US Inflation Data Shifts Market Expectations

Global markets reassessed interest-rate expectations on Tuesday after US consumer prices increased more than anticipated in October.

The Consumer Price Index rose 0.4% during the month, following a 0.6% increase in September. Economists had expected a monthly gain of 0.3%, making the latest reading an upside surprise for investors already concerned about persistent price pressures.

Higher energy prices and lingering tariff effects were identified as important contributors to the inflation overshoot.

The data strengthened expectations of additional Federal Reserve tightening. Traders are now fully pricing in two quarter-point rate increases by March, with the first expected in December.

Federal Reserve Governor Christopher Waller had earlier argued that borrowing costs should increase next month, even if inflation showed signs of cooling. He also indicated that a larger half-point increase should be considered if the inflation outlook deteriorated.

Treasury Yields and Dollar Strengthen

The inflation report triggered a rise in US Treasury yields and supported the dollar against major currencies.

The two-year Treasury yield, which is particularly sensitive to expectations for Federal Reserve policy, increased 14 basis points to 4.69%.

The US dollar strengthened against both the Japanese yen and the euro as investors adjusted their expectations for the interest-rate outlook.

The movements reflect renewed pressure on financial markets as the prospect of higher borrowing costs competes with improving sentiment around energy prices and geopolitical developments.

European Stocks Remain Near Record Levels

European equities retained modest gains despite losing momentum following the US inflation release.

The STOXX 600 was up 0.6%, remaining less than 1% below its record high. Lower oil prices had initially supported the region’s markets by easing some concerns about inflation and energy-related costs.

Brent crude futures declined more than 3.2%, moving below $90 per barrel for the first time since late August. Investors responded to expectations that diplomatic discussions between the United States and Iran could reduce the risk of further military escalation.

However, the stronger-than-expected US inflation reading shifted attention back toward monetary policy and contributed to the reduction in European equity gains. US stock futures also indicated a lower opening.

AI Stocks and Anthropic IPO Remain in Focus

The artificial intelligence sector continues to influence broader market sentiment following last week’s sharp correction and Monday’s recovery.

The S&P 500 recorded its largest one-day gain since April on Monday, while the Nasdaq advanced 2.7%, its strongest session in more than three months. Asian markets also rebounded, with South Korea’s KOSPI gaining 4.4% and Japan’s Nikkei rising 2.9%.

Attention remains on Nvidia following an investigation into whether CEO Jensen Huang had been targeted by a foreign intelligence operation. The company is also facing scrutiny over allegations involving a Chinese businesswoman. Nvidia shares fell 1.4% in premarket trading after declining 4.3% on Monday.

The company is scheduled to report earnings next week.

Meanwhile, Anthropic’s proposed IPO could value the AI company at up to $1.4 trillion. The offering is expected to test investor confidence in the sector following the recent reassessment of AI valuations and concerns about the cost and profitability of infrastructure investment.

Earnings from technology companies, including CoreWeave, will provide additional insight into investor appetite for the AI infrastructure expansion.

What Investors Should Watch Next

The Federal Reserve’s December policy decision remains a central market consideration following October’s stronger inflation reading. Treasury yields and the dollar may remain sensitive to incoming economic data and further comments from policymakers.

Investors will also be watching whether the equity recovery can withstand higher borrowing-cost expectations. Nvidia’s upcoming earnings, developments surrounding its CEO and the progress of Anthropic’s IPO will provide further tests of sentiment toward the AI sector.

Meanwhile, oil prices and developments in US-Iran diplomacy remain important variables for inflation expectations and global risk appetite.
