Euribor rate, the key interbank lending rate among euro zone banks, slipped to the lowest level in 21 months on Tuesday on the back of liquidity pumping by the ECB since last year.

The three-month rate, the main gauge, edged to 0.764%, moving downwards to the all-time low of 0.634% recorded in early 2010. By the same token, the 6-month and 12-month rates plummeted to 1.061% and 1.402% respectively.
