(Sharecast News) - Most Asia-Pacific markets saw declines on Wednesday, following a downturn on Wall Street overnight, spurred by hotter-than-expected US inflation data.

Patrick Munnelly, market analyst at TickMill, said most Asian equity indices were trading in negative territory, reflecting the downturn seen in the US overnight.

"The significant change in Federal Reserve expectations, first triggered by a strong US jobs report and then reinforced by Tuesday's unexpected increase in inflation, has led to a decrease in market expectations for 2024 interest rate cuts from approximately 160 basis points at the end of last year to just under 90 basis points currently," he said.

"This shift has had a ripple effect globally, with traders now anticipating only one interest rate cut from the Reserve Bank of Australia this year, compared to the previous expectation of two cuts.

"Furthermore, the anticipation of higher US interest rates for a longer period is expected to constrain the potential for central banks in emerging markets to implement easing measures, especially those that had previously raised rates in an attempt to stabilise their currencies against a strengthening dollar."

In Japan, the Nikkei 225 dropped by 0.69% to 37,703.32, while the Topix fell by 1.05% to 2,584.59.

Japanese bond yields rise as yen weakens

In economic news, 10-year Japanese government bond yields rose to 0.766 on Wednesday, marking their highest level since 11 December.

The increase coincided with the yen's seventh consecutive session of weakening, slipping below the 150 mark against the dollar.

Under the Bank of Japan's yield curve control policy, the central bank maintained a target of around 0% for 10-year bond yields, with an upper limit set at 1% as a reference.
