San Francisco Frontiers - Equity markets struggle after more weak China data

The tepid start came on the year's last full week of trading, with the focus on key monetary policy decisions by the US Federal Reserve and the Bank of Japan.

Observers are also tracking developments in Seoul after South Korean lawmakers impeached President Yoon Suk Yeol at the weekend in the wake of his short-lived declaration of martial law this month.

Hong Kong and Shanghai sank after figures showed that Chinese retail sales grew 3.0 percent last month, much slower than October and well off the five percent forecast.

The figures highlighted the work leaders had in store as they try to kickstart consumption and reignite the world's number two economy.

Officials unveiled new promises at the weekend to boost the battered property sector and tweak monitoring of equity markets.

That came after investors were left unimpressed last week with Beijing's pledge to introduce measures aimed at "lifting consumption vigorously" as part of a stimulus drive.

President Xi Jinping and other key players said at the annual Central Economic Work Conference they would implement a "moderately loose" monetary policy, increase social financing and reduce interest rates "at the right time".

Lynn Song, ING's chief economist for Greater China, said in a commentary: "Household confidence clearly remains soft, and it remains to be seen if the 'vigorous support' for consumption promised next year will be effective in stimulating a recovery.

"We expect the rollout of supportive policies could take some time, but overall retail sales growth should recover in 2025."

Elsewhere in Asia, there were also losses in Sydney, Mumbai, Bangkok, Manila and Jakarta, though Singapore, Wellington and Taipei rose. Tokyo was flat.

London and Frankfurt opened lower, while Paris also retreated after French President Emmanuel Macron named centrist Francois Bayrou as prime minister on Friday as he looks to end months of political crisis.

Seoul fluctuated after Saturday's impeachment of Yoon, with South Korea's Constitutional Court starting proceedings Monday to determine whether to uphold the vote.

While the martial law crisis shocked markets, observers said the economic impact would likely be limited, with some suggesting a stimulus package could be implemented in the new year.

The Fed is widely expected to cut interest rates again Wednesday but there are fears it will have to slow its pace of easing next year owing to sticky inflation and bets that president-elect Donald Trump's tax cuts and tariffs will reignite prices.

The gathering comes after figures last week showed the consumer price index ticked up and wholesale prices accelerated.

Investors are now pricing in a more than 75 percent chance the Fed holds rates steady in January, according to the CME FedWatch tool.

The Bank of Japan is due to deliver its own policy decision after that, with debate swirling on whether officials will announce a third hike of the year, having moved in March for the first time since 2007 as price pressures continue to build.

"The Bank of Japan will likely tighten monetary policy on Thursday," said economists at Moody's Analytics, pointing to a 25 basis-point lift.

"The central bank is worried that yen weakness might spur inflation, hurting real wages and consumer spending."

But Tony Sycamore, an analyst at the IG trading group, said expectations were for officials to hold rates at 0.25 percent.

However, he added that "the central bank's current inaction is unlikely to persist, with any rate hold expected to come with strong forward guidance signalling a potential January hike".

"Broadening underlying pricing pressures, such as service prices, continue to point towards a more persistent inflationary trend. This environment suggests conditions are ripe for another rate hike, reinforcing expectations for tighter policy down the line."

On currency markets, the dollar rose against the yen.
