At 31 March 2019, it is estimated that a general increase of 100 basis points in interest rates, with all other variables held constant, would increase the Group and the Institute’s surplus and general fund by approximately HK$527,388 and HK$519,180 respectively (2018:HK$475,050 and HK$470,794) so far as the effect on interest-bearing financial assets is concerned.
