January 15, 2015, 09:30 GMT. Swiss National Bank announced removal of EUR/CHF 1.20 floor that had operated for 41 months since September 6, 2011. EUR/CHF collapsed from 1.20 to as low as 0.85 within minutes — a 30% currency move in normal market hours with substantial liquidity vacuum. Spread expansion across CHF crosses reached substantially extreme proportions during the liquidity vacuum period. Multiple retail FX brokers experienced solvency events including Alpari UK administration plus FXCM emergency funding requirement. We pulled the January 15 spread reconstruction, the broker failure dynamics, and what 11 years post-event reveal about retail FX risk framework.
