From the 1962 KCIA Stock Crash to South Korea’s Three Lows KOSPI Boom

When the Daehan Stock Exchange opened in Seoul’s Myeong-dong financial district on March 3, 1956, South Korea possessed virtually no modern equity culture. Devastated by the 1950–1953 Korean War, the country’s fledgling trading floor listed just a dozen state-vested companies and functioned overwhelmingly as a secondary discount market for government war-reconstruction bonds. Yet within six years, that sleepy bond bourse became the epicenter of the first great financial scandal of South Korea’s military era: the May 1962 Stock Market Crisis (Jeonggwon Padong). ^[1]

In early 1962, operatives of the newly established Korean Central Intelligence Agency (KCIA) covertly teamed up with speculative brokerage syndicates to corner the stock market and extract secret political funds for Major General Park Chung-hee’s ruling junta. Share prices of the exchange’s own stock multiplied more than a hundredfold before a catastrophic clearing failure at the end of May 1962 bankrupted or paralyzed all 56 brokerage firms, wiped out thousands of retail investors, and forced the exchange to shut down. Overcoming the trauma of 1962 required two decades of coercive state intervention—most notably the 1968 Capital Market Promotion Act and the 1972 Public Corporation Inducement Act forcing reluctant chaebol families to go public—which ultimately built the institutional foundation for the 1986–1989 “Three Lows” (Samjeo) export boom that drove the benchmark KOSPI index from 160 to 1,007. ^[2]

The March 1956 Founding of the Daehan Stock Exchange#

During the Japanese colonial period, equity trading on the peninsula had been conducted under the 1943 Joseon Stock Exchange Ordinance, which was suspended by the U.S. Army Military Government in 1946. During and immediately after the Korean War, President Syngman Rhee’s administration issued vast quantities of National Founding Bonds (Geonguk Gukchae) to finance wartime expenditures and Farmland Compensation Bonds (Jiga Jeonggwon) to compensate landlords dispossessed by land reform. Because inflation was rampant and commercial bank credit was scarce, bondholders routinely sold these government notes at steep discounts in informal curb markets around Myeong-dong. ^[3]

To formalize trading and channel private savings into post-war reconstruction, five leading securities firms founded the Korea Securities Dealers Association in November 1953 and petitioned the Ministry of Finance to establish an official exchange. Jointly capitalized by commercial banks, insurance companies, and securities brokers, the Daehan Stock Exchange (Daehan Securities Exchange) officially opened in Myeong-dong on March 3, 1956. ^[4]

In its early years, the exchange was an equity market in name only. Only 12 to 15 corporations—chiefly former Japanese colonial enterprises vested in the state, such as Chosen Stock Exchange successor entities, commercial banks, Korea Electric Power, and shipping and spinning companies—were listed on the board. Trading relied on manual open outcry and chalkboard tallies. Because family-owned businesses feared losing managerial control or exposing their books to tax collectors, private initial public offerings were nonexistent. In both 1957 and 1960, government bonds accounted for 83 percent of total trading value on the Daehan Stock Exchange, while corporate equities represented just 17 percent. ^[5]

Park Chung-hee’s Junta and the January 1962 Securities Act#

The character of the Seoul market changed abruptly after Major General Park Chung-hee seized power in the May 16, 1961 military coup. Seeking to legitimize its rule through rapid industrialization, the junta—formally styled the Supreme Council for National Reconstruction—unveiled South Korea’s First Five-Year Economic Development Plan (1962–1966), targeting an ambitious 7.1 percent annual GDP growth rate. Of the plan’s total projected investment of 321.5 billion won (3.215 trillion hwan prior to the June 1962 currency conversion), the junta projected that 232.6 billion won—or 72 percent—had to be mobilized from domestic capital (naeja). ^[6]

To force idle domestic cash into industrial equity, the junta enacted the National Savings Act in February 1962 and, on January 15, 1962, promulgated the foundational Securities and Exchange Act (Law No. 972), repealing the colonial-era 1943 ordinance. Taking effect on April 1, 1962, the new law converted the Daehan Stock Exchange from a non-profit public membership organization into a commercial joint-stock corporation (jusikhoesa). Critically, this restructuring allowed the exchange to issue its own capital contribution certificates—popularly known as “exchange shares” (daejeungju)—which traded directly on the exchange floor alongside the 15 other listed stocks. ^[7]

At the same time, the exchange operated under a highly leveraged “clearing transaction” (cheongsan georae) futures system. Rather than settling trades in cash within days, buyers and sellers could trade on thin margins and defer settlement until the end of the month, with the Daehan Stock Exchange itself legally guaranteeing final delivery and payment.

KCIA Manipulation and the May 1962 Stock Market Crisis#

Behind the scenes of the junta’s capital-market push lay an urgent political imperative. Park Chung-hee had promised the Kennedy administration that the military would transfer power to an elected civilian government in 1963. To ensure that Park and his military allies won that election, Park’s nephew-by-marriage and first director of the Korean Central Intelligence Agency (KCIA), Kim Jong-pil, quietly began organizing what would become the ruling Democratic Republican Party (DRP). Building a nationwide party apparatus required immense off-budget financing. ^[8]

In early 1962, KCIA operatives entered the stock market to engineer a speculative boom that could both showcase economic vitality and generate clandestine political slush funds—one of the regime’s infamous “Four Major Scandals” alongside the Walkerhill Hotel project, Saenara Motors duty-free car imports, and imported slot machines. Working through aggressive market operator Yun Eung-sang and a syndicate of newly licensed brokerage houses (including Nonglim and Tongil Securities), KCIA-backed buyers cornered shares of the Daehan Stock Exchange itself (daejeungju) and state-backed Korea Electric Power (KEPCO), while instructing state-controlled commercial banks and the central bank to extend generous credit to the bullish faction.

With only 14 to 16 stocks listed on the entire exchange, the liquidity injection ignited a manic speculative frenzy. Equities jumped from 17 percent of exchange turnover in 1960 to 99 percent in 1962, and daejeungju alone accounted for 68 percent of all stock trading. The price of a Daehan Stock Exchange share soared more than 130-fold, climbing from 0.031 won (in post-June 1962 unit terms) in July 1961 to 0.92 won in March 1962 and 4.25 won in April 1962. Total monthly trading volume on the exchange exploded nearly thirty-fold inside three months, rising from 885.4 million won in February 1962 to 3.425 billion won in March, 11.845 billion won in April, and 25.21 billion won in May 1962.

As share prices reached absurd valuations, U.S. Embassy officials in Seoul—who later estimated in declassified State Department briefings to President John F. Kennedy that Kim Jong-pil’s KCIA network extracted between $20 million and $30 million in illicit profits from the market manipulation—warned the junta against inflationary bank lending, while the KCIA-linked syndicate quietly unloaded its peak holdings onto euphoric retail speculators and rival brokers.

The reckoning arrived on May 31, 1962—the monthly settlement deadline for May clearing transactions. Having bought massive volumes of overpriced stock on margin while KCIA insiders cashed out, the bullish brokerage syndicates could not pay for their May deliveries, leaving an unpaid settlement deficit of roughly 12.9 billion hwan (1.29 billion won). Because the Daehan Stock Exchange lacked the capital reserves to honor its clearing guarantee, the entire settlement chain collapsed.

Across Seoul, all 56 registered securities companies defaulted on their clearing obligations or fell into acute insolvency. Panic swept Myeong-dong as ruined middle-class investors besieged brokerage offices and several speculators took their own lives. Ten days later, on June 9, 1962, the military junta compounded the paralysis by launching an abrupt overnight currency reform that replaced the hwan with the won at a 10-to-1 ratio and froze bank deposits, draining whatever liquidity remained in the financial system. Although the government ordered emergency commercial bank loans to clear a fraction of the defaulted contracts, repeated crashes forced the Ministry of Finance to shut down the exchange in early 1963. In April and May 1963, the government amended the Securities and Exchange Act to abolish the joint-stock exchange structure, reorganized the market back into a state-controlled public corporation renamed the Korea Stock Exchange (KSE), and forced Kim Jong-pil into temporary political exile abroad.

Forcing the Chaebol Public: The 1968 and 1972 Acts#

The May 1962 crisis left deep scars on South Korean household savers, who shunned equities as a rigged casino and returned their cash to high-interest informal curb markets (sache). When the government doubled commercial bank deposit rates in the September 1965 interest-rate reform, stock trading shriveled further. Yet by the late 1960s, South Korea’s rapidly expanding industrial conglomerates (chaebol) were dangerously over-leveraged with short-term bank and foreign loans, while founding families stubbornly refused to dilute their equity ownership through public listings.

Determined to build a functioning equity market, President Park Chung-hee’s administration shifted from laissez-faire speculation to statutory compulsion. In November 1968, the National Assembly enacted the Capital Market Promotion Act (Law No. 2046). Pioneered by Finance Ministry officials and future Korea Stock Exchange chief Kim Yong-wan, the 1968 law granted substantial corporate tax reductions to publicly listed companies, guaranteed minimum dividend yields to small retail shareholders of state enterprises, and established the state-backed Korea Investment Corporation (KIC) to underwrite share offerings and stabilize prices.

When family-owned chaebol still hesitated—adding only a few dozen listings over four years—Park Chung-hee followed his August 3, 1972 emergency curb-market freeze with the December 30, 1972 Public Corporation Inducement Act (Gi-eop Gong-gae Chok-jin-beop). One of the most coercive securities laws in modern financial history, the 1972 Act empowered the Minister of Finance to screen private corporations by capital size, profitability, and debt ratio and issue formal government orders compelling designated chaebol subsidiaries to list at least 30 percent of their shares on the Korea Stock Exchange. Any conglomerate that defied a listing order faced higher corporate tax rates, limits on tax deductions, and immediate restriction of commercial bank credit from Korea’s state-owned banking system.

The statutory stick worked immediately. In 1973 alone, dozens of major industrial firms went public, pushing the number of listed companies on the Korea Stock Exchange past 100 for the first time, and reaching 356 listed corporations by 1979. In February 1977, the government further modernized oversight by establishing the Securities and Exchange Commission and the Securities Supervisory Board.

The 1986–1989 “Three Lows” Boom and KOSPI 1,000#

By the early 1980s, South Korea possessed both a broad roster of listed industrial companies and a modernized market benchmark: on January 4, 1983, the Korea Stock Exchange replaced its old price-average indicator with the capitalization-weighted Korea Composite Stock Price Index (KOSPI), calibrated to a base value of 100 as of January 4, 1980.

Beginning in late 1985, the global macroeconomic environment aligned in South Korea’s favor through a phenomenon Koreans called the “Three Lows” (Samjeo): low international crude oil prices (which fell below $15 per barrel in 1986), low international interest rates (which slashed the servicing cost of South Korea’s external debt), and a low US dollar—and consequently a cheap Korean won—relative to the Japanese yen after the September 1985 Plaza Accord doubled the yen’s value. Suddenly, South Korean automobiles, semiconductors, electronics, ships, and steel enjoyed an immense price advantage over Japanese rivals in North American and European markets.

Between 1986 and 1988, South Korea’s real GDP grew by more than 12 percent annually, and the country’s chronic trade deficits flipped into record current-account surpluses peaking at $14.2 billion in 1988. Flush with export liquidity and buoyed by national pride surrounding the 1988 Seoul Summer Olympics and the government’s listing of “people’s shares” (gungminju) in state giants POSCO and Korea Electric Power, millions of ordinary Korean households returned to the stock market for the first time since the 1962 crash.

From 163.37 points at the end of 1985, the KOSPI surged more than sixfold inside three years—crossing 500 in 1987, 900 in late 1988, and breaking the historic 1,000-point barrier in late March 1989 before reaching a peak close of 1,007.77 on April 1, 1989. Total market capitalization surpassed 95 trillion won, and the number of listed companies topped 600, completing the thirty-three-year transformation of the Daehan Stock Exchange from a war-bond curb market and intelligence-agency slush fund into one of Asia’s premier industrial capital markets.
