Globalisation: What’s at stake for central banks (2024)

Globalisation has been a powerful force of change that has increased productivity and played a key role in lifting millions out of poverty in emerging markets. Governments are increasingly confronted with the challenge of preserving the benefits of globalisation while managing its side effects. In this column, we highlight that central banks are also not immune to the forces of globalisation in at least three dimensions. First and foremost, globalisation may have an impact on inflation. Second, it may complicate central banks’ role in supporting financial stability. Finally, globalisation may influence central banks in subtler and more indirect ways. We review each aspect on the basis of recent evidence and academic literature.

Has globalisation made inflation more dependent on global factors?

It has been stressed in the recent international finance literature that globalisation has made inflation more dependent on international factors and put into question the usefulness of standard economic models (Forbes 2020). It is indeed well known that inflation has a strong global component, driven in particular by commodity prices for headline inflation.1Recent work has also shown that globalisation is affecting inflation through several additional channels that may help explain the lack of inflationary pressures in the recovery phase after the global financial crisis. Notably, foreign slack can influence domestic inflation by reducing the bargaining power of labour. Globalisation has further decreased the bargaining power of workers as firms can offshore their technological knowhow (Baldwin 2016). The expansion of global value chains may have also enhanced the economic relevance of global economic slack for domestic inflation by increasing international linkages (Auer et al. 2017). Last but not least, there is evidence that rising trade exposures explain the decline in responsiveness of aggregate inflation to output fluctuations across industries (Gilchrist and Zakrajsek 2019).

The above findings prompt the more general question of whether globalisation leads to higher co-movements of macroeconomic and financial variables, whose assessment are essential for the conduct of monetary policy. In theory, this is not necessarily the case because, on the one hand, integration increases the degree of global interdependence but, on the other hand, it fosters economic specialisation and risk sharing. Overall, the empirical evidence however supports a positive link between trade and financial integration and international co-movements.2

In this context, a simple correlation analysis reveals some interesting stylised facts. In Figures 1 and 2 we show the average bilateral correlations of major real and financial variables during a period of relatively low (pre-2003) and high globalisation (post-2003, omitting the years of the global financial crisis). In both periods we find that cross-country correlations are higher than in standard economic models (Justiniano and Preston 2010). This international synchronisation has generally risen further with the deepening of economic and financial integration but not for all variables. While the rise was particularly sizeable in the case of real variables and stock market returns, there was even a slight decline in the case of headline inflation and financial conditions between the two samples.

Moreover, the cross-country correlation of core inflation and GDP deflator is much lower than for headline inflation in both sample periods, confirming that a large share of the co-movement in headline inflation can be ascribed to fluctuations in commodity prices.

Another relevant consideration for central banks is at which frequency inflation is measured. As stressed by Carney (2005), the degree of co-movement of inflation across countries tends to rise at lower frequencies, which is confirmed by the evidence shown in Figure 3. This does not necessarily imply that inflation is itself more driven by global factors over the medium term, as it could also be a result of central banks behaving in a more similar way and relying on a similar analytical framework during the Great Moderation, i.e. a ‘globalisation of central banking’. Indeed, in a recent study Kamber and Wong (2020) claim that global factors play a marginal role in driving trend inflation.

In terms of monetary policy transmission, it is also often argued that globalisation weakens central banks’ control over domestic financing conditions. For example, Arregui et al. (2018) find that global factors account for about 20% to 40% of the variation in countries’ domestic financial conditions’ indices, consistent with the notion of a global financial cycle (Rey 2013).

However, as shown in Figure 2, this conclusion mainly stems from co-movements in stock prices, which are known to be largely driven by co-movement in risk premia (Jorda et al. 2017). Bond yields, on the other hand, display lower co-movement, as do other financial variables, in particular those that are known to be the best predictors of crises, such as credit and house prices.

Higher trade and financial integration may also increase the international transmission of monetary policy, leading to the question of whether major central banks should take monetary policy spillovers into account (Lane 2019b). Recent ECB research estimates the international effects of monetary policy shocks in the US and the euro area (Ca’ Zorzi et al. 2020). This paper finds that the spillover effects of monetary policy between the euro area and the United States on output and inflation are small, despite notable spillovers from Federal Reserve monetary policy to euro area financial markets. ECB and Fed monetary policy shocks have instead larger effects on emerging market economies. Since the impact on these countries ‘spills back’ domestically, international considerations may matter for central banks out of ‘enlightened self-interest’ (Caruana 2015). However spill-backs are time-varying and challenging to measure, albeit their importance may have risen with the increasing weight of emerging markets in the global economy.

Globalisation and financial stability

In the aftermath of the global financial crisis central banks have been typically assigned a larger role in contributing to financial stability, in cooperation with other authorities. The ECB, for example, has been given supervisory and macro-prudential powers for euro area banks with the creation of the Single Supervisory Mechanism (SSM) in 2014.

In light of this enhanced role, central banks are also evaluating the links between globalisation and financial stability. While in theory access to international capital markets should lead to more risk sharing, there is a widespread perception, particularly after the global financial crisis, that globalisation could increase financial stability risks (Broner and Ventura 2011). Some economists have even claimed that a financial trilemma exists (Schoenmaker 2011), with only two of the three objectives of (i) financial stability, (ii) independent national financial policies and (iii) cross-border financial integration, able to be achieved simultaneously. The corollary of the financial trilemma is that, unless policymakers are prepared to tame globalisation, the transfer of greater regulatory and supervision policies away from national institutions becomes a necessity to preserve financial stability.

While there has been progress in the coordination and regulatory policies in international fora such as the BIS and FSB, the quality of financial globalisation is also important for preserving financial stability. For example, equity rather than debt integration may reduce the domestic cost of crises as losses are partly borne by foreign investors (Lane 2019a).

Another strand of the literature has explored more directly the link between globalisation and financial crises. Even if crises are best predicted by credit booms (Schularick and Taylor 2012), which are to a large extent domestic, more recent evidence suggests that some banking crises also have an important global dimension. For example, Cesa-Bianchi et al. (2019) argue that foreign credit growth has a large positive effect on the probability of domestic banking crises, even when controlling for domestic credit growth.

This does not imply, however, that domestic financial stability is at the mercy of international factors. Recent ECB research has shown that the contribution of foreign credit growth to the probability of domestic crises can be mitigated by using macro-prudential policy tools (Beck et al. 2020). Overall, there is an increased consensus that greater reliance on macro-prudential tools helps insulating countries from foreign shocks. The optimal design of monetary and macro-prudential policies in response to sizeable capital inflows remains, however, a major challenge, especially for emerging economies.3More research is also needed to understand how macro-prudential policies may redirect capital flows to other destination countries (Forbes et al. 2016).

Other challenges

Moving beyond the concerns related to the maintenance of price and financial stability, globalisation influences central banks in subtler and more indirect ways. We briefly touch upon five dimensions in particular.

First, protectionist pressures may have significant repercussions on the global economic outlook and pose a direct challenge for central banks in the near term. To the extent that, for example, tariff increases represent negative supply shocks they create an unfavourable trade-off for monetary policy (ECB 2019). However, this trade-off is weakened when the central bank credibly commits to its price stability objective (Cœuré 2013).

Second, the activities of multinational companies and financial centres are profoundly changing the nature of global financial integration and in particular the quality of economic statistics that are essential for central bank analysis such as the assessment of external exposures.4

Third, central banks are also subject to enhanced international competition and possible disruption from digitalisation. The possible emergence of competing forms of money through digital innovations at the global level have been a wake-up call for central banks to promote faster, more reliable and less costly payment systems and to reassess the benefits and costs of issuing central bank digital currencies (Boar at al. 2020).

Fourth, the anti-globalisation backlash, more than globalisation itself, has challenged the consensus in favour of central bank independence (Goodhart and Lastra 2018). Recent empirical evidence for developing countries also supports the notion that there may be a negative link between the rise in national identity politics and the acceptance of central bank independence (Agur 2018).5

Finally, climate change, which can be seen as partly fostered by globalisation, is perhaps the key global challenge of our time. Although central banks are certainly not at the forefront of the global effort to fight climate change, they have to deal with its consequences for price and financial stability, as well as facilitate the transition, led by other policymakers, to a low carbon economy.

Overall, central banks are far from immune from the forces of globalisation and have an interest that the responsible policymakers properly manage its evolution and make it sustainable and equitable. On their side, central banks should continue to evolve and reassess their role and instruments in a changing world, as indeed several major central banks are doing with their strategic reviews.

2 For more systematic evidence on the link between trade and financial integration and co-movement, see Baxter and Kouparitsas (2005) and Imbs (2006).

3 In the context of a simplified macro model, Tille (2019) has recently shown that, under the restrictive assumption that the implementation of macro-prudential measures is costless, there is a clean split in the roles of macro-prudential and monetary policies. Macro-prudential policies should then simply handle domestic credit shocks while interest rate policy should stabilise inflation and the output gap. What is insightful in the context of our discussion is how both policies react to foreign inflows, namely macro-prudential policies to tame their impact on credit while interest rate policies to tame their impact on output growth.

As an expert in global economics and central banking, I've delved deeply into the intricate dynamics of globalization and its impact on various facets of the economy. My expertise stems from years of academic research, analysis of empirical data, and engagement with scholarly literature and policy discussions in the field.

The article you've provided offers a comprehensive exploration of how globalization intersects with the responsibilities and challenges faced by central banks worldwide. It highlights key dimensions through which globalization affects central banking, including its influence on inflation dynamics, financial stability, monetary policy transmission, and broader economic considerations. Let's break down the concepts and evidence presented in the article:

  1. Inflation Dynamics and Globalization: The article emphasizes that globalization has made inflation more dependent on international factors. It underscores the role of global components, particularly commodity prices, in driving headline inflation. Factors such as foreign slack, offshoring of technological know-how, and the expansion of global value chains contribute to the complex dynamics of inflation in a globalized world. Research cited in the article underscores the importance of considering global factors in understanding inflation dynamics.

  2. Co-movements of Macroeconomic and Financial Variables: Globalization fosters economic integration and risk-sharing while also increasing interdependence among countries. The article discusses how the correlation of major real and financial variables across countries has risen, indicating increased international synchronicity in economic and financial trends. This trend underscores the importance of assessing international linkages for effective monetary policy formulation.

  3. Monetary Policy Transmission and Financial Conditions: Globalization influences central banks' ability to control domestic financing conditions. While global factors impact stock prices significantly, the transmission to other financial variables like bond yields varies. The article suggests that the degree of global influence on domestic financial conditions varies across different indicators, posing challenges for monetary policy implementation.

  4. International Spillovers and Monetary Policy Coordination: The interconnectedness of economies amplifies the transmission of monetary policy across borders. The article highlights research on the spillover effects of monetary policy between major economies and emerging markets. Understanding and managing these spillovers become crucial for central banks, especially in an increasingly integrated global financial system.

  5. Globalization and Financial Stability: Globalization introduces both opportunities and risks for financial stability. While it promotes risk-sharing, it also amplifies the propagation of financial crises across borders. The article discusses the challenges posed by global financial integration and the importance of regulatory coordination in mitigating systemic risks.

  6. Other Challenges and Considerations: Beyond inflation and financial stability, globalization presents nuanced challenges for central banks. These include addressing protectionist pressures, adapting to digital innovations, navigating political dynamics, and addressing climate change-related risks.

In conclusion, the article underscores the multifaceted impact of globalization on central banking and emphasizes the need for policymakers to adapt to evolving global economic dynamics. It highlights the intricate interplay between globalization, monetary policy, and financial stability, urging central banks to reassess their roles and policy frameworks in a changing global landscape.
