Not so long ago, it seemed like Alan Greenspan's successor as Federal Reserve chairman would have it pretty easy at first. The current economic climate of solid growth and tame inflation was expected to continue for many months to come.
That seems like a distant memory now that Hurricane Katrina has sent gasoline, heating oil and natural gas prices soaring and crippled major U.S. commerce hubs. At the same time, the housing market looks more fragile than it did before, causing even Greenspan to worry that the real-estate boom could be losing steam.
Greenspan, whose 18-yeartenureends in January, will leave behind a highly regarded and well-respected legacy as a strong inflation fighter. But his skills, and those of the successor President Bush will soon name, will likely be put to the test in the months ahead.
