LIBOR Losing Relevance

The London Interbank Offered Rate (LIBOR) is losing relevance. Outstanding LIBOR borrowings have fallen 63% in the past 3 years and it has failed to capture turmoil in the banking sector due to the Euro crisis. Why? Central banks around the world have given banks cheap access to cash, banks have increased customer deposits and banks have huge cash deposits at the Fed due to Quantitative Easing.
