Summary of Commodity Markets Outlook: Persistence of Commodity Shocks

Core Content

This document provides an overview of global commodity market developments and outlooks for the period up to 2021, with a focus on the persistence of commodity price shocks. It analyzes how different types of shocks—transitory and permanent—affect various commodity groups, including energy, agriculture, and metals, and highlights the implications for commodity-exporting economies.

Main Viewpoints

• Commodity Price Recovery Post-Pandemic:

  • Almost all commodity prices recovered in the third quarter of 2020 after significant declines due to the COVID-19 pandemic.
  • Crude oil prices doubled from their April low to an average of $40/bbl in September 2020, but remained 33% below pre-pandemic levels.
  • Metal prices rebounded sharply, reaching levels above pre-pandemic values due to a faster-than-expected recovery in China's industrial activity.
  • Agricultural prices rose by 6% in 2020Q3, with some commodities experiencing sharp increases due to production shortfalls and supply chain disruptions.

• Outlook for 2021:

  • Oil prices are expected to average $41/bbl in 2020 and rise to $44/bbl in 2021, reflecting a gradual recovery in demand and easing supply restrictions.
  • Metal prices are projected to see modest gains of about 2% in 2021.
  • Agricultural prices are expected to rise slightly in 2021 following a 3% increase in 2020.
  • The main risk to the price forecasts is the duration and severity of the pandemic, particularly the possibility of a second wave in the Northern Hemisphere winter and the speed of vaccine development and distribution.

• Impact of Pandemic on Commodity Markets:

  • The pandemic caused a significant and heterogeneous impact on different commodity groups.
  • Energy prices fell nearly 60% between January and April 2020, while metals and food prices declined by 15% and 10%, respectively.
  • The recovery in oil prices was driven by OPEC+ production cuts, but the impact of the demand shock may last longer.
  • Agricultural prices were more affected by long-term structural factors, while metals were more sensitive to short-term economic cycles.

Key Information

Commodity Groups and Their Trends

• Energy:

  • Prices fell sharply in 2020Q2 but rebounded in 2020Q3.
  • Expected to average $41/bbl in 2020 and rise to $44/bbl in 2021.
  • The main risk is a prolonged pandemic or renewed lockdowns affecting demand.

• Non-Energy:

  • Prices rose modestly in 2020Q3.
  • Projected to see a small increase in 2020 and a further rise in 2021.

• Agriculture:

  • Prices rose by 6% in 2020Q3, with divergence between grain prices and other agricultural commodities.
  • Concerns about food insecurity in EMDEs have increased due to restricted food flows and labor movements.

• Metals and Minerals:

  • Prices saw a significant rebound in 2020Q3 due to strong global economic recovery and continued Chinese stimulus.
  • Metal prices are expected to rise modestly in 2021.

• Precious Metals:

  • Prices rose sharply, driven by the depreciation of the U.S. dollar and lower interest rates.
  • Gold prices increased by 8% in 2020 and are projected to remain stable in 2021.

Shocks and Their Persistence

• Transitory Shocks:

  • These are short-lived and often related to economic cycles, trade tensions, weather events, or supply disruptions.
  • Examples include the 2009 financial crisis, 1997 East Asian crisis, and the 2019 Vale accident in Brazil.

• Permanent Shocks:

  • These are long-lasting and affect commodity prices over extended periods.
  • Examples include the shale technology shock and biotechnology advancements in the 1990s.
  • Agricultural commodity prices are more influenced by permanent shocks, which account for two-thirds of their variability.

Analysis of Shocks

• The document uses a novel frequency domain approach to decompose commodity price movements into transitory and permanent components.
• On average, permanent shocks account for 47% of price variability across all commodities.
• Medium-term cycles (8-20 years) account for 32% of price variability, while business cycles (2-8 years) account for 17%.
• Only 4% of price variability is attributed to shocks that unwind in less than two years.

Implications for Policy Makers

• Commodity-exporting economies must consider the nature of shocks (transitory or permanent) when designing policy responses.
• Short-lived shocks can be buffered by temporary macroeconomic stimulus, while long-term shocks require structural policies to facilitate smooth economic adjustments.
• EMDEs that rely on cyclical commodities may benefit from building fiscal buffers during booms to support economic activity during downturns.

Structure and Data

• The report includes detailed price indexes, forecasts, and supply-demand balances for major commodity groups.
• It features a variety of figures and tables that illustrate the impact of the pandemic and the role of different types of shocks on commodity prices.
• The cutoff date for data used in the report is October 16, 2020.
• The report is published twice a year, in April and October, and can be accessed at www.worldbank.org/commodities.

Conclusion

• The document underscores the importance of understanding the nature of commodity price shocks—whether they are transitory or permanent—for effective policy-making.
• The pandemic has shown that commodity markets are highly sensitive to global economic conditions and that the recovery may be uneven across different sectors.
• The report highlights the need for adaptive and forward-looking policies to manage the volatility and long-term trends in commodity prices.
