Why? Well, it was coming from the IMF.
Egypt would be allowed to borrow $3 billion to help deal with the financial aftermath of February's revolution and would only have to pay 1.5 percent a year (at a time when it borrows internationally at 5 percent). Best of all, Egypt wouldn't have to take any of the politically and socially destabilizing steps (cutting food subsidies, for instance) the IMF usually demands in exchange for its help.
On its face, the deal was good for Egypt and just possibly evidence of an IMF moving away from its neoliberal cookie-cutter formula of "open markets and cut spending" in response to every financial crisis.
But then over the weekend, Egypt said "no thanks." It also stopped negotiating a loan deal with the World Bank. On Saturday Egyptian Finance Minister Samir Radwan said the change was because the interim government's spending plans had been cut. "So we do not need to go at this stage to the Bank and the Fund," he told reporters. (There's an interesting post on all this at the Arabist blog.)
