N°23-68: Price Formation in the Foreign Exchange Market

We study joint price formation in the dealer-to-dealer (D2D) and dealer-to-customer (D2C) segments of the foreign exchange (FX) market, both theoretically and empirically. Our theory accounts for dealer heterogeneity, market power, and non-exclusive customer-dealer relationship and shows that several statistics of the cross-section of D2C quotes help predict D2D prices and liquidity. In particular, D2D prices are negatively related to cross-sectional covariance between D2C mid-quotes and spreads, contrary to predictions of other theories of two-tiered markets. Our predictions are confirmed empirically using unique proprietary D2C data. Model calibration reveals and quantifies the FX market’s inelasticity and non-competitiveness.
