LCR is a stress test measure,so we cannot use the 2 years low interest rate environment and no correlation at its facevalue. The question says there is movement but in last two years there is no correlation. Since LCR is a stress measure we cannot use 0 correlation in a benign environment as a reason for LCR not impacting is my thesis. If we use 0 correlation as basis it as wrong as the mistake made by risk analysts during 2008 crisis in constant correlation analysis in risk estimation of mbs tranchesbut if the correlation is low meaning people are not motivated to move their deposits then there will be no impact on LCR.
secondly, LCR is a short term measure and no correlation of last two years means things are static.
