What is the difference between a credit crisis and a crisis of debt / or liquidity?

I think the term "credit crisis" refers to to the relative unavailability of new credit for individuals and businesses.


A "crisis of debt" refers to individuals and businesses carrying unsustainable debt loads (at some point they won't be able to pay it back).


A "liquidity crisis" refers to the unavailability of cash for businesses (to pay debts among other things) and for banks (to lend money.


So a crisis of debt can lead to a "liquidity crisis" which in turn can lead to a "credit crisis".
