Thin liquidity between the two currencies
The cross is built from GBP/USD and USD/JPY, with almost no direct liquidity between sterling and yen. When both dollar pairs move together their amplitudes add — and execution deteriorates precisely then, with spreads widening exactly when the move is strongest.
Why execution worsens as the move grows
Speed is not only opportunity here; conditions worsen at the moment the move is largest.

Check equity indices before entering: they set the direction of this cross more often than the UK economic calendar does. Strong British data will not help on a day when markets are reducing risk. Typical daily range here is 128 pips. News risk and this pair's hours are covered separately.
