How to Hedge FX Risk in The Chaos Tipping Point : Simulating Black Swans and Building Resilience

Not since Covid or the Great Recession have we seen such chaos across all markets. The dollar is falling off a cliff, the VIX is at multi-year highs, and US Treasuries are selling off as the dollar’s ‘safe haven’ status fades.
Why Traditional FX Models Fail in Crisis
The world is on edge:
 Tariffs, uncertainty and retaliation threaten a world wide recession. Bond and equity markets in the US are now positively correlated and falling together as foreign investors flee.
Eighty-year-old alliances and norms are frayed or gone. The Pax Americana seems over.
There are hot wars in Europe, Africa (4) and of course the Middle East.
There’s a warm war in the South China sea between China, Philippines, and Taiwan
The Fragile States Index map, which measures the vulnerability of countries to economic collapse or conflict, is not a pretty sight (see below).
Using Jump Diffusion to Simulate Market Dislocation
A "chaos tipping point" refers to the critical point in a complex system where a perturbation can lead to a collapse of markets or an irreversible shift to a new economic paradigm. We don’t lack perturbations! These situations can actually be fertile ground for innovation and seizing new opportunities. But in the meantime, firms and funds must preserve and even grow value in the turmoil.
"In the midst of chaos, there is also opportunity." - Sun Tzu, The Art of War.
The basic response should be clear. The strongest response to these threats is resilience and adaptability in your capital stack and supply chain. But for FX in particular, having a robust FX policy and operational hedging program in place is essential. You can’t hedge in arrears!
For those with hedging programs, knowing how well they work during chaotic times is essential. Simulation is a common technique for measuring this efficacy. However, ordinary Geometric Brownian Motion is insufficient – its assumptions of stationarity (constant mean, variance and covariance) will never reproduce the large and rapid discontinuities characteristic of a Black Swan event. Instead, it is advisable to use either a Stochastic Vol simulation model with high vol of vol, or best - use a jump diffusion simulation.
The Merton Jump Diffusion (MJD) model is one of the first beyond Black-Scholes model in the sense that it tries to capture the negative skewness and excess kurtosis of the log stock price density by a simple addition of a compound Poisson jump process. Introduction of this jump process adds three extra parameters λ, μ, and δ (to the original BS model) which give the user control over skewness and excess kurtosis of the distribution, as well as jump likelihood and jump deviation.
Visualizing Risk: Violin Charts and Strategy Margins
It’s evident that MJD can simulate Black Swans or other severe market dislocations. Using a distribution like this can give a much more informed view of the performance of the hedging strategy. In Fig 5, we see an example of using MJD to simulate the performance of a vanilla call. The analysis uses violin plots to visualize the distribution of outcomes. The width of the violin plot denotes the frequency of the outcome at a given payoff and thus the probability of the outcome.
During severe market dislocations, liquidity will be at a premium. Margin calls on OTM options can be difficult to manage, and for funds, will severely impact IRR. Balance sheet impacts from derivatives may trigger loan covenants, creating a cascade of effects. Therefore, evaluating strategy margin requirements and their impact on cash positions is an important aspect of evaluating strategies. Using the above paths, Fig 6 shows how each of the strategy margin requirements differ.Â
