WHAT are the consequences of a world in which regulators rescue even the financial institutions whose recklessness and greed helped create the titanic credit mess we are in? Will the consequences be an even weaker currency, rampant inflation, a continuation of the slow bleed that we have witnessed at banks and brokerage firms for the past year?

Or all of the above?

Stick around, because we’ll soon find out. And it’s not going to be pretty.

Agreeing to guarantee a 28-day credit line to Bear Stearns, by way of JPMorgan Chase, the Federal Reserve Bank of New York conceded last Friday that no sizable firm with a book of mortgage securities or loans out to mortgage issuers could be allowed to fail right now. It was the most explicit sign yet of the Fed’s “Rescues ‘R’ Us” doctrine that already helped to force the marriage of Bank of America and Countrywide.

But why save Bear Stearns? The beneficiary of this bailout, remember, has often operated in the gray areas of Wall Street and with an aggressive, brass-knuckles approach. Until regulators came along in 1996, Bear Stearns was happy to provide its balance sheet and imprimatur to bucket-shop brokerages like Stratton Oakmont and A. R. Baron, clearing dubious stock trades.

And as one of the biggest players in the mortgage securities business on Wall Street, Bear provided munificent lines of credit to public-spirited subprime lenders like New Century (now bankrupt). It is also the owner of EMC Mortgage Corporation, one of the most aggressive subprime mortgage servicers out there.
