Debt-Deflation Spiral Simulator

Interactive financial-crisis feedback loop: a falling asset price shrinks collateral, credit contracts, output falls, and leveraged fire-sales feed back into the price — tune leverage, collateral sensitivity and capital buffers to see whether the loop dampens or spirals into a crash.

Financial crises rarely start as a single collapse — they start as a feedback loop. A falling asset price shrinks the collateral behind outstanding loans; banks pull back credit to compensate; the shortage of credit slows the real economy and forces leveraged holders to sell assets to deleverage; those sales push the asset price down further, restarting the cycle. This simulator isolates that loop into three linked indices — Price, Credit, Output — and lets you tune the shock, how tightly credit is tied to collateral, how much leverage forces fire-sales, and how large a capital buffer the banking system holds. Small shocks with a healthy buffer damp out; large shocks with high leverage and a thin buffer spiral into a full debt-deflation crash, the mechanism behind the Great Depression, the 2008 global financial crisis, and the 1997 Asian crisis.

⚙ Under the hood

Trigger a shock to a linked Price–Credit–Output feedback loop and watch collateral-driven credit contraction and leveraged fire-sales either damp out or spiral into a full debt-deflation crash. Tune shock size, collateral sensitivity, leverage and Basel-style capital buffers.
