"Pan Gongsheng, the central bank governor, alongside the ministers of commerce and finance, as well as the new top securities regulator, will address the media.

"In parallel, Japan's largest bank anticipates the central bank's departure from negative interest rates within two weeks and is making necessary preparations."

Munnelly noted that Mitsubishi UFJ's assessment contrasted with the swap market's evaluation, which placed the likelihood of Bank of Japan governor Kazuo Ueda altering policy in March at about 50%.

"The 'Super Tuesday' primaries in the US suggest a forthcoming electoral rematch between Biden and Trump.

Australian economy experiences modest growth; South Korea inflation rises

In economic news, Australia's economy expanded 0.2% in the fourth quarter of 2023, marking a slowdown from previous quarters.

The growth, slightly below expectations, was primarily fueled by government spending and business investment, according to the Australian Bureau of Statistics.

For the full year, Australia's real GDP growth reached 1.5%.

"The Australian economy is at a cyclical low point, with policy settings and fast inflation curbing growth," said Sean Langcake, head of macroeconomic forecasting at Oxford Economics.

"Indeed, while growth has stayed in positive territory, it has slowed in each quarter over 2023 and contracted once again in per capita terms in the fourth quarter.

"But there are some positive signs in these data with productivity growth helping ease unit labour cost pressures, and household savings stabilising in the quarter."

In South Korea, inflation accelerated for the first time in three months, reaching 3.1% in February.

This exceeded January's 2.8% rate and market expectations.

Core inflation, which excludes volatile food and energy prices, also rose to 2.5%.
