What’s the purpose of IMF’s calling for the government to take further action?

The International Monetary Fund has told governments across the world that further action is needed to help return the global financial system to stability. In a fresh estimate of the scale of the problem, the IMF says global losses on toxic assets could total four trillion dollars.
    This report does identify what it calls some early signs of stabilization in financial systems, but there are not many of them. And the IMF says further action will be needed if they’re to be sustained. In two key areas, it says that progress by governments has been piecemeal and reactive, dealing with the problem assets held by financial institutions and how to handle banks that need extra capital.For that problem the report says temporary government ownership may sometime be necessary.
