A number of world monetary centres, together with London, Hong Kong and Singapore, are overseen by monetary regulators with an goal on competitiveness and development. In a current workers working paper, we develop a theoretical mannequin to indicate that some aggressive deregulation can come up when a number of regulators are centered on development, although not a ‘race-to-the-bottom’: regulators won’t decrease rules to ranges favoured by banks if the prices of monetary instability are massive. To take care of competitiveness and stability of the UK as a worldwide monetary centre, there’s a want for a complete technique which takes into consideration each regulatory and non-regulatory measures. This may occasionally require coordination throughout a number of establishments.
How a lot do monetary regulators care about development?
In 2023, the UK’s Prudential Regulatory Authority (PRA) acquired a secondary competitiveness and development goal to facilitate, topic to aligning with related worldwide requirements, the worldwide competitiveness of the UK financial system (particularly the monetary providers sector) and its development over the medium and long run. The PRA isn’t distinctive in having such a development goal. For instance, the Financial Authority of Singapore (MAS) has a growth goal of rising Singapore into an internationally aggressive monetary centre. Equally, serving to to keep up Hong Kong’s standing as a world monetary centre is without doubt one of the key capabilities of the Hong Kong Financial Authority (HKMA).
To gauge the extent of growth-focus of regulators, we carried out a textual evaluation of 2013–23 annual studies by the Federal Reserve Board (FRB), the European Banking Authority (EBA), the MAS, the HKMA and the PRA to supply a crude measure of how typically growth-oriented phrases are used relative to stability-oriented phrases. Primarily based on this measure, which indexes the EBA’s stage in 2013 as 1, the MAS and the HKMA seem to have been extra development centered – at the least of their printed paperwork – than the PRA, the FRB, and the EBA during the last decade (Chart 1). Our measure additionally detects an uptick of PRA’s development focus in 2023 after it was given its secondary development and competitiveness goal.

What occurs when regulators compete?
What occurs when a number of regulators have a development goal? To reply this query, we developed a game-theoretic mannequin. In our mannequin, regulators in two monetary centres have an goal operate which consists of a weighted sum of the output from monetary intermediation (‘development goal’) and the anticipated loss from financial institution failures (‘stability goal’). The ‘growth-focused’ regulator 2 has the next weight on the expansion goal than the ‘stability-focused’ regulator 1. Regulators set the extent of ‘regulatory stringency’ (parameter t in our mannequin) to maximise their targets: this captures the complete package deal of regulatory and supervisory necessities, together with capital and liquidity necessities, but additionally the intrusiveness of supervisory oversight and the acceptability of various enterprise fashions. Growing the extent of regulatory stringency lowers the likelihood of financial institution failure but additionally will increase the working prices for banks.
Some banks are dedicated to working in a selected nation as a result of it’s engaging for non-regulatory causes. Certainly, regulatory setting is simply one of many many components which determines a metropolis’s rating within the World Monetary Centres Index 36: different components corresponding to taxation, availability of expert employees, and infrastructure additionally matter. However another banks are prepared to maneuver their operations to any nation in response to the relative stage of regulatory stringency. Banks can bluff and fake to be cellular, so the regulators can not observe which banks are really internationally cellular and thus they reply by setting the identical commonplace for all banks.
The extent of regulatory stringency impacts development in our mannequin by influencing the variety of banks drawn to the nation. In flip, these banks help elevated industrial exercise by matching worldwide capital with productive funding alternatives. Internationally cellular banks transfer to nations which permit them to maximise their income, and they also transfer to nations which provide decrease ranges of regulatory stringency. Nevertheless, there shall be a stage of stringency under which income decline: banks don’t like regulatory stringency under this stage as they don’t need to function in a poorly regulated, unstable setting.
As a benchmark we contemplate the next thought experiment. Suppose that regulators are working in a closed financial system through which no financial institution can transfer overseas. On this case, regulators will set the regulatory stringency to maximise the anticipated profit per financial institution by weighing anticipated output towards anticipated price of failure. Transferring to our core evaluation, suppose that regulators are working in an open financial system, the place some banks can transfer overseas. Regulators at the moment are competing with one another, so will set the extent of regulatory stringency to additionally consider its affect on attracting cellular banks. Whether it is set too excessive, not one of the cellular banks will come, so the anticipated output generated by the monetary sector shall be low. However whether it is set too low, the regulator will entice cellular banks however solely on the expense of accelerating all banks’ failure price: so the anticipated price of financial institution failure will rise and the anticipated output is also low.
We name the ensuing equilibrium ‘aggressive deregulation’. It’s a scenario the place a regulator could set the extent of regulatory stringency under its closed-economy optimum stage to draw internationally cellular banks. An excessive model of it is a ‘race to the underside’, which we outline as a scenario whereby the regulatory stringency is pushed to the extent most popular by banks. We present that, though aggressive deregulation can come up, regulators won’t race to the underside to set the regulatory stringency to ranges most popular by banks if the anticipated price of financial institution failures is massive and their mandate, normally set by the federal government, requires them to restrict this price.
What occurs when regulators are given a stronger development mandate?
The subsequent step in our evaluation is to ask how the degrees of monetary regulation will reply when a authorities revises its regulator’s mandate to extend its give attention to development.
We present that, if the growth-focused regulator 2 turns into much more development centered, then aggressive deregulation could also be mitigated. It’s because the stability-focused regulator 1 turns into much less prepared to compete because it expects its rival to compete extra aggressively to safe all of the cellular banks. Numerical simulations in Chart 2 present that the anticipated stage of regulatory stringency supplied by the 2 regulators (on the y-axis) stays pretty steady as regulator 2 turns into extra development centered (as alpha-2 on the x-axis will increase): it initially will increase modestly, then decreases. This means {that a} stronger development mandate doesn’t essentially end in aggressive deregulation.
Chart 2: Anticipated regulatory stringency is pretty steady as growth-focused regulator turns into extra development centered
Nevertheless, aggressive deregulation outcomes if the stability-focused regulator 1 turns into extra development centered. Regulator 1 competes extra aggressively and lowers its common stage of regulatory stringency. The expansion-focused regulator 2 responds to this problem, so it too lowers its stage of regulatory stringency. It follows that aggressive deregulation intensifies and the anticipated stage of regulatory stringency declines. Numerical simulations, in Chart 3, present that as the expansion focus of regulator 1 turns into extra outstanding (alpha 1 on the x-axis will increase), and approaches that of regulator 2, the anticipated stage of regulatory stringency declines.

The technique of the regulators additionally will depend on what number of banks are prepared to maneuver, which will depend on the relative stringency of monetary regulation – and this can in flip rely on non-regulatory points corresponding to taxes and labour legal guidelines which additionally decide the attractiveness of a rustic. If extra banks are internationally cellular, the growth-focused regulator will decrease its regulatory stringency to draw them. However the response of the stability-focused regulator is ambiguous, because it weighs the good thing about attracting a bigger pool of cellular banks towards the price of having to decontrol extra to compete towards the extra aggressive rival.
A worldwide monetary centre wants a complete technique to flourish
Our evaluation has various coverage implications. First, setting world regulatory requirements would assist restrict the extent of aggressive deregulation. Nevertheless, in apply, it isn’t all the time doable to agree on and implement world requirements throughout all dimensions.
Second, setting hierarchical targets, whereby the expansion goal is made strictly secondary to the steadiness goal (as within the case of the UK’s PRA), could possibly be one other method of limiting aggressive deregulation. To make sure that the steadiness goal stays strictly main, regulators may monitor a set of quantitative indicators for its main stability goal.
Lastly, there shall be much less want for monetary regulators to make use of regulatory stringency to draw monetary establishments in the event that they turn into dedicated to staying within the nation as a result of it’s engaging in different dimensions. This requires a complete technique, which takes into consideration each regulatory and non-regulatory measures, to keep up each competitiveness and stability of the UK as a worldwide monetary centre.
