【明報專訊】A year ago, the collapse of Lehman Brothers (an investment bank) triggered a financial tsunami. Governments have since done what is the most radically unconventional ever in intervening in the market. They have, by doing so, averted a global depression. However, while the real global economy does not seem exactly to have recovered, financial markets have been brisk and asset prices have kept soaring. Does that show what has been done to avert a crisis may bring about a new crisis? Governments and investors must watch if that may be the case.
