Correlated liquidity shocks, ...nancial contagion and asset price dynamics

چکیده
Recent literature shows how the destabilising e¤ect of portfolio insurance activity on the price of the underlying asset depends on the liquidity of the asset market. We build a simple model where market timers shift capital around asset markets in order to exploit gains from temporary excess-volatility of asset prices. In this way, market timers increase the liquidity of asset markets reducing the excess volatility, while they increase the cross-market correlation, whereas long-ranged ...nancial contagion eventually occurs. We show how liquidity of asset markets, cross-market correlation and excess volatility of asset prices depend on structural parameters of asset markets.

This study develops a stress-testing framework to assess liquidity risk of banks, where liquidity and default risks can stem from the crystallisation of market risk arising from a prolonged period of negative asset price shocks. In the framework, exogenous asset price shocks increase banks’ liquidity risk through three channels. First, severe mark-to-market losses on the banks’ assets increase ...
متن کاملFinancial Fragility , Liquidity , and Asset Prices
We de ne a nancial system to be fragile if small shocks have disproportionately large e¤ects. In a model of nancial intermediation, we show that small shocks to the demand for liquidity cause either high assetprice volatility or bank defaults or both. Furthermore, as the liquidity shocks become vanishingly small, the asset-price volatility is bounded away from zero. In the limit economy, with...

A liquidity risk stress-testing framework with interaction between market and credit risks Eric Wong* and Cho-Hoi Hui* This version: April 11, 2011 Abstract This study develops a framework for stress testing banks’ liquidity risk, where liquidity and default risks can stem from market risk arising from asset price shocks. The risks are assumed to be transmitted through three channels. First, ba...
متن کاملAsset-based Contagion Models for Systemic Risk∗
We develop a structural model for the analysis of systemic risk in financial markets based on asset price contagion. Specifically, we describe a mechanism of contagion where exogenous random shocks to individual agents in an economy force portfolio rebalancing and endogenously impact asset prices. This, in turn, creates a chain reaction as downstream agents trade in reaction to price changes. I...
