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 crisis played a significant role in the failure of key businesses, declines in consumer wealth estimated in trillions of U.S. dollars, and a downturn in economic activity leading to the 2008–2012 global recession and contributing to the European sovereign-debt crisis.". Is that enough to answer the question?
Answer: no
