Webull FX Fee: The 0.35% UK Currency Conversion Cost in 2026
Webull charges UK clients a 0.35% foreign-exchange fee whenever your money is converted between currencies, as of June 2026, typically when you buy US stocks from a GBP-funded account. On a £1,000 US-stock purchase that is about £3.50 each way. US-based Webull accounts are USD-only, so no FX fee applies there.

What the 0.35% FX fee is
Webull is a commission-free broker for stocks, ETFs and options, but commission-free does not mean cost-free. For UK clients, the main hidden cost is a 0.35% currency-conversion fee, applied whenever your funds move between currencies, as of June 2026. Because Webull's flagship market is US-listed shares priced in dollars, a UK trader funding an account in pounds will hit this fee the moment they buy a US stock, since the platform must convert GBP to USD to settle the trade. It is worth being precise about geography here: in the United States, Webull accounts operate in dollars only, so there is no currency conversion and no FX fee at all for domestic US investors. The 0.35% charge is specifically a feature of the UK (and other non-USD) offering. If you rarely touch non-sterling assets it may never bite, but for anyone building a US-focused portfolio it is the single most important Webull cost to understand. Capital at risk.
When the fee applies
The 0.35% fee triggers on conversion, not on the trade itself, which is a distinction worth internalising. If you fund your Webull account in GBP and buy a US stock, your pounds are converted to dollars and the fee applies. When you later sell that stock and convert the dollar proceeds back to sterling to withdraw, conversion happens again. So a full round trip, buy in and cash out, can incur the fee twice. What does not trigger it is trading within the same currency: if you were to hold a dollar balance and trade only US stocks with it, you would not repeatedly pay conversion on each trade, only when you move between currencies. Note also that on sells, regulatory fees may apply as a separate, small statutory cost, distinct from the FX charge. The mental model is simple: every time money crosses a currency boundary at Webull UK, budget 0.35%. All figures as of June 2026. Capital at risk.
A worked example
Suppose you are a UK investor with a GBP-funded Webull account and you decide to buy £1,000 worth of a US-listed stock. To settle in dollars, Webull converts your £1,000 and charges 0.35%, which is £3.50. So roughly £3.50 of your £1,000 goes to the FX fee before you own a single share, as of June 2026. If you later sell and repatriate the proceeds to sterling, you pay the 0.35% again on the converted amount, another few pounds depending on the value at sale. On a single modest trade this is small, but scale it up. Move £50,000 into US stocks and the entry conversion alone is around £175. For a buy-and-hold investor making occasional large conversions, that is the number to weigh. For a frequent trader flipping between sterling and dollars, the repeated 0.35% hits add up faster than the headline commission-free label suggests. Capital at risk.
How Webull's FX fee compares
At 0.35%, Webull's currency-conversion fee sits in the middle of the UK market as of June 2026. It is meaningfully cheaper than eToro, which charges around 0.75% on conversion, and undercuts XTB's 0.5%. But it is more than double Trading 212's 0.15%, which is among the lowest available. So Webull is competitive but not the cheapest for FX-heavy investors. Whether the difference matters depends entirely on how much converting you do. For someone making a handful of small trades a year, the gap between 0.15% and 0.35% is a rounding error, and other factors like platform quality, charting and available markets should drive your choice. For someone regularly moving five-figure sums between sterling and dollars, the difference compounds into real money, and a lower-FX broker could save meaningfully over a year. Match the fee to your actual behaviour rather than the headline. Capital at risk.
The other fees to watch: wires and transfers out
Beyond FX, Webull's fee schedule is lean but has a couple of sharp edges worth knowing before you commit. As of June 2026, standard ACH withdrawals are free, which covers most routine cash-outs. However, an outbound wire transfer costs $25, and transferring your holdings out to another broker via the ACAT system costs $75. That transfer-out fee matters if you ever decide to move your portfolio elsewhere, since it is charged by Webull to release your assets. On the reassuring side, there is no inactivity fee and no minimum deposit, so simply holding an account or leaving it idle costs nothing. The practical advice: stick to free ACH withdrawals where possible, avoid wires unless necessary, and factor in the $75 exit cost if you are the type to switch brokers periodically. None of these are unusual for a US-based broker, but they are easy to overlook behind the commission-free headline. Capital at risk.
The bottom line
Webull's 0.35% UK FX fee is fair, sitting below eToro (0.75%) and XTB (0.5%) but above Trading 212 (0.15%), as of June 2026. For occasional traders it is a non-issue; for those regularly converting large sums between sterling and dollars, it is the cost to weigh, and a lower-FX broker could save money. Keep the $25 wire and $75 ACAT transfer-out fees in mind too, especially if you might switch brokers later. Overall, a competitive commission-free platform whose real UK cost lives in currency conversion rather than dealing charges. Capital at risk.
