Microsoft has unveiled the next phase of its collaboration with OpenAI, marking a significant development in their ongoing partnership. According to Jin10, this announcement highlights the continued integration of advanced AI technologies into Microsoft's offerings, aiming to enhance user experience and expand capabilities across various platforms. The partnership is expected to drive innovation and provide new opportunities for both companies in the rapidly evolving AI landscape.

Microsoft's licensing agreement with OpenAI is transitioning to a non-exclusive arrangement. According to Jin10, this change allows other companies to potentially access OpenAI's technology, which was previously exclusively licensed to Microsoft. The shift in licensing terms may impact the competitive landscape in the AI industry, as more firms could integrate OpenAI's capabilities into their products and services.

Two oil tankers linked to Iran, intercepted by the U.S. military near Sri Lanka last week, are currently heading west. According to Odaily, the Pentagon announced that the U.S. military conducted 'maritime interception and boarding inspections' on the supertankers 'Tiffany' and 'Phoenix' on April 21 and 23, respectively. However, details regarding the subsequent handling of these vessels were not disclosed. The digital signals from the tankers indicate they are traversing the Indian Ocean in a westward direction. The U.S. has not officially stated its intentions regarding the disposition of these oil tankers, which continue to transmit the same destination signals as during the interception, adding to the uncertainty about their current whereabouts.

The European Blockchain Association, Blockchain for Europe, released a report on Monday highlighting concerns over the European Union's Markets in Crypto-Assets (MiCA) regulation framework. According to Foresight News, the report argues that while MiCA has enhanced the security of euro stablecoins, it has significantly reduced their commercial competitiveness. As a result, euro stablecoins account for less than 1% of global stablecoin trading volume, which is disproportionately low compared to the euro's actual global market presence. The report, co-authored by European Central Bank official Ulrich Bindseil and Blockchain for Europe's Erwin Voloder, criticizes two core restrictions of MiCA on euro electronic money tokens (EMT): the prohibition of interest payments to holders and the requirement for at least 30% (60% for major issuers) of reserves to be held in bank deposits. The report suggests that in a positive interest rate environment, the interest ban places euro stablecoins at a disadvantage compared to bank deposits and foreign currency stablecoins with embedded yield mechanisms. This combination of restrictions has pushed euro stablecoins into a regulatory 'Laffer Curve' downturn, where stricter regulation leads to a contraction in the intended market activity. EU officials have begun discussing the direction of a "MiCA 2.0" revision. However, the European Banking Authority (EBA) has previously warned that changes to related technical standards could weaken security measures and increase arbitrage risks. Additionally, the European Central Bank's macroprudential analysis this month noted that widespread adoption of euro stablecoins could lead to concentrated demand for short-term eurozone government bonds, affecting yields and liquidity during large-scale redemptions.

Microsoft has announced that it will no longer pay revenue shares to OpenAI. According to Jin10, this decision marks a significant shift in the partnership between the two companies. Microsoft had previously been sharing revenue with OpenAI as part of their collaboration. The change in terms could impact the financial dynamics of their ongoing projects and collaborations.

先週、スリランカ近海で米軍に拿捕されたイラン関連のタンカー2隻は、現在西へ向かって航行している。米国防総省は先週、米軍が4月21日と23日にそれぞれ超大型タンカー「ティファニー」号と「フェニックス」号に対し「海上阻止・登船検査」を実施したと発表したものの、両船のその後の処遇については詳細を明らかにしなかった。両タンカーのデジタル信号によると、現在は一隻がもう一隻の後ろを追い、インド洋を横断して西へ向かって航行している。米国は、これら2隻のタンカーに対する具体的な処置方針をまだ正式に明らかにしていない。両船は依然として、阻止措置が行われた際と同じ目的地信号を送信しており、これが外部からの現在の行方に対する困惑をさらに深めている。（金十）
