Latin America Strategy Summary: International Reserve Adequacy

Core Content

This document by Banco BNP Paribas Brasil S.A. evaluates the adequacy of international reserves in several Latin American countries using the IMF's Assessing Reserve Adequacy (ARA) framework, with an additional commodity price shock adjustment. The analysis is aimed at informing FX and IR strategies in the region.

Key Countries and Their Reserve Positions

Brazil

• Current Reserves: Exceed the optimal level under all metrics.
• ARA Framework: Reserves are above the 100–150% range.
• Commodity Adjustment: Still holds reserves in excess even after adjusting for commodity price shocks.
• Sterilization Cost: High sterilization costs make it unlikely that the Central Bank of Brazil (BCB) will pursue further reserve accumulation.
• Strategy Implication: BNP Paribas remains skeptical about future reserve accumulation and supports a long BRL in RV trade.

Mexico

• Current Reserves: Within the 100–150% range.
• ARA Framework: Reserves are adequate.
• Commodity Adjustment: Reserves remain within the 100–150% range even after adjusting for commodity price shocks.
• Strategy Implication: Mexico's reserve position is stable and sufficient for FX and IR strategies.

Colombia

• Current Reserves: Within the 100–150% range.
• ARA Framework: Reserves are adequate.
• Commodity Adjustment: Reserves remain within the 100–150% range.
• Strategy Implication: Colombia's reserve position is adequate and supports the current strategy.

Chile

• Current Reserves: Within the 100–150% range, but only when the Economic and Social Stabilization Fund (ESSF) is included.
• ARA Framework: Reserves are adequate.
• Commodity Adjustment: Without ESSF, Chile's reserves would fall below the minimum. However, with ESSF, it is in a comfortable position.
• Strategy Implication: Chile's buffer is strong, especially with the ESSF, making it a stable asset for FX strategies.

Argentina

• Current Reserves: Below the adequacy ratio.
• ARA Framework: Reserves fall below the minimum level.
• Commodity Adjustment: Reserve adequacy ratio would fall even further, suggesting the need for increased reserves.
• Strategy Implication: Argentina's reserves are insufficient, and the central bank is likely to take action to increase them. BNP Paribas recommends short USDARS 3-month NDF and long USDARS 1y1y NDF for FX exposure.

ARA Framework Overview

• The IMF ARA metric combines various risks such as current account shocks, external liabilities, and capital flight into a risk-weighted liability stock.
• The component weights vary based on the exchange rate regime:
  • Floating FX: 30% short-term debt, 5% exports, 5% M2, 15% other liabilities.
  • Fixed FX: 30% short-term debt, 10% exports, 10% M2, 20% other liabilities.
• The adequate coverage for international reserves is generally between 100–150% of the calculated risk-weighted liability stock.

Commodity Shock Adjustment

• Commodity-dependent economies may need higher buffers to account for terms-of-trade shocks.
• The buffer calculation involves:
  • Estimating the 68% probability range (one standard deviation) for future prices of key commodities (copper, iron ore, soybean).
  • Subtracting the current spot price from the lower band of the future price range.
  • Multiplying the result by the share of the commodity in exports.
• The commodity buffer is used to adjust the original ARA metric to reflect realistic reserve needs.

Summary Table

Main Findings and Views

• Mexico, Colombia, and Chile maintain adequate or comfortable international reserve positions.
• Brazil has excess reserves, but the high cost of sterilization suggests a lack of motivation for further accumulation.
• Argentina is below the adequacy ratio and needs to increase reserves, especially when considering commodity price shocks.
• The commodity shock adjustment highlights the importance of sovereign wealth funds (e.g., Chile's ESSF) and price hedges (e.g., Mexico's oil price hedge) in securing financial stability.
• The ARA framework is considered a more comprehensive approach than traditional metrics like three months of imports or short-term debt coverage, as it accounts for dynamic and complex crisis scenarios.

Strategy Implications

• Brazil: No immediate need for reserve accumulation, supporting a long BRL position.
• Mexico: Reserves are adequate, but the sterilization cost and FX swap stock may influence policy decisions.
• Colombia: Adequate reserves, consistent with the IMF methodology.
• Chile: Comfortable position with ESSF, suggesting a stable FX environment.
• Argentina: Reserves are below adequacy, and the central bank is likely to increase them. BNP Paribas recommends short USDARS 3-month NDF and long USDARS 1y1y NDF for FX exposure.
