Cambodia’s economic history is a dramatic saga of rise, fall, total destruction, and remarkable recovery. From the legendary wealth of the medieval Angkor Empire, which dominated mainland Southeast Asia, to the structural exploitation of the French colonial protectorate, the country’s financial systems have undergone radical transformations. In the late 20th century, Cambodia suffered one of the most extreme economic experiments in human history under the Khmer Rouge regime, which abolished currency, markets, and private property altogether. Following a decade of slow, Vietnamese-backed reconstruction and a transitional period of United Nations stewardship in the 1990s, Cambodia emerged as one of the world's fastest-growing economies, driven by a booming garment manufacturing industry, high levels of dollarization, and, in recent years, massive infrastructure investment linked to China’s Belt and Road Initiative (BRI). Understanding this trajectory is crucial for analyzing Cambodia's modern economic future and the structural forces that shape its contemporary financial landscape.
Between the 9th and 15th centuries, the Angkor Empire (Khmer Empire) stood as a colossal economic power. The foundation of Angkor's wealth was its sophisticated agricultural infrastructure. Through an intricate network of massive reservoirs (barays), canals, and irrigation channels, Khmer engineers successfully mastered the monsoon cycle. This allowed for up to three rice harvests per year, creating an enormous agricultural surplus. This surplus sustained a large urban population, funded the construction of monumental stone temples like Angkor Wat, and supported a standing military force.
Despite the empire's vast size and wealth, its internal economy functioned without a centralized metallic currency. Trade was conducted primarily through a barter system, alongside the use of commodity money such as rice, silk, and silver bullion (measured by weight, or tamlung). Chinese diplomat Zhou Daguan, who visited Angkor in 1296, recorded that small transactions were settled with rice, grain, and Chinese goods, while larger trade involved gold, silver, or luxury fabrics. International trade was robust, with Khmer merchants exporting ivory, cardamom, beeswax, and exotic woods to China and India, while importing porcelain, lacquerware, and metal goods. The lack of standard coinage, however, meant that the domestic economy remained localized and heavily tied to seasonal agricultural cycles, making the empire's wealth highly dependent on the upkeep of its hydraulic infrastructure. When climate instability and administrative decay disrupted the water systems in the 15th century, the economic foundation collapsed, leading to the abandonment of Angkor.
After centuries of regional instability and territorial losses to Siam and Vietnam, Cambodia became a French protectorate in 1863. The French colonial administration sought to integrate Cambodia into a broader Indochinese economic framework. To modernize the fiscal system and fund colonial operations, the French introduced the Indochinese Piastre in 1885, establishing a unified currency across Vietnam, Laos, and Cambodia. This represented Cambodia's first transition to a modern, state-sanctioned monetary economy.
However, French economic policy was extractive and structural. The protectorate introduced heavy head taxes, land taxes, and state monopolies on opium, salt, and alcohol, which placed a severe financial burden on the Khmer peasantry. Infrastructure development was limited and highly selective, focusing on routes that facilitated the extraction of raw materials. The French established massive rubber plantations in eastern Cambodia, particularly in Kampong Cham, using imported Vietnamese labor and local sharecroppers. While these plantations became highly profitable for French concessionaires like Michelin, very little wealth was reinvested into the Cambodian population. The education system was neglected, leaving the country with a tiny administrative elite and a largely illiterate agricultural class. By the time Cambodia achieved independence in 1953, its financial infrastructure was weak, characterized by a lack of domestic industries and a heavy reliance on agricultural exports.
Following independence, Prince Norodom Sihanouk’s government attempted a period of modernization and state-led industrialization. However, the spillover of the Vietnam War and a military coup in 1970 plunged the nation into civil war. In April 1975, the radical agrarian communist Khmer Rouge, led by Pol Pot, captured Phnom Penh and initiated "Year Zero." The regime's goal was the total eradication of capitalism, urban life, and modern institutions in favor of a completely self-reliant, agrarian society.
One of the Khmer Rouge’s first acts was the absolute destruction of the financial sector. The regime systematically dynamited the headquarters of the National Bank of Cambodia in Phnom Penh, burnt paper currency in the streets, and declared the riel (introduced in 1955) completely worthless. Private property, banking systems, markets, and wage labor were completely abolished. The entire urban population was forced into rural labor collectives, where work was coerced through violence and food was rationed by the state. The economy was reduced to a state-controlled barter system, with the government managing all distribution of food and basic supplies. This catastrophic economic experiment, combined with mass executions and starvation, resulted in the deaths of an estimated 1.5 to 2 million Cambodians (nearly a quarter of the population) and the complete annihilation of the country's physical, intellectual, and economic capital.
The overthrow of the Khmer Rouge regime by Vietnamese forces in January 1979 left Cambodia in a state of absolute ruin. There were no functioning government ministries, no banks, no schools, and no legal framework. The newly established People's Republic of Kampuchea (PRK) faced the daunting task of rebuilding an economy from scratch while fighting an active insurgency along the Thai border and facing an international trade embargo led by the United States and China.
In March 1980, the transitional government successfully re-established the National Bank of Cambodia and reintroduced the Cambodian riel. Initially, the government had to distribute the new currency to citizens for free to kickstart transactions and encourage its adoption. Due to a total lack of trust in paper money and memories of the Khmer Rouge era, citizens initially preferred to use gold and rice for trade. Gradually, however, the riel gained acceptance for small-scale local transactions. Throughout the 1980s, Cambodia operated as a command economy under Vietnamese influence, with state-owned enterprises, price controls, and collective farming. State-led reconstruction helped restore basic agricultural production and stabilize the population, but the country remained desperately poor, isolated, and reliant on limited aid from the Soviet Union and Eastern Bloc nations.
The end of the Cold War and the signing of the Paris Peace Accords in 1991 marked a major turning point. In 1992, the United Nations Transitional Authority in Cambodia (UNTAC) arrived to oversee democratic elections, demobilize armed factions, and manage the transition to a market economy. UNTAC represented one of the largest and most expensive peacekeeping operations in UN history, injecting approximately $1.7 billion into the Cambodian economy.
This massive influx of capital was almost entirely in US dollars. Because the local banking system was practically non-existent and the riel was highly volatile, the US dollar quickly became the de facto currency for real estate, business transactions, and consumer spending. This marked the beginning of Cambodia's deep, structural dollarization, which persists to this day. Following the 1993 elections, which established the constitutional monarchy, the government embraced economic liberalization. Foreign investment laws were relaxed, state assets were privatized, and trade barriers were dismantled. Dollarization provided immediate macroeconomic stability, eliminating hyperinflation and attracting foreign investors who faced no currency exchange risks. However, it also severely limited the central bank's ability to conduct independent monetary policy.
By the mid-1990s, Cambodia found its primary economic engine: garment manufacturing. Capitalizing on its low labor costs and favorable trade agreements with Western nations, Cambodia became a major hub for apparel exports. Under the Multi-Fiber Arrangement (MFA) and subsequent trade privileges like the European Union's "Everything But Arms" (EBA) scheme and the US Generalized System of Preferences (GSP), Cambodia enjoyed duty-free and quota-free access to major Western markets.
The sector grew exponentially, attracting substantial foreign direct investment (FDI) from Taiwan, Hong Kong, China, and South Korea. By the 2010s, garment, footwear, and travel goods exports accounted for over 70% of Cambodia's total merchandise exports, employing over 800,000 workers, predominantly young women from rural provinces. The wages sent back by these workers to their home villages transformed rural livelihoods and acted as a major domestic poverty reduction tool. This structural transition from agriculture to low-skill manufacturing fueled an average annual GDP growth rate of over 7.7% between 1998 and 2019, making Cambodia one of the fastest-growing economies in the world.
Over the last fifteen years, Cambodia’s economic partnership has shifted heavily toward Beijing. As Western nations increasingly conditioned aid and trade preferences on human rights and democratic reforms, Cambodia's leadership turned to China as an alternative source of capital. Under the umbrella of China's Belt and Road Initiative (BRI), Cambodia has received billions of dollars in Chinese loans, grants, and FDI.
This capital has financed a massive infrastructure boom, including thousands of kilometers of paved highways, major bridges, deep-water ports, and massive hydropower dams that have lowered electricity costs across the country. A prominent symbol of this era is Sihanoukville, which transformed from a sleepy coastal town into a sprawling enclave of Chinese-run casinos, high-rise real estate, and Special Economic Zones. While this infrastructure investment has addressed critical developmental bottlenecks, it has also led to concerns over rising external debt, economic sovereignty, and high dependency on a single foreign patron.
As Cambodia's financial sector matured, rebuilding the central bank became a primary national priority. Today, the National Bank of Cambodia (NBC) has evolved into a highly professional regulatory institution, despite operating in a highly dollarized environment where over 80% of bank deposits are denominated in US dollars. The NBC's primary tools for maintaining macroeconomic stability include managing the exchange rate of the riel to the dollar and enforcing high reserve requirements.
To modernise the financial ecosystem and encourage the use of the local currency, the NBC launched Project Bakong in 2020. Bakong is a blockchain-based, central-bank-backed digital payment system designed to facilitate peer-to-peer transfers, improve financial inclusion for unbanked citizens, and reduce transaction costs. The system has seen rapid adoption, connecting millions of users and local merchants. Through Bakong and other regulatory policies, the NBC aims to gradually de-dollarize the economy, promoting the riel as the primary medium of exchange to reclaim monetary sovereignty.
One of the most controversial aspects of Cambodia’s modern financial landscape is the rapid expansion of its microfinance sector. In the early 2000s, Microfinance Institutions (MFIs) were hailed as a powerful tool for poverty alleviation, providing small, unsecured loans to rural households to start businesses or purchase agricultural equipment. However, the sector quickly commercialized, attracting foreign commercial banks and private equity.
By the 2020s, Cambodia had one of the highest levels of microfinance debt per capita in the world. Many rural households, facing stagnant agricultural yields, borrowed to repay existing debts, build homes, or purchase consumer goods. Because many MFI loans in Cambodia require land titles as collateral, the rapid expansion of credit has led to high rates of over-indebtedness, forced land sales, and human rights concerns. Despite efforts by the NBC to impose interest rate caps (capped at 18% in 2017) and strengthen consumer protection, the microfinance sector remains a significant risk to the country's financial stability and social cohesion.
From the non-monetary, agricultural prosperity of Angkor to the extreme destitution of the Khmer Rouge regime, Cambodia's financial history is defined by structural adaptation and resilience. The modern Cambodian economy has made extraordinary strides, lifting millions of citizens out of poverty and building a sophisticated financial system from scratch. However, the legacy of conflict and rapid development has left deep structural challenges. Managing a dual-currency system, navigating high levels of household debt, and maintaining a balanced foreign policy amidst heavy Chinese investment are critical hurdles. As Cambodia aims to graduate from Least Developed Country (LDC) status and modernize its financial architecture, the lessons of its complex history will continue to shape its developmental path. For a deeper understanding of how these historical patterns influence modern defense and strategic decisions, see the role of the Royal Cambodian Armed Forces and Cambodian defense spending in national development, as well as the broader Cambodian fiscal management systems that govern the state.
