We propose an empirical model to decompose BS quotes into expected and unexpected components. To estimate both unobservable constituents of BS spreads, we solve a signal extraction problem using a particle filter. Our empirical findings show that unexpected changes of BS spreads are linked to systemic risk. Shocks to aggregate liquidity are also important to explain regime shifts. Sovereign risk and risk aversion are relevant factors explaining expected fluctuations.application/pdfengAtribución-NoComercial-SinDerivadas 3.0 EspañaInterbank riskBasis swapSystemic riskLiquidityParticle filterworking paperG01G12G15G32DT/0000001551
