Linda Goldberg and Signe Krogstrup have a revised model of a paper entitled “Worldwide Capital Circulation Pressures and World Elements”. They write:
we revisit these points by recognizing that the noticed responses of portions of capital flows, trade charges, and home financial coverage to international components are interdependent and in lots of international locations can’t be studied in isolation. In international locations with absolutely versatile trade
price regimes, trade charges transfer rapidly in response to incipient modifications in capital flows, supplementing and even obviating the adjustment observable in capital circulate volumes (Chari, Stedman and Lundblad, 2021). In distinction, in mounted trade price regimes, managed floats, and even in some de jure versatile trade price regimes, central banks use coverage interventions equivalent to home rate of interest modifications and official overseas trade interventions to cut back the realized trade price response to international components (Ghosh, Ostry and Qureshi, 2018).1 In such circumstances, capital circulate pressures could present up in overseas trade interventions or in coverage price modifications reasonably than in trade charges. Accordingly, viewing capital circulate responses to international components individually from the trade price or coverage response will present an incomplete image of the particular capital circulate pressures at play.
To account for the interdependencies between capital flows on the one hand, and trade price modifications, overseas trade interventions and coverage price modifications on the opposite, we first current a brand new measure of worldwide capital circulate pressures, which is a revamped model of an Change Market Strain (EMP) index. EMP indices are weighted and scaled sums of trade price depreciation, official overseas trade intervention, and coverage price modifications. Earlier variations of trade market stress indices have been utilized in a broad vary of functions within the literature, from finding out stability of funds crises (Eichengreen, Rose and Wyplosz 1994) to financial coverage spillovers (Aizenman, Chinn and Ito 2016b) and classifying trade price regimes (Frankel 2019). Nevertheless, the weighting and scaling of the inputs have problematic options, main these indices to mischaracterize the patterns of pressures throughout international locations and over time, as mentioned extra extensively within the Appendix.
Our development as an alternative derives the related weighting and scaling phrases throughout the index via an strategy that makes use of key relationships in stability of funds equilibrium, worldwide portfolio calls for for overseas property, and valuation modifications on portfolio-related wealth.2 …”
The paper describes intimately the (concerned) calculation of their index. Determine 3 within the paper depicts the time collection for 4 international locations. I reproduce panel b and d (China and Switzerland, respectively) beneath.

One statement based mostly on their indices:
Throughout the highest stress episodes, international locations on common enable extra trade price variation to soak up capital circulate pressures than throughout regular instances and even throughout in any other case elevated threat sentiment. Some international locations may acknowledge that intervention within the overseas trade market is probably not as efficient during times of maximum stress when forex pressures are massive and may entail dropping massive portions of official overseas forex reserves, in order that they take no less than a short lived forex depreciation.
“Overseas trade intervention accounts for almost all of the EMP that’s not attributed to trade price actions. The rate of interest element accounts for nearly all variation for only a few international locations. The contribution of the rate of interest element is most pronounced in international locations with excessive inflation and coverage charges that haven’t been constrained by the efficient decrease sure and nil decrease sure. Central banks in these international locations have been in a position to make use of the coverage price extra actively in response to capital circulate pressures. …”
Some contrarian findings relating to secure haven currencies:
“…determinants related to secure property discovered little help within the knowledge, with the dimensions of the general public debt and gross overseas positions often and weakly displaying vital associations. Monetary market improvement and monetary openness modifications over time, with nation mounted results in specs, don’t differentiate threat habits of realized extra returns.”
