BoE's Haldane says looking at options alongside, or beyond negative rates

Andrew Haldane, Bank of England's chief economist, in the UK Telegraph

• says, on negative interest rates, there are other options beyond that, or alongside that, that we're looking at as well
• with QE there is more we can do there on the gilt side and the corporate bond side in principle
• says as we've found from other central banks, you could purchase assets further down the risk spectrum
• says he does not want to imply we're poised on any of those options
• on negative rates, BoE buying riskier assets - says these are something the Bank needs to look at, and are looking at, with somewhat greater immediacy
