How effective were monetary policy measures in response to the corona crisis?
Kerstin Bernoth, Geraldine Dany-Knedlik

The European Central Bank (ECB) and the US Federal Reserve (Fed) initiated far-reaching monetary policy measures to counteract the economic consequences of the corona-crisis (Table 1). Although the ECB and the Fed took quite similar measures, the initial monetary policy situation in the Euro area and the United States were noticeable distinct, which might affect their effectiveness. 

As the transmission process takes some time, it is not yet possible to fully assess the effectiveness of monetary policy measures to stabilise prices and the economy as a whole. However, in Bernoth et al. (2020), we provide initial insights into whether and how these measures have affected the yields of government bonds with different maturities. The analysis is based on an event study approach.  We expect an effective monetary stimulus to lower market interest rates on loans, thereby supporting lending and overall demand.

  • 3rd of March: Cut of key interest rate by 50 basis points to 1.25 percent.
  • 12th of March: Extension of the existing asset purchase program by €120 billion and further liquidity provision through the expansion of long-term refinancing operations.
  • 15th of March: Continuation of bond purchases worth 700 billion dollars and reduction of the key interest rate by a further 100 basis points.
  • 18th of March: Announcement of the Pandemic Emergency Purchase Program (PEPP) totaling €750 billion.
  • 23rd of March: Announcement to continue with the purchase of assets for as long as necessary.
  • 25th of March: Scrapping the issuance limit, which limited the purchase of government bonds to one third of the debt of each member state.

Table 1: 3 important monetary policy decisions during the corona-crisis

The analysis has three key findings: 

  1. By relaunching its bond purchase program and announcing unlimited bond purchases the Fed succeeded in significantly lowering yields on US government (Figure 1, left-hand column).
  2. The announcement of the ECB's monetary policy stimuli had no significant impact on the aggregate yields of European government bonds (Figure 1, right-hand column).
  3. However, looking at bond yields in individual countries, we find that Italian interest rates have fallen significantly following the scrapping of the issue limit on bond purchases.

There are various explanations for why the ECB's measures had only a limited effect on interest rates, in contrast to those of the Fed. One reason could be the ECB's very narrow scope for further monetary policy stimulus. In contrast to the US, the Euro area was still in the low interest rate environment after the Great Recession. Another explanation is that market participants were initially disappointed with the ECB's actions. For example, the effect of the Pandemic Emergency Purchase Program was muted when it was announced, as the emission limit was still in force at that time and the buy-up limit for some countries had already been reached before the corona crisis began. Nevertheless, it can be assumed that the ECB’s provision of sufficient liquidity to the banking sector in the near future will help to cope with the second-round effects of the crisis, such as a large number of non-performing loans. 

In view of the already very expansive monetary policy, however, the central banks' room to maneuver is generally limited. This makes it all the more important that monetary policy steps are flanked by targeted fiscal policy measures that stabilize aggregate demand and supply. In the Euro area, solutions must be found quickly, especially for distressed crisis countries such as Italy and Spain. Instead of wasting valuable time with lengthy political debates and introducing Eurobonds/corona bonds as a European response to the economic consequences of the coronavirus pandemic, we should consider rapid financial support in the form of direct transfers, which is explicitly allowed under Article 103a of the Maastricht Treaty in the case of exceptional events beyond the countries’ control.
