Thailand's Slow Progress in Mauerberger Network Investigations

Read The Diplomat, Know The Asia-Pacific One year after the South African national Benjamin Mauerberger and his network were first exposed, not one intermediary has been charged. Benjamin Mauerberger, a South African national allegedly involved in financial networks connected to online scamming operations in Cambodia. On their Whale Hunting blog in August 2025, Tom Wright and Bradley Hope began exposing the vast financial network built by the Cambodian businessman Yim Leak and the South African Benjamin Mauerberger, known in Bangkok as Ben Smith. In May 2026, the U.S. House Select Committee on China published a bipartisan report, “Crime, Corruption, and Power.” The report claims that a “South African fixer” is alleged to have operated between Cambodia’s crime hubs, developers linked to the Chinese Communist Party, and Thailand’s elite economy, laundering enormous illicit proceeds into Thai markets. All three footnotes cite Wright and Jacob Sim, a visiting fellow at Harvard University who specializes in Southeast Asia’s scam economy. Thailand appears in that report twice. The first mention of the country is as a victim of the regional scam economy, with domestic losses put above 115 billion baht ($3.5 billion) a year, according to a 2025 estimate by Global Anti-Scam Alliance. The second is the market where many of the profits from Southeast Asian scam centers come to rest. By my own count, those proceeds sit in more than 20 listed and unlisted Thai companies, in holdings worth over 26 billion baht ($778 million). Thailand has become rather good at finding this money, but it has not begun to prosecute the people who helped to move and launder it. The revelations have implicated a sitting member of the government. Vorapak Tanyawong, a former president of Krungthai Bank, was appointed deputy finance minister on September 19 of last year. He resigned 33 days later, after Whale Hunting reported that he had once been listed as an adviser to Cambodia’s BIC Bank, whose chairman is Yim Leak, and alleged that his wife had received $3 million in cryptocurrency from a Chinese-Cambodian criminal network. Vorapak, who has not been charged with any offence, has denied all of it. He said he had met Yim Leak but never advised or worked for BIC, called the reporting a smear campaign, and announced he would sue for defamation. I should disclose where I stand. I am a former investment banker who has spent the past year documenting this network’s footprint in Thai capital markets on my blog, fringer.co. Vorapak is the plaintiff in the criminal defamation suit I am currently defending. I have also received cease-and-desist letters from Chartered Group, Capital Asia Investments, and others connected to them. And I now advise the parliamentary committee trying to extract answers from the regulators. So here is my scorecard for the Thai agencies involved, ranked from best to most disappointing. The Anti-Money Laundering Office deserves praise. Two orders, in December 2025 and April 2026, provisionally froze 102 items worth roughly 20.4 billion baht ($610 million). This included shares in listed companies including Bangchak Corporation and Finansia X, securities accounts, cars, loan claims, and a yacht. These are temporary seizures, not forfeitures, and the parties can petition the court to get the assets back. By Thai standards, it is still remarkable work. The Department of Business Development has moved against illegal nominees, and the Central Investigation Bureau has broken up scam compounds and traced laundering routes through Cambodia-based Huione Pay. Huione Pay’s parent company Huione Group was severed from the U.S. financial system in October 2025 due to its alleged role as a “critical node” for laundering proceeds from transnational crimes and scams. In February 2026, the bureau obtained arrest warrants for Mauerberger and his Thai wife, Cattaliya Beevor. These warrants deserve a closer read, however. They rest on an alleged investment fraud dating to 2016, in which one foreign investor claims losses of more than 1 billion baht. The money-laundering counts attached are predicated on that private fraud, not on the scam-compound proceeds. Mauerberger is reported to have left Thailand last September, and his lawyer has described the case as a civil dispute over a share purchase agreement. Which brings me to the Securities and Exchange Commission (SEC). In July 2026, the parliamentary committee sent it 20 questions, asking for each to be marked done, in progress, or not started, with a timeline. The six-page reply answered one question, on new know-your-customer guidelines, directly. It used the phrase “currently under examination” six times, and attached a deadline to none of the 20 questions. It did not once mention the efforts of Singapore’s police and central bank, who in March arrested two directors of Capital Asia Investments (CAI), and froze more than S$160 million. CAI is the fund manager behind several of the committee’s questions about potential securities law violations that the SEC should duly investigate. What it has produced instead is enforcement at the edges. In June, it referred Finansia Syrus Securities to police over deficiencies in client identification; in July and August, it also referred Yim Leak to police over shareholding disclosures filed late or not at all. One of those included a finding that he was the beneficial owner of a fund that crossed 5 percent in the advertising company VGI. These are not insubstantial, but amount to mere filing offences. The substantive questions remain unanswered. In August 2025, a rights offering lifted CAI’s stake in the brokerage group Finansia X from 24 percent to 44 percent without triggering a mandatory tender offer. The top four shareholders hold about 64 percent between them. And in April this year, Alpha Chartered Energy, whose stake in the energy company Bangchak Corporation AMLO was frozen in December, was permitted to vote at Bangchak’s annual meeting on a bylaw amendment written to exclude shareholders in exactly its position. The amendment failed. What exactly is the SEC waiting for? I believe three things need to change. First, capital-market conduct has to be treated as a criminal case in its own right, rather than as an appendix or afterthought to asset freezes. Concealed control of listed companies, undisclosed acting in concert, and share issues structured to avoid tender-offer obligations are all offences under Thailand’s Securities and Exchange Act. Freezing a block of shares does not establish who acquired it, or through whom. The second is to go after the intermediaries. An apparatus this size cannot be built by two foreigners on their own. Somebody arranged the placements, somebody cleared the trades, and others sat in the board meetings that approved them. Whether or not those people knew what they were facilitating, these are all offenses under Thai law. So far, no one important has been cha
