in the 1960s and 1970s, and thus the main onshore banking systems, to be recycled back into the economic system while paying interest to the capital's owner, thus encouraging them to keep their capital offshore. They highlight the Eurodollar capital market as particularly important. However, as OFCs developed in the 1980s, it became apparent that OFC banks were not just recycling Eurodollars from foreign corporate transactions, but also capital from tax avoidance (e.g. money being hidden in tax havens), and also from other criminal and illegal sources. Many OFCs, such as Switzerland, had bank secrecy laws protecting the identity of the owners of the offshore capital in the OFC. Over the years, a has weakened the ability of OFCs to provide bank secrecy. Shadow banking, however, remains a key part of OFCs services, and the Financial Stability Forum list of major shadow banking locations are all recognized OFCs. Securitisation OFCs, however, have expanded into a related area to shadow banking, which is asset securitisation. Unlike traditional shadow banking, where the OFC bank needs to access a pool of offshore capital to operate, securitisation involves no provision of capital. OFC securitisation involves the provision of legal structures, registered in the OFC, into which foreign capital is placed to finance foreign assets (e.g. aircraft, ships, mortgages assets etc.), used by foreign operators and foreign investors. The OFC thus behaves more like a legal conduit rather than providing actual banking services. This has seen a rise in large specialist legal and accounting firms, who provide the legal structures for securitisations, in OFC locations. In normal securitisations, the foreign capital, assets and operators can all come from major onshore locations. For example, Deutsche Bank in Germany might lend Euro 5 billion into an Irish Section 110 SPV (the Irish securitisation legal structure), which then buys Euro 5 billion in aircraft engines from Boeing, and then leases the engines to Delta Airlines. The reason why Deutsche Bank would use an Irish Section 110 SPV is that it is tax neutral, and that it has certain legal features, particularly orphaning, which are helpful to Deutsche Bank, but which are not available in Germany. Orphaning poses considerable risks of tax abuse and tax avoidance to the tax base of higher-tax jurisdictions; even Ireland discovered a major domestic tax avoidance scheme in 2016, by U.S. distressed debt funds, using the Irish Section 110 SPVs, on Irish domestic investments.
