For most of the last seven years, Americans have been happily pulling money out of there homes in 'cash-out' refinancing of their 1st mortgage or acquiring home equity loans. To a large part, people did put that money back into their homes in various home improvement projects, but another large part of that money was used for purchases.
Now mortgage lenders are pulling back on what they allow to be lent on a home and they require better credit then they did before. So if the home equity ATM machine is closed, what's a consumer to do?
Credit card balances increased
12% and 8% during May and June.
Well if one form of credit is unavailable, then let's just move on to another. Since overall spending was flat, but credit card balances increased, it's reasonable to assume that people are still using credit to live beyond their income means. Gradually the collective balances on these credit cards will reach their maximum and then borrowing on cards will end.
When credit card borrowing stops then spending being supported by those cards will stop too. Either people will find another form to debt to get into or spending will begin to fall.
When spending falls you run the risk of a recession, which in turn usually leads to interest rates to fall, which leads to more borrowing. A relatively simplistic explanation of what economists and the Fed refer to as an economic cycle.
The problem is, once you've racked up huge amounts of debt, are you able to borrow again to keep the cycle going? If mortgage debt and the housing market were trouble, what happens if Americans lose the ability to spend like they have because they're so deep in debt?
