In economics, hyperinflation is a very high and typically accelerating inflation. It quickly erodes the real value of the local currency, as the prices of all goods increase. This causes people to minimize their holdings in that currency as they usually switch to more stable foreign currencies. When measured in stable foreign currencies, prices typically remain stable. Effective capital controls and currency substitution (“dollarization”) are the orthodox solutions to ending short-term hyperinflation; however there are significant social and economic costs to these policies. Ineffective implementations of these solutions often exacerbate the situation. Many governments choose to attempt to solve structural issues without resorting to those solutions, with the goal of bringing inflation down slowly while minimizing social costs of further economic shocks.

Japanese military currency was money issued to the soldiers of the Imperial Japanese Armed Forces as a salary. The military yen reached its peak during the Pacific War period, when the Japanese government excessively issued it to all of its occupied territories. In Hong Kong, the military yen was forced upon the local population as the sole official currency of the territory. Since the military yen was not backed by gold, and did not have a specific place of issuance, the military yen could not be exchanged for the Japanese yen. Forcing local populations to use the military yen officially was one of the ways the Japanese government could dominate the local economies.

After the fall of the Qing dynasty in 1912, China underwent a period of instability and disrupted economic activity. During the Nanjing decade (1927–1937), China advanced in a number of industrial sectors, in particular those related to the military, in an effort to catch up with the west and prepare for war with Japan. The Second Sino-Japanese War (1937–1945) and the following Chinese civil war caused the retreat of the Republic of China and formation of the People's Republic of China.
The paper money of the Qing dynasty was periodically used alongside a bimetallic coinage system of copper-alloy cash coins and silver sycees; paper money was used during different periods of Chinese history under the Qing dynasty, having acquired experiences from the prior Song, Jin, Yuan, and Ming dynasties which adopted paper money but where uncontrolled printing led to hyperinflation. During the youngest days of the Qing dynasty paper money was used but this was quickly abolished as the government sought not to repeat history for a fourth time; however, under the reign of the Xianfeng Emperor, due to several large wars and rebellions, the Qing government was forced to issue paper money again.
The banknotes of the Ta-Ching Government Bank, known as the banknotes of the Ta-Ching Bank of the Ministry of Revenue from 1905 to 1908, were intended to become the main form of paper money in the Qing currency system.

The Ta-Ching Government Bank had branches throughout China and many of its branches outside of its headquarters in Beijing also issued banknotes.
The Chinese gold yuan was a legal tender currency of China between August 1948 and 1949. It was a method used by the Republic of China government to accumulate gold from its citizens in preparation to relocate to Taiwan. It circulated in the country under the effective control of the Government of the Republic of China known as Taiwan Province, R.O.C., which issued paper money on August 19, 1948. This currency was notorious for vicious inflation due to inadequate issuance preparation and failure to strictly enforce issuance limits. In the early days of the issuance of the Golden yuan, the government used executive actions to force the public to exchange gold, foreign currency for the new currency. The legal exchange rate was 0.22217 grams of gold per gold yuan but it could not be honored. The sharply depreciating Fabi currency was at the rate of one golden yuan of the yen to Fabi $3 million, and this rate was used for the compulsory collection of public gold, silver, and foreign currency. In particular, the economic losses suffered by the urban middle class were so great that the ROC government lost its original most important supporters and was one of the reasons why the ROC government failed so quickly in the Chinese Civil War.
