US Inflation Data Reverses Market Momentum
Global equity markets surrendered part of their earlier gains on Tuesday as stronger-than-expected US inflation data reinforced expectations that the Federal Reserve could raise interest rates in December. European shares moved lower from session highs, while US stock futures pointed to a weaker Wall Street opening as investors reassessed the monetary policy outlook.
The US Consumer Price Index (CPI) increased 0.4% in October following a 0.6% advance in September, exceeding economists’ expectations for a 0.3% monthly increase. The latest reading strengthened concerns that inflationary pressures remain persistent despite previous expectations of a moderation.
According to Vanguard senior US economist Josh Hirt, lingering tariff effects and higher energy prices accounted for much of the inflation overshoot.
Market pricing now reflects expectations of two 25-basis-point Federal Reserve rate increases by March, with the first anticipated in December, according to LSEG data.
Treasury Yields and Dollar Strengthen
The inflation figures triggered a notable adjustment in interest-rate markets. The US two-year Treasury yield, which closely tracks expectations for Federal Reserve policy, increased 14 basis points to 4.69%.
The US dollar also strengthened against the Japanese yen and euro as investors adjusted their expectations for monetary policy and relative interest-rate differentials.
Federal Reserve Governor Christopher Waller added to the hawkish outlook, arguing that the central bank should increase short-term borrowing costs next month even if government data showed inflation cooling. He also indicated that a larger half-percentage-point increase could be considered if inflation deteriorated.
The developments suggest that markets are increasingly focused on the possibility that restrictive monetary policy could persist longer than previously anticipated, potentially affecting equity valuations and financing conditions.
European and Asian Markets Maintain Gains
Despite the renewed pressure from US inflation, European equities remained positive. The STOXX 600 was up 0.6%, although it retreated from its session highs and remained less than 1% below its record level.
Lower oil prices provided some support to European markets, easing concerns about energy-driven inflation. Brent crude declined more than 3.2%, falling below $90 per barrel for the first time since late August as investors responded to expectations of potential diplomatic progress between Washington and Tehran.
Asian markets also recorded substantial gains. South Korea’s KOSPI advanced 4.4%, Japan’s Nikkei 225 gained 2.9%, and MSCI’s broadest index of Asia-Pacific shares increased 2%.
The regional recovery followed the previous week’s selloff, which had been driven partly by concerns about AI-sector valuations and the potential regulatory implications of the US midterm election results.
AI Investment and Nvidia Remain in Focus
Technology stocks remain a central source of uncertainty as investors evaluate the financial sustainability of the artificial intelligence investment cycle.
Upcoming earnings from companies including CoreWeave will provide additional insight into the costs and profitability of expanding AI infrastructure. Meanwhile, Anthropic’s anticipated initial public offering, which could value the company at up to $1.4 trillion, is emerging as an important test of investor appetite for AI-related businesses.
Nvidia also remained under scrutiny following reports of an FBI investigation involving CEO Jensen Huang and allegations concerning a possible foreign intelligence operation. Nvidia’s board was reportedly examining whether Huang had been targeted.
A separate media report alleged that the situation facilitated at least $7.5 billion in chip shipments to China. Nvidia shares declined 1.4% in premarket trading after falling 4.3% on Monday. The company is scheduled to report earnings next week.
Outlook: Inflation and Monetary Policy Set the Market Direction
The latest inflation reading has complicated the outlook for global equities by strengthening expectations of further Federal Reserve tightening at a time when investors are already reassessing technology valuations and geopolitical risks.
Markets will remain sensitive to incoming inflation data, Federal Reserve commentary and corporate earnings, particularly across the AI infrastructure sector. Meanwhile, developments surrounding US-Iran relations and declining oil prices could provide some relief to energy-related inflation pressures.
The interaction between monetary policy expectations, AI investment returns and geopolitical developments will remain central to market direction as investors determine whether the recent equity rebound can withstand renewed pressure from higher interest rates.
