These are the best of times and the worst of times to be a financial journalist. The best, because we have a once-in-a-lifetime opportunity to report and analyse the most serious financial crisis since the Great Crash of 1929. The worst, because the newspaper and television industries are suffering, not only from the shock of a recession but also from the structural shock of the internet revolution.

Now comes a third shock. The financial media are accused of missing the global financial crisis. Asleep at the wheel. Head in the clouds. No cliché has been left unturned as reporters, commentators – yes, even editors – have been castigated for failing to warn an unsuspecting public of impending disaster. Do these charges add up? To paraphrase the killer question from the Watergate hearings: what did the press know and when did it know it?

First, by way of mitigation, journalists were not the only ones to fall down on the job. Political leaders were happy to break open the champagne at the credit party; many lingered long after the fizz had gone. Regulators in the US, UK and continental Europe all failed to identify and contain the risks building within the system. Many economists, too, fell short. Only a few – such as Nouriel Roubini, now celebrated as the thinking man's prophet of doom – identified pieces of the puzzle, even if they failed to piece them together.
