Bank of England (BoE) is set to go ahead with a new rule to crackdown on banks' capital to lending ratio despite lobbying against the plan. Policymakers said on Tuesday the central bank would introduce a new curb on banks' risk exposure based on their leverage.BoE's Andrew Bailey believes the new rule should be in place as soon as possible. "We have made clear that we will go through these with the public, with the institutions during the course of this month. And we will publish. We will make clear what the outcome of that is," he told parliament's Treasury Committee, according to Reuters.The UK's Prudential Regulation Authority (PRA), which Bailey heads, last month said it would set a leverage ratio of 3.0% for banks, which would limit the amount they can lend relative to their capital.Some have criticised the plan, saying requirements to build up capital levels runs against the government's calls that banks lend more in order to help economic recovery. They also argue that the proposal would penalise low-risk, high-volume businesses like trade finance and mortgage lending.Barclays, which has a leverage ratio of 2.5% after adjustments, warned on Friday that is may have to cut lending if forced to meet the new guidelines.
