European Banking System Remains Fragile

European Bank markets have continued to be unsecured and unbalanced. A survey by the European Central Bank stated that about half of the 105 banks have lent money to other banks without requiring collateral. In an unsecured market, these liquidity conditions have increased heavily, before 2008 this number would never reach above 20% now it is around 90%. Since banks depend on the market to raise money for them, without securing these loans, the market will remain unstable? How should European Banks curtail this problem?
