The final quarter of the year begins with bond markets unsettled by geopolitical tensions, fiscal concerns and heavy investment in artificial intelligence. Global borrowing costs have climbed to their highest levels since the 2007-08 financial crisis, even as major stock indexes remain close to record highs.

September's US nonfarm payrolls report, due Friday, is the week's key economic release. Economists expect the US economy to have added around 100,000 jobs, with the unemployment rate forecast at 4.2%. The data will be closely watched for clues on the Federal Reserve's next rate move.

The US Personal Consumption Expenditures price index, due Wednesday, will provide fresh insight into inflation pressures and progress toward the Federal Reserve's 2% target. Eurozone inflation data are also due Friday, while Tokyo's inflation figures will offer a closely watched gauge of Japanese price pressures.

A renewed rise in energy prices is raising questions about whether inflation pressures could spread through wages and living costs. Markets are already pricing a faster global tightening cycle than they did only weeks ago, while 10-year US Treasury yields have moved above 5%.

Micron Technology reports earnings after the US market close on Wednesday. The memory-chip maker has benefited from surging spending on AI data centres, with its shares gaining sharply this year. But the stock has fallen during the quarter as investors question the sustainability of AI infrastructure spending. Strong guidance could ease concerns, while weaker forecasts could add to doubts over the durability of the AI boom.

The Reserve Bank of Australia is expected to raise interest rates by 25 basis points on Tuesday, taking its cash rate to 4.6%, according to market expectations. The move comes despite falling house prices and an unexpected rise in unemployment. Core inflation remains above the RBA's 2%-3% target range, while higher oil prices add another challenge.

Investors enter Q4 facing a packed calendar of economic and political risks. US employment and inflation data will shape expectations for the Federal Reserve, while energy prices and global bond yields remain key market variables. Corporate earnings, particularly from AI-linked companies, will provide another test for stretched market valuations.
