JPMorgan’s international private bank chief executive Adam Tejpaul doesn’t have much to complain about. The go-to bank for some of the world’s richest people has grown significantly outside its home market of the US. 

In Europe, where the US lender has offices in countries including Switzerland, Italy, France, Germany and the UK, asset growth has been well above 10% in recent years — which Tejpaul says is double the level of some of its biggest Wall Street competitors.
