城堡证券（Citadel Securities LLC）报告称，其印度业务的收入增长大幅下滑，原因是监管收紧后，现金和衍生品市场的整体交易活动减少。
Securities LLC reported a slump in revenue growth from its Indian operations as overall trading activity in the cash and derivatives markets declined following regulatory tightening.
根据数据服务提供商Tofler提供的一份文件，这家做市商在截至3月的财年中，营业收入增长约4%，达到417亿卢比（约合4.38亿美元）。由于成本上升，税后利润下降5%，至196亿卢比。这一业绩与上一财年形成鲜明对比——上一财年利润跃升41%，收入增长39%。
The market-maker’s operating revenue rose about 4% to 41.7 billion rupees ($438 million) for the fiscal year that ended in March, according to a filing made available by data service provider Tofler. After-tax profit fell 5% to 19.6 billion rupees as cost rose. The results are a sharp contrast from the previous fiscal year, when profit jumped 41% and revenue rose 39%.
这些数据进一步表明，印度资本市场在新冠疫情后的繁荣正开始降温。监管机构正着手遏制期权和期货市场的投机交易以保护散户投资者，这抑制了城堡证券和哈德逊河交易公司（Hudson River Trading LLC）等公司的增长。与此同时，外国机构投资者正发现其他市场更具吸引力，部分原因是美国人工智能交易的火爆以及卢比的贬值。
The figures offer more evidence that the post-Covid boom in India’s capital markets is starting to temper. Regulators are moving to curb speculative trading in options and futures to protect retail investors, crimping growth for firms like Citadel Securities and Hudson River Trading LLC. Meanwhile, foreign institutional investors are finding other markets attractive, partly because of the booming AI trade in the US and an erosion in the rupee.
