Resserrement du crédit
Résumé
A credit crunch (also known as 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).
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 debt when the loans turn sour and the full extent of bad debts becomes known.
There are a number of reasons why 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 central bank suddenly and unexpectedly raises reserve requirements or imposes new regulatory constraints on lending); the central government imposing direct credit controls on the banking system; or even an increased perception of risk regarding the solvency of other banks within the banking system.
