THE tide of global stimulus is swelling as China cut interest rates and India launched an expansionary budget over the weekend, even as a mixed bag of manufacturing surveys underlined the challenges facing the region.

The Reserve Bank of Australia (RBA) holds its March policy meeting on Tuesday and there is a real chance it will cut rates for a second time in as many months.

Investors seemed encouraged enough by all this policy action to nudge most share markets higher while giving a fillip to commodities such as copper.

Cuts to benchmark lending and deposit rates announced by the People's Bank of China (PBOC) on Saturday evening pre-empted official data showing a second consecutive month of shrinking manufacturing activity (PMI).

There was better news from the private HSBC/Markit version of the PMI on Monday, which climbed to a sevenmonth top of 50.7 in February, from 49.7 in January, as new orders picked up.

But it also showed China's manufacturers were struggling to cope with erratic export demand and deflationary pressures. Thus, analysts suspect the PBOC's easing, its third major policy move since late November, will not be the last.

"The priority has been shifted to safeguard growth," wrote analysts at OCBC Bank. "We still expect one more interest rate cut in the second quarter and the next possible move is likely to be a reserve requirement ratio cut."

They also saw scope for fiscal policy to play a part with government spending likely to pick up after the National People's Congress meeting this week.

Over the weekend, India's reform-minded prime minister, Narendra Modi, released a budget that pleased economists and investors with pledges to spend more on modernising ageing roads and railways while keeping borrowing in check.

Ratings agency Moody’s judged that the budget prioritised growth over deficit reduction.

"Recent policy announcements, including the budget, support Moody's expectation that India's growth will remain stronger than the global average, and more robust than the median for similarly rated sovereigns," the agency concluded. The February HSBC PMI for India dipped to a five-month low in but at 52.9 still pointed to solid growth in the sector.

Japan's Markit/JMMA PMI faded a little to a final 51.6 in February, from January's 52.2 in January, but new export orders rose for the eighth straight month in a promising sign.
