A credit crunch (a credit squeeze, credit tightening or credit crisis) is a sudden reduction in the general availability of loans (or credit) or a sudden tightening of the conditions required to obtain a loan from banks. A credit crunch generally involves a reduction in the availability of credit independent of a rise in official interest rates. In such situations the relationship between credit availability and interest rates changes. Credit becomes less available at any given official interest rate, or there ceases to be a clear relationship between interest rates and credit availability (i.e. credit rationing occurs). Many times, a credit crunch is accompanied by a flight to quality by lenders and investors, as they seek less risky investments (often at the expense of small to medium size enterprises).
Causes

A credit crunch is often caused by a sustained period of careless and inappropriate lending which results in losses for lending institutions and investors in

when the loans turn sour and the full extent of
bad debts becomes known.
There are a number of reasons banks might suddenly stop or slow lending activity. For example, inadequate information about the financial condition of borrowers can lead to a boom in lending when financial institutions overestimate creditworthiness, while the sudden revelation of information suggesting that borrowers are or were less creditworthy can lead to a sudden contraction of credit. Other causes can include an anticipated decline in the value of the
collateral used by the banks to secure the loans; an
exogenous change in monetary conditions (for example, where the

Easy credit conditions
Easy credit conditions (sometimes referred to as "easy money" or "loose credit") are characterized by low interest rates for borrowers and relaxed lending practices by bankers, making it easy to get inexpensive loans. A credit crunch is the opposite, in which interest rates rise and lending practices tighten. Easy credit conditions mean that funds are readily available to borrowers, which results in asset prices rising if the loaned funds are used to buy assets in a particular market, such as real estate or stocks.
Bubble formation

In a credit bubble, lending standards become less stringent. Easy credit drives up prices within a class of assets, usually
real estate or equities. These increased asset values then become the collateral for further borrowing.
During the upward phase in the
credit cycle, asset prices may experience bouts of frenzied competitive, leveraged bidding, inducing

Economist
Hyman Minsky described the types of borrowing and lending that contribute to a bubble. The "hedge borrower" can make debt payments (covering interest and principal) from current cash flows from investments. This borrower is not taking significant risk. However, the next type, the "speculative borrower", the cash flow from investments can service the debt, i.e., cover the interest due, but the borrower must regularly roll over, or re-borrow, the principal.
