Market Transparency and Fragility

No 11732, CEPR Discussion Papers from C.E.P.R. Discussion Papers

Abstract: We show that dealers' limited market participation, coupled with an informational friction resulting from lack of market transparency, can make liquidity demand upward sloping, inducing strategic complementarities: traders demand more liquidity when the market becomes less liquid, fostering market illiquidity. This can generate instability with an initial dearth of liquidity degenerating into a liquidity rout (as in a flash crash). In a fully transparent market, liquidity is increasing in the proportion of dealers continuously present in the market; however, in a less transparent market, liquidity can be U-shaped in this proportion and in the degree of transparency.
