Central Banks – juggling interest rates and inflation

Low inflation is dampening the effects of low interest rates and central banks are happy to let this happen

As guardians of the economic recovery and a bulwark against inflation, central banks have a tough juggling act to maintain.  This is made even more difficult as priorities shift from getting the economy moving again to keeping an eye out for inflation.  The consequences of this can be seen in central banks’ tolerance towards low inflation with low interest rates proving less helpful as prices remain depressed.  Central banks are letting this happen due to inflation being one ball that central banks dare not come close to dropping.

Too many balls in the air

Central banks have a lot of balls in the air to watch with their remit including managing the price level as well as ensuring stability in the financial markets (and maintaining employment levels in the US).  The number of balls has increased as monetary policy has become the main way to bolster the economy with governments in many countries refusing to use fiscal policy.  But it is inflation that typically remains the main focus of central banks. 

The aversion to inflation was put to one side amid the turmoil of the global financial crisis.  Efforts to prop up the money supply through quantitative easing would have normally also lifted prices but this did not stop central banks taking bold action.  As the threat of crisis has receded, so have measures by some central banks to help out with the economy.  This shift has been made more pronounced due to low inflation as depressed prices strip away some of the positive effects of low interest. 

Juggling priorities  

The rate at which prices are rising affects decisions made by companies on whether to borrow money.  Higher inflation makes low interest rates more attractive to businesses as any products purchased today will be worth more in the future making it easier to pay off debts.  The opposite is also true and flat prices will prompt some business putting off plans to borrow and invest.  The harm done by low inflation is even more pervasive if it is a reflection of a weak economy which seems likely. 

By not doing more to keep prices ticking upwards, central banks are consenting with some of the potential effects of low interest rates being taken away.  It is like a hike in interest rates without interest rates actually having to rise.  It is a sign of how much central banks worry about prices rising too fast that this is happening despite the economic recovery still lacking momentum and inflation close to zero.

Don’t douse the economic recovery

The various roles of the central bank can make it seem as if they are required to juggle fire and water at the same time.  Much has been left to central banks in the aftermath of the global financial crisis which has often resulted in monetary policy being pushed too far.  Central banks were never meant to take such an active role in managing the economy.  A return to their less controversial role of keeping a lid on inflation will come as a welcome relief.  It is, after all, their record on inflation that central banks will often be judged. 

However, it is still too soon to move against the potential threat of a jump in prices.  There is still scope to leave interest rates at their current low levels with other measures such as macroprudential policies available for sectors, such as the residential property market, where lending is getting out of hand.  There is a point in every juggler’s routine where everything seems set to come crashing down – let’s hope that this does not happen due to a premature hike in interest rates.

Central Bank – Emperor's New Clothes

With the myth of its power having been shattered, central banks need to get nasty to win back respect

Central banks are looking a bit naked as if stripped of their power.  Previously, central bankers such as Alan Greenspan were held in awe and ruled over the hearts and minds of investors.  This position of power stemmed from the perceived ability to soothe the fire-breathing financial markets.  Yet, the global financial crisis and its aftermath have shown this to be but a myth.  Part of the problem was that central banks wanted to be liked and keep investors onside.  With its generosity proving its downfall, the naked emperor may need to stop being so nice.

Pretenders to the throne

This fall from grace has happened swiftly.  The powers of central banks reached their peak just before the crisis hit.  Quick to blow their own trumpet, economists talked of a “Great Moderation” – a prolonged period of steady and stable economic growth coupled with low inflation.   Central banks had also shown themselves willing to step in during moments of strife and prop up the stock market.  This won them a strong following among investors who could be sure that central banks would send in the cavalry if there was trouble. 

The proverbial crown slipped and fell dramatically with the global financial crisis.  Not only were central banks proved to be not suitable guardians of the economy but their capacity to rally at times of trouble was limited.  Low interest rates and quantitative easing offered little respite from the plague eating away at the economy.  The potency of central bank policy has been eroded as its primary source of power, the ability to print money, does not mean much in a world awash with money.

The problem was exacerbated by central banks not having the freedom to act as their almighty reputation might suggest.  Part of this was due to internal restraints such as a chronic (but misplaced) fear of inflation.  Such worries about rising prices keep central banks from unleashing their full firepower when faced with crisis.  In addition to this, politics also often acts to stifle central banks.  Germans’ heightened aversion to inflation has kept the European Central Bank from doing more.  The Federal Reserve has also had to be mindful that its actions did not draw ire from Republicans who are typically hostile to any government intervention. 

Cursed by hubris

It also became obvious with hindsight that central banks may have built their dominance on a dubious myth.  The “Great Moderation” may have just resulted from good luck rather than good management.  It is easy to keep inflation down when cheap goods are flooding in from China while money was cheap as China was sending a considerable portion of its earnings as reserves and sending it back to the US.  Yet, the misplaced belief in the rule of central banks over the economy lead to ignorance of risks that central banks thought they had slayed. 

Central banks were happy to live off this aura while also being generous in its dealing with investors.  Yet, this kindness turned out to have a cruel twist with the support shown by central banks to financial markets sowing the seeds of crisis.  Although lauded at the time, the reign of Alan Greenspan has instead been shown to be like a king trying too hard to please his subjects.  Over this period, the Federal Reserve kept interest rates too low while investors made merry amid a booming stock market.   

Better to be feared than loved

The unruly nature of financial markets coupled with the flood of cash sloshing around in global finance means that a guiding hand is needed more than ever.  Having been knocked from their high towers, central banks have to restore some assembly of order in a world where the pull of its ability to print cash is diminished.  It may be best to follow the words of Machiavelli, a renaissance philosopher who theorised on power struggles in Medieval Italy, in that it is better to be feared than loved. 

In this vein, if it was a need-to-be-loved that got central banks, and the rest of us, into trouble, it might be time to get nasty.  Taking a harsh line against any potential distortions in the economy (using macroprudential policies) would win more respect than being too friendly.  To rule with a firmer fist seems a better fit at a time when the consequences of financial excesses are so pertinent.  This would help to usher in a more peaceful period if combined with greater regulation to keep the banking sector from getting out of hand.  More stability may even get investors to appreciate the value of tough love.  

Interest Rate Hike – Easy on the Brakes

The Bank of England threatens to be too heavy on the brakes with higher interest rates and the economic recovery may stall as a result

Tinkering with complex machinery is tricky as changing one thing may have unintended consequences elsewhere.  This also applies to the economy.  The prospect of having to raise interest rates at a time when the economic recovery is still fragile is daunting enough.  Yet, there is a number of moving parts of an economy linked with interest rates which could throw an extra spanner in the works – one concern is that higher interest rates will push up the currency and hurt exporting firms.  This may push central banks to use other monetary policy tools to bide their time.

Complicated piece of machinery

What we refer to as the economy is the accumulation of an incredibly intricate multitude of monetary transactions in which we all are a small part.  In comparison, monetary policy is rather basic relying mainly on the lever of interest rates with extra bells and whistles, such as quantitative easing, added only when needed.  Monetary policy has been exceptionally loose but has still struggled to get the economy moving again.  These expansive polices cannot stay in place for ever and there are growing calls for interest rates to be raised off record lows. 

Interest rates normally affect the economy through the costs involved with taking out a loan.  But this is not the only route of influence.  One example is how higher interest rates will attract in money due to a higher pay-out for savings and this extra cash coming into the economy will push up the value of the currency.  A strengthening currency will adversely affect firms exporting to other countries as prices for their goods typically must rise and this risks putting them at a disadvantage relative to competitors. 

The potential for this is larger when one country moves to tighten its monetary ahead of its peers.  Such is the predicament facing the UK as the Bank of England contemplates the possibility of raising interest rates sometime in the next six to twelve months.  The mere expectation of this has propelled the pound higher relative to other currencies and may put further upward pressure on the pound if interest rates are predicted to rise faster than elsewhere. 

This problem comes about due to the freedom of money to chase around the globe after the best return.  Financial firms have made of most of moving cash around using strategies such as the carry trade – borrowing in a currency with a low interest rate and changing the money into a currency where the interest rates is higher.  This is just one way of how excess liquidity in global markets can work to distort exchange rates relative to the actual physical economy.

Warning lights flashing

Normally higher interest rates are used to slow an overheating economy and a stronger currency would help with this.  Yet, the upcoming hikes to interest rates have the goal of returning monetary policy to normality – a state where interest rates and the rate of growth in the economy are roughly equal.  An accompanying rise in exchange rates therefore acts as a further obstacle to economic recovery which is not intended or desirable. 

The weak recovery means that the UK economy is not quite ready for the double whammy of higher interest rates and a stronger pound.  The effects of both may be benign considering the lower rates of borrowing among businesses and sluggish demand for exports from markets such as Europe.  But there is still the potential for a rise in interest rates to put the economy in reverse at a time when the economy is gearing up for recovery. 

The main issue behind calls for tighter monetary policy is a buoyant housing market.  Yet, the Bank of England has a new range of tools to deal with this such as caps on mortgage lending.  So there is room to wait for other countries, most significantly the US, to catch up in terms of interest rates.  With the threat of waiting too long to act mitigated by housing market measures, it is the downside of braking too soon that the Bank of England should watch out for.

Monetary Policy – Surgery Needed

Current monetary policy is still primitive and will remain so without making use of new measures such as macroprudential policies

Monetary policy has come a long way but it is still in its initial stages of development.  Serious shortcomings mean that the tools of monetary policy are still rudimentary just as those of medicine were crude in the past.  In the same way that leeches would be prescribed for every ailment in medieval times, central banks have tended to rely solely on interest rates to manage the economy.  The tendency to “reach for the leeches” is still with us even though the global financial crisis has highlighted the flaws inherent in this approach and a range of new techniques for managing the economy have been made available.

Learning some hard lessons

Doctors often did more harm than good in antiquity due to a lack of understanding of the workings of the human body.  With our knowledge of the economy also deficient in places, economists may be guilty of causing similar damage.  Hubris led economists to believe that booms and busts could be eliminated but their faith was shown to be spectacularly misplaced.  Despite this, economists have been slow to adjust their view of the world even though their remedies are proving both ineffective and costly.

The global financial crisis and its aftermath have taught us a few valuable lessons.  The limitations of using interest rates to moderate the business cycle (both before and after recessions) are now apparent.  Higher interest rates do little to temper lending when both bankers and borrowers want more debt.  It is also becoming clear that different sectors of the economy react to interest rates in different ways.  Consumers have shown themselves willing to take on excessive debt in order to spend or to buy property.  On the other hand, businesses cannot always be enticed to borrow for investment when the economy is weak. 

The limits of monetary policy have been laid bare by the faltering economic recovery.  Low interest rates and cheap cash have spurred on some lending but not the right type to generate sustainable economic growth.  Households have taken on debt to buy property (which mostly just increases prices) rather than businesses or the government borrowing to make the economy more productive.  Surplus funds have also built up prices in the stock market which, while somewhat beneficial in the short term, will create problems down the line.  The abundance of cash in the financial system may also reduce the effectiveness of central banks’ control over interest rates. 

For a better world

Monetary policy needs to continue to develop as economists learn more about the economy and how it reacts to different policies.  Manipulating interest rates is a blunt instrument that is applied across the whole economy.  Interest rates need to be raised eventually but it seems rash to do so in response to distortions in certain sectors.  An early interest rate hike has been proposed as a countermeasure to the booming UK property market.  Yet, this is like chopping off an arm to treat an infected finger.

A more measured approach would be preferable but will take time to realise.  Techniques such as minimally invasive surgery have been developed in medicine over many years and economists should aim for similar progress in monetary policy.  Disparities between policies in theory and practice mean that trial and error will be necessary.  Using a still sickly economy to trial new policy options may seem reckless.  Yet experimentation is the main route to breaking fresh ground even in medicine where there are actual lives at risk.  Forward guidance is an example of a policy which seemed useful in theory but whose application was fraught with issues.

A wider range of policies would help deal with problems now and in the future with greater effectiveness.  These two goals can be achieved by the Bank of England trialling the much-discussed macroprudential policies such as caps on mortgages and other limits on property lending.  Having a greater range of options allows for better tailoring of policy while targeted measures enable greater freedom in setting interest rates to reflect the overall economy.  Just as modern medicine has had to advance beyond leeches, future monetary policy will need to progress past what we currently have and such an evolution will only happen as a result of taking bold actions today.
