      Non-technical summary
      The estimation of real-economic damages due to climate change physical risks remains an important
      challenge in the face of global warming.

    • Many economic models make significant simplifications on
      the channels of transmission of climate physical risks across the globe, often giving the impression that
      the risks for the Euro Area will be relatively small.
    • In particular, the role of global supply chains in the
      transmission and potential amplification of climate related physical risks has received little attention.
    • This is relevant because climatologists predict that direct impacts from climate change-induced natural
      disasters will materialize mainly outside the Euro Area.
    • Understanding potential real economy losses would also contribute to better portray the risks which
      could spill over into the financial system.
    • Introduction
      Recent estimates of real-economic damages due to climate change physical risks do not appear
      incredibly worrying, not at least those for European countries.
    • The ECB climate stress test of 2022 also finds relatively little impact from physical risks.
    • Nordhaus? seminal 1991 paper was one of
      the first to estimate the effect of climate change on economic output (Nordhaus, 1991).
    • Second, our paper relates to the literature that has started to analyse the transmission of climate risks
      across borders.
    • In this strand, however, the focus remains mostly on transition risks (Devulder & Lisack,
      2020, Frankovic, 2022, Krivorotov, 2022).
    • Third, we connect to the literature on the study of the propagation of climate physical risks across
      borders, which remains underdeveloped.
    • To
      our knowledge this paper is the first to apply IO modelling with physical risks on a global scale.
    • However, the authors use a general equilibrium modelling approach and estimate
      how sectoral changes in productivity due to physical climate risks affect a global, multisectoral,
      intertemporal general equilibrium model.
    • This paper aims at making economic impact assessments of climate change more realistic by
      incorporating a key element of globalization.
    • More specifically, this paper is the first to analyse the
      transmission of GDP losses from climate change related physical risks through global country-sector
      input-output linkages.
    • ), this paper makes a first important step towards getting a more realistic
      picture of the risks arising from climate change.
    • The natural hazards
      influenced by climate change are many and include floods and inundations, droughts, heatwaves,
      windstorms, and wildfires.
    • Importantly, physical risks do not only have a direct impact on the economy, as cascading or amplifying
      effects are also possible through input-output linkages.
    • In general, the global economy is exposed to physical risks which generate GDP losses.
    • Specifically, SPGlobal GDP-at-risk data are used to quantify the potential
      direct impact of physical risks on GDP at the country level.
    • This is done to account
      for the fact that the realization of physical risks from climate change reduces both domestic final demand
      and production capacity (Feng and Li, 2021).

    • However, not analysing the amplification of climate risks through supply chains for
      lack of data could lead to a large underestimation of the risks posed by climate change for economic and
      financial stability.

      exposure to physical risks of direct trading partners is a limited indicator for the amplification of losses
      through global value chains.

We analyse the macroeconomic

Key Points: 
    • We analyse the macroeconomic
      effects of supply chain reorientation through localisation policies, using a global dynamic
      general equilibrium model.
    • While arguments about comparative advantage, the potential forgone benefits of international specialisation and industry- and product-specific disruptions are familiar, there is less
      analysis on the macroeconomic effects of supply chain changes resulting from localisation policies.
    • The large sensitivity of the global economy to the recent supply chain shocks suggests that
      the international trade reconfiguration implied by localisation policies could also have sizable
      impacts on key macroeconomic variables such as output, employment and inflation.
    • Thus, localisation focuses on the
      goods in our model most closely related to global supply chains.
    • Retaliation also attenuates any positive effects from
      reshoring on output and implies a reduction in the volume of overall international trade.
    • This finding calls for limiting the scope of reshoring, such as by focusing on vital goods that are
      most susceptible to supply chain disruptions.
    • Either that, or the economic costs are considered a worthwhile trade-off for an increase
      in security of supply, for example.
    • While arguments about comparative advantage, the potential forgone benefits of international specialisation and industry- and product-specific disruptions are familiar, there is less
      analysis on the macroeconomic effects of supply chain changes resulting from localisation policies.
    • Recent supply chain shocks have had large effects, with disruptions in 2021 estimated
      to have reduced euro area GDP by around two percent and doubled the rate of manufacturing producer inflation (Celasun et al., 2022).
    • To analyse this issue, we simulate a (partial) reshoring of production back to Europe in
      a global dynamic general equilibrium framework.
    • Thus,
      localisation focuses on the goods in our model most closely related to global supply chains.3 We
      model reshoring through a direct change to the export goods? production-function parameters.
    • Since reshoring
      effectively shortens the supply chain, the sum of markups along the chain falls.
    • This means that imports that are at the end of the supply chain (i.e.

    • This dynamic, along with factors such as natural disasters, climate-change
      induced volatility and terrorism mean that supply chain disruptions could be a new normal
      (Grossman et al., 2021).
    • Our work contributes to the literature providing dynamic general equilibrium analyses of
      protectionist policies, in particular those using global macroeconomic models to quantify trade

    • (2020) consider a rich input-output structure and demonstrate that closer integration amplifies
      the adverse effects of protectionist trade policies.
    • Several recent studies have also examined the economic effects of a global trade fragmentation.
    • First, we modify a dynamic general

      Supply chain reorientation

      Our analysis focuses on imported inputs used to produce goods for export, as the introduction
      of localisation policies is in response to recent disruptions to global supply chains.

    • Since reshoring
      effectively shortens the supply chain, the sum of markups along the chain falls.
    • Further to
      these effects, engagement with global firms provides an opportunity for knowledge spillovers to
