U.S. Monetary Policy Spillovers to Middle East and Central Asia: Shocks, Fundamentals, and Propagations

Overview

This IMF working paper analyzes the spillovers of U.S. monetary policy tightening on the Middle East and Central Asia (ME & CA) region, decomposing U.S. interest rate changes into pure monetary policy shocks (unexpected shifts) and information news shocks (containing Fed information effects). The study uses 16 ME & CA countries, focusing on different shock types, country fundamentals, oil prices, and global risk appetite to assess the regional impact, particularly the 2022 tightening cycle.

Key Findings

1. Spillovers from Different Shocks:

   • Contractionary Monetary Policy Shocks: Lead to negative growth impacts with delayed effects (3 years significant). Countries with weaker fundamentals (low reserves, high debt) suffer larger negative spillovers.
   • Positive Information News Shocks: Have positive growth effects, statistically significant for oil exporters but large heterogeneity exists. Countries with weaker fundamentals may benefit more due to reduced risk aversion and lower uncertainty.

2. Role of Oil Prices and Global Risk Appetite:

   • Higher oil prices buffer the negative impacts on oil exporters for monetary policy shocks.
   • Global risk appetite acts as an amplifier for both shocks: low risk appetite worsens negative spillovers, while high risk appetite amplifies positive impacts.

3. Heterogeneity in Spillovers:

   • Oil Exporters vs. Importers: Exporters are less affected than importers.
   • Fundamentals: Countries with strong macroeconomic fundamentals withstand the expansion slightly better, while imported oil prices cushion oil exporters.

4. 2022 Tightening Impact:

   • Mon policy component was slightly negative, reducing expected tightening.
   • Information shocks dominated, driving negative growth spillovers.
   • Average negative spillovers were moderate but heterogeneous; oil importers with weak fundamentals faced large negative impacts.

Categories and Descriptions

1. Contractionary Monetary Policy Spillovers:

   • Reduce growth, with delayed effects post shock.
   • More severe impact on nations with low reserves and high debt.
   • Aggravated by low oil prices and low global risk appetite.

2. Positive Information News Spillovers:

   • Boost growth via higher consumption, investment, and exports.
   • Benefited more by nations with weaker fundamentals in some cases due to risk-taking channel.
   • Can be amplified by higher global risk appetite.

3. Reforms and Counterfactuals:

   • Tightening cycle had minimal average impact due to partial alignment with market expectations.
   • Depends on fundamentals, global conditions, and policy stance. Stronger fundamentals or higher oil prices could mitigate effects in ME & CA.

Conclusions

The paper concludes that U.S. monetary policy tightening affects the ME & CA region in complex ways depending on policy drivers (monetary stance vs. information effect), country-specific fundamentals, and global environment. The 2022 cycle saw heterogeneous effects with oil exporters holding an advantage and oil-importing nations, especially with weak fundamentals, experiencing the harshest impacts. Building resilient fiscal frameworks is crucial for buffering against external financial shocks.
