In 1921, Sinkiang (Xinjiang) Province existed in a state of monetary fragmentation and instability, characteristic of the wider Chinese warlord era. The province was under the de facto autonomous rule of Governor Yang Zengxin, who maintained a fragile balance between the Republic of China's nominal sovereignty and his own practical control. The currency system reflected this political reality, consisting of a chaotic mix of legacy currencies, local issues, and foreign imports. The primary medium was the
Xinjiang Tael (
yinliao), a silver-based unit used for large transactions and official accounts, but the actual physical currency in circulation was a diverse array of silver coins (including Mexican and old Imperial Chinese dollars), copper
cash coins, and most notably, paper notes issued by Yang's provincial government.
These locally printed paper notes, denominated in
taels,
yuan, and
jiang piao (新疆紙鈔), were the workhorse of the everyday economy but suffered from severe depreciation and regional inconsistency. Yang Zengxin issued currency to finance provincial expenditures without sufficient metallic backing, leading to inflation and a deep distrust of paper money among the populace, particularly outside the capital of Dihua (Ürümqi). Furthermore, the vast geography and poor integration of Sinkiang's oases meant that notes issued in one district often traded at a steep discount in another, hampering trade. The situation was exacerbated by the province's economic isolation and the disruption of traditional Silk Road trade.
Compounding the complexity was the influence of foreign currencies along the borders. Russian
Tsarist rubles and, following the Bolshevik Revolution,
Soviet rubles circulated heavily in the Ili and northern regions due to cross-border trade. In the south, Indian rupees and British trade dollars had some presence. This multi-currency environment, with its competing paper issues and varying metallic values, created a landscape ripe for arbitrage and merchant speculation. Ultimately, the monetary chaos of 1921 Sinkiang was a direct manifestation of its political separation from central China, its ruler's fiscal policies, and its position as a contested economic crossroads of Inner Asia.
