The second task of macroprudential policy is to manage structural risks, or cross-section risks, which could for instance mean that close links between different parts of the financial system at any given time will affect the risk of a crisis affecting the system as a whole. Here, I will primarily focus on the cyclical dimension of macroprudential policy. However, it is not so easy to draw any clear boundary between structural and cyclical problems on the financial markets, just as in other areas, such as the labour market. 1  2  For a few examples, see Geanakoplos (2009), Aikman, Haldane and Nelson (2010) and Borio (2012). BIS central bankers’ speeches  In Figure 1, the red line represents the normal cyclical fluctuations in the economy, the business cycle. The second curve in the figure represents the financial cycle. As I noted, the economic cycle and the financial cycle need not coincide, but can develop differently. Often, the financial cycle is assumed to have a lower frequency, fluctuate more slowly, than the business cycle, as illustrated in the figure.2 Links between the financial cycle and the business cycle can create problems A situation where both cycles definitely coincide is when the financial cycle shows a rapid downturn, as at the end of the figure. This was what happened in many countries during the financial crisis, and in Sweden during the crisis at the beginning of the 1990s.
Joseph Yam: Competition and cooperation among global and regional financial centres Speech by Mr Joseph Yam, Chief Executive of the Hong Kong Monetary Authority, at the Concurrent Panel Sessions of the Lujiazui Forum, Hong Kong, 9 May 2008. *  *  *  There are two points that I would like to make. First, given that many jurisdictions claim to be or wish to develop as international financial centres, we need to be clear about what actually defines an international financial centre. We in Hong Kong have given much thought to this, principally because Article 109 of the Basic Law of the Hong Kong Special Administrative Region requires that "The Government of the Hong Kong Special Administrative Region shall provide an appropriate economic and legal environment for the maintenance of the status of Hong Kong as an international financial centre". We obviously do not wish to fail in this legal responsibility. I do not believe that being the nth largest foreign exchange trading centre or the presence of many of the largest international financial institutions are good definitions for an international financial centre. Indeed, with the advancement of information technology, there may be a tendency for the market place to migrate into cyber space. In my opinion, an international financial centre is a centre in which the function of financial intermediation, which is so important for supporting economic growth and development, takes place on an international dimension.
