Financial speculators are beating their tom-toms with special enthusiasm today over the possibility that the unexpectedly harsh effects of Hurricane Katrina will lead the

Federal Reserve

to pause its campaign of hiking interest rates.

In an interview on

CNBC

, portfolio manager Paul McCulley, who helps Bill Gross steer tens of billions of dollars worth of bond bets at

Pimco

, called Fed action "finished."

Traders took that cue and dived right in to one of the sectors of the market most badly burned by the prospect of higher rates -- the subprime and nonconforming mortgage lenders -- and started driving up shares.

Aames Investment

(AIC) - Get Report

, a subprime home lender based in Los Angeles that saw its stock cut by a third in August, is rebounding as much as 3% today. Likewise, shares of subprime or nonconforming loan issuers

Accredited Home Lending

( LEND) of San Diego and

NovaStar Financial

( NFI) of Kansas City are each up better than 3%.

These moves could all have legs if Katrina does in fact lead the Fed to take a wait-and-see attitude toward the U.S. economic recovery at its September meeting. But it's not a sure thing, of course. Here's one way to think about it, courtesy of veteran Fed watcher Tom Gallagher, analyst at ISI Group in Washington D.C.

  • Start with consideration of the growth impact of Katrina. First, you have a vast loss of income and wealth in the Mississippi-Louisiana area that will be offset only partly by rebuilding, government aid and insurance payments. Then you have the impact on the energy and transportation systems, which are an unmitigated negative shock. Consumer demand nationwide had been a big concern pre-Katrina, but now you also have much higher gas prices and a couple of major cities -- New Orleans and Biloxi -- out of commission for months. (That's much different than your basic Florida hurricane, Gallagher notes, where damage is localized, and people are usually back at work quickly.) Net net, growth is a negative.
  • Next the Fed considers inflation. The supply shock lifts prices, while the demand shock restrains them, Gallagher says. Figure it's a net neutral.
  • Then there's an impact on the financial system. Banking operations in the area have broken down, and shares of local financial services companies like IberiaBank (IBKC) - Get Report are sinking. Over the coming weeks, Gallagher, forecasts, there will likely be a growing number of defaults on consumer, mortgage and business loans. Not good.

While the knee-jerk reaction is to consider the economic impact will be negative, the Fed will probably wish to be more circumspect. If the Federal Open Market Committee were to meet in the next couple of days, Gallagher said, it would likely pause simply because it won't know the magnitude of the demand, supply and financial impacts. But because it actually meets three weeks from now, it has time to assess the damage with more perspective.

So Gallagher's final guess on the probability of Fed moves goes like this:

  • It probably will hike again in three weeks, but let hurricane damage affect its endpoint. It could accomplish that with a statement to that effect following its meeting. He says the Fed has a high threshold for a pause, and may be concerned that one pause would lead the market to assume it is done for the cycle.
  • Or it could start an "extended pause" in September. The reasoning could be that this extreme hurricane's damage does meet the threshold for a halt in hikes, considering the moonshot in oil prices will have the same effect on the economy as it is trying to accomplish anyway.

If there is one pause, there is likely to be more. There's really not much point in stopping for one month. That's the sort of half-measure that the organization has tried to avoid. If so, the August hike may have been the last of Greenspan's tenure. In that context, a pause could be seen as a magnanimous gesture by a retiring hero to a grateful nation. (Or not.)

Meanwhile, back on Planet Wall Street, traders appear to be betting on the pause by pushing up shares most affected by higher rates. The subprime lenders, often reviled by the snobbish market intelligentsia, provide an important service to less-advantaged consumers who wish to buy a house and don't mind spending a little extra in interest and fees to do so. Aames, which pays a dividend of 10%, could easily move all the way back to $9 if this move gets going, while NovaStar could revisit $40 and Accredited would have a shot at $45 or better.

For those who read my piece on

BJs,

I've

updated the column with some additional information from Avalon Research.

Please note that due to factors including low market capitalization and/or insufficient public float, we consider IberiaBank to be a small-cap stock. You should be aware that such stocks are subject to more risk than stocks of larger companies, including greater volatility, lower liquidity and less publicly available information, and that postings such as this one can have an effect on their stock prices.
