Clydesdale Bank's owner National Australia Bank has been deemed the 16th safest in the world by Global Finance magazine.

On its website, Global Finance says the ranking was created through an evaluation of long-term credit ratings – from Moody's, Standard & Poor's and Fitch Ratings – and total assets of the 500 largest banks worldwide.

Two UK banks feature in the latest top 50. HSBC ranks 25th, while Standard Chartered is 48th. The list is topped by Germany's KfW.

NAB was ranked safest in Australasia.
