There have been many terms tossed around lately stemming from the latest economic and financial news. One of the most popular has been the phrase “a run on the bank”.

What does that really mean?

A run on the bank is really a type of financial crisis that occurs when bank customers rush to withdraw their funds over fears that the bank may go under. Such as with Bear Stearns (BSC: chart, web, Y!), when word got out that they weren’t doing so hot, and you saw the mad rush to sell the stock, dropping the price per share from nearly $100 to under …

The Fed cut its discount rate by 75 basis points, even when the street predicted a 100% chance of a full 100 point cut.

Whats more important though is that Goldman Sachs (GS: chart, web, Y!) and Lehman Brothers (LEH: chart, web, Y!) both reported smaller than expected profit declines, easing fears that the liquidity crisis that sank Bear Stearns (BSC: chart, web, Y!) could spread to other investment banks.

Goldman Sachs finished out 2007 in good shape with shares exceeding analysts predictions.

It seems Bear Stearns (BSC: chart, web, Y!) is in a bit of a pickle. At one point today they were staring their largest one-day percentage drop since the October 1987 stock market crash in the face. Why? Exposure to mortgage securities.

The stock fell 7.4% to $57 but traded as low as $50.48, representing a decline of more than 16%. The last time the Wall Street firm’s shares had a bigger one-day percentage loss than that was Oct. 19, 1987.
