The BONEX Plan was a forced conversion of banktime deposits to Treasury bonds performed by the Argentine government in January 1990.[1]
It was put in place following a 3079,5% hyperinflation in 1989,[2] as heterodox stabilization programs failed.[3] US$3 billion worth of the public's deposits were converted to "Bonex 89" bonds to be repaid in 1999.[4] It amounted to a partial default from the Central Bank and Treasury to commercial banks, who in turn partially defaulted into their depositors.[1]
It was caused by the government's political inability to undertake rigorous fiscal reforms, and a monetary sterilization policy which generated a major 'quasi fiscal' deficit to the Central Bank, further fueling a long-standing high inflation rate.[5][1] Its high debt made the Central Bank lost most of its capacity to carry out independent monetary policy.
A freezing of deposits was also undertaken in neighbor country Brazil at the time, during the Plano Collor.[6]
