(Bloomberg) — Pony Mas Tencent Holdings Ltd. has been put on notice.Asias largest conglomerate was censured by Chinas antitrust watchdog on Friday as Beijing expands a crackdown that began with Jack Mas online empire.The token fine is just the beginning. Chinas top financial regulators see Tencent as the next target for increased supervision after the clamp down on Jack Mas Ant Group Co., according to people with knowledge of their thinking. Like Ant, Tencent will probably be required to establish a financial holding company to include its banking, insurance and payments services, said one of the people, seeking anonymity as the discussions are private.The two firms will set a precedent for other fintech players on complying with tougher regulations, the people added.Such a move would mark a significant escalation in Chinas campaign to curb the influence of its technology moguls, days after Premier Li Keqiang pledged at the National Peoples Congress to expand oversight of financial technology, stamp out monopolies, and prevent the unregulated expansion of capital.We will continue to adapt to changes in the regulatory environment, which we view as beneficial to the industry, and will seek to ensure full compliance, Tencent said in an emailed statement following the fine by the antitrust watchdog. The company declined to comment on financial regulatory matters.The China Banking and Insurance Regulatory Commission didnt immediately respond to a request seeking comment.A progression of rules unveiled in the past six months has taken aim at the dominions built by Chinas most successful online entrepreneurs. The first blows fell on Jack Ma when Ants $35 billion initial public offering was torpedoed at the last minute, followed by an antitrust probe into Alibaba Group Holding Ltd.While Pony Ma doesnt have the kind of high-profile globally that Jack Ma does, he is considered one of Chinas most accomplished entrepreneurs within the country. The 49-year-old year has built Tencent into the most valuable company in Asia on the strength of its social medis and games businesses. Ma is the wealthiest person in China.Tencent has already seen collateral damage from the new regulations, though investors had shrugged this off, pumping up the stock even as Alibaba was punished. Its 26% advance over six months contrasts with a 15% slump for Jack Mas e-commerce behemoth, which owns a third of Ant. Shares of Tencent climbed to a record on Jan. 25, valuing it at roughly $950 billion.The stock fell 4.4% in Hong Kong Friday. Shares of Tencent investor Naspers and its unit Prosus also declined. Spreads on Tencents 2.39% dollar bond due 2030 widened 9 basis points, while notes issued by fellow Chinese tech giants including Meituan and JD.com Inc. also weakened, according to traders.Along with Ant, proposed rules to break up market concentration in digital payments and rein in consumer lending online will damage prospects for Tencents WeChat Pay and its wider fintech business.A diktat to fold those operations into a holding company that could be regulated more like a bank would potentially further curb its ability to lend more and expand as rapidly as it has done in recent years.Tencents fintech business had revenue of about 84 billion yuan ($13 billion) in 2019, accounting for 22% of the total and making it the largest earnings driver after online entertainment. Thats about 70% of Ants revenue for the year.Valuation HitAfter Ants IPO suspension, the central bank directed the Hangzhou-based firm to turn itself into a financial holding company, subjecting it to capital restrictions, the need for fresh licenses and ownership scrutiny. The overhaul could slash the financial juggernauts valuation by about 60% from the $280 billion it was pegged at last year, Bloomberg Intelligence analyst Francis Chan has estimated.Tencent meets the parameters for such treatment, including the threshold for assets and having businesses that straddle at least two financial sectors.What Bloomberg Intelligence SaysFintech is neither Tencents fastest-growing nor its most profitable business, minimizing the immediate financial impact, yet the turn of events may signal an era of more rigorous regulatory oversight, with strong echoes of Alibabas shifting fortunes.– Vey-Sern Ling and Tiffany Tam, analystsClick here for the researchOutside of financial services, Tencent and its peers are exposed to further action on the antitrust front.On Friday, the regulator fined Tencent, search leader Baidu Inc., ride-hailing giant Didi Chuxing and a clutch of others 500,000 yuan each — the maximum under current rules — for past acquisitions and investments, stepping up its crackdown.Alibaba is also being probed and the watchdog is considering a record fine exceeding the $975 million that Qualcomm Inc. paid in 2015, Dow Jones has reported.Premier Li balanced his strictures last week with an assurance that Beijing supports the innovation and development of platform companies, as long as they fall in line with the countrys laws.Recent measures to rein in fintech firms werent aimed at a specific company, a senior regulatory official has said, and instead focus on creating a stable environment for private enterprise to grow.Yet, Beijing has a penchant for making examples of its biggest companies to force others to fall in line with changing priorities. All three of the nations financial watchdogs have made it their primary goal this year to curb the reckless push of technology firms into finance. And theres little doubt of the sway Pony Mas conglomerate has built in finance.Its WeChat super-app boasts more than a billion consumers that use it for everything from chatting with friends to booking taxis and buying groceries. WeChat Pay accounts for almost 40% of the countrys mobile payments market, second only to Alipay, according to iResearch.Tencent with three other major tech companies — Alibaba, JD.com and Baidu — together control over 40 financial licenses through acquisitions or investments, according to Xinhua News Agency, which cited 01caijing.(Updates with background on Pony Ma in ninth paragraph.)For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2021 Bloomberg L.P.
