The Bank of Korea launched an official review to see how 31 traditional banks and stockbrokers would survive a massive cryptocurrency crisis. The central bank sent a survey to 18 domestic banks and 13 securities firms to test their business limits if a major crypto exchange suffered a hack or if the price of Bitcoin suddenly crashed.
The Bank of Korea sent 31 banks and brokerages a survey on how they’d handle a major exchange hack or a sharp Bitcoin drop.
Does this kind of central bank review change how you think about the risk of holding crypto on exchanges? https://t.co/XCaAC8DVRH

This move shows that the government now views digital money crashes as a direct threat to the traditional banking system. The discussion focused on the risks of leaving digital assets on cryptocurrency exchanges. @Utpal on X argued that investors should consider keeping their coins in personal wallets rather than relying entirely on trading platforms.
@Nguyen123Q It reinforces the importance of self-custody and understanding exchange risks.

Another user on X, @Nine highlighted the growing concern about exchange failures, noting that central bank stress tests show why investors should take the possibility of financial trouble seriously.
@Nguyen123Q Custody risk feels more real when regulators are stress testing the downside

Meanwhile, also on X, @Ashkan pointed out that holding assets on an exchange exposes investors to two risks: losing money when crypto prices fall and potentially losing access to their funds if the exchange goes bankrupt.
@Nguyen123Q Yes. It reinforces that exchange custody carries counterparty risk beyond Bitcoin’s price volatility.

When a crypto exchange collapses, the panic instantly spreads to the traditional banking system and causes a massive bank run. Crypto exchanges do not hold their own physical cash. They keep their customers’ dollars in regular, government-regulated banks.
When a crypto exchange deposits one billion dollars into a regular bank, the bank does not keep that cash in a safe. It uses that cash to buy long-term investments, like government bonds, to make a profit. It only keeps a very small fraction of physical cash on hand. If the crypto exchange suddenly demands its entire billion dollars back on the exact same day because of a digital hack, the regular bank is completely trapped.
Silvergate Bank’s collapse in 2023 showed how a crypto crash can damage traditional banks. After FTX went bankrupt, customers rushed to withdraw billions from crypto companies, triggering an $8.1 billion bank run on Silvergate. The bank was forced to sell its long-term bond investments at a heavy loss to meet withdrawals, losing nearly $1 billion. The losses eventually led to its liquidation, showing how problems in the crypto market can spread into the traditional banking system.
When you deposit digital money into a crypto exchange or lending platform, you instantly lose legal ownership of your assets. The exchange controls the digital master keys, known as private keys. The company is legally allowed to use your deposited funds to pay off its own corporate debts before it pays you.
The Celsius Network collapse in 2022 showed the risks of leaving cryptocurrency on an exchange. After the platform went bankrupt, a court ruled that crypto held in its interest-bearing accounts belonged to Celsius, not its customers. This left many users unable to recover their funds.
To avoid this exact disaster, investors can move their cryptocurrency into personal hardware wallets. These small devices store private keys offline, giving users direct control over their assets instead of relying on an exchange. This reduces the risk of losing access to funds if a platform is hacked or goes bankrupt.
Starting in December 2026, the South Korean government will activate strict new rules for sending cryptocurrency across international borders. Lawmakers will stop treating digital coins like simple internet trading assets. Instead, they will legally classify stablecoins, like USDT and USDC, as formal payment instruments under the country’s foreign exchange laws.
If an investor in Seoul wants to send their digital dollars to an international exchange or a private foreign wallet, they can no longer do it silently. The new law forces crypto transfer businesses to register and report these cross-border transactions directly to the government.
The government will monitor digital stablecoin transfers exactly the same way they track traditional bank wires sent to another country. This new rule builds a digital fence around the market, ensuring that investors can no longer move their crypto wealth out of South Korea without the government watching every single transaction.
Meanwhile, South Korean President Lee Jae Myung hasconfirmed a coordinated cyberattack targeting the country’s financial sector. He has ordered government agencies to send personnel and resources immediately to contain the damage.
