HSBC, Citicorp and Standard Chartered Bank provide the best sub-custody and securities clearing services, according an annual survey conducted by Global Custodian magazine in its 2000 Major Market Agent Bank Review. HSBC has held its position for 12 years, Standard Chartered at least three, while Citicorp entered the top category for the first time this year. The survey measured the quality of service offered by agent banks to their cross-border clients across 24 markets. They also, for the first time, included information provided by domestic clients. Information for the survey was gathered from interviews and questionnaires, over a four-month period.
