Anyone concerned by the experiments being conducted by various central banks, including the BoE may be interested in this petition, started by Tim Price - a bearish commentator for Money Week:
https://petition.parliament.uk/petitions/164630 Disclosure: I haven't decided yet whether to sign it myself. Limiting the mandate of the BoE may lead to a whole different set of problems down the line. But I do believe that interest rates that are too low and the continued flow of cheap money are not healthy for the future prospects of the economy.
Of course nothing is likely to change as a result of signing this, or any similar petition, but it may at least force a response from the government.
