Overall, in spite of the levelling off that occurred after the Great Financial Crisis and affected the euro area less than the rest of the world, most economies are currently much more integrated than they were in 2003 and the signs of an outright reversal of globalisation are limited. Such changes strongly affected the landscape in which monetary policy operates, as highlighted in a recent report conducted as part of the Monetary Policy Strategy Review of the ECB.
Increased synchronisation of economic and financial cycles across countries
Economic and financial variables across countries co-move more tightly in a world characterised by stronger trade and financial linkages. Such synchronisation is noticeable for real variables such as business cycles and for financial variables. Fluctuations in capital flows and the prices of risky assets respond to global factors which are common across countries. Importantly, inflation in the euro area became increasingly synchronised with that of other advanced economies, especially due to the co-movement of the most volatile portions of the CPI. Moreover, although globalisation has affected price and wage-setting, the analysis concluded it has had a second-order effect on trend inflation and on the flattening of the Phillips curve, when compared with factors such as de-anchoring of inflation expectations. One reason behind such - perhaps counterintuitive - result lies in that, whereas trade openness can intensify competition and thus exert downward pressure on inflation, it has also been associated to the emergence of superstar firms operating in oligopolistic contexts that tend to absorb cost fluctuations in their margins. Furthermore, although the share of goods originating from low-wage countries in euro area consumer expenditures doubled since the beginning of the 2000s, the overall contribution to consumer price index (CPI) inflation was rather modest because inflation in those countries increased at a similar pace than that of the euro area (even slightly faster) -see Balatti et al, (2021) for a detailed discussion of the inflation impact of globalisation).
Globalisation affects the environment in which monetary policy operates
The Strategy Review study on globalisation concluded that trade integration contributed to boosting productivity growth by improving the allocation of resources to more productive countries, sectors, and firms, and by providing incentives for technological innovation. It also shows that financial integration explains to some extent the fall in the natural rate of interest (the rate at which inflation is constant over the longer run, labelled r*) by increasing the supply of global savings and by boosting the global demand for safe assets. r* has been steadily declining over the past decades (Figure 3, Federal Reserve Bank of New York) (Marx, Mojon and Velde, 2017; Brand, Bielecki and Penalver, 2018). The report also documents that globalisation has been associated with greater wealth and income inequality within countries.
