Foreign Exchange Risk Management Framework

Treasury Operations Policy

Executive Summary

This framework establishes a systematic approach to foreign exchange risk management that prioritizes capital efficiency and regulatory compliance. The methodology recognizes that FX losses have amplified impact on capital adequacy ratios, requiring a capital-adjusted approach to hedging decisions rather than traditional notional-based risk assessment.

Core Principle: All FX exposures are evaluated based on their capital-adjusted impact, with hedging decisions driven by economic break-even analysis rather than directional market views.

1. Framework Principles

1.1 Primary Objective

Minimize FX-driven P&L volatility to protect capital adequacy while optimizing both the economic cost of risk management and actual cash flow impacts from FX exposures and hedging activities.

1.2 Capital-Adjusted Risk Philosophy

• No Directional Views: Treasury does not take speculative FX positions
• Dual Cost Framework: Optimize both economic (capital-adjusted) and actual cash flow impacts
• Cash Flow Certainty: Balance immediate hedge costs against uncertain future FX realizations
• Regulatory Protection: Maintain stable capital adequacy ratios above covenant requirements
• Liquidity Management: Consider timing and magnitude of actual cash FX impacts
• Independent Assessment: Each exposure evaluated on individual economic and cash flow merit

1.3 Key Assumptions

• Capital Return Rate: 25% based on RAROC (Risk-Adjusted Return on Capital) principles
• Capital Multiplier: Regulatory capital requirements create leveraged impact of P&L movements
• Market Efficiency: FX hedge costs reflect fair value for risk transfer

2. Decision Methodology

2.1 Capital-Adjusted Impact Calculation

Formula:

Capital-Adjusted Impact = FX Exposure × Capital Multiplier × Capital Return Rate

Where:

• Capital Multiplier = (1 ÷ Minimum CAR Requirement)
• Capital Return Rate = 25% (RAROC-based target return)
• Combined Multiplier = Capital Multiplier × (1 + Capital Return Rate)

2.2 Economic Break-Even Analysis

Step 1: Calculate Break-Even FX Movement

Break-Even = Hedge Cost ÷ (Exposure × Combined Multiplier)

Step 2: Calculate Tenor-Based Value at Risk (VaR)

95% VaR = 1.65 × [Annual Volatility × √(Tenor in Years)]

Step 3: Risk Assessment

• VaR > Break-Even: Hedge economically justified
• VaR < Break-Even: Consider accepting risk
• VaR ÷ Break-Even Ratio: Measure of economic certainty

Volatility Sources: Use market-implied volatility where available, otherwise historical volatility over relevant periods.

2.3 Decision Matrix

3. Value at Risk (VaR) Methodology

3.1 VaR Conceptual Framework

Definition: Value at Risk measures the maximum expected loss over a specific time period at a given confidence level under normal market conditions.

Application: VaR provides the statistical probability that adverse FX movements will exceed our break-even threshold, enabling objective risk assessment.

3.2 Mathematical Foundation

Core Formula:

VaR(tenor, confidence) = Spot Rate × Volatility(tenor) × Confidence Factor

Tenor-Adjusted Volatility:

Volatility(tenor) = Annual Volatility × √(Tenor in Years)

Confidence Factors:

• 95% Confidence: 1.65 (5% probability of exceeding VaR)
• 99% Confidence: 2.33 (1% probability of exceeding VaR)
• Standard: Use 95% for routine decisions, 99% for material exposures

3.3 Tenor Scaling Examples

3.4 Volatility Data Sources

Primary Sources (in order of preference):

1. Market-Implied Volatility: From FX options (most forward-looking)
2. Historical Volatility: Rolling 252-day calculation (1-year business days)
3. Blended Approach: Weighted average of implied and historical

Calculation Method for Historical Volatility:

σ = √(252 × Σ(ln(St/St-1))²) / (n-1)

Where St = spot rate on day t, n = number of observations

Update Frequency: Monthly recalibration, or after significant market events

3.5 Practical Implementation

Step-by-Step Process:

1. Identify Exposure: Currency pair, notional amount, tenor
2. Source Volatility: Obtain annual volatility from preferred source
3. Scale for Tenor: Apply √time scaling formula
4. Calculate VaR: Apply confidence factor (typically 1.65)
5. Compare to Break-Even: Calculate VaR ÷ Break-Even ratio
6. Apply Decision Matrix: Execute per authority levels

Quality Controls:

• Volatility Range Check: Ensure volatility within reasonable bounds (5-30% annually)
• Historical Comparison: Validate against long-term averages
• Market Regime Recognition: Adjust for crisis periods or structural changes

3.6 Interpretation Guidelines

VaR ÷ Break-Even Ratio Meaning:

• 50x: 95% probability adverse movement is 50 times larger than hedge cost
• 10x: Strong statistical case for hedging
• 5x: Moderate case for hedging
• 2x: Marginal case, consider other factors
• <2x: Weak statistical case for hedging

Confidence Level Interpretation:

• 95% VaR: Expected to be exceeded 1 day in 20 (monthly occurrence)
• 99% VaR: Expected to be exceeded 1 day in 100 (quarterly occurrence)

4. Cash Flow Impact Assessment

4.1 Cash Flow Considerations

Hedge Cost Reality:

• Immediate: Hedge costs are paid upfront or over the hedge period
• Certain: Known cash outlay regardless of FX movements
• Budgetable: Can be planned and reserved for in cash flow projections

FX Exposure Reality:

• Future: FX gains/losses realized only upon settlement/conversion
• Uncertain: Direction and magnitude depend on future FX movements
• Variable: Impact timing may be controllable (e.g., conversion flexibility)

4.2 Cash Flow Decision Framework

Immediate vs Future Cash Impact:

Present Value of Expected FX Impact = VaR × Probability × Discount Factor

Cash Flow Timing Considerations:

• Hedge Cost: Immediate cash outlay
• FX Settlement: Future cash impact at conversion/settlement
• Financing Flexibility: Ability to time or defer FX conversions

4.3 Dual Assessment Approach

Economic Assessment (Capital-Adjusted):

• Use VaR ÷ Break-Even ratio for economic efficiency
• Consider regulatory capital impact
• Apply RAROC framework

Cash Flow Assessment:

• Liquidity Impact: Will hedge cost strain immediate cash position?
• Timing Mismatch: Can FX settlement timing be optimized?
• Refinancing Options: Are there alternatives to immediate hedging?

Combined Decision Rule:

• Both Assessments Positive: Hedge immediately
• Economic Positive, Cash Flow Negative: Evaluate timing alternatives
• Economic Negative, Cash Flow Positive: Consider partial hedging
• Both Assessments Negative: Monitor exposure

4.4 Cash Flow Optimization Strategies

When Hedge Cost is Material:

• Installment Hedging: Spread hedge cost over time
• Conditional Hedging: Use barrier options to reduce upfront cost
• Natural Hedging: Identify offsetting exposures within organization
• Timing Optimization: Leverage conversion flexibility where available

Documentation Requirements:

• Cash Flow Projection: Impact of hedge cost on liquidity
• Alternative Analysis: Evaluation of timing/structural alternatives
• Sensitivity Analysis: Range of potential FX cash impacts

8. Implementation Example: USD 500K THB Exposure

Background

Company receives USD 500K with THB funding requirement, creating FX exposure that impacts P&L under IFRS treatment of intercompany positions.

Capital Impact Calculation

• CAR Requirement: 15% minimum
• Capital Multiplier: 6.7x (1 ÷ 0.15)
• RAROC Return Rate: 25%
• Combined Multiplier: 6.7 × 1.25 = 8.375x

Economic Analysis

• FX Exposure: USD 500K
• Hedge Cost: THB 530K (USD 16.3K)
• Capital-Adjusted Exposure: USD 500K × 8.375 = USD 4.2M equivalent

Break-Even Calculation

• Break-Even: USD 16.3K ÷ (USD 500K × 8.375) = 0.39%

VaR Assessment

• Exposure Tenor: 1 year
• USD/THB Annual Volatility: 12% (market-based)
• 95% VaR: 1.65 × 12% = 19.8%
• VaR ÷ Break-Even Ratio: 19.8% ÷ 0.39% = 51x

Cash Flow Analysis

• Immediate Cost: THB 530K hedge cost (certain cash outlay)
• Potential FX Impact: USD 500K × 19.8% = USD 99K potential adverse movement
• Cash Flow Timing: Hedge cost immediate; FX impact at future settlement
• Liquidity Assessment: THB 530K manageable given refinancing flexibility

Combined Decision Assessment

• Economic Assessment: HEDGE IMMEDIATELY (VaR ratio 51x > 10x threshold)
• Cash Flow Assessment: POSITIVE (immediate cost acceptable, protects larger potential loss)
• Final Decision: HEDGE IMMEDIATELY

Implementation

Execute full FX forward hedge for USD 500K at THB 530K cost, eliminating both economic risk (USD 4.2M capital-adjusted exposure) and cash flow uncertainty (USD 99K potential adverse impact).
