Abstract
This paper introduces a theoretical liquidity risk model to explain how the fire-sale price happens by banks' portfolio composition and the liquidity shocks. The model illustrates that the derivatives can serves as Arrow-Debreu securities for banks to share and eliminate the liquidity risks. The shadow banking system serves as the external funds aids banks to absorb the liquidity shocks, and re-enforce their advantage in borrow-short-and-lend-long. The results are helpful to understanding how bank runs among financial institutions occurred during the subprime crisis, and why the $500B subprime mortgage losses could not be fixed by more than $2T government aids, and crashed the prices and led to a frozen market.
