As a result, it transfer significant risks to third parties before (such as ABS). So in some cases banks will might make sense for banks to invest in moving from the non-securitization rules to need more capital to securitize assets than to higher-yielding assets during the transition, as the securitization rules. During the Basel II hold them on balance sheet. the cost of incremental capital will be zero. negotiations, the meaning of the term Bank sponsors are expected to continue to significant risk transfer was not clear, except in operate conduits for reasons other than Late adoption Canada (where rules already contained such a regulatory capital arbitrage, but it also seems The industry has raised a number of requirement), whose regulators said that it was likely that there will be a series of conduit complaints about various aspects of the Basel II designed to enable them to ignore sham restructurings over the next few years, as well rules for a number of years, both with the Basel transactions in which no risk was transferred. as an exploration of structured investment Committee and with the EU and member state Most securitization transactions executed vehicles as the preferred mechanism for regulators during implementation. by originators for funding purposes transfer obtaining arbitrage profits.
