To limit global warming to 1.5C, it is crucial to decarbonise the entire world. But pressuring emerging economies to reach net-zero emissions too quickly could lead to an explosion of dollar-denominated debt and financial volatility across the developing world. Integrating these countries into the decarbonisation effort requires a more nuanced strategy.Over the past year, policymakers and scholars, some from developing countries, have proposed solutions to this conundrum. As global leaders gather for the annual meetings of the International Monetary Fund and the World Bank in Marrakesh on October 9-15, three proposals in particular merit serious debate.While emerging and developing economies have contributed little to the climate crisis, their carbon dioxide emissions are increasing rapidly. To achieve the economic growth their citizens expect, stay within their carbon budgets, and shift away from fossil fuels, these countries must make significant investments in green technologies, primarily financed through international capital flows.The UN Conference on Trade and Development’s 2023 World Investment Report projects that developing countries will require $1.7tn in annual investments to achieve a green transition. In 2022, they managed to secure only $544bn. Most of this financing is dollar-denominated, exacerbating the debt burdens of low-income countries already struggling to service their existing obligations following the Covid-19 pandemic and Russia’s war on Ukraine.Relying on other foreign-currency funding seems just as impractical, given that most of these countries’ revenues are in their local currencies.The three proposals currently being discussed complement one another. The most well-known, the Bridgetown Initiative 2.0, has brought local-currency financing to the forefront of the global policy debate.The original Bridgetown Initiative – championed by Barbadian Prime Minister Mia Amor Mottley and her climate adviser, economist Avinash Persaud – focused on the issuance of special drawing rights (SDRs, the IMF’s reserve asset). The updated proposal, however, urges the IMF and multilateral development banks (MDBs) to offer subsidised guarantees that account for mispriced currency risks, thereby reducing developing countries’ borrowing costs.The second proposal is to scale up and provide guarantees to the Amsterdam-based TCX, a risk-pooling mechanism designed to provide low-income countries with a cost-effective way to shield themselves from currency fluctuations.The third proposal encourages MDBs and bilateral development-finance institutions to consolidate their liquidity requirements through an "onshore” platform that operates with local currencies.Although these three proposals are tailored for different countries and economic contexts, with widely varying effects on the long-term evolution of local currencies and domestic capital markets, they could be scaled up. The Bridgetown Initiative, for example, focuses on large emitters within emerging and developing economies. This is crucial for keeping global temperatures below the 1.5C threshold and could also be applied to many developed countries.Similarly, though TCX primarily deals with smaller and more volatile currencies, the proposed onshore vehicle would be tailored for countries with sufficiently mature institutions. This group could be expanded to include larger and more developed economies, allowing for a wider array of hedging mechanisms.The Bridgetown Initiative assumes a premium for hedging foreign-exchange risk in emerging and developing economies. While the initiative’s proponents have released a detailed empirical analysis that points to the existence of such a premium, its impact remains to be seen. Nevertheless, the overarching argument that investing in green technologies in these countries is much costlier than in advanced economies is undeniably persuasive.The TCX strategy hinges on the lack of correlation between various currencies. Naturally, the more currencies TCX includes, the greater the pooling benefits. By contrast, the economic rationale for the onshore platform stems from the expected reduction in hedging costs when the intermediaries have access to local currencies. While the ability to expand this approach is still uncertain, there is potential for achieving economies of scale.To avert a financial meltdown, the international community must assist emerging and developing countries in managing massive capital inflows. All three proposals should be combined with renewed efforts to bolster local institutions and markets. The onshore mechanism, unlike the other two proposals, could advance this goal by operating in partnership with central banks and commercial lenders.The urgency and global salience of the climate crisis have created a unique opportunity to advance this agenda. Enhancing developing countries’ ability to mobilise domestic savings and stabilise currency fluctuations would yield benefits that extend far beyond the net-zero transition.Moreover, the proposed onshore mechanism, which would facilitate increased co-ordination among MDBs, aligns with the broader goal of streamlining the international financial system. At present, credit-rating agencies penalise MDBs for lacking access to the same liquidity backstops as commercial banks. But by co-ordinating their liquidity management, multilateral lenders could significantly increase their lending capacity.While the development of local currency and capital markets has been limited thus far, there is cause for hope. Recent shocks to the international system have affected emerging economies less severely than previous crises, indicating greater macroeconomic resilience.Rising debt levels have raised fresh concerns, however, especially in the countries that are most vulnerable to the effects of climate change. Enhancing these economies’ resilience is crucial not just for the stability of the global financial system but also for sustaining the momentum of the fight against climate change. - Project Syndicate
