The displacement-dominant call holds and has firmed, with one addition to its mechanism: since late July, junta military pressure, not only Chinese-driven enforcement, has been pushing Myawaddy compounds into territory protected by the DKBA. Operators in Kyauk Khet relocated within weeks under armed escort, which confirms that hitting a location in Myawaddy district displaces capacity rather than removing it. The brief underweighted conflict as a relocation engine. That strengthens the scenario 1 read and modestly supports the fragmentation logic of scenario 3, without changing the call. The trapped-worker count, Sri Lankan arrest totals and STR volumes have no fresh data. The pivotal question is unchanged: whether Naypyidaw, the DKBA, or Phnom Penh ever targets owners and assets rather than premises.

DISPLACEMENT — On track — Kyauk Khet operations moved en masse into DKBA-held villages instead of shutting down.
CONFLICT VECTOR — Off-model — Civil-war violence, not only enforcement, is now a primary relocation driver.
DISCRIMINANT — In band — No host-state action against protected owners, and an armed group is actively sheltering operators.

Host-state prosecution of protected compound owners — Quiet
Trapped-worker count in Myanmar border scam centres — Watch
Sri Lankan full-year 2026 scam arrests — Watch
AUSTRAC and STRO scam-related STR volumes — Watch
Armed-group realignment against scam patrons — Quiet

Forecast: Specific compounds shrink, but total capacity moves and spreads rather than disappears.

Arrests are real but narrow. Cambodian banks and the Myawaddy border trade take the hardest hits.

What this changes for you

Capital. Your exposure to Cambodian banking rails carries live sanctions risk after OFAC designated Heng Feng Cambodia Bank and 28 other targets.
Operations. Your suspicious-transaction reporting load is rising, AUSTRAC and Singapore STRO data showed a 63% increase in scam-related reports in 2025, and fragmentation into AI-enabled micro-cells widens the surface further.
Positioning. Geographic relocation into Sri Lanka, Laos, and maritime Southeast Asia means your next-geography exposure is expanding even as headline compound counts in Myanmar fall.

Drivers

Enforcement is selective, not systemic — Beijing targets scams harming Chinese nationals and leaves foreigner-targeting operations intact. — Chen Zhi was extradited 6 January 2026 and roughly US$15 billion in cryptocurrency confiscated, yet host-state-protected compounds remain operational because enforcement is calibrated around victim nationality, not industry elimination.

Networks adapt and relocate — Operators bypass cutoffs and shift capacity rather than shutting down. — Compound bosses switched to diesel generators and Starlink to defeat Thai utility cutoffs. Capacity is redistributing to Laos, Sri Lanka, and maritime Southeast Asia, sustaining an estimated $40 billion annual industry.

Host-state complicity blocks degradation — Genuine collapse requires host states to prosecute protected owners independently. — The majority of Cambodia's compounds are assessed as operating with government support. Cambodian agencies conducted 2,709 location raids in two weeks but remain largely absent structurally; Beijing drives all high-profile action.

What we expect

Displacement dominant, selective degradation (Likely) — High-profile decapitations (Chen Zhi, Kok An network, executions) continue and specific fixed compounds shrink, but aggregate industry capacity relocates and fragments rather than collapses. The estimated $40 billion annual industry persists, redistributed. Degradation is real at the node level; the network is resilient at the system level.

Genuine systemic degradation (Unlikely) — Host governments, especially Cambodia and the Myanmar junta/militias, move against politically protected compounds, not just China-directed targets, plus sustained multilateral pressure. Analysts judge the status quo unlikely to change absent extremely high, sustained international pressure, given the majority of Cambodia's compounds operate with government support.

Cascading relocation (Possible) — Aggressive but selective enforcement accelerates fragmentation into AI-enabled micro-cells across maritime Southeast Asia, South Asia, and Africa, worsening detection and expanding the victim base and bank-compliance surface. A net-negative outcome where enforcement optics rise while harm globalizes through scam-as-a-service arrangements.

What to watch

Host-state prosecutions — of protected owners without a prior Chinese request
Trapped-worker count — sustained decline well below 5,300 reported near Thai border
STR volumes — beyond the 63% rise already recorded by AUSTRAC and STRO
Sri Lanka arrests — full-year 2026 figure against roughly double 2024 or 2025
Starlink and generator procurement — by operators in new relocation destinations

Framing

Enforcement against Mekong scam compounds has genuinely intensified since late 2025, driven primarily by Chinese pressure, with the Chen Zhi arrest and OFAC designations decapitating apex owners. But the enforcement is selective and security-centric: it prioritizes scams harming Chinese nationals. The dominant system response is relocation and fragmentation, not degradation. The industry generates an estimated $40 billion annually per UNODC and persists, redistributed.

Key judgments

The mechanism — Chinese enforcement is real but calibrated to protect Chinese nationals, leaving foreigner-targeting operations comparatively undisturbed. Node-level degradation coexists with system-level resilience: hitting one location displaces networks rather than eliminating them.
For regional banks — OFAC designation of Heng Feng Cambodia Bank and the Prince Group converts a criminal-justice problem into a correspondent-banking and sanctions-compliance problem. AUSTRAC and Singapore STRO data showed a 63% increase in scam-related suspicious transaction reports in 2025 versus the prior year.
For border economies — The Myawaddy corridor bears the sharpest physical shock because legitimate trade and illicit economy share the same utility arteries. Thai utility cutoffs hit hospitals, schools, and the 100 billion baht annual border trade while scammers switch to diesel generators and Starlink.
The discriminant — Genuine degradation requires host-state authorities, not Chinese envoys, to independently seize assets of and prosecute owners of politically protected compounds. Analysts assess the majority of Cambodia's compounds as operating with government support.

What could change our mind

Host-state authorities (Cambodian or Myanmar) independently seize assets of and prosecute owners of politically protected compounds without a prior Chinese prosecution request — Independent host-state prosecution of protected owners moves toward Scenario 2 (genuine systemic degradation). Continued absence, with Cambodian agencies remaining largely absent during developments while Beijing drives all high-profile action, confirms Scenario 1 (displacement dominant, selective degradation).
Sri Lankan scam-related arrests reported for full-year 2026 — An annual figure exceeding 600 cases, roughly double 2024 or 2025, evidences accelerating displacement into new destinations and moves toward Scenario 3 (cascading relocation). A figure holding near prior-year levels weakens the cascade case and keeps Scenario 1 modal.
Count of trapped workers reported in Myanmar scam centres near the Thai border — A sustained decline well below the more than 5,300 currently reported would evidence real capacity reduction toward Scenario 2. A stable or rising count, with centres resuming activity elsewhere in Myawaddy district after enforcement, confirms displacement under Scenario 1.
Regional scam-related suspicious transaction report volumes reported by AUSTRAC and Singapore's STRO — A further increase beyond the 63% rise recorded in 2025 evidences an expanding bank-compliance surface consistent with fragmentation and victim-market rotation under Scenario 3. A plateau or decline would support Scenario 2 systemic degradation.

Who matters

Chinese Ministry of Public Security — Primary enforcement driver via Lancang-Mekong architecture and extraterritorial coercion — Calibrated to prioritize cases harming Chinese nationals; leaves foreigner-targeting operations comparatively undisturbed
US Treasury / OFAC — Sanctions instrument targeting corporate and banking rails (Prince Group, Kok An, Heng Feng Cambodia Bank) — Designations create de-risking risk but cannot compel host-state prosecution of protected nodes
Cambodian authorities — Host state conducting headline raids (2,709 locations in two weeks, February 2026) — Largely absent structurally; majority of compounds assessed as operating with government support
Myanmar junta / Karen Border Guard Force — Territorial hosts of Myawaddy compounds (KK Park, Shwe Kokko) — Scam centres generate significant revenue for both ethnic armed groups and the military junta, incentivizing protection
Thai government — Enforcement instrument via utility/telecom cutoffs; victim market — Cutoffs blunt; scammers bypass via generators and Starlink; scam anxiety electorally salient after February 2026 election

What changed

Used to be: Scam compounds were concentrated in fixed Mekong-region nodes with identifiable apex owners and largely stable banking rails.

Now: Apex owners are arrested or designated, but capacity has redistributed into fragmented, AI-enabled cells across Laos, Sri Lanka, and maritime Southeast Asia, with victim targeting rotating toward American and European marks.

Chen Zhi was extradited on 6 January 2026 and approximately US$15 billion in cryptocurrency was confiscated. OFAC designated 29 targets including Heng Feng Cambodia Bank and the Prince Group. Cambodian authorities conducted raids on 2,709 locations over two weeks in February 2026. Taken together, these are the most visible enforcement actions the region has seen, but the industry they are targeting generates an estimated $40 billion annually and the enforcement is selective.

The selectivity is the critical fact for you. Chinese enforcement prioritizes cases harming Chinese nationals and leaves foreigner-targeting operations comparatively undisturbed. Compound operators have already adapted, switching to diesel generators and Starlink to defeat Thai utility cutoffs and relocating workers and equipment to new jurisdictions. The majority of Cambodia's compounds are assessed as operating with government support, which means Cambodian agencies remain structurally absent even as Beijing drives high-profile action.

The consequence is that your compliance surface is expanding, not contracting. Victim targeting is rotating toward American and European victims. Suspicious transaction volumes are rising. And the new geography, Sri Lanka, Laos, maritime Southeast Asia, is precisely where enforcement coordination is thinnest.

What would prove us wrong

Host-state authorities prosecute protected compound owners independently — If Cambodian or Myanmar authorities seize assets of and charge politically protected compound owners without a prior Chinese prosecution request, the displacement forecast tips toward genuine systemic degradation, the outcome the forecast currently judges unlikely.
Beijing expands enforcement to foreigner-targeting operations — The entire forecast rests on Chinese enforcement remaining calibrated to protect Chinese nationals; a shift to dismantling the broader economy would remove the selective-focus mechanism that keeps aggregate capacity intact.
Domestic political rupture removes state protection from compounds — A leadership change or factional purge in Cambodia or Myanmar that strips protected patrons of their position is not modeled, but would independently collapse the host-state complicity that holds the displacement scenario together.

What it means for you

Treat the OFAC list as a live correspondent-banking screen, not a one-time check — Heng Feng Cambodia Bank and the Prince Group are designated, and 27 other targets were hit in the same action, any payment touching these rails creates sanctions exposure regardless of underlying transaction intent.
Do not read falling compound counts as falling risk — Node-level degradation is real, but the system is relocating: the discriminant that would confirm genuine collapse, host-state prosecution of protected compound owners, has not been met.
Watch Sri Lanka arrest figures for the full year 2026 — An annual figure exceeding 600 cases would evidence the cascading-relocation scenario and signal that your Sri Lanka and South Asia compliance posture needs immediate uplift.

Methodology

Confidence is moderate. The direction of travel is strongly corroborated across independent enforcement, academic, and NGO sources. Limiting factors are measurement error (compound populations and revenue are proxies, almost certainly under-reported) and difficulty observing deliberately concealed relocation in real time. This analysis is consistent with the standing Thailand-Cambodia ceasefire call and does not update it.
