My initial reaction was excitement – what a time to be observing Wall Street for a living! This steadily gave way to bafflement, fear and finally, after the US government's $85bn (£48bn, €60bn) bail-out of AIG, anger.
I was pleased that Hank Paulson, the Treasury secretary, heeded my advice (OK, that of others too) and refused to rescue Lehman Brothers. Guess what? The world did not end on Monday, even if the stock market dropped, and on Tuesday, the Federal Reserve was also defiant.
Its unanimous decision not to bow to market fears and cut interest rates was greeted with boos on the New York Stock Exchange floor. But the stock market took the medicine and went on to rally again.
