Global Market Today: Asian stocks waver as oil gains fuel inflation, rate concerns

Asian stocks fluctuated amid rising oil prices and stronger-than-expected US economic data, which raised inflation concerns and speculation of additional interest-rate increases. Japanese, Australian, and New Zealand government bonds trailed US Treasuries in their declines. The yield for five-year US notes surpassed 5% for the first time since 2007.

The 10-year yield increased by 15 basis points to 5.11%, marking the largest single-day rise since the market shocks caused by President Donald Trump's April 2025 tariff announcement. Brent crude remained in the $102.84 range, up almost 4% from the previous day. The US dollar index climbed to its highest level since late July, while gold approached a one-week low due to higher interest rates diminishing its allure.

Asian equities fell by 0.3%, while Japanese stocks marginally rose following the reopening of Tokyo markets after a three-day holiday. The likelihood of persistent high energy costs and a robust US economy could maintain pressure on bonds and stocks, prompting investors to re-evaluate the extent of potential Federal Reserve policy tightening.

Speculation on further rate hikes surged after the Fed raised rates for the first time since 2023. Tony Miano of Wells Fargo Investment Institute noted the market signaling the onset of a genuine tightening cycle, with significant reprioritization of discount rates affecting equities, mortgage and corporate borrowing costs, and risk assets.

Traders also scrutinized geopolitical tensions, such as Iran's rejection of freedom of navigation in the Strait of Hormuz despite ongoing sanctions and a US blockade. US diesel futures surged as the Trump administration collaborated with refiners to voluntarily limit exports, an alternative to a full embargo. Meanwhile, US mortgage rates hit a two-year high, and the S&P Global flash US composite purchasing managers index rose in September to its highest level since July 2021, indicating accelerated business activity growth.

The Federal Reserve had increased borrowing costs last week to between 3.75% and 4%, a decision Fed Chair Kevin Warsh described as introducing a "dose of accommodation." Fed Governor Michael Barr suggested additional rate hikes might be necessary to bring inflation back to the central bank's 2% objective. Swaps now indicate three quarter-point rate hikes expected over the next year, with a substantial hedge for a fourth.

This would push the Federal Reserve's target rate to a range of 4.75% to 5%. Experts warned against rushing into investments, emphasizing the need to navigate the current market volatility.
