The Precautionary Agreement is one such rating device. It serves to boost international confidence in an economy. Another contraption is the Monitoring Agreement, which sets economic benchmarks (some say, hurdles) under a shadow economic program designed by the IMF. Attaining these benchmarks confers reliability upon the economic policies of the country monitored. Financial Assistance Where surveillance ends, financial assistance begins. It is extended to members with BOP difficulties to support adjustment and reform policies and economic agendas. Through 31/7/97, for instance, the IMF extended 23 billion USD of such help to more than 50 countries and the outstanding credit portfolio stood at 60 billion USD. The surprising thing is that 90% of these amounts were borrowed by relatively well-off countries in the West, contrary to the image of the IMF as a lender of last resort to shabby countries in despair. Hidden behind a jungle of acronyms, an unprecedented system of international finance evolves relentlessly. They will be reviewed in detail later. Technical Assistance The last type of activity of the IMF is Technical Assistance, mainly in the design and implementation of fiscal and monetary policy and in building the institutions to see them through successfully (e.g., Central Banks). The IMF also teaches the uninitiated how to handle and account for transactions that they are doing with the IMF. Another branch of this activity is the collection of statistical data - where the IMF is forced to rely on mostly inadequate and antiquated systems of data collection and analysis. Lately, the IMF stepped up its activities in the training of government and non-government (NGO) officials. This is in line with the new credo of the World Bank: without the right, functioning, less corrupt institutions - no policy will succeed, no matter how right. From the narrow point of view of its financial mechanisms (as distinct from its policies) - the IMF is an intriguing and hitherto successful example of international collaboration and crisis prevention or amelioration (=crisis management). The principle is deceptively simple: member countries purchase the currencies of other member countries (USA, Germany, the UK, etc.). Alternatively, the draw SDRs and convert them to the aforementioned "hard" currencies. They pay for all this with their own, local and humble currencies. The catch is that they have to buy their own currencies back from the IMF after a prescribed period of time. As with every bank, they also have to pay charges and commissions related to the withdrawal.
