When operational, such distributions should help guide judgements on how overall financial system vulnerability is changing. But the approach should also provide considerable additional information on pressure points within the system and on the channels of transmission and potential contagion. 14 I believe that this broad approach offers an important step forwards in the development of an analytically and empirically robust framework for financial stability work. Of course it is analytically hugely challenging – modelling non-linear tail events with endogenous strategic interactions is always going to be tough! The results will inevitably be subject to major uncertainty. But the approach does start to provide a consistent and coherent framework which should substantially improve the value of top-down stress tests and of risk assessment work. 15 A particular “operational” aim is to use the results to help improve the focus of risk reduction work and crisis management planning, for example through the identification of  BIS Review 81/2007  7  “weak points” in the financial system and through improved assessment of the impact of policy interventions. An important element of risk reduction work is to influence the behaviour of financial firms. “Bottom-up” or firm-level stress-testing practices have developed rapidly in recent years. But one challenge is that, as for the authorities, it is hard for individual firms to gauge the likely “systemic impact” of particular shocks, which takes into account macro and financial system interactions and feedback effects.
When we look at successful examples of technology adoption, it’s not just about state-of-the-art technology. It’s about how you manage the change – especially changes to mindsets. It takes time and effort to convince people that a new technology is worth the cost, the effort or the potential risk. 16. This is often the case with larger organisations, especially official institutions like the HKMA. We set up the FFO in early 2016 precisely to serve as a dedicated agent to drive changes and take practical steps to turn ideas into reality. 17. The FFO has contributed to a number of Fintech initiatives in the past three years – from cybersecurity to supervisory sandbox, open API, the FPS, and the rest of the seven Smart Banking initiatives. But I must stress that the FFO is not working in isolation. Other parts of the HKMA must work alongside it, and of course it must work with the banking, technology and even legal sectors. 18. The FFO has essentially served as the coordination point of this collective effort. This has enabled a “change” mindset to spread throughout our organisation and among our partners. And the result is the impressive Fintech developments we have seen in the last few years. 19. A change agent does not have to come from within. Sometimes, competition is an effective driver for innovation. One good example is the imminent entry of virtual banks in Hong Kong.
