Summary of "Prospects for Real and Financial Imbalances and a Global Rebalancing"

Core Content

This article examines the historical build-up and subsequent reduction of global real and financial imbalances, their link to the 2008 financial crisis, and the implications for future global economic stability. It highlights the need for structural policy adjustments to ensure a durable and orderly rebalancing of global growth patterns, particularly in the context of the G20's post-crisis policy agenda.

Main Points

1. Global Imbalances as a Precursor to the Crisis

• Global real and financial imbalances were identified as a key risk factor for the global economy before the 2008 crisis.
• These imbalances were driven by unsustainable policies in both deficit and surplus economies.
• The euro area maintained a relatively stable external balance throughout the period.
• The buildup of imbalances was linked to policies inconsistent with long-term sustainability, including lack of medium-term orientation, insufficient self-discipline mechanisms, and financial globalization.

2. Cyclical Reduction in Imbalances

• The reduction in global imbalances during the crisis was largely cyclical and may reverse as the global economy recovers.
• The narrowing of imbalances was attributed to:
  • Lower oil and commodity prices.
  • Diminished negative wealth effects from the housing and equity markets.
  • A contraction in global trade.
• However, the resumption of global growth and trade is expected to lead to a mechanical rewidening of imbalances unless structural adjustments are made.

3. Structural Factors and Future Risks

• Structural factors, such as limited social safety nets in emerging Asia and export-driven growth models, are likely to persist and contribute to the re-emergence of imbalances.
• The financial crisis has reinforced the importance of building reserves for future stability, although this must be balanced with other uses such as fiscal stimulus.
• Emerging Asia's current account surplus has not fully corrected, and its export-oriented growth model is expected to continue.
• If global imbalances re-emerge without adequate rebalancing, risks to the global economy could increase, especially if advanced economies fail to reduce public deficits and emerging economies do not diversify their growth models.

Key Information

• Global Imbalances Timeline: Since the mid-1990s, global imbalances have gone through four distinct phases, marked by changes in savings and investment patterns, capital flows, and exchange rate dynamics.
• US Current Account Deficit: The US deficit peaked at 6% of GDP in 2006, and while it has narrowed to -2.6% in 2009, it is expected to stabilize at around -2.7% by 2014.
• China's Current Account Surplus: China's surplus declined from nearly 10% of GDP before the crisis to about 7.8% in 2009, but is projected to rise again to 8.4% by 2014.
• Oil Exporters: These countries experienced a significant reduction in current account surpluses during the crisis, but are expected to see a return to pre-crisis levels.
• G20 Rebalancing Agenda: Launched at the Pittsburgh Summit in 2009, the G20 Framework for strong, sustainable and balanced growth aims to ensure a durable reduction in global imbalances.
• Exchange Rate Adjustments: While exchange rates were initially seen as a key adjustment mechanism, empirical evidence suggests they may not be the primary driver of balance correction.
• Supply-Side Adjustments: The article emphasizes the importance of supply-side reforms to facilitate a more sustainable and balanced adjustment process, reducing reliance on demand-side and exchange rate mechanisms.

Conclusion

The article concludes that the main surplus and deficit economies must implement the commitments made at the Pittsburgh G20 Summit to rebalance global demand patterns and ensure a durable and orderly reduction in global imbalances. Without structural policy adjustments, the risks of re-emerging imbalances and their adverse effects on the global economy could persist, undermining long-term stability and growth.
