Kweichow Moutai fell the most in nearly two years after the influential People’s Daily took aim at the high price of the liquor it makes, saying the alcohol was often used in corruption cases.

Moutai, China’s biggest domestically listed company, tumbled 7.9% in its worst decline since October 2018, wiping out a record $25bn of value. Moutai’s products are often involved in the country’s official corruption cases and used for bribery given their high prices, according to a commentary carried by a WeChat account owned by the People’s Daily.

“Alcohol is meant for drinking, not for speculation or corruption,” the People’s Daily commentary said.

The plunge reverberated across China’s almost $10-trillion stock market, with the SSE 50 index of the nation’s largest companies sinking 4.6%, its worst decline since early February. Other liquor makers also plummeted, with Wuliangye Yibin, Jiangsu Yanghe Brewery Joint-Stock and Luzhou Laojiao all falling by the 10% daily limit.

The comments were seen as the latest efforts by officials to cool sentiment in the nation’s equities after retail investors took on the most amount of leverage in five years to speculate in shares. Targeting Moutai, one the most popular stocks in the country, is also a tried and tested strategy: in 2017, Xinhua News Agency said the stock was rising too fast, triggering a wider sell-off.

“Both Moutai shares and its products are hot investment targets, and cracking down on them signals the regulators’ determination to remove froth from the A-share market,” said Zhang Gang, a strategist at Central China Securities. “Moutai is such a heavyweight and if this bubble keeps building, the aftermath will be terrible if it burst. Policymakers don’t want to repeat the history of 2015.”

A leverage-fueled bubble five years ago wiped out $5-trillion of capitalisation, burnt retail investors and shook confidence in regulatory oversight of the stock market. Officials started taking measures to calm the current rally at the end of last week after the SSE 50 neared its 2015 high, with government-owned funds announcing plans to trim holdings of stocks that had soared.

Targeting Moutai was a bold step. The distiller had a market value of $320bn at its peak on Monday, making it one of the world’s largest companies. The shares had surged almost 50% this year before Thursday’s plunge, after doubling in 2019.

Investors have been encouraged by Moutai’s ability to keep raising retail prices for its products, which can take as long as five years to distil.

The company has found itself in official sights before. Back in 2013, the stock plunged when Chinese President Xi Jinping came to power and clamped down on lavish spending by party cadres.
