This growth is primarily accounted for by the ongoing securitisation of mortgage portfolios. In the first six months, Dutch enterprises conducted twelve securitisation transactions. Ten of these concerned mortgages and, in all cases, led to a decrease in the balance sheet total of the securitizing party, the so-termed originator. At present, 19% of all mortgages (EUR 96 billion) in the Netherlands are securitized. In the other two cases, the securitization concerned corporate credits or export credits. The largest securitization transaction in this period was conducted by ABN AMRO Bank (EUR 4 billion).
