The pound is posting limited gains against the dollar as investors are cautious ahead of the main events. Political uncertainty is the main driver of the currency and it is unlikely to see much of support until the new PM takes on Brexit saga. The dollar pulled back from the multi-months lows following the Fed comments. The awaited G20 summit will make the biggest impact and decide central bank on the next move.
