摘要政策转向和信贷控制日趋严厉的情况下，市场主体进行了规避监管与追逐利润的自发性金融创新，同业业务由此迅猛发展起来。目前同业资产占商业银行总资产的比重接近15%。当前中国同业业务的主要类型包括存放同业、同业代付、买入返售等。同业业务发展有必然性与正面性，但其快速扩张造成了宏观政策效果弱化、放大了银行与金融体系的系统性风险、降低了金融监管体系有效性。为更好地规范与促进银行同业业务的发展，政府应尽快提高同业业务的标准化和透明度、将同业业务纳入统一授信体系并适当考虑资本金和风险拨备要求、进一步完善金融统计和会计制度、加快强化金融监管体系改革与健全宏观审慎管理框架，以及加强金融基础设施与配套体系建设。关键词：同业业务买入返售系统性风险监管AbstractDue to the adjustment of macro economy policies and the control ofcredit,themarket institutes have conducted self-improved financial innovations basedon avoidingregulatory and pursuing profits,which lead inter-bank institutionalfinancing boomingdramatically.Recently the ratio of the assets of inter-bankinstitutional financing to the totalassets of the banking system has come to nearly 15percent.The inter-bank institutionalfinancing includes loans to banks and otherfinancial institutions,inter-bank refinance fortrade and buying back the sale offinancial assets.Although the inter-bank institutionalfinancing has its rationality andconsistency,it might have led to systemic risks,weaken theeffectiveness of macropolicies and decreased the efficiency of the regulation system.TheChinesegovernment might implement a regulatory approach to deepen the supervisionandregulation of inter-bank institutional financing,accelerate the steps of financialreforms,build up a market-based financial infrastructure system,and establish asoundmacro-prudential management framework.Key words:Inter-bank institutional financing,Buying back the sale ofassets,Systemic risks,Regulation目录引言.1一、银行同业业务发展现状(二)存放同业存放.3(三)买入返售.(四)各项投资5二、银行同业业务的典型运作模式(一)存放同业的“存款拓展”...............................................(二)同业代付…(三)票据买入返售8(四)信托受益权买入返售.…9三、中国银行同业业务的风险分析四、同业业务的监管建议….13结论参考文献
