7 per cent since the turn of the year. this will exert a drag on inflation both through lowering import costs and by lowering world demand for uk goods. uk fiscal policy is about to tighten significantly. the average annual reduction in the cyclically - adjusted budget deficit is projected by the obr to increase from around ½ per cent of gdp over the past two years to around 1 per cent of gdp over the next two – and the imf expects the uk to undergo the largest fiscal adjustment of any major advanced economy over the next five years. 30 taken together, these factors suggest that the “ equilibrium ” real rate of interest – the rate needed to keep the economy operating at potential and inflation on target – which was sharply negative during the crisis, will continue to be lower than on average in the past. it also seems likely that the equilibrium interest rate will move only slowly back up towards historically more “ normal ” levels. everything else equal, that suggests a prospective tightening cycle that, once it starts, will be longer and shallower than those of the past. in other words, we expect bank rate increases to be gradual, and limited to a level below past averages. what does that actually mean? the bank of england is around half a millennium younger than magna carta. to put the limited and gradual expectation in historical context, short term interest rates have averaged around 4½ per cent since around the bank ’ s inception three centuries ago, 31 the same average as during the pre - crisis period when inflation was at target. the average pace of not only are the effects sizeable, but, on past experience, they are potentially protracted. the impact of sterling ’ s 25 % depreciation following the onset of the financial crisis on import prices was one factor that contributed to high inflation throughout 2008 – 12. the potential for these effects to be persistent highlights their relevance at the policy horizon. to paraphrase one of my predecessors at the bank of canada, gerry bouey, we didn ’ t abandon the lower bound ; the lower bound abandoned us. see office for budget responsibility ( 2015 ), economic and fiscal outlook, july ; and imf ( 2015 ), world economic outlook. based on data on short term money market rates, starting 1718. see hills, s, thomas, r and dimsdale, n ( 2015 ) “ three centuries of data - version 2. 2 ”, bank of england. bis central bankers ’ speeches tightening since the adoption of inflation targeting in 1992 was

it, the amount of equity that a host regulator requires to be held in a subsidiary over and above the basel minimum may vary according to whether it is part of an “ spe group ” in which the parent / holding company is a source of strength through resolution. where that is the case, it may be possible to shade the subsidiary ’ s capital structure from equity to subordinated debt issued to the holdco. where the group as a whole is not a source of strength in resolution, a subsidiary may need more equity than otherwise. what i am describing would entail some recasting of the key pillars of international supervisory cooperation : the basel concordat, core principles of supervision, and capital accord. 3 there is no such thing as a “ bailin bond ”. bailin is a resolution tool. all creditors can face having to absorb losses. what matters is the creditor hierarchy notwithstanding the clarity in the financial stability board ’ s international standard on resolution, 4 and in the us and draft eu legislative regimes, it is still common for commentators and industry participants to refer to “ bailin bonds ”. 5 as i have said before, “ bailin ” is a verb not a noun. it is a power, not a special kind of bond. like other resolution tools, it can be applied to any kind of debt obligation. what is true is that if bonds are issued from a holding company and the resolution is topdown ( spe ), then those bonds will absorb losses before any creditors of the operating see financial stability board ( 2013 ), “ recovery and resolution planning for systemically important financial institutions : guidance on developing effective resolution strategies ” and tucker ( 2013 ), “ resolution and the future of finance ”. see tucker ( 2013 ), “ the reform of international banking : some remaining challenges ”. see financial stability board ( 2011 ), “ key attributes of effective resolution regimes for financial institutions ”. most recently in chapter 3, “ changes in bank funding patterns and financial stability risks ”, of the imf ’ s october gfsr, which misleadingly refers throughout to “ bail - in debt ”. bis central bankers ’ speeches subsidiaries ; holdco creditors are structurally subordinated to opco creditors. but if the losses are vast enough, then the haircuts imposed by the resolution authority can in principle permeate to any level of the creditor stack. in the case of insured deposits, that means deposit guarantee schemes ( dgs ) suffering losses, as they
