Understanding Global Imbalances

Against the backdrop of persistent and recently widening global imbalances, the paper presents a structured framework for understanding how domestic policies can influence current account positions by altering domestic saving and investment decisions. Staff analysis finds that traditional macroeconomic policies remain the dominant drivers of imbalances, but certain types of industrial policies could also play a role. Micro industrial policies—those targeting specific sectors or firms—generally have ambiguous and limited effects on the current account depending on their impact on aggregate productivity. Macro industrial policies—those deployed economy-wide and often paired with restrictions such as capital flow management measures—can materially affect the current account but come at a cost to consumption. Trade restrictions, often deployed to counter imbalances, would only meaningfully alter current account balances when used temporarily or to support higher public savings. Using scenario analysis, the paper shows how domestic rebalancing, undertaken simultaneously, across deficit and surplus economies yields both a reduction in global imbalances and higher global output. The report concludes that the future path of global imbalances will be largely shaped by domestic macroeconomic trajectories. Durable rebalancing is a collective endeavor: it requires sound domestic policy action across major economies and works best when countries move together. To help design such policies, the Fund is pursuing a multipronged approach by strengthening data, analysis, surveillance and dialogue across the member countries.
