An offshore bank is a bank located outside the country of residence of the depositor, typically in a low tax jurisdiction (or tax haven) that provides financial and legal advantages.
While the term originates from the Channel Islands being "offshore" from the United Kingdom, and most offshore banks are located in island nations to this day, the term is used figuratively to refer to such banks regardless of location, including Swiss banks and those of other landlocked nations such as Luxembourg and Andorra.
Wherever you live, banking offshore gives you the opportunity to grow and protect your money in a secure, central location. So you can keep your money in one place while you move around the world. Banking offshore also makes it easier for you to manage your finances in multiple currencies across different countries.
Most expats have a bank account in their home country to manage financial commitments like property payments and school fees. You also need a bank account in the country where you're living to cover things like your rent, utilities and shopping. Banking offshore provides a link between all your banking arrangements, giving you easy international access to your finances and a central home for your money.
