On 8 February, the Bank of England issued a statement that was seen by many as a warning for earlier and speedier than previously anticipated increases in the UK base rate. Mark Carney, the governor of the Bank of England, referred in his statement to ‘recent forecasts’ which make it more likely that ‘monetary policy would need to be tightened somewhat earlier and by a somewhat greater extent over the forecast period than anticipated at the time of the November report’.

A similar picture emerges on the other side of the Atlantic. With labour markets continuing to deliver spectacularly high rates of employment (the highest in the last 17 years), there are also now signs that wages are on an upward trajectory. According to a recent report from the US Bureau of Labor Statistics, US wage growth has been stronger than expected, with average hourly earnings rising by 2.9 percent – the strongest growth since 2009.

These statements have coincided with a week of sharp corrections and turbulence in the world’s largest capital markets, as investors become increasingly conscious of the threat of rising inflation – and the possibility of tighter monetary policy.

The Dow Jones plunged from an all-time high of 26,186 points on 1 February to 23,860 a week later – losing more than 10 per cent of its value in just five trading sessions (suffering a 4.62 percentag fall on 5 February alone – the worst one-day point fall since 2011). European and Asian markets followed suit, with the FTSE-100, DAX and NIKKEI all suffering heavy losses in excess of 5 per cent over the same period.

But why should higher inflationary expectations fuel a sell-off in global capital markets? After all, what firm wouldn’t like to sell its commodities at a higher price? Well, that’s not entirely true. Investors know that further increases in inflation are likely to be met by central banks hiking interest rates. This is because central banks are unlikely to be willing or able to allow inflation rates to rise much above their target levels.

The Bank of England, for instance, sets itself an inflation target of 2%. The actual ongoing rate of inflation reported in the latest quarterly Inflation Report is 3% (50 per cent higher than the target rate).

Any increase in interest rates is likely to have a direct impact on both the demand and the supply side of the economy.

Consumers (the demand side) would see their cost of borrowing increase. This could put pressure on households that have accumulated large amounts of debt since the beginning of the recession and could result in lower consumer spending.

Firms (the supply side) are just as likely to suffer higher borrowing costs, but also higher operational costs due to rising wages – both of which could put pressure on profit margins.

It now seems more likely that we are coming towards the end of the post-2008 era – a period that saw the cost of money being driven down to unprecedentedly low rates as the world’s largest economies dealt with the aftermath of the Great Recession.

For some, this is not all bad news – as it takes us a step closer towards a more historically ‘normal’ equilibrium. It remains to be seen how smooth such a transition will be and to what extent the high-leveraged world economy will manage to keep its current pace, despite the increasingly hawkish stance in monetary policy by the world’s biggest central banks.

  1. Using supply and demand diagrams, explain the likely effect of an increase in interest rates to equilibrium prices and output. Is it good news for investors and how do you expect them to react to such hikes? What other factors are likely to influence the direction of the effect?
  2. Do you believe that the current ultra-low interest rates could stay with us for much longer? Explain your reasoning.
  3. What is likely to happen to the exchange rate of the pound against the US dollar, if the Bank of England increases interest rates first?
  4. Why do stock markets often ‘overshoot’ in responding to expected changes in interest rates or other economic variables

On 2 November, the Bank of England raised Bank rate from 0.25% to 0.5% – the first rise since July 2007. But was now the right time to raise interest rates? Seven of the nine-person Monetary Policy Committee voted to do so; two voted to keep Bank Rate at 0.25%.

Raising the rate, on first sight, may seem a surprising decision as growth remains sluggish. Indeed, the two MPC members who voted against the rise argued that wage growth was too weak to justify the rise. Also, inflation is likely to fall as the effects of the Brexit-vote-induced depreciation of sterling on prices feeds through the economy. In other words, prices are likely to settle at the new higher levels but will not carry on rising – at least not at the same rate.

So why did the other seven members vote to raise Bank Rate. There are three main arguments:

Inflation, at 3%, is above the target of 2% and is likely to stay above the target if interest rates are not raised.
There is little spare capacity in the economy, with low unemployment. There is no shortage of aggregate demand relative to output.
With productivity growth being negligible and persistently below that before the financial crisis, aggregate demand, although growing slower than in the past, is growing excessively relative to the growth in aggregate supply.

As the Governor stated at the press conference:

In many respects, the decision today is straightforward: with inflation high, slack disappearing, and the economy growing at rates above its speed limit, inflation is unlikely to return to the 2% target without some increase in interest rates.

But, of course, the MPC’s forecasts may turn out to be incorrect. Many things are hard to predict. These include: the outcomes of the Brexit negotiations; consumer and business confidence and their effects on consumption and investment; levels of growth in other countries and their effects on UK exports; and the effects of the higher interest rates on saving and borrowing and hence on aggregate demand.

The Bank of England is well aware of these uncertainties. Although it plans two more rises in the coming months and then Bank Rate remaining at 1% for some time, this is based on its current assessment of the outlook for the economy. If circumstances change, the Bank will adjust the timing and total amount of future interest rate changes.

There are, however, dangers in the rise in interest rates. Household debt is at very high levels and, although the cost of servicing these debts is relatively low, even a rise in interest rates of just 0.25 percentage points can represent a large percentage increase. For example, a rise in a typical variable mortgage interest rate from 4.25% to 4.5% represents a 5.9% increase. Any resulting decline in consumer spending could dent business confidence and reduce investment.

Nevertheless, the Bank estimates that the effect of higher mortgage rates is likely to be small, given that some 60% of mortgages are at fixed rates. However, people need to refinance such rates every two or three years and may also worry about the rises to come promised by the Bank.

  1. Why did the majority of MPC members feel that now was the right time to raise interest rates whereas a month ago was the wrong time?
  2. Why did the exchange rate fall when the announcement was made?
  3. How does a monetary policy of targeting the rate of inflation affect the balance between aggregate demand and aggregate supply?
  4. Can monetary policy affect potential output, or only actual output?
  5. If recent forecasts have downgraded productivity growth and hence long-term economic growth, does this support the argument for raising interest rates or does it suggest that monetary policy should be more expansionary?
  6. Why does the MPC effectively target inflation in the future (typically in 24 months’ time) rather than inflation today? Note that Mark Carney at the press conference said, “… it isn’t so much where inflation is now, but where it’s going that concerns us.”
  7. To what extent can the Bank of England’s monetary policy be described as ‘discretionary’?

With first Houston, then several Caribbean islands and Florida suffering dreadful flooding and destruction from Hurricanes Harvey and Irma, many are questioning whether more should be spent on flood prevention and reducing greenhouse gas emissions. Economists would normally argue that such questions are answered by conducting a cost–benefit analysis.

However, even if the size of the costs and benefits of such policies could be measured, this would not be enough to give the answer. Whether such spending is justified would depend on the social rate of discount. But what the rate should be in cost-benefit analyses is a highly contested issue, especially when the benefits occur a long time in the future.

I you ask the question today, ‘should more have been spent on flood prevention in Houston and Miami?’, the answer would almost certainly be yes, even if the decision had to have been taken many years ago, given the time it takes to plan and construct such defences. But if you asked people, say, 15 years ago whether such expenditure should be undertaken, many would have said no, given that the protection would be provided quite a long time in the future. Also many people back then would doubt that the defences would be necessary and many would not be planning to live there indefinitely.

This is the familiar problem of people valuing costs and benefits in the future less than costs and benefits occurring today. To account for this, costs and benefits in the future are discounted by an annual rate to reduce them to a present value.

But with costs and benefits occurring a long time in the future, especially from measures to reduce carbon emissions, the present value is very sensitive to the rate of discount chosen. But choosing the rate of discount is fraught with difficulties.

Some argue that a social rate of discount should be similar to long-term market rates. But market rates reflect only the current generation’s private preferences. They do not reflect the costs and benefits to future generations. A social rate of discount that did take their interests into account would be much lower and could even be argued to be zero – or negative with a growing population.

Against this, however, has to be set the possibility that future generations will be richer than the current one and will therefore value a dollar (or any other currency) less than today’s generation.

However, it is also likely, if the trend of recent decades is to continue, that economic growth will be largely confined to the rich and that the poor will be little better off, if at all. And it is the poor who often suffer the most from natural disasters. Just look, for example, at the much higher personal devastation suffered from hurricane Irma by the poor on many Caribbean islands compared with those in comparatively wealthy Florida.

A low or zero discount rate would make many environmental projects socially profitable, even though they would not be with a higher rate. The choice of rate is thus crucial to the welfare of future generations who are likely to bear the brunt of climate change.

But just how should the social rate of discount be chosen? The following two articles explore the issue.

On the 15th June, the Bank of England’s Monetary Policy Committee decided to keep Bank Rate on hold at its record low of 0.25%. This was not a surprise – it was what commentators had expected. What was surprising, however, was the split in the MPC. Three of its current eight members voted to raise the rate.

At first sight, raising the rate might seem the obvious thing to do. CPI inflation is currently 2.9% – up from 2.7% in April and well above the target of 2% – and is forecast to go higher later this year. According to the Bank of England’s own forecasts, even at the 24-month horizon inflation is still likely to be a little above the 2% target.

Those who voted for an increase of 0.25 percentage points to 0.5% saw it as modest, signalling only a very gradual return to more ‘normal’ interest rates. However, the five who voted to keep the rate at 0.25% felt that it could dampen demand too much.

The key argument is that inflation is not of the demand-pull variety. Aggregate demand is subdued. Real wages are falling and hence consumer demand is likely to fall too. Thus many firms are cautious about investing, especially given the considerable uncertainties surrounding the nature of Brexit. The prime cause of the rise in inflation is the fall in sterling since the Brexit vote and the effect of higher import costs feeding through into retail prices. In other words, the inflation is of the cost-push variety. In such cirsumstances dampening demand further by raising interest rates would be seen by most economists as the wrong response. As the minutes of the MPC meeting state:

Attempting to offset fully the effect of weaker sterling on inflation would be achievable only at the cost of higher unemployment and, in all likelihood, even weaker income growth. For this reason, the MPC’s remit specifies that, in such exceptional circumstances, the Committee must balance any trade-off between the speed at which it intends to return inflation sustainably to the target and the support that monetary policy provides to jobs and activity.

The MPC recognises that the outlook is uncertain. It states that it stands ready to respond to circumstances as they change. If demand proves to be more resilient that it currently expects, it will raise Bank Rate. If not, it is likely to keep it on hold to continue providing a modest stimulus to the economy. However, it is unlikely to engage in further quantitative easing unless the economic outlook deteriorates markedly.

The US Federal Reserve, like many other central banks, engaged in massive quantitative easing in the wake of the financial crisis of 2007/8. Over three rounds, QE1, QE2 and QE3, it accumulated $4.5 trillion of assets – mainly government bonds and mortgage-backed securities (see chart below: click here for a PowerPoint). But, unlike its counterparts in the UK, the eurozone and Japan, it has long ceased its programme of asset purchases.. In October 2014, it announced that QE was at an end. All that would be done in future would be to replace existing holdings of assets as they matured, keeping total holdings roughly constant.

But now this policy is set to change. The Fed is about to embark on a programme of ‘quantitative tightening’, already being dubbed ‘QT’. This involves the Fed reducing its holdings of assets, mainly government bonds and government-backed mortgage-related securities.

This, however, for the time being will not include selling its holding of bonds or mortgage-backed securities. Rather, it will simply mean not buying new assets to replace ones when they mature, or only replacing part of the them. This was discussed by the 75 participants at the joint meeting of the Federal Open Market Committee (FOMC) and Board of Governors on 14–15 March.

As the minutes put it: “Many participants emphasized that reducing the size of the balance sheet should be conducted in a passive and predictable manner.”

A more active form of QT would involve selling assets before maturity and thus reducing the size of the Fed’s balance sheet more rapidly. But either way, reducing assets would put downward pressure on the money supply and support the higher interest rates planned by the FOMC.

The question is whether there is enough liquidity elsewhere in the system and enough demand for credit, and willingness of the banking system to supply credit, to allow a sufficient growth in broad money – sufficient, that is, to support continued growth in the economy. The answer to that question depends on confidence. The Fed, not surprisingly, is keen not to damage confidence and hence prefers a gradualist approach to reducing its holdings of assets bought during the various rounds of quantitative easing.
