As investors usher in a new month and the second quarter, Asian markets are set for a week of pivotal economic releases.

Key events include the Reserve Bank of Australia's interest rate decision, inflation releases from South Korea, the Philippines, and Thailand, and a series of manufacturing PMIs.

Beyond regional data, investors will also monitor US President Trump's anticipated "all countries" tariff announcement on Wednesday.

Here's a breakdown of the key events to watch this week.

MONDAY, March 31

South Korea's industrial production rebounded with a 7% year-on-year growth in February, compared to a 4.7% decline in January, according to official data.

Retail sales also recovered, rising 1.5% month-on-month in February from a 0.7% fall in January.

On the other hand, Japan's industrial output expansion sharply slowed to 0.3% YoY in February from 2.2% in the first month of 2025.

Retail sales growth also weakened to 1.4% YoY in February from 4.4% in January.

China, the biggest economy in Asia, released its official March PMI data.

The NBS Manufacturing PMI came in at 50.5, in line with market estimates and up from 50.2 in the previous month, denoting an increase in factory activity.

Meanwhile, retail sales declined in Thailand and Hong Kong. Thailand posted a 1% drop in January, while Hong Kong saw a 15% slump in February.

TUESDAY, April 1

The Reserve Bank of Australia's interest rate decision will take center stage on Tuesday.

The nation's big four banks-ANZ, Commonwealth Bank, NAB, and Westpac-expect no change in the cash rate following a reduction in February.

Set by the RBA, the cash rate target influences how much commercial banks charge customers for borrowing money.

Meanwhile, the country's retail sales will also be out.

"We expect retail trade will record a small positive lift of 0.2% in February, following a rise of 0.3% in January," CommBank Research said in a note.

Also of interest will be the March manufacturing PMIs of the Philippines, South Korea, Taiwan, Thailand, and Vietnam, plus the Bank of Japan's Tankan business sentiment index.

The quarterly tankan survey is likely to show that sentiment among Japanese companies deteriorated amid fears of higher US tariffs, according to The Wall Street Journal.

Other noteworthy data due Tuesday are Japan's unemployment figures and South Korea's trade numbers.

Economists surveyed by WSJ predict that Korea's exports likely grew 1.7% in March from a year earlier, following a revised 0.7% gain in February.

WEDNESDAY, April 2

South Korea's annual inflation rate for March likely held steady at 2%, according to Trading Economics.

On a month-over-month basis, the March inflation rate may have eased to 0.2% from February's 0.3%, consensus estimates show.

Midweek will also see the release of manufacturing PMI readings for Indonesia and Malaysia, along with the Philippines' producer prices.

THURSDAY, April 3

The Bangko Sentral ng Pilipinas has delayed its monetary policy stance review, now set to take place on April 10 instead of the originally scheduled April 3. No reason for the delay was given.

The development comes after the BSP kept the benchmark rate at 5.75% during its February meeting, which defied market expectations.

Rather than a rate cut, the BSP significantly lowered the reserve requirement ratio, freeing up over 300 billion Philippine pesos in loanable bank funds to stimulate the economy.

Other key data due Thursday are the private sector activity of Hong Kong and Singapore, the China Caixin services and composite PMIs, and Australia's trade figures.

FRIDAY, April 4

The economic calendar for Friday features the release of March inflation data from the Philippines and Thailand, alongside Singapore's retail sales for February.

SUNDAY, April 6

Vietnam will publish a flurry of indicators, including its economic growth rate for the first quarter, plus trade balance, inflation data, retail sales, and tourist arrivals for the month of March.
