In addition to setting interest rates, central banks also communicate with the public about economic conditions and future actions. While it has been established that communication can drive expectations, less is known about how it does so. This column attempts to shed light on this question. Applying novel measures to the content of Federal Reserve statements, it shows that forward guidance is a more important driver of market variables than disclosure of information about economic conditions.

Most lending by banks to corporations occurs through loans with floating interest rates. As a result, conventional monetary policy actions are transmitted directly to borrowers via a change in the interest rate paid on existing bank loans. This column argues that the ‘pass-through’ of policy rates to the cost of outstanding bank loans has significant real effects for corporations.

Interest rates have been extremely low since the Global Crisis. This column surveys the recent debate over whether they will remain low, or return to normal. While an unequivocal answer is not possible, the evidence suggests a significant decline in average real rates – perhaps to as low as 1%.

No-one is sure what the Fed’s long-delayed nominal interest rate hikes will bring, and there has been much speculation on what the equilibrium rate might look like when the Fed acts. This column argues that it would be foolish to attempt to pin down a precise value for the steady-state real rate. A better approach is to predict the plausible range of values, and evidence suggests that the equilibrium rate will range from a little above zero up to 2%.

Interest rates are near zero – or moving towards it – in major economies worldwide. This column introduces a new theoretical framework that helps to organise thinking on how liquidity traps and slow growth spread across the world. It stresses the role of capital flows, exchange rates, and the shortage of safe assets. Once rates are at the ZLB, the imbalance between the supply and demand of safe assets is redressed by lower global output. Liquidity traps emerge naturally and countries drag each other into them.

Discussions on the connection between the level of interest rates, incentives to search for yield, and financial stability have been prominent over the last ten years or so. More recently, Larry Summers argued in his 2014 secular stagnation address that the decline in the real interest rates would be expected to increase financial instability. This column addresses the challenging issue of providing an explanation for the connection between these phenomena. An increase in the supply of savings that reduces equilibrium real rates can be associated with an increase in the risk of the banking system. This link can explain the emergence of endogenous boom and bust cycles.

An important channel for monetary policy transmission is through mortgage markets. This column illustrates how the effects of an interest rate lift-off, from the zero lower bound, on homeowners depend on three factors: the prevalent mortgage type in the economy (fixed or adjustable rate), the speed of the lift-off, and the inflation rate during the lift-off. This channel of transmission suggests that if the purpose of the lift-off is to normalise nominal interest rates without derailing the recovery, the Federal Reserve Bank and the Bank of England should wait until the economies show convincing signs of inflation taking off. Furthermore, the lift-off should be gradual and in line with inflation.

Joining the Eurozone was once a near unquestionably good idea. Now, the costs of joining the monetary union are under close scrutiny. This column takes a slightly different tack, presenting an alternative perspective on how joining the euro has impacted productivity in southern Europe. It turns out that capital wasn’t allocated efficiently across firms after cheap borrowing at low interest rates, impacting total factor productivity.

Does monetary policy really face a zero lower bound or could policy rates be pushed materially below zero per cent? And would the benefits of reforms to achieve negative policy rates outweigh the costs? This column, which reports the views of the leading UK-based macroeconomists, suggests that there is no strong support for reforming the monetary system to allow policy rates to be set at negative levels.

Claims that ‘austerity has failed’ are popular, especially in the Anglo-Saxon world. This column argues that this narrative is factually wrong and ignores the reasons underlying the Greek crisis. The worst move for Greece would be to return to its old ways. Greece needs to realise that things could actually become much worse than they are now, particularly if membership in the Eurozone cannot be assured. Instead of looking back, Greece needs to continue building a functioning state and a functioning market economy.

The conventional ‘trilemma’ view is that countries that allow free capital flows can still pursue independent monetary policies as long as they allow flexible exchange rates. This column examines the pass-through of Federal Reserve interest rates to policy rates in Chile, Colombia, and Mexico. The author concludes that, to the extent that central banks take into account other central banks’ policies, there will be ‘policy contagion’ and that, even under flexible rates, monetary policy will not be fully independent.

Recent experience with the zero lower bound on nominal interest rates, and the use of high-denomination notes by criminals and tax evaders, have led to revived proposals to phase out cash. This column argues that abolishing cash may be neither necessary nor sufficient to overcome the zero lower bound problem, and would severely undermine privacy. Allowing the public to hold reserves at central banks could reduce the need for deposit insurance, although the transition to the new regime and the effects on credit supply must be carefully considered.

Expectations are critical for macroeconomics and financial markets. But the expectation-formation process is not well understood. This column discusses some empirical characteristics of forecast disagreement from professional forecasters in the US, and discusses the ‘information frictions’ that underlie the heterogeneity of expectations.

Eurozone inflation has been persistently declining for almost a year, and constantly undershooting forecasts. Building on existing research, this column explores the conjecture that low inflation in the Eurozone results from an excess demand for safe assets. If true, this conjecture would have definite policy implications. Getting out of such a ‘safety trap’ would necessitate fiscal or non-conventional monetary policies tailored to temporarily take risk away from private balance sheets.

The post-Crisis G7 economies have suffered weak business investment despite record low interest rates and the favourable financial positions of corporates. Some consider this the ‘new normal’ arising from secular, supply-side forces that have contributed to declining potential growth rates. This column argues that structural factors alone are not sufficient to explain the current weakness in investment rates. There is thus room for positive surprise if companies realise the pent-up investment demand.

The share of compensation to labour in gross value added has declined in recent decades for most countries and industries around the world. Recent work has also used the share of compensation to labour in net value added as a proxy for inequality. This column discusses that gross and net labour shares have declined together for most countries since 1975 – an outcome consistent with the worldwide decline in the relative price of investment goods.

Most of the world is now at the point where the support ratio is becoming adverse, and the growth of the global workforce is slowing. This column argues that these changes will have profound and negative effects on economic growth. This implies that negative real interest rates are not the new normal, but rather an extreme artefact of a series of trends, several of which are coming to an end. By 2025, real interest rates should have returned to their historical equilibrium value of around 2.5–3%.

Charles A.E. Goodhart, Philipp Erfurth, 03 November 2014

There has been a long-term downward trend in labour’s share of national income, depressing both demand and inflation, and thus prompting ever more expansionary monetary policies. This column argues that, while understandable in a short-term business cycle context, this has exacerbated longer-term trends, increasing inequality and financial distortions. Perhaps the most fundamental problem has been over-reliance on debt finance. The authors propose policies to raise the share of equity finance in housing markets; such reforms could be extended to other sectors of the economy.

The impact of the stock and maturity of government debt on longer-term bond yields matters for monetary policy. This column assesses the magnitude and relative importance of overall bond supply and maturity effects on longer-term US Treasury interest rates using data from 1976 to 2008. Both factors have a significant impact on both forwards and term premia, but maturity of public debt appears to matter more. The results have implications for exit from unconventional policies, and also for the links between monetary and fiscal policy and debt management.

Many central banks embrace forward guidance by announcing expected interest rate paths. But how likely it is that actual rates will be close to expected ones? This column argues that quantifying such uncertainty poses great difficulties. Precise probability statements in a world of uncertainty (not just risk) can be misleading. It might be better to rely on qualitative guidance such as: “Interest rate rises will probably be gradual and likely to be to a level below the old normal”.
