GREENSPAN: WELL I THINK THE BIG SURPRISE AT THE MOMENT IS THE EXTRAORDINARY PRESSURES COMING FROM THE FINANCIALS THAT THE AMERICAN ECONOMY HOLDING UP RATHER WELL ACTUALLY. INDEED IF YOU LOOK AT THE GLOBAL CONTEXT IT IS EVEN MORE IMPRESSIVE. ONE PF THE REASONS OF COURSE IS THE FACT THAT WHEN THE CRISIS BEGAN JUST ABOUT A YEAR AGO THE NONFINANCIAL CORPORATE SECTOR WAS IN EXCEPTIONALLY GOOD SHAPE BALANCE SHEETS WERE SUCH THAT BORROWING REQUIREMENTS WERE MINIMAL AND INDEED THEY WEATHERED VERY SIGNIFICANTLY MUCH OF WHAT HAS CREATED A HUGE PROBLEM IN THE FINANCIAL SYSTEM AND ONLY RECENTLY IT IS BEGINNING TO FEEL THE PRESSURES. THE PROBLEM UNFORTUNATELY IS THAT THE FINANCIALS HAS GONE A WHOLE YEAR NOW WE HAVE HAD HUGE AMOUNTS OF LIQUIDITY GENDERED BY CENTRAL BANKS AND IT IS GETTING INCREASINGLY EVIDENT THIS IS A ONCE IN A CENTURY TYPE OF PHENOMENON. IT IS NOT THE STANDARD LIQUIDITY CRISIS THAT WE HAVE SEEN IN THE PAST ITS VERGING ON THE ISSUE OF SOLVENCY AND THE REASON WE KNOW THIS IS BASICALLY WHEN THE FOR EXAMPLE IN BRITAIN WHEN NORTHERN ROCK WAS BAILED OUT WITH SOLVERN CREDIT THAT THE SYSTEM STABILIZED AND WE WERE IN VERY HAD A VERY MAJOR PROBLEM PRIOR TO THE BEAR STEARNS BUYOUT BUT ONCE SOLVERN CREDIT WAS SUBSTITUTED FOR THEIR CREDIT THAT TOO STABILIZES. BUT ITS VERY CLEAR FROM THE SPREADS THAT WE SEE AND FOR EXAMPLE LIBOR AND CREDIT DEFAULT SWAPS FOR THE FINANCIALS THAT WE HAVE NOT GOTTEN CLOSURE YET AND IT IS GOING TO TAKE A WHILE AND I THINK PAUL KNOWS BETTER THAN I HAVING HEARD ME SO OFTEN ON THIS ISSUE IT'S ESSENTIALLY FUNDAMENTALLY THE PRICE OF HOMES IN THE UNITED STATES, WHICH ARE OF COURSE DETERMINING WHAT THE EQUITY IS IN HOMES HERE. AND THEREFORE, WHAT THE ULTIMATE COLLATERAL OF THE MORTGAGE-BACKED SECURITIES IS PRETTY MUCH AROUND THE WORLD. AND WE'RE STILL NOWHERE NEAR THE BOTTOM OF THE HOME PRICING, AND WE ARE LOOKING FOR THAT AS THE CRITICAL STATISTIC WHICH WILL CREATE A BALANCE FUNDAMENTALLY IN THE ECONOMY. AND UNTIL THEN I HOPE WE CAN GET SUFFICIENTLY STABLE STOCK PRICE BECAUSE THERE IS THE FUNDAMENTAL SOURCE OF CAPITAL FROM WHICH WE GET THE ABILITY TO RECAPITALIZE A GOODLY PART OF THE FINANCIAL SYSTEM, WHICH SURELY NEEDS IT.
