Andrew Krieger remains one of the most celebrated and often mythologized figures in the history of foreign exchange trading. His defining moment came during the chaos surrounding the 1987 stock market crash, culminating in his execution of the legendary Andrew Krieger: Analyzing the Famous 1987 Black Monday Dollar Short Strategy. Working for Bankers Trust at the time, Krieger identified a critical liquidity gap in the currency market that allowed him to short the US Dollar (USD) against the New Zealand Dollar (NZD) on a scale so massive it was rumored to have exceeded the entire money supply of New Zealand. This pivotal trade cemented his status as a true FX legend, demonstrating an unparalleled combination of acute macroeconomic analysis, extreme risk tolerance, and genius-level understanding of market mechanics. For traders seeking to understand the limits of aggressive macro trading, examining Krieger’s methods offers indispensable lessons in crisis profiteering, a core theme explored in The Legends of FX: Analyzing the Strategies and Psychology of the Best Forex Traders in the World.
The Genesis of a Macro Bet: Pre-Black Monday Analysis
Krieger’s massive short position against the USD was not a reaction to the October 19th stock crash alone; it was the inevitable culmination of long-term global macro analysis. Leading up to Black Monday, the US economy suffered from the “Twin Deficits”—large budget and trade deficits—which fundamentally weakened the USD’s long-term outlook.
The core thesis supporting the dollar short included:
- Fundamental Overvaluation: Despite efforts like the Plaza Accord (1985) and the Louvre Accord (1987) to coordinate currency adjustments, many macro analysts, similar to George Soros’s Strategy: How He Broke the Bank of England Using Macroeconomic Analysis, believed the USD still needed a significant downward correction to balance global trade.
- Market Fragility: The rapid rise in US interest rates and the instability signaled by the equity market bubble created a highly volatile environment. When the crash hit, there was a rapid, albeit brief, flight to the USD as a cash equivalent, but Krieger anticipated the longer-term structural problems would quickly reassert themselves, leading to massive USD selling.
Krieger’s psychological edge, documented in discussions about The Mindset of a Million-Dollar Trader: Psychological Traits Shared by Forex Giants, was the ability to distinguish short-term panic from long-term structural shifts. While many traders froze, Krieger saw the crash as the catalyst needed to realize the long-term macro devaluation thesis.
The Anatomy of the 1987 Black Monday Dollar Short Strategy
What made Krieger’s trade historically significant was not just the direction (short USD), but the selection of the counterpart currency and the sheer scale of execution.
The Strategic Short Against the Kiwi (NZD/USD)
Krieger realized that to achieve the necessary scale and leverage required by his conviction, trading against major pairs like the JPY or DEM would be too competitive and potentially offer insufficient volatility for immediate, substantial profit. He targeted the New Zealand Dollar (NZD).
Why the NZD?
- Thin Liquidity: The NZD market was relatively thin compared to the major currencies. While normally a constraint, Krieger recognized that during extreme stress, a focused attack on a thinly traded currency could lead to massive price dislocation—a concept central to high-stakes FX trading.
- Correlation Disconnect: While the NZD was subject to US interest rate changes, its relative stability in the immediate aftermath of the crash provided a momentary low-risk base from which to launch the short against the USD.
Krieger reportedly shorted the USD against the NZD, accumulating a position size estimated between $600 million and $1 billion, effectively shorting the dollar with extreme force. The resulting pressure on the NZD caused the currency to plunge drastically, leading to what some called “Krieger’s manipulation” of the Kiwi.
Aggressive Position Sizing and Liquidity Exploitation
Krieger’s success hinged on The Art of Aggressive Position Sizing in Forex. Bankers Trust had granted him an unprecedented $700 million trading limit, a testament to their confidence in his abilities and the realization that in global macro crises, the biggest gains require the biggest bets.
Krieger’s method leveraged a critical market concept:
When an asset (the USD) is being sold off globally due to a crisis, the selling pressure is magnified when the trade is channeled through a narrow, low-liquidity market (NZD/USD). Krieger’s trade was so large that the Reserve Bank of New Zealand (RBNZ) reportedly called Bankers Trust to verify the trade, and ultimately had to intervene to stabilize the NZD, effectively becoming Krieger’s counterparty. This level of market dominance is rarely seen, especially by an individual trader.
Case Study and Examples: Mobilizing $1 Billion in Capital
The specific dynamics of the 1987 trade offer practical lessons in deploying capital during systemic stress.
Example 1: The Initial Short Entry
The trade was initiated shortly after the equities market plunged on October 19th. While initial reaction saw some dollar strength as liquidity dried up, Krieger used sophisticated models and fundamental macroeconomic signals (which traders today might use alongside 5 Technical Indicators That Define the Success of Elite Forex Traders) to confirm the short entry point for the USD. The goal was to initiate the short *before* the structural dollar selling began in earnest, aligning with the principles of Contrarian Trading and Market Timing.
Example 2: The Liquidity Squeeze and the RBNZ Response
Once Krieger built his massive short USD/long NZD position (by selling the USD), the sheer volume began to overwhelm the limited available liquidity in the NZD market. This aggressive position sizing led to a rapid and dramatic drop in the value of the USD against the NZD (NZD/USD exchange rate increased). The RBNZ’s subsequent intervention to purchase NZD and stabilize the rate confirmed the market dislocation and allowed Krieger to exit his position swiftly at highly favorable rates.
Result: Krieger’s position generated profits estimated at $300 million for Bankers Trust within a few hours, a figure often cited as the largest single trading profit in history at that time.
Actionable Insights for Modern FX Traders
While modern regulatory and technological landscapes make replicating Krieger’s exact circumstances impossible, the underlying strategic lessons remain vital:
- Identify and Exploit Liquidity Gaps: Even in highly liquid markets today, crisis events (such as flash crashes or unexpected geopolitical news) create temporary imbalances. Study cross-market relationships (e.g., between the VIX and specific currency pairs) to identify situations where position sizing can temporarily overwhelm supply/demand, similar to the techniques analyzed in Risk Management Secrets: How Top Forex Traders Use Position Sizing to Survive Market Crashes.
- Combine Macro with Micro Timing: Krieger had a long-term macro view (USD devaluation) but waited for the Black Monday micro-event to provide the perfect, leveraged entry point. This synthesis of fundamental conviction and precise timing is the hallmark of elite traders like Bill Lipschutz and Michael Marcus.
- Embrace Conviction and Scale (Within Limits): Krieger’s firm gave him the capital limit because he exhibited extreme conviction backed by rigorous analysis. Retail traders should scale conviction proportionally. If the macro thesis is overwhelming, the position size should be appropriately large, provided risk management protocols are strictly followed. Techniques for applying historic strategies are covered in Backtesting the Best: Replicating the Success of Famous Forex Strategies (A Step-by-Step Guide).
| Krieger Strategy Element | Modern Equivalent Focus | Why it Matters |
|---|---|---|
| Macro Devaluation Thesis (USD Short) | Long-term fundamental analysis (e.g., interest rate differentials, debt levels) | Provides the direction and conviction for large bets. |
| Targeting the NZD (Low Liquidity Pair) | Exploiting thin liquidity in emerging market crosses or crypto pairs (From Fiat to Crypto). | Allows position size to influence price disproportionately during stress. |
| Black Monday Crisis Trigger | Waiting for systemic event (geopolitical shock, central bank surprise) | Creates the volatility and panic needed for explosive profit generation. |
Conclusion: The Legacy of Liquidity Exploitation
Andrew Krieger’s monumental 1987 Black Monday Dollar Short Strategy serves as a powerful reminder that the biggest profits in FX often materialize not during stable market conditions, but during periods of systemic crisis where conviction and capital can temporarily dominate market mechanisms. His targeted short on the USD against the thinly traded NZD was a masterclass in liquidity exploitation, demonstrating how elite traders leverage structural weaknesses to generate staggering returns. Understanding this blend of macroeconomic foresight, psychological preparedness, and tactical market execution is essential for anyone aspiring to the levels achieved by the world’s most successful currency speculators.

FAQ About Andrew Krieger’s 1987 Dollar Short Strategy
What was the core macro reasoning behind Andrew Krieger’s 1987 dollar short?
Krieger’s core reasoning was based on the US ‘Twin Deficits’ (budget and trade deficits), which fundamentally signaled a long-term devaluation of the US Dollar. Black Monday served as the immediate catalyst, turning the slow structural pressure into an immediate, exploitable crisis event, confirming his conviction.
Why did Krieger choose to short the USD against the New Zealand Dollar (NZD)?
He chose the NZD because the market for the ‘Kiwi’ was relatively thin and illiquid. This allowed his exceptionally large trade size (up to $1 billion) to exert massive pressure, causing an exaggerated price move in the USD/NZD pair that yielded far greater, faster profits than if he had traded against a major currency like the German Mark or Japanese Yen.
How did the size of the trade affect the New Zealand currency market?
Krieger’s position was so large—rumored to be comparable to New Zealand’s entire money supply at the time—that it caused the NZD to experience severe price dislocation. The trade forced the Reserve Bank of New Zealand (RBNZ) to intervene in the market to stabilize the currency, effectively validating Krieger’s trade and serving as his exit counterparty.
How does Krieger’s strategy relate to the concept of aggressive position sizing seen in other FX legends?
Krieger exemplified aggressive position sizing, similar to Stanley Druckenmiller’s Macro Approach, by placing a huge bet when conviction was highest during a systemic crisis. This strategy is characteristic of macro traders who understand that maximizing returns during rare, high-certainty events requires deploying disproportionately large capital.
What practical lesson can modern retail traders draw from Krieger’s liquidity exploitation?
Modern traders should focus on identifying areas of temporary illiquidity, often found in less-traded cross-pairs or during unexpected news events. While they cannot move the market, understanding where supply and demand is thinnest (using volume and order book analysis) allows for better high-impact entries and exits, a key element discussed in Chart Patterns That Built Fortunes.
