PROPUESTAS SOBRE GRAVAMEN DEL SECTOR FINANCIERO
Carlo Cottarelli, Director del Departamento de Asuntos Fiscales del Fondo Monetario Internacional ha publicado recientemente esta contribución al debate:
"Incidentally, as a first step, we tried to figure out how much the recent crisis has cost governments in terms of the direct support they provided to the financial sector. The answer is: so far, about 2.7 percent of GDP for the group of advanced G-20 countries. More for some, less for others – including most emerging market countries.
That’s a sizable sum, but the risks during the crisis were even larger, with guarantees and other contingent liabilities averaging around 25 percent of GDP for the advanced G-20. And all that ignores indirect fiscal costs caused by the recession and (to a lesser extent) stimulus measures—which is causing a surge in public debt—and, perhaps most cruelly, of all, a cumulative loss of output of around 27 percent of GDP.
The Financial Stability Contribution would start as a simple levy on some balance sheet (and, possibly, off-balance sheet) variables, but then be refined to strengthen the link with each institution’s contribution to systemic risk—giving them some incentive to reduce it. It would be permanent (to keep that beneficial effect at work, at least until regulatory solutions are felt to have done enough) and paid by all financial institutions (because they all benefit from the greater financial stability the resolution mechanism provides).
Whether the revenue from such a charge should be treated just like other tax revenue or instead feed an earmarked fund to help with resolutions is secondary. The fiscal impact is the same (assuming of course, other policies are not affected by whether there is or not an earmarked fund): the government has to sell fewer bonds on the open market, either because it has more tax revenue or because it has a captive customer in the fund. The main argument for a fund is that it could provide more assurance that the agency in charge of resolution has ready access to the resources it needs."
