The week of June 22 to June 28 brings together macroeconomic data, technology-sector events, digital finance policy discussions and blockchain infrastructure updates. Last week, the United States and Iran signed a preliminary agreement, creating room to extend a ceasefire, restore shipping through the Strait of Hormuz and advance follow-up nuclear talks. As a result, investors’ expectations for a further easing of Middle East tensions rose noticeably. In parallel, SpaceX’s planned bond issuance, Micron Technology’s earnings release, US economic indicators, a US House roundtable on digital finance and Base’s mainnet Beryl hard fork are all scheduled or flagged as items to follow during the week.
June 22: South Korea’s financial AI rules and Marvell’s S&P 500 inclusion
On June 18, South Korea’s Financial Services Commission released a revised version of its Guidelines on Artificial Intelligence in the Financial Sector. The guidelines will take effect on June 22 and apply across the financial industry as well as to FinTech companies. The new rules cover financial companies that introduce AI and FinTech firms whose services affect financial transactions. They establish seven principles: governance, legality, subsidiarity, trustworthiness, financial stability, fiduciary duty and security.
The South Korean government also plans to ease certain network isolation security regulations that apply to some financial institutions. It will improve the consent system for personal credit information, refine rules for data anonymization and combination, and study responsibility and authority rules for AI Agents as well as dedicated regulatory plans for AI. On the same day the guidelines take effect, South Korea’s Financial Supervisory Service will release an AI risk management framework for the financial sector, while the Financial Security Institute will publish AI security guidelines for the financial industry.
Also on June 22, S&P Dow Jones Indices announced that Marvell Technology (MRVL) will officially be added to the S&P 500 Index. Following the announcement, Marvell Technology rose more than 7% in US pre-market trading. Flex also gained after being included in the S&P 500. The index changes and the implementation of South Korea’s financial AI framework will both sit on the early-week calendar.

After the US market close on June 24, memory-chip giant Micron Technology will report its latest results and guidance.

US Representative William Timmons, the Republican chair of the House Military and Foreign Affairs Subcommittee, announced that a roundtable will be held on June 25. The meeting will focus on how digital assets and cryptocurrencies can help individuals protect wealth, access aid and maintain economic autonomy. The roundtable will also examine the intersection between digital finance and US national security interests, as well as how the United States can maintain competitiveness in digital finance by promoting financial innovation.

Base, the Layer 2 network under Coinbase, is preparing to launch the Beryl hard fork. The upgrade introduces the B20 native token standard, shortens the final confirmation period for single-proof withdrawals from seven days to five days, and upgrades to Reth V2. The Reth V2 upgrade reduces disk usage by 50% and increases throughput by 33%. Beryl is scheduled to activate on the Sepolia testnet at 2:00 a.m. UTC+8 on June 19 and on the mainnet at 2:00 a.m. UTC+8 on June 26.
B20 is Base’s native token standard. It is an ERC-20 compatible token implemented with Rust precompiles and designed for stablecoin, RWA and long-tail token issuers. The standard includes a built-in compliance toolkit, covering transfer policies, freezing and seizure, role-based access control, memos and supply caps. For withdrawals, the final judgment window for the single-evidence dispute resolution process will be reduced from seven days to five days. The dual-proof fast path introduced by Azul, based on TEE and ZK, remains at one day.
After June 26: QKC network support and SpaceX’s bond plan
Binance also announced that it will stop supporting deposits and withdrawals of QuarkChain (QKC) tokens through the BNBSmartChain network at 16:00 Beijing time on June 26, 2026. After that time, deposits made through the network will not be credited to accounts and may result in asset losses. Users can still deposit and withdraw through other networks supported by Binance. No specific events were listed for June 28.
Among items without a confirmed date, sources said SpaceX’s partner banking team may begin investor calls as soon as next week to discuss a bond issuance plan after the company completes a record IPO. According to the sources, the bond sale is expected to be at least $20 billion, with investor communication starting as early as Monday. The plan and timing may still change. SpaceX plans to issue investment-grade US dollar bonds for the first time, using the proceeds to refinance a $20 billion bridge loan due in September 2027. The IPO filing submitted by SpaceX to the US Securities and Exchange Commission shows that, as of March 31, the bridge loan accounted for the majority of the company’s $29.1 billion in long-term debt. Sources said Bank of America, Citi, JPMorgan, Goldman Sachs and Morgan Stanley jointly provided the bridge loan and will lead the underwriting of the bond issuance.
