On the basis of no arbitrage principle, the expression of rate of return of securities backed by letters of guarantee is put forward.
In order to study the relationship between the rate of return of securities and other influential factor in the model, a simulation experiment is designed.

But residents reached by phone described scenes of mass flight and street barricades hastily built by the people to defend against the return of security forces.
