The global financial crisis highlighted the limitations of [[risk-weighted assets|risk-weighted]] bank [[capital ratio]]s ([[regulatory capital]] divided by [[risk-weighted assets]]). Despite refinements over two decades, the weights applied to asset categories did not fully reflect banks’ [[portfolio risk]], in turn increasing [[systemic risk]]. To tackle this problem [[Basel III]] introduced a [[minimum leverage ratio]], defined as a [[bank]]’s [[tier 1 capital]] over an exposure measure which is independent of any risk assessment. | The global financial crisis highlighted the limitations of [[risk-weighted assets|risk-weighted]] bank [[capital ratio]]s ([[regulatory capital]] divided by [[risk-weighted assets]]).

[[Risk-weighting]] is (supposedly) a sophisticated tool, [[leverage ratio]] a blunt one. [[Risk-weighting]] makes a qualitative evaluation of the riskiness of a given asset — apples and pears. LRD applies across the board, to apples and pears equally irrespective of their riskiness. | |||
The aim of the [[leverage ratio]] is to complement and backstop risk-based capital requirements, counterbalancing [[systemic risk]] by limiting risk weight compression during booms. The leverage ratio is therefore intended to act counter-cyclically — being tighter in booms and looser in busts, thereby reducing the probability of crises and the amplitude of output fluctuations. | The aim of the [[leverage ratio]] is to complement and backstop risk-based capital requirements, counterbalancing [[systemic risk]] by limiting risk weight compression during booms.
