Annually, the bank posted pre-tax profits of $18.9bn (£13.2bn) - up 1%, but lower than economists' forecasts.
Adjusted profits for 2015 fell 7% to $20.4bn.
Douglas Flint, Group Chairman, said that "China’s slower economic growth will undoubtedly contribute to a bumpier financial environment".
He added:
"2015 was marked by some seismic shifts in global economic conditions, most notably the continuation of a sharp decline in commodity and oil prices, in part attributable to growing concerns over China’s slowing economic growth. As a consequence, monetary policy remained accommodative throughout the major developed economies and key currency interest rates remained at historically low levels.
"Against this backdrop, the Group’s financial performance in 2015 was broadly satisfactory, with reported profit before tax rising 1% to $18.9bn. On the adjusted basis used to measure management and business performance, profit before tax of $20.4bn was 7% lower than that achieved in 2014, driven by higher costs and credit charges."
Stuart Gulliver, Group Chief Executive, confirmed that the bank has decided to retain its operations in Turkey after a number of offers for the subsidiary were not "deemed to be in the best interests of shareholders".
Gulliver said:
"We have therefore decided to retain and restructure our Turkish operations, maintaining our wholesale banking business and refocusing our retail banking network. This will provide better value for shareholders and continue to allow our clients to capitalise on HSBC’s international footprint.
"We continued to redevelop our businesses in the US and Mexico over the course of 2015. These are important businesses in the context of the wider Group and we are committed to turning them around. An increase in cross-border business across the NAFTA area and improved collaboration between global businesses helped to generate increased revenue."
