Ban, License or Court? Four Asian Approaches to Controlling Crypto

No region shows the range of state responses to crypto more vividly than Asia. Mainland China has banned crypto trading and mining outright. A few kilometers across the border, Hong Kong actively courts exchanges and stablecoin issuers. Singapore, once the region's most welcoming hub, tightened its rules after a series of painful collapses. Japan, scarred by early exchange failures, built one of the world's first licensing regimes. Each model reflects a distinct view of what money is for and who should control it.

China: prohibition as capital control

China's hostility to crypto developed in stages. Authorities barred financial institutions from handling bitcoin in 2013, banned initial coin offerings and pushed domestic exchanges out in 2017, and in 2021 declared crypto transactions illegal while ordering a crackdown on mining, which at the time accounted for a large share of global bitcoin hash rate. The logic is consistent with the country's broader financial system. China maintains strict capital controls, and permissionless crypto offers a route around them. At the same time, the People's Bank of China has pushed ahead with its own digital currency, the e-CNY, which gives the state more visibility over payments rather than less.

The ban has not eliminated activity. Peer-to-peer trading and offshore platforms continue to serve mainland users, and mining partly relocated rather than disappeared. But the policy has kept crypto out of the formal financial system and signaled clearly that monetary sovereignty comes first.

Hong Kong: the licensed gateway

Hong Kong took the opposite path, especially after 2022, when the government issued a policy statement signaling its intention to become a hub for virtual assets. A mandatory licensing regime for crypto trading platforms took effect in 2023, allowing licensed exchanges to serve retail investors under strict conditions. The city approved spot bitcoin and ether exchange-traded funds in 2024 and brought a stablecoin licensing regime into force in August 2025, under which the Monetary Authority has said it will be highly selective.

Hong Kong's approach is often read as a controlled experiment conducted with Beijing's tolerance. It allows China to observe and participate in digital-asset markets through a separate legal system without opening the mainland. Whether that tolerance extends to products that could facilitate capital flows out of the mainland is a question that shapes what Hong Kong regulators are willing to approve.

The city has also learned from its own mistakes. A 2023 scandal involving an unlicensed platform that marketed aggressively to local investors, and was later the subject of police action over alleged fraud, reinforced the regulator's insistence that only licensed venues should reach the public. Hong Kong's pitch to global firms is therefore not that it is permissive, but that it is predictable: a clear list of what is allowed, a demanding approval process and a regulator willing to publish warnings about unlicensed operators. Whether that balance produces a durable hub or a small, heavily supervised niche remains to be seen.

Singapore: from welcome mat to high bar

Singapore's Payment Services Act, in force from 2020, created an early licensing path, and the city attracted a wave of crypto firms. The collapses of 2022 changed the mood. Terraform Labs and the hedge fund Three Arrows Capital both had significant ties to Singapore, and their failures caused losses worldwide. The Monetary Authority of Singapore responded with stricter consumer protection rules, restrictions on marketing crypto to the public and a framework for stablecoins. In mid-2025, new rules took effect requiring Singapore-based firms that serve only overseas customers to be licensed, which in practice pushed out companies that had used the city as a base without local oversight.

Singapore learned what every financial center eventually learns: a reputation for welcoming everyone is a reputation you end up paying for.

Japan: regulation born of failure

Japan's framework grew out of crisis. The collapse of Tokyo-based Mt. Gox in 2014, then the largest bitcoin exchange, led to amendments requiring exchanges to register with the Financial Services Agency from 2017. A large hack of the Coincheck exchange in 2018 brought tighter rules on custody and cold storage. In 2022, Japan legislated to restrict stablecoin issuance to banks, trust companies and licensed money transfer firms. The result is a conservative but predictable regime. Customer assets at Japanese exchanges were largely protected when FTX collapsed in 2022 because local rules required segregation. Policymakers have since debated treating crypto more like conventional financial products for tax and disclosure purposes.

Common threads

• Each regime is shaped by a formative crisis or a strategic priority, not by abstract principles.
• Stablecoins are treated as closer to money than to speculative assets, and therefore kept close to the state.
• Retail access is the political fault line: allowing it brings business, restricting it limits losses.

South Korea, the home market of Terraform Labs, offers a fifth variation. After the Terra collapse caused heavy losses for many domestic retail investors, the country passed a user protection law that took effect in 2024, focusing on custody and market abuse. Debates over allowing institutions and corporate accounts into the market continue.

What Asia teaches the rest of the world

The Asian experience suggests that crypto regulation is less about technology than about the state's broader bargain with its financial system. Countries with tight capital controls see crypto as a threat to be contained. Financial centers see it as business to be won, carefully. Countries that suffered early losses prioritize custody and consumer protection above all. As the US and EU refine their own regimes, these models offer a menu of choices and a warning that every choice carries costs. This analysis is not investment advice.
