China’s gold yuan is the rare hyperinflation that was itself a hyperinflation cure — and one that failed faster than the disease it was meant to treat. By the summer of 1948 the Nationalist government’s existing currency, the fabi, had been printed into ruin by a decade of war: first the war against Japan (1937–45), then the civil war against the Communists. On 19 August 1948 the government of Chiang Kai-shek scrapped the fabi and issued the gold yuan at 3 million fabi to one, paired with price controls and a confiscation order requiring citizens to surrender their gold, silver, and foreign currency in exchange for the new notes. Within ten months the gold yuan had collapsed; in Shanghai, wholesale-price inflation peaked at roughly 5,070 percent per month in April 1949, by the Hanke-Krus measure, and the largest note in general issue read one million gold yuan. After the Communist victory the currency was superseded by the renminbi of the new People’s Bank of China, with the gold yuan converted out at 100,000 to one.
The mechanism that destroyed the fabi was straightforward war finance. The Nationalist state could not tax enough to fund its armies through eight years against Japan and the civil war that followed, so it covered the deficit by printing. The “gold yuan” reform did nothing to change that — despite its name it was not backed by gold — and so it inherited the same engine of deficit monetization while adding a fresh injury. The confiscation clause compelled ordinary Chinese to hand over their real wealth, their gold and silver and foreign exchange, for paper that the government then proceeded to print into worthlessness. Those who complied were ruined; those who hoarded their metal were spared.
The reform’s brief, brutal arc is best remembered through its enforcement. In Shanghai the operation was driven by Chiang Ching-kuo, the Generalissimo’s son, in a high-pressure campaign — the “tiger-beating” drive — that arrested speculators and hoarders to prop up confidence in the new money. It held for a matter of weeks. By late 1948 the price controls broke, goods vanished from shelves, and the gold yuan began the same vertical descent the fabi had taken. The new notes climbed through the thousands, ten-thousands, and hundred-thousands within months of issue.
By the time the People’s Liberation Army took the great cities in 1949, the gold yuan was finished as money. The People’s Bank of China, founded on 1 December 1948 and already issuing the renminbi across liberated areas, retired the gold yuan and unified the country’s chaotic currencies under the new unit — the money that anchors China to this day.
The “Mickey Mouse” peso — the fiat currency the Japanese occupation government issued in the Philippines from 1942 — was destroyed by unbacked over-printing and a wartime counterfeit flood, and it was retired by repudiation: on liberation in 1944–45 the notes were declared worthless and never redeemed. Unlike the great hyperinflations of self-financing treasuries, this was the money of a conqueror. After invading in December 1941 and seizing Manila in January 1942, Japan confiscated hard currency, suppressed the prewar Commonwealth peso, and replaced it with military scrip — notes that promised to pay the bearer but were backed by no gold, no silver, and no reserves of any kind. They were money only for as long as the bayonets behind them held the islands.
The over-issue was relentless, and so was the inflation. As the occupation’s costs mounted and the war turned against Japan, the authorities printed without restraint, and prices ran away: by late 1943 monthly inflation in the Philippines was running above 40%, reaching roughly 60% in early 1945. Filipinos nicknamed the notes “Mickey Mouse money” for their cartoonish worthlessness, and the artifacts of the collapse are vivid — by one wartime account 75 occupation pesos (about 35 US dollars at the time) bought a single duck egg, and in 1944 a box of matches cost more than 100 of them. The Japanese chased the spiral with ever-larger denominations, issuing 100- and 500-peso notes in 1944 and topping out at a 1,000-peso note by war’s end; in one four-week stretch in February 1945 they flooded in some 1.3 billion pesos of new currency.
The collapse was hastened by a second printing press the occupiers did not control. The United States, through the Office of Strategic Services, counterfeited the invasion notes en masse — supplying Filipino guerrillas, funding resistance, and deliberately debasing the occupation economy. Genuine and forged notes circulated indistinguishably, and the currency’s credibility, never strong, dissolved entirely.
The verdict was a decree, not a reform. As American and Filipino forces retook the islands in 1944–45, the restored Commonwealth government and the returning authorities repudiated the Japanese-issued peso: it ceased to be legal money, was never exchanged for the restored currency, and tons of it were burned. Holders left with nothing but suitcases of scrip received no redemption — the money died with the regime that issued it.
The old Taiwan dollar died on 15 June 1949, replaced by the New Taiwan dollar at the deliberately punishing rate of forty thousand old to one, as the Chinese Nationalist government lost the mainland and fell back on the island it had ruled for only four years. The old dollar was not destroyed by a war fought on Taiwan; it was wrecked by the war’s financial backwash — the collapse of the mainland’s gold yuan, the cost of arming and feeding a retreating army, and the simple fact that an island currency could not insulate itself from the disintegrating finances of the regime that issued it.
The old Taiwan dollar had circulated only since 1946, issued by the Bank of Taiwan after the island passed from Japanese to Chinese rule at the end of the Second World War. Two pressures then bore down on it. The first was inherited: the Japanese colonial administration had over-issued notes to fund its war effort, leaving a monetary overhang that exploded once wartime price controls lapsed. The second was imported: on the mainland, the Nationalists were financing the civil war against the Communists by printing the fabi and then, after the catastrophic August 1948 “gold yuan” reform, printing that too into worthlessness. Kuomintang military spending and budget deficits drained Taiwan’s resources into the mainland war, and the island’s prices soared.
By 1948 the Bank of Taiwan was printing 10,000-dollar notes and issuing bearer’s cheques denominated at one million Taiwan dollars; at the height of the inflation a kilogram of rice cost around 1.6 million old dollars and a single duck egg some 5,000. The old dollar fell faster the closer the mainland came to total Nationalist defeat, which arrived with the Communist victory and the Nationalist evacuation in December 1949.
The reform that retired it was engineered for credibility. The New Taiwan dollar, launched on 15 June 1949 by the Taiwan Provincial Government, was backed by gold and silver that Chiang Kai-shek’s government had shipped from the mainland — reported at some 800,000 taels of gold plus US$10 million and over ten million silver dollars — and its issuance was capped at NT$200 million. Provincial governor Chen Cheng made the new notes convertible into physical gold. The peg and the reserve, reinforced by American aid after the Korean War broke out in 1950, held the New Taiwan dollar, which remains Taiwan’s currency to this day.
The đồng of the Republic of Vietnam — the money of the South — did not die of a textbook hyperinflation. It was abolished by the government that won the war. When North Vietnamese forces took Saigon on 30 April 1975, the currency of the defeated republic was a marked unit, and on 22 September 1975 the new authorities replaced it by decree with a “liberation đồng” at 500 old Southern đồng to 1. Three years later, on 3 May 1978, when the two halves of the country were given a single currency, the South was made to pay again: one new unified đồng was worth one Northern đồng but only 0.8 of a Southern liberation đồng. The old money of the South had ceased to be money, and the savings denominated in it were gone.
The South Vietnamese đồng had real weaknesses before the end. The Republic financed a long war against a determined insurgency, leaning heavily on American aid; when that aid was cut after the 1973 Paris Peace Accords, the budget gap was covered by the printing press, and inflation ran at roughly 44.5% in 1973, with sharp economic contraction through 1974 and 1975. But high wartime inflation is not what retired the currency. What retired it was conquest. The instrument of erasure was not a runaway money supply but a pair of administrative conversions — capped, one-time, and irreversible — imposed on a defeated population.
The mechanism was deliberate. The 22 September 1975 conversion did not simply restate prices in a new unit; it was a tool of social transformation. Households were required to surrender their cash and exchange it at the punitive 500:1 rate, with the amount any family could convert subject to ceilings; balances above the line, and the bank accounts of the old regime, were frozen or confiscated outright. Cash that could not be exchanged was worthless paper. A merchant’s working capital, a clerk’s lifetime of saving, a widow’s banknotes under the floorboards — all were reduced, at a stroke, to whatever the authorities permitted to pass through the conversion window.
This is therefore a case of repudiation, not reform. A reform stabilizes a currency people still hold; this act extinguished the holdings of the people who held it. The South Vietnamese đồng was not redenominated to make arithmetic easier or stabilized to restore trust. It was abolished as an attribute of a state that no longer existed, and the wealth stored in it was treated as a spoil of the victory. The losers were ordinary Southerners, and their losses were the point.
