Interest rate differentials barely matter inside a single session

Carry and rate spreads drive currencies over months. Inside a ten-minute scalp, they contribute almost nothing, and arguments about them during a session mostly waste attention.

What matters at that scale is flow, positioning, and reaction to scheduled events. A pair can fall for an hour against the direction of every fundamental argument, simply because a large order is being worked.

The rate story does sneak in through expectations. When markets reprice the chance of a central bank move, short-term flows follow immediately, so the headline about expected rates matters even when the differential itself has not changed.

Keeping a view on the broader picture can help avoid fighting a strong theme at the extremes of the day. But treating it as a trade signal for the next few minutes usually leads to bad entries.

The practical takeaway is simple: use the macro picture to avoid fighting a huge theme, then let price and flow make the actual call.
