Empire was not the main source of Britain's trade, only 24.9% of British imports came from the colonies and 37.2% of exports went to the colonies by 1913. Trade with the Empire remained static but other trade was growing and manufacturing exports, in particular, grew much more slowly after 1870. Growing nationalism in the Empire sometimes led to that trade being damaged e.g. in India, which took 20% of British exports, there were strikes and boycotts of British goods in 1905, showing how this trade which was considered 'safe' was in fact becoming volatile
