When the pound and the dollar move apart on one day, what is driving it?

On some days GBP/USD moves more than the dollar moves against other currencies, or the pound moves against sterling crosses in the opposite direction. That divergence is the most common sign that a pair is responding to a UK driver rather than a dollar one. What moves GBP/USD lists the drivers on each side, which helps separate a sterling story from a dollar story on the same chart.

Members who trade through these days usually check a few things before they decide what is driving the move: whether another dollar pair moved in the same direction, whether a UK or US release landed in the same hour, and whether the move held once the spread settled. The answer changes the trade. A dollar-driven move that fades is a different plan from a sterling-driven move that holds. Market sessions explained helps place each move in the session it happened in.

We would like to hear how you separate them:

• Which check do you run first when GBP/USD moves more than the dollar?
• Do you compare the pair with other dollar pairs, or with sterling crosses?
• How long does a move have to hold before you treat it as a pound story?
• Have you traded a divergence and been wrong about the driver? What did you learn?
