South Korean crypto exchange Bithumb said an outsider breached an internal employee mobile system used for work and messaging, and personal information was stolen, though no cryptocurrency funds have been reported lost. The exchange says the system is separate from its trading platform, but has not disclosed how many people were affected or whether deposits and withdrawals were disrupted. The breach comes amid cyberattacks on South Korean financial firms: the Financial Supervisory Service said 16 firms had been hit as of Oct. 14, and Daishin Securities reported a leak affecting 38,490 customers. It is Bithumb's second control lapse this year, after it mistakenly credited customers with 620,000 BTC, worth more than $40 billion at the time, instead of 620,000 won in February.

- Bithumb discloses data leak after internal system breach: Report
South Korean crypto exchange Bithumb is investigating the extent of a data leak after hackers breached its in-house mobile system, which employees use for internal communication and work, earlier this week. Bithumb discovered the breach on Tuesday and notified the Korea Internet & Security Agency and the Personal Information Protection Commission the same day. The exchange said its internal work system is separated from its virtual asset trading system, so customer virtual assets could not be accessed through this breach, while it was still checking whether member data was involved. The incident is part of a wave of cyberattacks on South Korea's financial sector, with 16 financial firms hit as of October 14, according to Governor Lee Chan-jin. Daishin Securities said personal and credit information of 38,490 customers had been leaked.
- South Korea plans cybersecurity overhaul after attacks hit banks, crypto firms
South Korea’s Financial Services Commission (FSC) is proposing tougher cybersecurity assessments after a review found deficiencies at 130 of 555 financial companies. Earlier security incidents involved 16 firms, including crypto exchanges, and exposed about 100,000 pieces of customer information such as names, contact details and ID numbers. Affected firms include Gopax operator Streami and crypto platform Prabang, which disclosed that an Oct. 2 hack exposed some customers’ personal info. Proposed reforms include vulnerability assessments at least twice a year for larger institutions, better information-sharing, possible AI-assisted monitoring for smaller firms, and extra inspections when urgent threats emerge. The FSC is still investigating whether AI was used in the incidents or whether they were linked to the same attackers.
- South Korea lawmakers mull pushing crypto tax implementation to 2029
South Korean government officials are reportedly weighing another delay to the crypto income tax, currently set to take effect on January 1, 2027. According to Newsis, the tax could be pushed to 2029, partly because that is the earliest point at which information on digital asset exchange taxes can be shared with the US. The policy imposes a 22% tax on crypto gains (20% income tax and 2% local tax) for investors earning over 2.5 million Korean won ($1,883) a year, and has been delayed several times since it was proposed in 2020. An official said the government is discussing postponing implementation, while the US is scheduled to join the OECD's Crypto-Asset Reporting Framework in 2029 and South Korea will start in 2027. The official reportedly noted that the US accounts for nearly half of the virtual asset market.
- South Korea weighs fourth delay on its crypto gains tax, pushing it to 2029
South Korea is leaning toward delaying its crypto gains tax, due to start in January, until 2029, which would be a fourth postponement. Officials are concerned that users of domestic exchanges would bear most of the burden because the U.S. will not share crypto trading data until 2029, and one official said almost half the crypto market is in the U.S. Deputy Prime Minister Koo Yun-cheol had said in July the tax would take effect in January 2027, but his successor, Lee Hyung-il, said he would gather views from parliament, experts and industry. Under current rules, annual net income from crypto transfers or lending is taxed at 20%, or 22% including local income tax, after a 2.5 million won ($1,887) deduction. Parliament must approve the change, with a final decision expected by early December.
- New DeepSeek ban in US, Swiss-Asia crypto ties deepen: Asia Express
The US Department of Homeland Security has ordered DeepSeek products removed from federal civilian agency IT systems, including affiliates and third-party products built with DeepSeek, and barred agencies from new purchases. The US Treasury has proposed rules blocking investment in AI and certain high-risk semiconductors in some foreign countries, expanding the restrictions to adversaries including Russia, Iran, North Korea and Cuba. It also announced a $200,000 penalty against Amidi, LLC for failing to report a Chinese subsidiary's investment in Shanghai Qiongche Intelligent Technology. Separately, Shinhan Card signed an agreement with SBI units to test yen stablecoin payments and cross-border trade settlement. South Korean finance officials met major crypto exchanges as a lawmaker proposed delaying the crypto tax start date by two years.
- Bitcoin corrects below $82K after Tesla Q3 results, KOSPI falls
Bitcoin reversed a rally toward $85,000 and fell nearly 3% on Thursday after failing to break a resistance trend line near $84,840, dropping back below $82,000. The move followed Tesla's Q3 results, where revenue of $28.05 billion narrowly missed the $28.13 billion estimate, while capital expenditure of $4.73 billion came in far below the projected $7.96 billion, reviving concerns about AI spending. Musk said spending would rise through 2028. South Korea's KOSPI closed down 3.52%, still struggling to recover from last week's low of 5,460 points. Onchain data showed open interest rising 4.5% to $55.95 billion before the reversal, which the article says raises the risk of sharper liquidations, and it flags the $80,000–$81,500 zone as key support.

- Vietnam's financial market in 2027 faces pressure on liquidity and credit quality
Saigon Ratings says Vietnam's financial market showed significant changes in the first nine months of 2026: GDP grew 9.01%, realised total social investment reached about VND 3,109.6 trillion (up 15.1%), and realised FDI reached USD 21.07 billion (up 12.1%). As of 28 September 2026, credit growth was 10.89%, below 13.37% a year earlier and faster than deposit mobilisation (9.78%) by about 1.11%, which could strain liquidity if loan demand rises sharply late in the year. Corporate bond issuance is recovering but diverging across issuers, with heavy maturity pressure in Q4 2026 and 2027, especially in real estate. Average CPI for nine months was 4.52% and the goods trade deficit was USD 19.42 billion, factors that could affect capital mobilisation and credit quality. Saigon Ratings outlines three development scenarios for 2027.

- Tesla-SpaceX Merger Needs No Premium, Investor Says — But Floats $500 To Sway Angry Holders Missing Bigger Payoff
Larry Goldberg of LumaSenti says Tesla shareholders do not need a premium to benefit from a SpaceX merger, but floats $500 a share as a figure that could persuade reluctant investors, and says his priority is completing the deal. He argues that the lower the premium, the higher the value of the SpaceX stock received, and that combining assets and cash flows could help finance a computing buildout he estimates at $500 billion to $1 trillion. Brad Gerstner of Altimeter Capital suggests a $420 to $550 range, while ARK's modeling projects benefits for both shareholder groups from a no-premium swap. Tesla's quarterly filing confirms a special committee is exploring a deeper relationship with SpaceX; Musk says the committees have not agreed on terms and Tesla would need approval from 50% of all shares.
- EU considers reducing reliance on US after Starlink disruption in Ukraine
EU countries are intensifying discussions on building independent defence capabilities and reducing reliance on the US after Starlink was disrupted in Ukraine, Bloomberg reported on 27 October. At the EU summit on 15-16 October, participants discussed the service disruptions and a new public clash between Ukrainian President Volodymyr Zelensky and the White House chief Donald Trump. European officials reviewed options to expand their own capabilities and diversify key technology suppliers, but implementing such plans would take years, so the bloc called for greater European participation in existing structures such as NATO. The article also cites Elon Musk's 24 October claim that Ukrainian forces used Starlink for offensive drone attacks, and Trump's 22 October statement that Ukraine's access to SpaceX's Starshield had been restored.

Strong net inflows into the global wealth management business supported results, with net new assets reaching $55.1 billion by quarter-end and $12.5 billion in client commitments across wealth and asset management. The common equity tier 1 (CET1) capital ratio, a measure of solvency, rose to 14.7% from 14.4% in the previous quarter.
- Oil prices rise as Houthi attacks on Saudi Arabian refinery raise supply worries
Oil prices rose on Wednesday as investors weighed a possibly prolonged and widening Middle East conflict after Tehran-backed Houthis attacked Saudi Arabia's largest refinery, Ras Tanura, with a ballistic missile. Brent rose $1.50, or 1.32%, to $115.59 a barrel, while WTI gained $1.47, or 1.47%, to $101.37. President Trump said the war with Iran would end on his terms and that Tehran must be prevented from acquiring nuclear weapons. Israel's election also appeared headed for a stalemate, as preliminary exit polls showed neither bloc reaching the 61 seats needed in the 120-seat parliament.
