Large banks are being forced to reduce credit lines in order to shore up capital, as they must deal with subprime debt and other mortgage-related problems. Smaller banks are just now starting to deal with losses on commercial loans due to the economic downturn. That means that they will have to reduce their loan portfolios to meet capital requirements.
This is happening all over the world. Whole countries are imploding. Iceland? What were they thinking? Italian sovereign debt is now suspect, calling into question their ability to meet their deficits.

Just as consumers used debt to buy "stuff" they wanted now, so did businesses, banks, and governments. It powered a huge global growth boom. The Great Unwind will have the opposite affect, softening demand and weakening spending and growth. What leveraging did for growth, deleveraging will take back. It is likely to be a long, Muddle Through trip.
The IMF now projects that the developed world will slow by a collective 1% next year, dragging world growth close to zero. The export growth that has been powered by a cheap US dollar is destined to slow as world demand falls.

The good news? Oil prices are likely to fall even more, which will free up some money to be used in other ways. The ISM data showed that prices paid are falling, making inflation less likely. The US government deficit, under Democratic control, is likely to be $2 trillion in 2009, a staggering number to be sure. Without the pressure of inflation, and with the threat of outright deflation, it may even be that such a deficit can be managed. In the short term, this massive debt will provide a stimulus, lessening the effects of a deep recession.

The sad thing is that our children will be saddled with the debt for a very long time. Hopefully we spend it on things like infrastructure, which will be of some use to them, rather than on an endless stream of consumer stimulus packages that simply add to current debt.

As investors, businesses and employers/employees, we will have to deal with the outcome of a major resetting of consumer spending. Unemployment will rise. Whatever stimulus package is enacted will mostly be used to draw down debt, and not actually spent. Businesses all over the world are going to have to rethink their growth plans to the extent that they were based on ever-rising US consumer spending. Earnings are going to be under real challenge in most industries. This is going to become more obvious as time goes by, and is going to challenge whatever bear market rally can be mounted.
