The $150 billion fiscal stimulus package that's winding its way through the U.S. Congress will not represent a panacea for the U.S.'s economic ills, an economist argued, but it will represent modest good news for one segment -- the beleaguered housing sector.

The fiscal stimulus bill currently under discussion in the U.S. Senate calls for raising Fannie Mae and Freddie Mac's conforming loan limit to $729,750 through 2008 from the current $417,000.

Conforming loans are conventional, fixed-rate mortgages for good credit borrowers that banks make that are eligible for purchase by Fannie Mae (NYSE: FNM) and Freddie Mac (NYSE: FRE). When Freddie and Fannie purchase these loans from banks, it "frees-up" money that the banks can use to grant mortgages to future borrowers, thus expanding the pool of funds available for mortgages.

Economist Steve Affinito told BloggingStocks Thursday that while it's important to underscore that the higher conforming loan ceiling will not eliminate the U.S. housing sector's recession, it is "a critical, essential step in the right direction," in his interpretation.
