Societe Generale

I'm not into all this high-finance stuff, so can someone help me understand
this, please....

The frog bank lost c.7 billion euros. But their loss must be some other
banks' (or traders') gains.

So why do folk suddenly get frantic and reckon it's the end of the world,
etc.

Why is it regarded as such a problem?

TIA
