For a British national living in the UAE in 2026, a useful starting point is the currency you will eventually spend the money in. While you live in the UAE, dollars are close to your home currency because the dirham is pegged to the US dollar. If you expect to retire to the UK, sterling costs later in life may justify building sterling exposure over time, and many expats hold both.

Why the dirham peg matters

The UAE dirham has long been pegged to the US dollar, and the Central Bank of the UAE has publicly reaffirmed its commitment to the peg. In practice this means your salary, rent and school fees move with the dollar. Holding dollar assets while you live in the UAE limits exchange rate risk on day to day spending and short-term goals, although no peg can be guaranteed indefinitely.

That changes when your spending shifts elsewhere. A pension, a UK home or university fees in pounds are sterling costs. Euros may matter more if you plan to retire to Spain or Portugal.

Match currency to the goal

A practical approach is to label each pot of money by its purpose and likely currency:

  • Emergency fund and near-term UAE costs: often dirhams or dollars.
  • UK property purchase or school fees in pounds: sterling may make sense, especially as the date gets closer.
  • Long-term retirement money: consider where you expect to live. If that is uncertain, a mix may reduce the risk of being badly wrong.

Exchange rates can move a lot over long periods. Matching assets to future spending may reduce the chance that a currency swing cuts into what you can afford. Reviewing the split every few years, as your plans change, can also help.

Currency of the account versus currency of the assets

An account in sterling does not mean the investments inside are sterling assets. A global equity fund priced in pounds still owns shares in companies around the world, many of them in the US, and its value in pounds will move with the dollar too. Some funds hedge currency back to a base currency, which reduces this effect, usually at a cost.

So the real question is your underlying currency exposure, not just the label on the account or fund.

Watch the US tax angle

Some expats move into dollars by buying US-listed shares or funds directly. For someone who is neither a US citizen nor US resident, that can bring US tax issues:

  • Dividend withholding. The IRS says most US source income paid to foreign persons, including dividends, is subject to 30% tax unless a treaty or specific rule reduces it. There is no US income tax treaty with the UAE.
  • Estate tax. Shares in US companies are US situs assets for US estate tax. Where a non-resident non-citizen's US situs assets exceed USD 60,000 at death, the estate must file a US estate tax return. Whether tax is actually payable then depends on the taxable estate, the USD 13,000 credit, any treaty relief and assets excluded or treated specially. A broker or fund administrator may restrict access while estate-tax documentation is resolved.

Dollar exposure can often be held through non-US funds instead. If you may return to the UK, the UK reporting fund status of any offshore fund also matters for tax later.

Illustrative example only, not a real client. Emma lives in Dubai and plans to retire to the UK in 12 years. She has USD 400,000 invested. She keeps USD 50,000 in dollars as an emergency fund and holds the remaining USD 350,000 in global investments. Over the years before retirement she gradually increases her sterling exposure, so that by the time she moves, most of the money she expects to spend in the UK is less exposed to a sudden fall in the dollar against the pound. The example ignores costs, hedging and tax.

Common mistakes

  • Converting everything into one currency on one day.
  • Assuming a sterling-priced fund has no dollar exposure.
  • Buying US-listed assets without checking withholding and estate tax.
  • Ignoring where you will actually spend the money in retirement.
