Secondly, in Chile banks cannot hold substantial off-balance-sheet positions, because the General Banking Act expressly indicates what kind of firms the banks may establish, such as mutual fund administrators or securitizing firms. These firms, that the law terms affiliates, must have a single line of business and are banned from investing in other companies. In addition, banks must submit their consolidated financial statements on a monthly basis. Moreover, banks may not take positions in credit derivatives, and face other restrictions regarding the operation of derivative instruments. In particular, to operate with interest rate or foreign exchange rate options, banks must undergo a thorough test by the SBIF, while holding uncovered positions in the balance sheet are costly in terms of capital requirements. But not only regulators and policy-makers learned the lessons from our financial crisis. Enterprises did too. Thus we haven't seen the massive currency speculations where so many firms in the emerging world were involved through the use of exotic derivatives that were not only complex but also very difficult to price. 10  In De Gregorio (2001), I discuss these points in connection with the first intervention period of 2001, and in De Gregorio (2006) I do so in the context of inflation targets and financial stability. 6  BIS Review 150/2008  In the present juncture we still face a severe inflationary challenge.
As a matter of fact, whenever accelerated growth in credit and money aggregates occurs simultaneously with soaring asset prices and loose lending standards, increased inflation becomes very likely over the three years that follow (Roffia and Zaghini, 2007). 8 In this context, one can argue that an increase in lending with inflation prospects can be fought with a tightening of monetary policy. However, if the boom was triggered by lack of regulation or supervision, monetary policy tightening by itself could probably be ineffective – or even counterproductive – if the financial system is weakened because of excessive risk taking. Thus, financial regulation plays a major role in granting financial integrity. At the beginning, regulation focused on the strength of individual institutions. However, the tensions we are seeing now exemplify, once again, how individual fragility may quickly evolve into systemic problems. The interrelationships among financial institutions and the proper operation of the markets where liquidity is traded are essential ingredients of a market economy, but these characteristics are also the channels of financial contagion, as recently seen. So it is crucial to have a systemic vision, not only from the perspective of how the different institutions relate to each other, but also how the different types of financial and operating risks are intertwined, creating potential vulnerabilities. The Financial Stability Reports that many central banks put together periodically – including us – seek to evaluate the resiliency of the system as a whole to large disruptions, by carrying out stress tests.
