Changing the BoE’s remit now would obviously lead to a rout across the market (I know you’re not advocating changing it right now), so we’re stuck in a bad situation for the foreseeable future.
The problem at the moment is that the government is pushing ahead with a radical fiscal package at the same time as the BoE is facing unprecedented uncertainty as to how and when to unwind QE. The question of how to unwind QE has hung over the market for years - not just in relation to the UK - and most thought it would occur only when fiscal surpluses are being recorded, or at least small deficits, such that the supply of gilts (normal issuance and those sold from the APF) would not overwhelm the market. Obviously that isn’t happening now, and I was surprised that the government pushed ahead with the tax cuts so soon after underwriting utility bills, the cost of which is in theory open ended. I’m not against tax cuts per se, but the timing was wrong in my book.
The other protagonist in this is of course the BoE, which got itself behind the curve in terms of rates, and which is now pushing ahead with large hikes to try to regain credibility. These rate hikes obviously dictate the fiscal outlook via the APF, so both fiscal and monetary policies are in flux and aggravating each other, causing the bigger market reaction. I would think that the BoE is extremely happy with the events of the past week as they’ll be absolved of most of the blame, when in fact they should be coming under severe scrutiny.
