绿色债券.上|全球新趋势 香港可成绿色金融中心

对全球及未来一代而言,气候变化是最严重的威胁之一,全球日益关注当中涉及的风险,「绿色金融」(Green Finance)亦开始走入公众视线,其中绿色债券(Green Bond)便是常见的金融工具。中国自2016年起连续四年成为绿色债券发行量最大的国家,而现时全球的金融中心在推动绿色债券上亦不遗余力,站在发展前沿的香港亦不例外,特区政府除了积极发行绿色债券外,还致力推出不同的便利措施,吸引企业来港筹集资金,包括参与可持续发展并具有环境效益的投资。然而,绿色金融到底是解决全球暖化的关键,还是只是随波逐流、迎合金融业趋势的工具?两者之间又该怎样取得平衡?

Do banks still monitor when there is a market for credit protection?

The rise of credit default swaps (CDS) provides creditors with a market-based approach to obtaining protection, but it can also affect lenders' monitoring of the borrowers. We find that after CDS begin trading on a given firm, new loans to that firm are less likely to require collateral and have less strict financial covenants, even controlling for endogeneity. The effects are stronger when lenders have easier access to CDS, for safer firms, credit lines, and performance-based covenants. Our evidence is consistent with the theory that the introduction of CDS trading makes loan contracting more effective for better quality borrowers.
