Delta hedging aligns the portfolio of risky and safe assets in line with the delta of the option. However, when risk is endogenous, delta hedging can inject feedback loops into market prices, so that delta hedging can lead to large market moves. The 1987 stock market crash is brought in as an illustration.","PeriodicalId":243382,"journal":{"name":"Risk and Liquidity","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123906643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The securitisation vehicles of Northern Rock left it particularly vulnerable to the deleveraging by wholesale creditors in 2007, and poses many pertinent questions for the management of financial risks in an era when banking and capital markets are intertwined.","PeriodicalId":243382,"journal":{"name":"Risk and Liquidity","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124719706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
