內容簡介:
包商銀行破產的處置過程中,我國監管部門首次未對中小銀行進行完全救助和擔保。本文考察了該例監管首次偏離了市場的長期剛性兌付預期處置的影響。基于雙重差分法,本文研究發現,包商銀行事件后,在同業存單市場,相比于系統重要性銀行,非系統重要性銀行(中小銀行)的融資成本(信用利差)顯著增加,同時融資比率下降。包商銀行事件導致的非系統重要性銀行融資困難具有顯著性和持久性,并引起部分中小銀行(如錦州銀行、恒豐銀行等)陷入融資困境。從事后角度分析,包商銀行事件引起了風險傳染,且可能一定程度上影響金融系統穩定。本文探索了其中的傳染機制,發現包商銀行事件降低了市場對未來政府救助非系統重要性銀行的信心。從事前角度分析,消除市場隱形擔保預期有助于提高定價效率、改善信貸分配。相比于系統重要性銀行,非系統重要性銀行股票價格下跌、債權人的監督意愿提高以及風險承擔降低。
Upon assuming control of Baoshang Bank, Chinese bank regulators announced that they would eschew bailing out large creditors of this city-level distressed bank in full. This paper investigates the consequences of this unexpected deviation from the long-standing full bailout policy. Employing a difference-in-differences methodology, we find that this event significantly increased credit spreads and decreased the funding ratio of negotiable certificates of deposit (NCD) issued by systemically unimportant (SU) banks relative to those issued by systemically important(SI) banks. The deterioration of funding conditions for other SU banks is economically significant and persistent, resulting in the distress of those small banks. We provide additional evidence to show that the underlying mechanism of this contagion and ex post financial instability is a decline in market confidence regarding future bailouts for SU banks. Ex-ante, however, it is found that the induced implicit non- guarantee improves price efficiency and credit allocation, lowers equity prices, strengthens creditors' monitoring, and reduces the risk-taking among SU banks relative to SI banks. Finally, additional evidence on credit line extension and utilization is presented to illustrate the real effects of this contagion caused by the unanticipated bailout policy change.
