On January 26, 2017, the cryptocurrency world was watching Beijing. The People’s Bank of China (PBOC) had launched an unprecedented regulatory offensive against the country’s largest Bitcoin exchanges, fundamentally altering the landscape of digital currency trading in the world’s most active crypto market. The consequences would ripple across the global cryptocurrency ecosystem for months to come.
TL;DR
- PBOC inspected BTCC, Huobi, and OKCoin — China’s three largest Bitcoin exchanges
- All three exchanges introduced trading fees around January 24, ending zero-fee trading
- Margin trading was banned, and AML/KYC requirements were significantly strengthened
- Joint inspection teams focused on payment settlement, foreign currency management, and financial security
- Nine Chinese exchanges summoned to a closed-door meeting with regulators
The Inspections Begin
The regulatory pressure began in earnest on January 5, when the PBOC summoned representatives from major Bitcoin exchanges to remind them that Bitcoin was not recognized as a currency under Chinese law. What followed was a rapid escalation. By January 11, the PBOC Shanghai branch, working alongside the Shanghai Municipal Finance Office, launched on-site inspections of BTCC — one of the world’s oldest and most prominent Bitcoin exchanges.
The inspections quickly expanded to include Huobi and OKCoin, the other two giants of Chinese crypto trading. OKCoin addressed the situation directly in a customer service email, stating that authorities were conducting a one-week inspection “only to understand the situation here” with the purpose of maintaining financial stability and regulating market trading behavior. BTCC struck a similarly measured tone, tweeting: “All good, just inspections.”
Zero-Fee Trading Comes to an End
Perhaps the most significant immediate change was the end of zero-fee trading on Chinese exchanges. For years, BTCC, Huobi, and OKCoin had operated without charging trading fees, a practice that had made them extraordinarily popular and contributed to enormous trading volumes. Fortune magazine reported on January 26 that Chinese exchanges had claimed to process nine out of ten global Bitcoin trades — a staggering concentration of market activity driven in large part by the absence of fees.
By January 24, all three major exchanges had introduced trading fees. BTCC had tweeted on January 20 that it was “reviewing the operating experience of foreign counterparts and the charging of transaction fees, aiming to further curb speculation and prevent violent price fluctuation.” OKCoin announced similar measures. A fourth exchange, Yunbi, followed suit shortly thereafter.
The Scope of Regulatory Scrutiny
The PBOC did not limit its intervention to trading fees. A formal statement from the central bank revealed the breadth of its concerns. The PBOC Department of Business Management, Beijing Municipal Bureau of Finance, Municipal Bureau of Industry and Commerce, and other relevant departments formed a joint inspection group that entered Huobi, OKCoin, and other exchanges for on-site reviews.
According to the PBOC statement, the inspection focused on several critical areas: payment settlement practices, anti-money laundering compliance, foreign currency management, and information and financial security. The inspection group specifically warned investors to pay attention to legal compliance, market volatility, financial security, and other risks associated with Bitcoin exchanges.
The Closed-Door Meeting and Its Aftermath
The PBOC then escalated further by inviting nine Chinese Bitcoin exchanges to a closed-door meeting. In addition to the big three — BTCC, Huobi, and OKCoin — smaller platforms including CHBTC, BTCTrade, HaoBTC, and Yunbi were summoned. The message was clear: no margin trading, strict compliance with anti-money laundering laws, and full implementation of know-your-customer procedures.
The exchanges responded quickly. All three major platforms announced they would strengthen their AML and KYC procedures. The CnLedger Twitter account, a respected China-based crypto news source, reported: “BTCC, OKCoin, Huobi: will upgrade AML system according to laws and regulations, pausing BTC LTC withdraw during the upgrade. Estimated time: 1 month.” The withdrawal freeze would prove to be one of the most significant short-term consequences of the crackdown.
The Bigger Picture: Digital Currency Research
In a move that signaled China’s nuanced approach to blockchain technology, the PBOC announced as the Lunar New Year approached that it would establish its own digital currency research institute. The initiative underscored a key distinction in Beijing’s thinking: while private cryptocurrencies faced tightening regulation, the underlying blockchain technology — and the concept of a government-issued digital currency — was being actively explored and embraced.
Why This Matters
The January 2017 PBOC crackdown was a watershed moment for cryptocurrency regulation worldwide. It demonstrated that governments could and would intervene in crypto markets, and that the largely unregulated early days of digital currency trading were coming to an end. The introduction of trading fees on Chinese exchanges fundamentally changed global volume patterns and reduced the influence of wash trading and artificial volume inflation. For the broader market, the events of January 2017 served as an early warning: regulatory risk was real, and compliance would become a permanent feature of the cryptocurrency landscape. The PBOC’s actions also foreshadowed China’s more dramatic interventions later in 2017, including the eventual ban on ICOs and cryptocurrency exchanges that would reshape the global mining and trading industry.
