I want to know the answer to the following question:
What is the date the active phase of the financial crisis began as a liquidity crisis?
All the background I'm provided with is that "The active phase of the crisis, which manifested as a liquidity crisis, can be dated from August 9, 2007, when BNP Paribas terminated withdrawals from three hedge funds citing "a complete evaporation of liquidity".". Is that enough to answer the question?
