Fed Faces Treasury Market Volatility Ahead of Critical Policy Meeting

The US Treasury market recorded its most volatile session in months on 30 December 2025. The 10-year yield swung 15 basis points before closing at 4.35%, just one week before the Federal Reserve’s final policy meeting of the year.

Analysts noted that conflicting economic signals and positioning ahead of Friday’s jobs report drove these market moves. Jane Williams, fixed income strategist at Capital Research Group, stated that the market is caught between inflation concerns and growth fears. The pre-meeting volatility reflects genuine uncertainty regarding the Federal Reserve’s next steps.

Treasury Secretary Janet Yellen, speaking at a banking conference, noted that liquidity metrics remain within historical norms despite this increase in volatility. She emphasized that the Treasury Department is closely monitoring market functioning, especially as the year draws to a close.

EU Carbon Border Tax Implementation Delayed

The European Commission has delayed the implementation of its Carbon Border Adjustment Mechanism (CBAM) by six months, moving full enforcement to July 2026. Officials cited technical challenges in harmonizing reporting systems among member states.

Industry groups responded positively to the postponement. The European Steel Association described it as a necessary step to ensure proper implementation. The CBAM aims to curb “carbon leakage” by requiring importers to buy certificates equal to the carbon costs that would have applied under EU rules.

The Chinese Commerce Ministry reaffirmed its view that the CBAM constitutes “green protectionism” and called for multilateral solutions through the World Trade Organization. Bilateral talks between EU and Chinese officials are scheduled for February 2026.

California Expands Electric Vehicle Infrastructure Requirements

The California Air Resources Board has approved regulations requiring all new commercial buildings to install electric vehicle charging infrastructure beginning in July 2026. This measure extends previous rules for residential buildings and mandates at least 20% of parking spaces in new commercial developments be EV-ready.

Governor Eleanor Sanchez stated that this decision strengthens California’s leadership in clean transportation. The state’s goal is to have 5 million zero-emission vehicles on the road by 2030.

Industry analysts project compliance costs between $8,000 and $12,000 per required charging station. Statewide implementation could reach $1.2 billion over five years. Development associations noted concerns about the financial burden on smaller projects.

UK Digital Markets Bill Advances with Cross-Party Support

The UK Parliament moved the Digital Markets Bill to its final reading on 30 December 2025, following broad cross-party support. The legislation grants new powers to the Digital Markets Unit to enforce conduct requirements on technology companies identified as having “strategic market status.”

The bill advanced swiftly after amendments addressing concerns about its impact on startup innovation. Technology Minister Andrew Hughes stated that the legislation balances competition with digital innovation.

Major technology firms, including Google and Meta, voiced reservations through their industry association, arguing that the legislation creates regulatory uncertainty at a critical time for UK technology investment. The final vote is anticipated by mid-January, with implementation expected in the third quarter of 2026.

South Korea Fines Amazon for Algorithm Transparency Violations

South Korea’s Fair Trade Commission has fined Amazon $28.5 million for not disclosing changes to its product ranking algorithm to third-party sellers. This is the first significant penalty under the reformed E-Commerce Transparency Act.

Commission chairperson Kim Min-jun said Amazon deliberately obscured key changes to its recommendation system that materially affected seller visibility. Investigators found algorithm adjustments gave preference to products with faster shipping times without adequate notification to marketplace participants.

Amazon stated it would appeal, arguing that its policies prioritize consumer experience while offering sellers general optimization guidance. Legal experts believe this case could influence future algorithm transparency requirements in other jurisdictions.
