Summary of "Measures of Fiscal Risk in Hydrocarbon-Exporting Countries"

Core Content

This IMF Working Paper by Carlos Caceres and Leandro Medina analyzes fiscal risk in hydrocarbon-exporting countries, particularly in the Middle East and North Africa (MENA) region, due to oil price volatility. The paper introduces two measures of fiscal risk that assess the probability of oil prices falling below the break-even price, which is the level at which fiscal accounts are in balance given current spending levels.

Main Points

• Fiscal Improvements and Risks: High global oil prices have improved public finances in many hydrocarbon-exporting countries, but fiscal risks remain high due to increased spending packages and high volatility in oil prices.

• Break-Even Prices: Break-even prices are the oil price levels that balance the fiscal accounts for a given year. These prices have increased in many countries, and in some cases, are near or exceed current spot prices.

• Fiscal Vulnerability: Countries with large net assets and proven oil reserves are less vulnerable to fiscal risk than standard break-even price measures suggest.

• Volatility and Uncertainty: Oil price volatility is a key factor in fiscal risk, making it difficult to forecast and affecting the sustainability of fiscal policies.

• Empirical Methodology: The study uses a geometric Brownian motion model to simulate future oil price paths based on historical volatility and mean. Monte Carlo simulations are employed to estimate the probability of oil prices falling below break-even levels.

• Two Risk Measures:

  • Measure I: Assumes break-even prices remain constant in real terms from 2011 onwards.
  • Measure II: Uses break-even prices estimated by IMF country teams for the period 2012–2017, reflecting more realistic fiscal planning.

• Simulation Results:

  • In 2012, the probability of oil prices falling below break-even prices varies significantly across countries.
  • Countries like Kuwait, Qatar, and Saudi Arabia have low fiscal risk, while Yemen, Algeria, and Bahrain have high probabilities (over 40%).
  • Libya's break-even price drops significantly from 2011 to 2012 due to political stabilization.

• Limitations of Break-Even Prices:

  • They only consider a single year's fiscal balance and do not account for accumulated assets or liabilities.
  • They are exogenous to oil price changes, not endogenous, which limits their ability to fully capture fiscal risk over time.

Key Information

• Data Sources: Annual data from 1980 to 2011, with projections up to 2017.
• Model Used: Geometric Brownian motion to simulate oil price paths, taking into account historical volatility and mean.
• Countries Analyzed: 11 hydrocarbon-exporting countries in the MENA region (Algeria, Bahrain, Iran, Iraq, Kuwait, Libya, Oman, Qatar, Saudi Arabia, UAE, Yemen).
• Break-Even Price Trends:
  • Real break-even prices are presented in Table 2.
  • Nominal break-even prices are listed in Table 1.
• Fiscal Risk Probabilities:
  • Measure I results are shown in Table 3.
  • Measure II results are shown in Table 4.
• Implications: Countries with high break-even prices are more vulnerable to oil price shocks, and fiscal consolidation is necessary to build buffers and reduce exposure.

Figures and Tables

• Figure 1: Real break-even prices in selected MENA countries.
• Figure 2: Real Brent oil price (in 2011 U.S. dollars per barrel).
• Figure 3: Probability of Brent oil prices falling below break-even prices (measure I).
• Figure 4: Probability of Brent oil prices falling below break-even prices (measure II).
• Tables:
  • Table 1: Projected nominal break-even prices.
  • Table 2: Projected real break-even prices.
  • Table 3: Probability of oil prices falling below break-even prices (measure I).
  • Table 4: Probability of oil prices falling below break-even prices (measure II).

Conclusion

The paper concludes that some countries in the MENA region are more resilient to oil price fluctuations than others, and that fiscal consolidation is crucial for those more vulnerable. The two measures of fiscal risk provide a probabilistic assessment of oil price risks, helping policymakers prepare for potential fiscal challenges.
