Risk Targeting and Policy Illusions—Evidence from the Announcement of the Volcker Rule
研究了沃尔克规则宣布对美国银行控股公司的影响，发现受影响的银行虽减少了交易资产，但通过提高资产风险来维持风险目标，并未降低整体风险承担。
We analyze the Volcker Rule’s announcement effects on U.S. bank holding companies. In line with the rule and the banks’ public compliance announcements, we find that those banks that are affected by the Volcker Rule already reduced their trading books relative to their total assets 2.34% more than other banks. However, the announcement of the rule did not reduce the banks’ overall risk taking. To keep their risk targets, the affected banks raised the riskiness of their asset returns. We also find some evidence that the affected banks raised their trading risk and decreased the hedging of their banking business.
