Posts Tagged ‘real interest rates’

Down down deeper and down, or a new Status Quo?

If you asked virtually any banker or economist a few years ago whether negative (nominal) interest rates were possible, the answer would almost certainly be no.

Negative real interest rates have been common at many points in time – whenever the rate of inflation exceeds the nominal rate of interest. People’s debts and savings are eroded by inflation as the interest due or earned does not keep pace with rising prices.

But negative nominal rates? Surely this could never happen? It was generally believed that zero (or slightly above zero) nominal rates represented a floor – ‘a zero lower bound’.

The reasoning was that if there were negative nominal rates on borrowing, you would effectively be paid by the bank to borrow. In such a case, you might as well borrow as much as you can, as you would owe less later and could pocket the difference.

A similar argument was used with savings. If nominal rates were negative, savers might as well withdraw all their savings from bank accounts and hold them as cash (perhaps needing first to buy a safe!) Given, however, that this might be inconvenient and potentially costly, some people may be prepared to pay banks for looking after their savings.

Central bank interest rates have been hovering just above zero since the financial crisis of 2008. And now, some of the rates have turned negative (see chart above). The ECB has three official rates:

The interest rate on the main refinancing operations (MRO), which provide the bulk of liquidity to the banking system.
The rate on the deposit facility, which banks may use to make overnight deposits with the Eurosystem.
The rate on the marginal lending facility, which offers overnight credit to banks from the Eurosystem.

The first of these is the most important rate and remains above zero – just. Since September 2014, it has been 0.05%. This rate is equivalent to the Bank of England’s Bank Rate (currently still 0.5%) and the Fed’s Federal Funds Rate (currently still between 0% and 0.25%).

The third of the ECB’s rates is currently 0.3%, but the second – the rate on overnight deposits in the ECB by banks in the eurozone – is currently –0.2%. In other words, banks have to pay the ECB for making these overnight deposits (deposits that can be continuously rolled over). The idea has been to encourage banks to lend rather than simply keeping unused liquidity.

In Nordic countries, the experiment with negative rates has gone further. With plenty of slack in the Swedish economy, negative inflation and an appreciating krona, the Swedish central bank – the Riksbank – cut its rates below zero.

Many City analysts believe that the Riksbank will continue cutting, reducing its key interest rate to minus 0.5% by the end of the year [it is currently 0.35%]. Switzerland’s is already deeper still, at minus 0.75%, while Denmark and the eurozone have joined them as members of the negative zone.

But the nominal interest rate on holding cash is, by definition, zero. If deposit rates are pushed below zero, then will more and more people hold cash instead? The hope is that negative nominal interest rates on bank accounts will encourage people to spend. It might, however, merely encourage them to hoard cash.

The article below from The Telegraph looks at some of the implications of an era of negative rates. The demand for holding cash has been increasing in many countries and, along with it, the supply of banknotes, as the chart in the article shows. Here negative interest are less effective. In Nordic countries, however, the use of cash is virtually disappearing. Here negative interest rates are likely to be more effective in boosting aggregate demand.

Central banks – summary of current interest rates


  1. Distinguish between negative real and negative nominal interest rates.
  2. What is the opportunity cost of holding cash – the real or the nominal interest rate forgone by not holding it in a bank?
  3. Are there any dangers of central banks setting negative interest rates?
  4. Why may negative interest rates be more effective in Sweden than in the UK?
  5. ‘Andy Haldane, a member of the Monetary Policy Committee (MPC) … suggested that to achieve properly negative rates, the abolition of cash itself might be necessary.’ Why?
  6. Why does Switzerland have notes of SF1000 and the eurozone of €500? Should the UK have notes of £100 or even £500?
  7. Why do some banks charge zero interest rates on credit cards for a period of time to people who transfer their balances from another card? Is there any incentive for banks to cut interest rates on credit cards below zero?

The political dynamite of calm economic reflection

In a carefully argued article in the New Statesman, the UK Business Secretary, Vince Cable, considers the slow recovery in the economy and whether additional measures should be adopted. He sums up the current state of the economy as follows:

The British economy is still operating at levels around or below those before the 2008 financial crisis and roughly 15 per cent below an albeit unsustainable pre-crisis trend. There was next to no growth during 2012 and the prospect for 2013 is of very modest recovery.

Unsurprisingly there is vigorous debate as to what has gone wrong. And also what has gone right; unemployment has fallen as a result of a million (net) new jobs in the private sector and there is vigorous growth of new enterprises. Optimistic official growth forecasts and prophets of mass unemployment have both been confounded.

He argues that supply-side policies involving “a major and sustained commitment to skills, innovation and infrastructure investment” are essential if more rapid long-term growth is to be achieved. This is relatively uncontroversial.

But he also considers the claim that austerity has kept the economy from recovering and whether policies to tackle the negative output gap should be adopted, even if this means a short-term increase in government borrowing.

But crude Keynesian policies of expanding aggregate demand are both difficult to implement and may not take into account the particular circumstance of the current extended recession – or depression – in the UK and in many eurozone countries. World aggregate demand, however, is not deficient. In fact it is expanding quite rapidly, and with the sterling exchange rate index some 20% lower than before the financial crisis, this should give plenty of opportunity for UK exporters.

Yet expanding UK aggregate demand is proving difficult to achieve. Consumers, worried about falling real wages and large debts accumulated in the years of expansion, are reluctant to increase consumption and take on more debts, despite low interest rates. In the light of dampened consumer demand, firms are reluctant to invest. This makes monetary policy particularly ineffective, especially when banks have become more risk averse and wish to hold higher reserves, and indeed are under pressure to do so.

So what can be done? He argues that there is “some scope for more demand to boost output, particularly if the stimulus is targeted on supply bottlenecks such as infrastructure and skills.” In other words, he advocates policies that will simultaneously increase both aggregate demand and aggregate supply. Monetary policy, involving negative real interest rates and quantitative easing, has helped to prevent a larger fall in real aggregate demand and a deeper dive into recession, but the dampened demand for money and the desire by banks to build their reserves has meant a massive fall in the money multiplier. Perhaps monetary policy needs to be more aggressive still (see the blog post, Doves from above), but this may not be sufficient.

Which brings Dr Cable to the political dynamite! He advocates an increase in public investment on infrastructure (schools and colleges, hospitals, road and rail projects and housing, and considers whether this should be financed, not by switching government expenditure away from current spending, but by borrowing more.

Such a strategy does not undermine the central objective of reducing the structural deficit, and may assist it by reviving growth. It may complicate the secondary objective of reducing government debt relative to GDP because it entails more state borrowing; but in a weak economy, more public investment increases the numerator and the denominator.

He raises the question of whether the balance of risks has changed: away from the risk of increased short-term borrowing causing a collapse of confidence to the risk of lack of growth causing a deterioration in public finances and this causing a fall in confidence. As we saw in the blog post Moody Blues, the lack of growth has already caused one ratings agency (Moody’s) to downgrade the UK’s credit rating. The other two major agencies, Standard & Poor’s and Fitch may well follow suit.

The day after Dr Cable’s article was published, David Cameron gave a speech saying that the government would stick to its plan of deficit reduction. Not surprisingly commentators interpreted this as a split in the Coalition. Carefully argued economics from Dr Cable it might have been, but political analysts have seen it as a hand grenade, as you will see from some of the articles below.

  1. Why has monetary policy proved ineffective in achieving a rapid recovery from recession?
  2. Distinguish between discretionary fiscal policy and automatic fiscal stabilisers.
  3. Why has the existence of automatic fiscal stabilisers meant that the public-sector deficit has been difficult to bring down?
  4. In what ways has the balance of risks in using discretionary fiscal policy changed over the past three years?
  5. In what ways is the depression of the late 2000s/early 2010s (a) similar to and (b) different from the Great Depression of the early 1930s?
  6. In what ways is the structure of public-sector debt in the UK different from that in many countries in the eurozone? Why does this give the government more scope for expansionary fiscal policy?
  7. Why does the Office of Budget Responsibility’s estimates of the tax and government expenditure multipliers suggest that “if fiscal policy is to work in a Keynesian manner, it needs to be targeted carefully, concentrating on capital projects”?
  8. Why did Keynes argue that monetary policy is ineffective at the zero bound (to use Dr Cable’s terminology)? Are we currently at the zero bound? If so what can be done?
  9. Has fiscal tightening more than offset loose monetary policy?

Living beyond our means?

The UK and US governments face a conundrum. To achieve economic recovery, aggregate demand needs to expand. This means that one or more of consumption, government expenditure, exports and investment must rise. But the government is trying to reduce government expenditure in order to reduce the size of the public-sector deficit and debt; exports are being held back by the slow recovery, or even return to recession, in the eurozone and the USA; and investment is being dampened by business pessimism. This leaves consumer expenditure. For recovery, High Street spending needs to rise.

But herein lies the dilemma. For consumer spending to rise, people need to save less and/or borrow more. But UK and US saving rates are already much lower than in many other countries. You can see this by examining Table 23 in OECD Economic Outlook. Also, household debt is much higher in the UK and USA. This has been largely the result of the ready availability of credit through credit cards and other means. The government is keen to encourage people to save more and to reduce their reliance on debt – in other words, to start paying off their credit-card and other debt. That way, the government hopes, the economy will become ‘rebalanced’. But this rebalancing, in the short run at least, will dampen aggregate demand. And that will hardly help recovery!

In the following podcast, Sheldon Garon discusses his new book Beyond Our Means. He describes the decline of saving in the USA and UK and examines why other countries have had much higher saving rates.

‘He also seeks to explain why high interest rates didn’t encourage saving in the boom years and why current levels of relatively high inflation haven’t stopped savings rates shooting up again in Britain.’
