The Japanese financial landscape for cryptocurrency trading may be on the brink of a transformative shift. Recent discussions at the Financial Services Agency (FSA)’s seventh "Cryptocurrency Exchange Workshop" have signaled a potential crackdown on high-leverage margin trading, with regulators proposing a dramatic reduction in allowable leverage—possibly down to just 2x. This move, inspired by European regulatory models, could significantly reshape how Japanese investors engage with crypto derivatives.
As digital asset adoption grows globally, Japan is re-evaluating its approach to investor protection, market stability, and financial oversight in the volatile world of cryptocurrency derivatives. The proposed regulations aim not to ban crypto trading, but to ensure it operates within a safer, more transparent framework.
Understanding Crypto Derivatives and Margin Trading
Before diving into the regulatory implications, it’s essential to clarify what crypto derivatives trading and crypto margin trading actually mean in this context.
What Are Crypto Derivatives?
Crypto derivatives are financial instruments whose value is derived from an underlying asset—in this case, cryptocurrencies like Bitcoin or Ethereum. These include:
- Futures contracts
- Options
- Margin trading (leveraged trading)
In margin trading, users deposit collateral (fiat or crypto) to borrow funds and increase their trading position size. For example, with 5x leverage, a $1,000 deposit can control a $5,000 position. While this amplifies potential gains, it also increases the risk of liquidation during sharp price swings.

Credit Trading vs. Derivatives: Similar Risks
The FSA also examined crypto credit trading, where users borrow digital assets directly from exchanges to sell high and buy back low (short selling). Despite structural differences, both credit and derivatives trading involve leverage, counterparty risk, and volatility exposure, leading regulators to consider them functionally equivalent in terms of risk profile.
Thus, if derivatives fall under financial regulation, so too should credit trading—ensuring consistent oversight across leveraged crypto products.
Current State of Leverage in Japan’s Crypto Market
As of now, seven out of 16 registered crypto exchanges in Japan offer margin trading services, while only two support credit trading. Despite the relatively small number of dedicated derivative traders—around 142,000 out of 3 million total users—derivatives dominate trading volume.
Shockingly, over 80% of Japan’s total crypto trading volume in 2017 came from derivatives, amounting to $54.3 billion annually, with 90% of that driven by margin trading. This highlights a critical disconnect: a minority of users generate the majority of market activity through high-risk strategies.
Yet, due to the absence of formal regulation under Japan’s Financial Instruments and Exchange Act (FIEA), there are no standardized limits on leverage or mandatory stop-loss mechanisms. As a result, traders face real risks when markets crash:
- System outages prevent timely liquidations
- Users cannot close positions during volatility spikes
- Investor complaints about losses have surged
These issues have prompted the FSA to act—not because crypto itself is deemed unsafe, but because unregulated leverage poses systemic risks to retail investors.
Should Crypto Derivatives Be Regulated?
The central question before the FSA workshop was whether crypto-based derivatives should be classified as financial instruments subject to regulation. Two key criteria were considered:
- Does the transaction serve a financial function?
- Is there public demand for regulatory oversight given societal impact and speculative risks?
Derivatives inherently fulfill financial functions: they allow for price hedging, risk transfer, and future value speculation. Globally, most jurisdictions—including the U.S. and EU—already regulate crypto derivatives under existing financial laws.
Japan’s FIEA already provides a legal basis for regulating any derivative tied to assets with significant price volatility and widespread ownership—even if those assets aren’t traditional securities. Given Bitcoin’s market maturity and user base, it clearly meets these conditions.
Furthermore, unregulated margin trading has been accused of fueling excessive speculation, increasing investor vulnerability, and enabling capital flight to offshore platforms. With cross-border crypto trading easily accessible online, domestic restrictions alone won’t stop usage—but they can protect local investors.
Proposed Regulatory Framework
If crypto derivatives are brought under FIEA jurisdiction, exchanges offering these products would need to comply with strict operational standards modeled after foreign exchange (FX) derivative rules. Key requirements include:
- Minimum capital and net worth thresholds
- Robust internal compliance systems
- Clear pre-contract disclosures to clients
- Segregation of customer and company funds
- Advertising controls to prevent misleading promotions
- Mandatory risk warnings before trade execution
Most critically, the FSA is proposing strict limits on leverage, particularly for retail investors.
Leverage Cap: 2x or 4x?
Currently, some Japanese exchanges allow up to 25x leverage, mirroring FX trading limits. However, the Japan Virtual Currency Exchange Association (JVCEA)—a self-regulatory body formed after the 2018 Coincheck hack—had previously proposed a 4x cap as a compromise.
But at the latest workshop, many participants argued for aligning with European standards, where ESMA caps crypto derivative leverage at 2x for retail investors. This stricter limit reflects the higher volatility of digital assets compared to fiat currencies.
While JVCEA Chair Taisei Okuyama acknowledged that 4x was a temporary benchmark, he emphasized that optimal leverage should vary by asset based on volatility, settlement risk, and funding exposure.

Transition Measures and Compliance Timeline
To avoid market disruption, the FSA proposed a six-month grace period for existing unregulated exchanges:
- Operators may continue business temporarily but must adhere to new rules immediately
- Those applying for registration within six months remain under supervision until approval or rejection
Unregistered platforms must:
- Refrain from adding new trading pairs
- Halt customer acquisition efforts
- Clearly disclose their unregistered status
- Avoid implying future approval
These measures aim to prevent misleading marketing while giving compliant firms time to adapt.
Public Reaction: Fear of Capital Flight
Unsurprisingly, the proposed 2x cap has sparked backlash among retail traders.
Many Japanese users argue that overly restrictive rules will push them toward offshore exchanges offering higher leverage—or back into traditional FX trading.
Cools America: “It’s not like we have to use Japanese exchanges…”
Shirahomura: “They’re blaming crypto for exchange failures. If stop-loss doesn’t work, isn’t that the exchange’s fault? Now money will just flow overseas—to black markets or unregulated platforms. Great job, FSA.”
Uwasa no K: “Now it’s either offshore high-leverage exchanges or back to FX margin trading.”
There's legitimate concern that heavy-handed regulation could erode Japan’s domestic crypto ecosystem rather than strengthen it.
Final Outlook: A Balancing Act
Japan stands at a crossroads. On one hand, protecting retail investors from extreme volatility and platform failures is crucial. On the other, excessive restrictions risk driving innovation and capital abroad.
The final leverage cap—likely between 2x and 4x—will reflect this balancing act. Either way, the era of unrestricted 25x margin trading in Japan appears to be ending.
As global regulators converge on tighter crypto oversight, domestic exchanges must prioritize compliance, transparency, and risk management—or risk losing users to more flexible international platforms.

Frequently Asked Questions (FAQ)
Q: Why is Japan considering a 2x leverage cap for crypto trading?
A: Due to the high volatility of cryptocurrencies, regulators believe lower leverage protects retail investors from rapid liquidations and large losses during market swings.
Q: Are all crypto trades in Japan going to be limited to 2x leverage?
A: Not necessarily. The 2x cap is under discussion and primarily targets retail investors. Professional traders may face different rules. The final decision could settle between 2x and 4x.
Q: Will Japanese traders move to overseas exchanges?
A: Yes—many already have. With platforms outside Japan offering up to 100x leverage, stricter domestic rules increase the incentive to trade offshore despite associated risks.
Q: Is margin trading being banned in Japan?
A: No. The goal is not prohibition but regulation—to ensure fair practices, investor protection, and market integrity through capital requirements and risk controls.
Q: How does this compare to regulations in other countries?
A: Japan’s proposed rules mirror Europe’s ESMA guidelines (2x cap), while more lenient than the U.S., where most retail crypto derivatives are restricted entirely.
Q: What happens to unregistered exchanges offering margin trading?
A: They must stop acquiring new customers, avoid expanding services, and clearly disclose their unregistered status—or face enforcement actions.
