bank policy changes, and macroeconomic data — all of which can shift sentiment in a matter of days. Buyers who monitor the market but are not prepared to transact risk missing the opportunity entirely.

By securing finance in advance, overseas buyers can move decisively when the currency market moves in their favour, often ahead of competing bids.
