Portugal Colonial - Seoul stocks sink amid S. Korea drama as Asian markets mixed

The shock announcement sent shivers through the trading floor in Seoul and fuelled a political crisis in Asia's third-biggest economy, with the opposition party saying it had submitted a motion to impeach Yoon.

Investors are now keeping a close eye on developments in the country, with analysts pointing out that the upheaval comes as authorities steeled for the second US presidency of Donald Trump who has vowed to reignite his hardball trade policy.

The Kospi index ended down more than one percent, having shed as much as 2.3 percent at the open, as traders fretted over the impact of Yoon declaring South Korea's first martial law in more than four decades.

He said the decision was made "to safeguard a liberal South Korea from the threats posed by North Korea's communist forces and to eliminate anti-state elements plundering people's freedom and happiness".

However, he backed down hours later when lawmakers voted to oppose the declaration, while thousands of protesters took to the streets and the nation's largest umbrella labour union called an "indefinite general strike" until Yoon resigned.

The won tumbled more than three percent to a two-year low of 1,444 per dollar after the declaration, then bounced back to around 1,410 following the U-turn.

"Rarely does a combined sell-off in a country's stocks, bonds, and currency feel like a relief rally," said Thomas Mathews, head of Asia-Pacific markets at Capital Economics.

Mathews said the situation could have been "much worse" had the president not aborted his plan.

"Investors now 'only' have to worry about a period of significant political uncertainty," he said.

The South Korean finance ministry and central bank looked to provide stability and reassure markets.

"As announced together with the government, it has been decided to temporarily supply sufficient liquidity until the financial and foreign exchange markets stabilise," the Bank of Korea said.

It added that "the range of securities eligible for (repo) transactions and the target institutions will be expanded".

Deputy Prime Minister Choi Sang-mok, who also holds the economy portfolio, said financial authorities will keep international partners informed about developments.

But Michael Wan at MUFG warned of remaining uncertainty, despite the measures to recover from the initial economic hit.

"From a macro perspective, South Korea was already one of the more vulnerable countries to the impact of Trump's proposed tariffs," he said in a commentary.

"This recent development could raise some further risk premium on the currency at least until we get clarity on political stability," he added.

The losses in Seoul came on a mixed day for Asia markets, with Tokyo, Hong Kong, Singapore, Taipei, Mumbai, Bangkok and Jakarta rising but Shanghai, Sydney, Wellington and Manila falling.

Wall Street had provided a healthy lead, with the S&P 500 and Nasdaq hitting fresh records as investors try to assess the chances of the Federal Reserve slashing interest rates again this month.

Meanwhile, Germany's DAX ended above 20,000 for the first time.

Even Paris eked out gains despite the brewing political crisis in France, where opposition lawmakers vowed to topple the three-month-old minority government of Prime Minister Michel Barnier in a no-confidence vote owing to a budget standoff.

The euro remained wedged close to a 14-month low of around $1.0500 on concerns about the outlook for the eurozone's number two economy.

Oil prices extended gains after surging around 2.5 percent Tuesday on reports that major producers at the OPEC+ grouping were close to a deal to extend output limits.
