According to Wallstreetcn, a European Commission official reiterated that the EU aims to complete a full revision of tax reporting rules by the end of this year and pass a separate bill by the end of 2027 to simplify EU tax rules. Benjamin Angel, director of the European Commission's direct taxation department, said at an online conference hosted by the U.S. branch of the International Fiscal Association that the comprehensive simplification proposal would exempt large multinational groups from complying with some EU anti-tax-avoidance rules and is expected to be approved by the end of 2027.

The U.S. Federal Aviation Administration approved Boeing to produce and deliver an additional 35 777F freighters, allowing the aircraft to keep receiving airworthiness certificates after new emissions rules take effect in 2028. According to Sina Finance, the waiver runs through December 31, 2030, and applies only to 35 newly built aircraft. Under the approved plan, Boeing may apply for original airworthiness certificates for up to 35 777Fs after January 1, 2028. The article said Boeing expects to complete the batch in about 18 months at a production pace of roughly two aircraft per month. The waiver does not give the 777F a long-term exemption from emissions standards. Existing 777Fs are not affected by the new rules, which apply to newly produced aircraft first certified from 2028 onward. The article said the U.S. rules use aircraft carbon certification standards set by the International Civil Aviation Organization. Some subsonic jets must meet new fuel-efficiency and greenhouse-gas emissions thresholds from 2028, and the current 777F would otherwise have had to end production by the end of 2027.

According to CNBC, Breakout Capital founder Ruchir Sharma said a decisive move above 5% on the 10-year Treasury yield could hurt equity markets broadly and put the artificial intelligence trade under particular pressure. He said the 10-year Treasury is the most important asset in the world because it affects stock valuations and sets borrowing costs for mortgages, auto loans and other debt, and he added that equity prices tend to fall when yields rise above 5.25%. The benchmark 10-year yield touched 5% earlier this week and a 19-year high before easing 5 basis points Thursday to 4.94%. Sharma also said persistent inflation and higher interest rates have historically ended major market booms, while Goldman Sachs said higher capital costs and greater capital intensity in tech have reduced the value of future cash flows.

According to Sina Finance, Russian President Vladimir Putin said the government is preparing a 2027 federal budget that is expected to keep the deficit at about 2% of GDP. The budget uses a conservative oil price assumption of about $50 per barrel, and social security, public safety, and defense capacity building will remain priorities. Putin said the deficit level is broadly manageable and that the government will arrange revenues and spending based on relatively cautious energy price expectations. The new target is above the 1.3% of GDP deficit outlined for 2027 in the earlier 2026-2028 budget framework, which had planned to finance the gap mainly through higher government borrowing. Putin also said the 2027 budget will prioritize social commitments, public safety, and defense capabilities.

According to CNBC, policy experts say President Donald Trump's tax legislation has benefited Americans unevenly, even as Republicans promote the bill ahead of the midterm elections. The law, also called the Working Families Tax Cuts, made permanent Trump's 2017 tax changes and added new deductions for tip income, overtime earnings, seniors and auto loan interest, along with a larger federal SALT deduction limit for itemizers. Treasury Secretary Scott Bessent told the House Committee on Financial Services this week that the legislation delivered tax relief directly to millions of low- and middle-income Americans. He also said more than 64 million tax returns claimed at least one of the bill's signature new tax cuts. White House spokesman Kush Desai said tens of millions of Americans have used at least one of the provisions. The Tax Foundation said 62% of Americans would have faced tax increases in 2026 if the 2017 tax cuts had expired, and Garrett Watson said most of the benefit came from making those provisions permanent rather than from the new deductions. The average tips deduction was more than $7,000 and the average senior deduction was more than $7,500, according to Treasury data. The SALT deduction cap rose to $40,000 for 2025 from $10,000 in 2024, and Watson said it is most beneficial to upper-middle- to upper-income earners because it phases out at $500,000. As of May 8, the average individual tax refund was $3,276 for the 2026 filing season, up 11.5% from roughly the same point last year, according to IRS data.

OpenAI has reported new AI safety incidents and outlined a disclosure plan, according to Bloomberg. Bloomberg News AI reporter Shirin Ghaffary called the disclosures a "watershed moment" in public understanding of AI risks as models become more powerful and employees issue warnings. She said aligning AI models with companies' intended goals remains unresolved and is a "big, big problem" as AI use expands.
