Banking

Banks have played a key role in the development of Guernsey as an international financial centre.


The first merchant bank was established in Guernsey in 1963 and today there are 23 licensed banks in the island. They represent a range of countries with concentrations of banks with head offices in the UK and Switzerland.

The range of services offered by banks in Guernsey is quite diverse. Some provide retail banking services essential to the local community. Others target the affluent expatriate market, primarily attracting their deposits. There are also banks offering "private banking" services attracting high net worth individuals who seek a total wealth management solution to their financial needs. Banks also support the other financial services businesses operating in Guernsey providing custody, foreign exchange and other banking services to the investment, fund administration, fiduciary and insurance sectors. 

At the last third party review by the IMF in 2010, Guernsey was compliant or largely compliant in all the international core principles.

Approach to supervision

All banks licensed by the Commission are subject to ongoing supervision by the Banking Division which includes:

  • Onsite inspections at the licensee’s place of business 
  • Desk based analysis of regulatory and statistical returns and other relevant data 
  • The submission of annual audited financial statements 
  • Approval by the Commission of firms and individuals who act as controllers, directors or managers of the licensee’s business
  • Notification of significant events or changes within the business
  • Participation in thematic studies relating to banking business and the financial sector, as requested by the Commission
  • Attendance by the Commission at bank supervisory colleges

The GTA University Centre, in consultation with the Commission and finance industry professional and educational bodies, publishes a training matrix for each sector. The Banking Training Matrix is available by following this link to the GTA University Centre website.
