In two months, 3.7 billion won in fees were collected, and the trading volume of South Korean leveraged ETFs plummeted by 90% after regulatory intervention

Retail investors in South Korea are shifting their focus from the growth story of asset management companies to market stability issues in the eyes of regulators, surrounding high-leverage trading of Samsung Electronics and SK Hynix.Since their debut on May 27, the first batch of single-stock leveraged products in South Korea has quickly become one of the most crowded trades in the current semiconductor rally of the Korean stock market. Sixteen single-stock ETFs and two ETNs designed around Samsung Electronics and SK Hynix allow investors to make directional bets of about 2 times on a single stock. The launch of these products coincided with the warming of the AI storage cycle, leading to a surge of retail funds into the market, pushing the total assets of the Korean ETF market to a historical high at one point.Winners on the fee side quickly emerged. Estimated by net asset size and fee rates, these single-stock leveraged ETFs generated nearly 3.7 billion won in management fees after about two months of operation. Samsung Asset Management took the lion's share due to the scale advantage and higher fee rates of its KODEX products, while Future Asset offered lower fees to gain market share. Early data from Korean media has shown that Samsung and Future Asset together account for over 90% of the net assets of such products, with liquidity further concentrating on leading products.However, this fee feast has also come with significant side effects. In mid-July, the South Korean Financial Services Commission stated that the market value and trading volume of single-stock leveraged products rose rapidly after their launch, with the weight of Samsung Electronics and SK Hynix in KOSPI once reaching 52%. Regulators also pointed out that the volatility of global storage stocks has significantly increased, and the high volatility of individual stocks like SK Hynix and Samsung Electronics, combined with product rebalancing trades, could amplify market shocks.Subsequently, South Korean authorities accelerated the tightening of regulations. Starting from July 31, the minimum margin requirement for individual investors investing in such products was raised from 10 million won to 30 million won, and cash was required to meet this requirement, with alternative securities no longer accepted; regulators also suspended the launch of related new products, restricted advertising, and strengthened spread management and investor education.There are signs that trading enthusiasm has cooled. Data from the Korean Exchange shows that after the introduction of new regulations, the daily trading volume of the 16 related single-stock leveraged/inverse ETFs dropped from about 10 to 12 trillion won (peaking at 15 to 20 trillion won) to around 1 trillion won (on August 3-4), and on August 5, it fell to as low as 919.8 billion won (first time below 1 trillion). There has been a slight rebound recently, with the trading volume of the 16 related ETFs at about 7.45 trillion won on July 27.

Hong Kong police updated on the virtual currency Fun Coffee scam, with total losses rising to approximately HKD 104 million

According to Hong Kong 01, the Hong Kong police updated information regarding the virtual currency Fun Coffee scam, revealing that as of August 5, a total of 255 related reports had been received, an increase of 30 from earlier, with total losses rising to approximately HKD 104 million. In addition, the Macau police arrested two women involved in 9 cases amounting to about 3.6 million Macau patacas.Regarding TVB artists who have hosted activities related to the Fun Coffee scam, the Hong Kong police stated that during the investigation, they would definitely contact the victims and relevant individuals to identify the mastermind behind the scam and their roles. Fun Coffee claims to be a large coffee investment enterprise in Phu Quoc, Vietnam, with a capital scale exceeding USD 1 billion. It entered the Hong Kong market by the end of 2025, packaging its image through marathons, banquets, social events, distributing flyers, and inviting artists to promote it, while registering a company, opening offices, and stores in Hong Kong. The actual operation was to lure citizens into downloading the app to complete tasks under the guise of investing in high-tech coffee equipment, gene optimization technology, and agricultural equipment, using Tether (USDT) and other cryptocurrencies for deposits. The platform promised annual returns of up to 197%--278%, with higher returns for larger amounts and longer deposit periods, and set up a commission structure to encourage recruitment. In July 2026, the Hong Kong Securities and Futures Commission listed it as a suspicious investment product. In late July of the same month, the app suddenly ceased operations, withdrawals became impossible, customer service went offline, and the offices and stores were vacated, leading to the collapse of the scam.

CXMT is currently priced at $7.80, with an unrealized profit of about $1,938,000 (89.7%), and the liquidation price is only $0.507.Based on the current position and a static rate of -0.2430%, this whale can earn about $31,000 in funding fees in the next hour; if maintained for 24 hours, this corresponds to about $743,000.This whale currently still has 7 buy orders not labeled as "only reducing positions" between $6.01 and $6.41, planning to continue buying 98,000 CXMT, with a nominal amount of about $609,000, and has not chosen to cash out the existing long position.

Vietnam's "Fun Coffee" is involved in a virtual currency scam explosion in Hong Kong, with thousands deceived and over 1 billion Hong Kong dollars involved

According to a report by Hong Kong 01, "Fun Coffee," which claims to be rooted in Vietnam, just entered Hong Kong at the end of 2025 and was warned by the Hong Kong Securities and Futures Commission in July 2026 for being a suspicious investment product. The company appears to be investing in the coffee business, but in reality, it is a virtual currency investment scam with annual interest rates as high as 222%, ultimately "collapsing" at the end of July.The victim group has over 370 people, with each person defrauded of hundreds of thousands of dollars. Multiple investment groups combined have a total of 4,000 people involved, with funds exceeding 1 billion Hong Kong dollars. A middle-aged woman in her 50s claims that she unknowingly became a shareholder and director of one of Fun Coffee's Hong Kong registered companies, and she has over a hundred "downlines." After being contacted by reporters, she has gone to the police to report the case. The police have received 115 reports, which have been handed over to the Commercial Crime Bureau's fraud investigation team for follow-up.The report states that Fun Coffee held a marathon event in Hong Kong at the end of last year, inviting artist Yuen Siu Cheung to host and distributing anti-fraud leaflets for promotion in various districts. The company's headquarters in Kowloon Bay and its storefront in Mong Kok are now empty, with notices of unpaid rent posted. The Securities and Futures Commission issued a warning on July 13, and the Vietnamese Ministry of Public Security also warned in May that it is suspected to be a Ponzi scheme.
