Then vs. Now: Historical Market Comparisons

44 comparisons that connect historical crises to modern risk frameworks, showing which mechanisms are genuinely analogous and which structural differences change the lesson.

A Then vs. Now comparison answers a precise question: which features of a historical market crisis are present in a modern context, and which are tied to the era in ways that make direct analogy misleading. Each page below examines one historical event and one modern risk frame, identifies the comparable mechanisms, and states the structural differences that limit or sharpen the analogy.

What Is a Then vs. Now Comparison?

A Then vs. Now page is not a prediction. It maps the structural overlap between a completed historical episode and a modern risk frame, identifies which mechanisms are genuinely comparable, and states which institutional or regulatory changes limit the analogy. The goal is better scenario questions, not borrowed historical certainty.

How to Use These Comparisons

Each page links to the primary case study for the historical event. Read the case study first to understand the historical mechanism precisely, then read the comparison to see which elements carry forward to the modern context. The comparison dimensions listed on each page are the analytical starting point: measure whether those dimensions are present in your current portfolio or market environment before treating the historical episode as a guide to current risks.

Because the modern side of every comparison changes over time, each page carries a last-reviewed date. A comparison based on stale current-state evidence is not useful. The pages in this series require a fresh sourced review of current data at publication and regular updates when conditions in the relevant dimensions change materially.
