The service is called Barclays Wealth iInvest. It is available to UK non-domiciles, UK expats, foreign nationals and residents of Jersey, Guernsey, the Isle of Man and Gibraltar, who have a minimum of £50,000 (around $81,262) to invest.

According to its marketing literature, Barclays Wealth said that “international investment advisors will provide clients with expert advice to help them build bespoke portfolios that are tailored around their individual investment profile”.

The product rollout highlights how private banks are increasingly positioning their business to cater for clients living outside their country of origin, despite, or possibly because, of a rising regulatory and tax compliance burden on expats.

Barclays Wealth iInvest clients can place money in products that invest in stocks, bonds, commodities, exchange-traded funds, managed funds and structured products.
