This 20th annual review of the international role of the euro published by the European Central Bank presents an overview of developments in the use of the euro by non-euro area residents.
      
    
    
      
 The report covers developments in 2020. This period was 
characterised by the outbreak of the coronavirus (COVID-19) pandemic, a 
contraction in global economic activity unprecedented in living memory 
and exceptional global policy support. On balance, however, these 
developments did not result in a significant change in the international
 role of the euro. In particular, the euro’s share in outstanding 
international loans, in the stock of international debt securities and 
as an invoicing currency for extra-euro area imports of goods remained 
broadly stable. The share of the euro in global foreign exchange 
reserves declined, as did the share of the euro in foreign 
currency-denominated debt issuance and in outstanding international 
deposits. The euro remained a key currency in international green bond 
markets, a small but rapidly growing segment of international debt 
security markets.
 The international role of the euro is primarily supported by a 
deeper and more complete Economic and Monetary Union, including 
advancing the capital markets union, in the context of the pursuit of 
sound economic policies in the euro area. The Eurosystem supports these 
policies and emphasises the need for further efforts to complete 
Economic and Monetary Union. The relative resilience of the 
international role of the euro despite the pandemic shock stands in 
contrast to the significant decline observed in the wake of the euro 
area sovereign debt crisis. To some extent, this development may reflect
 the effectiveness of the unprecedented policy support measures and 
coordinated approach that have prevailed in the euro area during the 
COVID-19 crisis. At the same time, the fact that the global appeal of 
the euro remains broadly stable at a low level suggests that only 
further resolute policy measures and reform efforts would enable the 
euro to realise its global potential.
 The ECB  will continue to monitor developments and publish information on the international role of the euro on a regular basis.

 1 Main findings
 The international role of the euro remained broadly stable in 2020. 
This period was characterised by the outbreak of the coronavirus 
(COVID-19) pandemic, a contraction in global economic activity 
unprecedented in living memory and exceptional global policy support. On
 balance, however, these developments did not result in a significant 
change in the international role of the euro.
 A composite index of the euro’s international role remained broadly stable over the review period at a low level (Chart 1).
 Adjusting for exchange rate valuation effects, the index declined 
slightly by 0.3 percentage points. At current exchange rates, it 
remained unchanged overall. The share of the euro across various 
indicators of international currency use was close to historical lows, 
averaging around 19%. The euro remained unchallenged as the second most 
important currency in the international monetary system (Chart 2).
 
 
 The share of the euro in global foreign exchange reserves decreased by 0.7 percentage points over the review period (Table 1).
 Survey evidence suggests that low or negative interest rates are a 
concern among official reserve managers globally. The low level of 
interest rates in the euro area compared with other major economies may 
therefore have discouraged official reserve investors from increasing 
the exposure of their bond portfolios to the euro. The share of the US 
dollar, the leading currency, in global foreign exchange reserves was 
stable over the review period. It remained close to a two-decade low, in
 line with previous trends towards gradual diversification of global 
reserve portfolios. Considering other structural factors, recent ECB  
staff research suggests that economies with a large share of the euro in
 official foreign exchange reserves typically have strong trade and 
financial linkages with the euro area and use the euro as an anchor 
currency (Box 1)....
