When people think about buying property overseas, they usually focus on the obvious things first.
Location.
Price.
Rental yield.
Legal process.
Lifestyle.
But there is another part of the purchase that can make a significant difference to the final cost: currency.
For anyone buying property abroad from the UK, US, Europe or another overseas market, foreign exchange should not be treated as a last-minute admin task. It is part of the financial planning process.
And in uncertain markets, it becomes even more important.
Why global events affect overseas property buyers
The Strait of Hormuz is one of the world’s most important energy routes. It sits between Iran and Oman and acts as a key passage for oil and gas moving out of the Gulf.
According to the U.S. Energy Information Administration, oil flows through the Strait averaged 20.9 million barrels per day in the first half of 2025. That was equal to around 20% of global petroleum liquids consumption. UNCTAD also describes the Strait of Hormuz as one of the world’s most critical maritime chokepoints, carrying around a quarter of global seaborne oil trade, as well as significant volumes of liquefied natural gas and fertilisers.
That is why any serious disruption in this region can quickly affect wider markets.
When tension rises around major energy routes, the impact does not stay local.
Oil prices can move.
Shipping costs can change.
Airlines can face higher fuel pressure.
Inflation can become harder to control.
Interest rate expectations can shift.
Currency markets can become more volatile.
This is why geopolitical events matter to international property buyers. Even if you are buying a villa in Spain, an apartment in Dubai, a holiday home in Greece or an investment property in Bali, global currency movements can still affect your budget.
The property price is only one part of the real cost
A property listed at €300,000, $400,000 or AED 1.5 million may look straightforward on paper.
But if you are converting from pounds sterling into another currency, the final cost can move before you complete.
A small change in the exchange rate can make a noticeable difference.
For example, if you are transferring a large deposit, paying stage payments on an off-plan property, completing on a resale home, or moving funds for taxes and legal fees, exchange rate movement can affect how much you actually pay in your home currency.
This is especially important when buyers are working to a fixed budget.
A property may still be the same price locally, but if your exchange rate worsens, the true cost to you increases.
Why FX should not be left until completion
Many overseas buyers only think about currency when they are ready to send the money.
By then, the rate may have moved.
In calmer markets, that may not feel urgent. But during periods of geopolitical instability, inflation pressure and interest rate uncertainty, currency movements can happen quickly.
Sterling, the euro and the US dollar can all move on economic data, central bank decisions, energy price shocks and political headlines.
That is why buyers should look at their foreign exchange position earlier in the process, not just when completion is due.
What overseas buyers should consider
Currency planning does not mean trying to predict the market perfectly. It means understanding your exposure and looking at the options available before you move large sums of money.
Overseas property buyers may want to consider:
Whether they need to transfer a deposit soon
Whether they have stage payments due on an off-plan property
Whether they are completing in a different currency
Whether their budget is sensitive to exchange rate movement
Whether they want to secure a rate in advance
Whether they need guidance before moving funds internationally
This is particularly relevant for buyers purchasing in euros, US dollars, UAE dirhams or other major international currencies.
Energy shocks, inflation and currency volatility
Energy prices matter because they feed into wider inflation.
When fuel costs rise, transport becomes more expensive. Airlines, shipping companies and logistics firms can all feel the pressure.
Higher energy prices can make inflation harder to bring down. If inflation stays elevated, central banks may keep interest rates higher for longer than markets originally expected.
That matters for currency markets.
Currencies are heavily influenced by interest rate expectations, inflation forecasts and investor sentiment. When the outlook becomes uncertain, exchange rates can move sharply.
For overseas property buyers, this can affect the timing and cost of a purchase.
Why this matters for property investors
For investors, currency movement can affect more than just the purchase price.
It can also affect:
The return on investment
Rental income when converted back into your home currency
Mortgage payments if borrowing abroad
Ongoing costs such as service charges and management fees
Future resale value when funds are repatriated
A strong property investment can still be impacted if the currency side is not considered properly.
This is why serious investors should look at both the property fundamentals and the financial mechanics of moving money internationally.
The mistake many buyers make
One of the most common mistakes international buyers make is assuming the exchange rate they see today will be the same when they complete.
It often will not be.
This is particularly true with off-plan property, where payments may be spread over months or years.
A buyer may reserve a property based on one exchange rate, then find later payments cost more because the market has moved.
That does not mean buyers should panic. It simply means FX planning should sit alongside the legal, tax and investment planning from the start.

Why planning early matters
Buying property abroad is exciting, but it is also a financial transaction that crosses currencies, markets and legal systems.
The exchange rate can affect your deposit, your completion funds, your stage payments and your overall budget.
In uncertain markets, that matters.
Global events, energy shocks, inflation and interest rate expectations can all influence currency movement. For international property buyers, the best approach is to plan early, understand the risks and avoid leaving foreign exchange until the last minute.
Because when you are buying overseas, the currency decision can be just as important as the property decision.
