GBP/USD spreads compared across ten different brokers

I wanted to find out which broker has the lowest spreads on GBP/USD. So I ran a little experiment of my own.

Rather than just reading the headline spreads, or the “GBP USD from XXXX” adverts, I figured the best way was to do a little broker spread test for myself.

So I loaded up ten CFD or spread betting brokers, squashed them all onto one screen and took a screenshot of all of them at once.

That way, it mimics a typical trader’s flow, right?

You see a pattern setting up on the chart, load up your platform and place a trade. No one is waiting for the spread to narrow… if you see an opportunity, you want to take it.

Lowest GBP/USD Spread: My Method

So that’s what I did.

On Tuesday 25th August 2026, I checked all the spreads at the same time,

I made sure we had nothing unusual going on, like some sort of wild market, imminent economic data, or something else that could affect price action.

In fact, it was just a typical Tuesday afternoon in Sterling.

I selected these brokers:

  • IG
  • CMC Markets
  • Pepperstone
  • City Index
  • Plus 500
  • FXCM
  • Capital.com
  • Oanda
  • Forex.com
  • SpreadEx

Lowest GBP/USD Spreads

  1. Pepperstone 0.8 pips
  2. SpreadEx, CMC, FXCM and IG 0.9 pips
  3. Capital.com and Oanda 1.3 pips
  4. Plus 500 1.4 pips
  5. Forex.com on 1.5 pips
  6. City Index 1.7 pips 
CMC 0.9 pips spread on GBP/USD
IG 0.9 pips on GBP/USD
FXCM Variable GBP/USD Spread 0.9 pips
FXCM Variable GBP/USD Spread 1.0 pips
FXCM Variable GBP/USD Spread 1.2 pips

So, Pepperstone had the lowest GBP/USD spread in our August check at 0.8 pips.

And this isn’t just a one-off result.

Pepperstone has recorded the lowest or joint-lowest GBP/USD spread in every monthly check we’ve run since May 2026… four consecutive checks.

It was joint-lowest at 0.9 pips in May and June, then outright lowest at 0.8 pips in July and August.

If you want to explore these spreads for yourself, you can (and should) do your own due diligence. Pepperstone’s GBP/USD spreads

Remember that spreads can change, different times, under different market conditions or just a commercial decision by the broker. They often look at competitors and adjust to stay competitive. 

What’s important is tight spreads on the markets you specifically like to trade. Not headline stuff, but real world…

I also did this same experiment on other markets:

Spread comparison pages: FTSE, DAX, DOW, Nasdaq, S&P 500, Oil, GOLD, EUR/USD and USD/JPY.
