北京发起了一项针对跨境资金流动和离岸金融流失的监管打击行动，将审查范围扩大到境外经纪商和富裕个人。监管机构威胁要对在内地无牌照运营的境外经纪商处以重罚，而税务官员则针对富裕公民，对其投资收益征收最高达 20% 的税款。

香港作为关键的离岸金融中心，正处于这场打击行动的中心。中信证券（Citic Securities）估计，此行动可能会影响高达 2500 亿港元（320 亿美元）的资产。因此，在有报导称部分银行已暂停为内地客户开设可用于境外投资的香港银行账户后，汇丰（HSBC）和友邦保险（AIA）的股价出现下跌。

这种监管压力使私人银行业感到寒意，迫使机构推迟内地活动并限制员工差旅。瑞银集团（UBS）推迟了其年中财富展望，而汇丰（HSBC）则劝阻香港私人银行家进行非必要的内地差旅。此次打击行动是由对去年创纪录的 8070 亿美元资金外流以及地方政府财政收入下降的担忧所驱动的。

Beijing has launched a regulatory crackdown targeting cross-border capital flows and offshore financial leakage, expanding its scrutiny to overseas brokers and wealthy individuals. Regulators have threatened severe penalties for overseas brokers operating on the mainland without licenses, while tax officials are targeting wealthy citizens with levies up to 20% on investment gains.

Hong Kong, a key offshore financial center, is at the center of this clampdown. Citic Securities estimates that the campaign could affect up to HK$250 billion ($32 billion) of assets. Consequently, major institutions like HSBC and AIA saw their shares tumble following reports that some banks suspended opening Hong Kong accounts for mainland clients. (Key numbers: 2500, 320)

This regulatory pressure has chilled the private banking sector, forcing institutions to postpone mainland events and restrict travel. UBS postponed its mid-year wealth outlook, while HSBC discouraged non-essential mainland travel for Hong Kong-based bankers. The crackdown is driven by concerns over record capital outflows of $807 billion last year and declining local government revenues. (Key numbers: 8070)
