Central scenario 2024: increasing risks due to delays in climate policies
Compared to last year’s edition, we revised our 2024 central scenario to reflect evolutions around climate change, geopolitical tensions, and the potential long-term impact of AI on the global economy. Our 2024 central scenario accounts for a higher probability of delays in climate policies and reduced prospects of reaching a 1.5-2°C target by 2050.
These adjustments have important macro implications for the next decade, with overall some lower transition risks and higher physical risks, as costs are being spread over a longer time period:
- Central banks will have to reconcile monetary policy objectives, high debt levels, and the need for relatively low long-term yields to fund the transition.
- Inflation – Our short-term inflation forecasts remain above central banks targets but have been cut from last year because the costs of the energy transition are spread over a longer time period. Over the medium-to-long term, an increase in productivity driven by AI together with more general cost reductions will drag inflation down towards central banks’ targets.
- Growth – Conversely, Developed Markets (DM) 10-year growth levels are revised upwards because of delayed climate policies and some positive effects stemming from the adoption of AI. We assume this adoption will be gradual, given the need to assess the social and energy costs of AI. Moving towards 2050, higher physical risks from extreme weather events and the diminishing effects of AI should bring growth down.
- Emerging Markets’ (EM) annual growth will be 2.3% higher than DM on average over 2024-2033. This growth advantage will diminish over the two subsequent decades as the road to net zero appears more challenging for many EMs. However, we also see some EM countries, such as Chile and Indonesia, benefitting from the transition, namely the ones rich in critical minerals.
- A carbon tax would have a significant impact on growth and inflation, particularly affecting EM and low-income households. A fair transition is at the heart of the case for carbon taxation.
