Analysts pointed out that underlying revenues were down from $14.7 billion to $14 billion and adjusted profits (taking out one-offs) were 14% lower at $5.5 billion.
The rise in pre-tax profits reflected the $1.4 billion reduction in litigation costs and fines from a year earlier, half of which came from much lower payouts to UK customers who were mis-sold products such as PPI.
Chief executive Stuart Gulliver said most of the fall in revenues had come from its retail and wealth management business in Hong Kong, which was hit by the collapse in Chinese stock markets over the summer.
