From Imagination to Exploration: Scenario Design in a Nonlinear World

The previously unimaginable has become routine. Events that once defined tail risk now occur with unsettling frequency, challenging the foundations of traditional risk management. Yet, many financial institutions continue to rely on traditional risk models built on historical data and stable correlations – tools fundamentally ill-suited for a world defined by structural breaks and nonlinear dynamics.

As practitioners often observe, “statistics won’t help you imagine what has never happened before.” This realization has led to a growing emphasis on creativity in stress testing. However, imagination alone is insufficient.

The challenge is not simply to envision extreme events, but to uncover how risks interact, amplify, and cascade across the financial system.

Today’s risk landscape is shaped by several distinct forces: rising oil prices and potential inflation; unfolding private credit crisis that could spread across other asset segments; and valuations of AI companies increasingly detached from fundamentals.

These risks can interact, especially when combined with other market trends. Tokenization growth increases behavioral volatility through panic selling. Senior CLO tranches, widely held by regulated institutions, could become a source of systemic liquidity stress if these securities are downgraded into high-yield territory, triggering need for capital across the board. This can happen just due to a shift in correlations in the collateral pool. Common in stressed environments, this can flatten the loss distribution shape.
