Summary
The Ethereum Foundation has recently undergone a leadership reshuffle, leading to a strategic shift towards enhancing user experience and tackling layer-1 scaling issues. Co-executive director Tomasz Stańczak highlighted that this change allows Ethereum co-founder Vitalik Buterin to dedicate more time to research and exploration, rather than managing daily operations. Since stepping back, Buterin has proposed significant upgrades to Ethereum's privacy and performance, including a privacy roadmap and changes to the Ethereum Virtual Machine's contract language to boost efficiency. The Foundation is now focusing on near-term goals like protocol upgrades, with emphasis on layer-1 scaling, support for layer-2 solutions, and improving user experience through upcoming upgrades like Pectra, Fusaka, and Glamsterdam. These efforts aim to not only address immediate challenges but also pave the way for long-term projects that could revolutionize Ethereum's execution and consensus layers.

Summary
US stocks advanced on Tuesday, with the S&P 500 setting a new record close at 6,909.79, up 0.5%, while the Nasdaq Composite rose 0.6% and the Dow Jones Industrial Average gained 0.2%, marking a fourth consecutive session of gains. Despite strong economic data revealing a 4.3% annualized GDP growth in Q3—exceeding the expected 3.3%—investors scaled back expectations for imminent Federal Reserve rate cuts, with odds of a January cut dropping. Precious metals, including gold and silver, continued their remarkable rally, hitting new highs and on track for their best year in over 40 years, while copper also reached a record above $12,000 per ton. However, consumer confidence fell for the fifth straight month, indicating persistent economic unease. On the corporate side, Novo Nordisk’s stock surged after US approval of its Wegovy weight-loss drug. Meanwhile, discussions around revising the Fed’s 2% inflation target to a range-based system emerged, and government spending increased despite a reduction in federal workforce under the Department of Government Efficiency. As markets head into the Christmas holiday, early closures and full-day closures are scheduled for Wednesday and Thursday, respectively.

Key Points
Summary
The past year at the Federal Reserve was marked by a rare conflict between its goals of maximum employment and stable prices, echoing 1970s stagflation, and resulting in significant internal divisions over interest rate policies. Despite this, Chair Jerome Powell secured consensus for three rate cuts in 2025, though future chairs may face challenges if inflation remains high and the job market weakens. President Trump’s economic policies, including tariffs and immigration curbs, alongside his pressure on the Fed and threats to remove Powell, sparked fears over central bank independence. Tariffs initially had a milder-than-expected impact on inflation, but concerns persist about sustained price pressures into 2026, exacerbated by data gaps from a record government shutdown. The labor market showed signs of cooling, prompting dissents within the Fed on whether to prioritize inflation or employment. Looking ahead, the Fed plans a cautious approach with only one rate cut expected in 2026, as it navigates a muddy economic picture, fiscal tailwinds, and ongoing inflation above its 2% target. A new Fed chair, likely favoring lower rates, will inherit these challenges amid questions about independence and economic forecasts.

Summary
US airlines are gearing up for a record-breaking holiday season, expecting an average of 2.9 million passengers daily from Dec. 19 to Jan. 5, a 1.5% rise from last year, according to Airlines for America. Domestic round-trip airfares are set to average $900, up 7% from 2024. Major airports are also bracing for significant increases, with New York and New Jersey expecting 5.7 million travelers (1% up), Chicago’s airports preparing for 4.8 million (6% up), and Dallas Fort Worth anticipating 5 million (3.2% up). However, the year has been turbulent for airlines, with economic uncertainty sparked by President Trump’s April tariff announcement and a government shutdown in autumn leading to temporary flight cuts at 40 major airports due to staffing shortages at the Federal Aviation Administration. Additionally, ongoing airport renovations in cities like New York and Chicago are causing potential delays, with authorities advising travelers to plan for construction and traffic congestion. Despite these challenges, bookings saw a recovery over the summer, setting the stage for a busy holiday travel period.
