The Currency Peg Break Strategy is a rare but high-impact trading approach designed to exploit the sudden collapse or removal of a fixed exchange rate regime. Currency pegs, often maintained by central banks, are used to stabilise a currency’s value against another—typically the US dollar or euro. When such a peg fails, the result is extreme volatility, rapid revaluation, and systemic market shock, creating powerful trading opportunities.

This strategy gained widespread attention after the Swiss National Bank (SNB) removed the EUR/CHF floor in January 2015, triggering a 30% intra-day collapse in the franc and a historical moment in FX markets.

What Is a Currency Peg?

A currency peg is when a country’s central bank commits to keeping its exchange rate fixed or within a narrow band relative to another currency. Pegs are maintained through:

• Direct market intervention (buying/selling reserves)
• Capital controls
• Monetary policy alignment

Common examples:

• HKD/USD (Hong Kong Dollar to US Dollar)
• SAR/USD (Saudi Riyal to US Dollar)
• DKK/EUR (Danish Krone to Euro)
• Historical: CHF/EUR (Swiss Franc to Euro)

Strategy Objective

• Monitor and anticipate when a currency peg is under pressure
• Position for or react to the potential break or abandonment
• Exploit the massive one-sided moves that typically follow

Step-by-Step Currency Peg Break Strategy

Step 1: Identify Vulnerable Pegs

Look for pegs under stress due to:

• Diverging monetary policies (e.g. Fed hiking, pegged country cutting)
• Falling FX reserves (check central bank data)
• Increased speculative pressure (rising forward rates, widening spreads)
• Geopolitical or economic instability

Monitor news, IMF reports, and central bank signals for unsustainability warnings.

Step 2: Monitor Early Warning Signs

Key indicators:

• Rising volatility in forwards or NDFs (non-deliverable forwards)
• CB reserves depleting rapidly
• Sustained one-sided intervention
• Widening difference between spot and synthetic cross-rates

These are signs that the market may not believe the peg is credible.

Step 3: Pre-Break Positioning (Optional and Risky)

If confident in the break risk:

• Consider buying options (calls or puts) on the pegged pair
• Use low-delta OTM options to benefit from tail events
• Do not use high leverage on spot—peg defences can persist longer than expected

Alternatively, remain flat and prepare for post-break reaction trading.

Step 4: Immediate Reaction Strategy

Once the peg breaks:

• Expect massive gap moves, quote freezes, and liquidity collapse
• Wait for the first pause or consolidation after the panic
• Trade the secondary impulse or mean-reversion rebound

Example:

• After the SNB removed the EUR/CHF floor, price dropped from 1.2000 to 0.8500
• Rebounded to 1.0200+ within 24 hours
• Best trades occurred after initial chaos, not during

Step 5: Macro Repricing Phase

• Analyse new monetary policy expectations
• Watch central bank commentary post-break
• Trade the new trend using higher timeframes (H4, D1)
• Peg breaks often initiate multi-month directional moves

Example: SNB EUR/CHF Peg Break (2015)

• SNB had maintained 1.2000 floor since 2011
• In early 2015, ECB announced large-scale QE → pressure on SNB
• Jan 15, SNB unexpectedly removed the floor
• EUR/CHF collapsed nearly 30% in minutes
• Rebounded, then trended in 1.02–1.10 range for months

Instruments and Timeframes

• Currency Pairs: Pegged pairs like HKD/USD, SAR/USD, DKK/EUR
• Options: Long OTM options to play event risk
• Timeframes:
  • M1/M5 for reaction phase
  • H4/D1 for macro trend realignment

Advantages

• Huge asymmetric return potential
• No competition from traditional TA traders
• Trades driven by policy and macro dislocations
• Clear before-and-after regime shift

Limitations

• Rare—peg breaks happen infrequently
• Unpredictable timing
• Market can stay irrational longer than expected
• Execution risk during the break is high

Risk Management Tips

• Do not overleverage
• Trade post-break with confirmation rather than anticipation
• Avoid overnight exposure in pegged pairs when risk is high
• Use only defined-risk trades, like options or spreads

Conclusion

The Currency Peg Break Strategy offers one of the most explosive setups in global FX trading. By understanding the political, economic, and monetary forces behind pegs—and recognising when they are no longer sustainable—traders can prepare for rare but highly profitable opportunities.
