Cambodia USDT Guide: Dollarization, Bakong, KHQR and the 70% Fee Cut

Cambodia and the Dollarized Economy

Cambodia is unusual among Southeast Asian economies in how thoroughly it operates in US dollars. The riel is the official currency, but in daily commerce — in Phnom Penh shops, Siem Reap restaurants, Sihanoukville businesses — US dollars circulate as freely as the local note. Smaller change is given in riels; larger amounts in dollars. ATMs dispense both. Bank accounts are commonly held in dollars. By 2024, despite a sustained NBC effort to promote riel usage through the Bakong system, transaction value still ran roughly 70% in dollars.

This dollarization shapes how Cambodians interact with USDT. In economies like Argentina or Venezuela, USDT is appealing primarily as a dollar substitute — a way to hold dollar-denominated value when the local currency is unstable. In Cambodia, dollars are already the local money. USDT here serves a different purpose: it is the most efficient way to move dollar value across borders, in and out of the country, without the friction and cost of correspondent banking.

The other distinctive Cambodian fact is the size of the unbanked population. Roughly 70% of adults do not have a traditional bank account. Mobile wallets — Wing, TrueMoney, Pi Pay, ABA Pay — have filled that gap. The combination of high mobile penetration, low banking penetration, and an established culture of dollar usage has created favourable conditions for USDT to enter the corridor.

Bakong, KHQR and the Domestic Payment Rails

The National Bank of Cambodia launched Bakong in October 2020 as a blockchain-based real-time payment system. Built on the Hyperledger Iroha framework with technical support from Japanese fintech firm Soramitsu, Bakong allows instant peer-to-peer transfers between participating banks and e-wallets. By 2024, the system had registered over 30 million wallets — substantially exceeding Cambodia's population, partly because individuals hold multiple accounts and partly because tourist usage has grown via the Bakong Tourists App. Bakong processed approximately 608 million transactions worth $104.81 billion in 2024, equivalent to 330% of Cambodia's GDP.

KHQR is the national QR code standard launched in July 2022, also operated through the Bakong infrastructure. It is interoperable across all participating institutions: a single QR code on a merchant's counter accepts payment from any connected wallet or banking app. KHQR has been cross-linked with payment systems in South Korea, Japan, Malaysia and with Alipay+, allowing tourists from those markets to pay Cambodian merchants using their domestic apps, with automatic settlement in Khmer riels.

For USDT remittance flows, Bakong and KHQR are the rail that delivers the fiat side of the conversion. A P2P counterparty receiving USDT from an overseas worker pays out the dollar or riel equivalent through their bank account, and that fiat moves through Bakong to the recipient's wallet — typically settling in seconds. The total end-to-end time from "USDT leaves the sender's wallet abroad" to "fiat arrives in the recipient's wallet in Cambodia" is usually 5-15 minutes.

Thailand, Malaysia, Korea: The Major Remittance Corridors

Cambodia's overseas worker population is concentrated in three destinations. Thailand hosts the largest community by a significant margin — Cambodian workers in construction, agriculture, fisheries and service industries account for hundreds of thousands of cross-border workers. The Thailand-Cambodia border is permeable for daily and seasonal labour movement, and Cambodian workers in Bangkok routinely send money home through informal channels alongside formal ones.

Malaysia is the second-largest corridor. Cambodian workers in Malaysia are typically on multi-year contracts, primarily in plantation work, manufacturing and domestic service. Remittance frequency is monthly rather than weekly. South Korea, through the Employment Permit System, hosts a smaller but higher-wage Cambodian workforce — Korean wages allow larger per-worker remittances despite the smaller population.

Total remittance flow into Cambodia ran approximately $1.5 billion in recent years — about 6% of GDP. This is smaller than Bangladesh or Nepal in absolute terms, but the cost-saving impact of switching from MTOs to USDT is similar per-worker: roughly 3-5 percentage points of fee saving on each transfer, accumulating to meaningful annual amounts.

P2P Conversion: Wing, TrueMoney and Bank Transfer

Once USDT arrives in a recipient's Tron wallet in Cambodia, the conversion to dollars or riels happens through one of several channels. Binance P2P is the dominant formal channel, with approximately 200,000 registered Cambodian users supporting USDT trades against KHR and USD with settlement via Wing, KHQR, and direct bank transfer. Wing is Cambodia's largest mobile money operator and the most common settlement method on small to medium-sized P2P trades. TrueMoney is the second-largest mobile wallet. ABA Pay and ACLEDA Mobile are the bank-side options for direct deposits.

The P2P spread on USDT-to-USD pairs in Cambodia is among the tightest in the region — typically under 1% — because there is minimal currency conversion (USDT is dollar-pegged and dollars are already widely held). USDT-to-KHR spreads are slightly wider at 1-2%, reflecting the additional conversion. Settlement times during business hours are typically 5-15 minutes; outside business hours, longer.

One practical dynamic: because Binance's website was blocked in November 2024 along with 15 other foreign exchanges, many Cambodian users access Binance P2P through the mobile app rather than the web. The mobile app has continued to function. Trust Wallet, OKX Wallet and other non-custodial wallets have also retained access. The blocking is an enforcement signal; it does not currently prevent individual P2P activity.

The 13 TRX Fee and How to Cut It

Every outgoing USDT TRC-20 transfer — whether from a Cambodian worker in Bangkok to family in Battambang, from a P2P counterparty paying out a remittance, or from a freelancer paying for international services — costs approximately 13 TRX in Tron network fees without Energy pre-loaded. At a TRX price of $0.30, that is $3.90 per send. For a Thailand-based worker sending money home twice a month, that compounds to roughly $93 per year in network fees alone.

The fix is Energy delegation through TronNRG: send 4 TRX before each USDT transfer, receive 65,000 Energy in approximately 3 seconds, then send your USDT at a 4 TRX cost instead of 13 TRX. The 9 TRX saved per transfer — roughly $2.70 — stays in the sender's wallet rather than being burned by the Tron network. For P2P counterparties making dozens of payouts daily across Phnom Penh, the saving compounds rapidly.

The New Regulatory Framework: Group 1 and Group 2

Cambodia's crypto regulatory framework changed substantially in late 2024. Prior to that, the position was effectively prohibitive: NBC notices from earlier years had stated that banks and financial institutions could not handle cryptocurrency transactions. In December 2024, the National Bank of Cambodia issued a Prakas on Cryptoassets that introduced a two-tier classification system.

Group 1 cryptoassets include tokenized traditional financial instruments and approved stablecoins, including USDT and USDC. Banks and licensed payment institutions may provide services for Group 1 assets — exchange against fiat currencies, transfer services, and custody — with prior approval from the NBC. Group 2 cryptoassets are unbacked cryptocurrencies including Bitcoin and Ethereum. Institutional handling of Group 2 assets remains prohibited.

The November 2024 telecom regulator action that blocked 16 foreign exchange websites — Binance, Coinbase and others — reflects the ongoing intent to push activity toward licensed onshore channels. Mobile apps and non-custodial wallet activity have not been similarly restricted. The framework is evolving toward tighter institutional control combined with permissive treatment of dollar-pegged stablecoin activity, particularly for cross-border use cases that align with the NBC's broader payment infrastructure goals.

For ordinary users, the practical implication is that USDT activity for personal remittance and dollar value transfer purposes operates in a more permissive space than Bitcoin or Ethereum activity. The framework is more facilitative than the equivalent positions in Algeria or Nepal. But the regulatory direction can shift, and anyone building ongoing activity around the corridor should follow NBC announcements and consult a local adviser.
