India's response to the price spike was to remove tariffs on imported raw sugar and tighten inventory limits for large buyers.
Shares of sugar producers fell on Friday in response, dragging down a Bloomberg index that tracks 15 sugar companies.
That drop matters because the run-up before it was huge. Friday's slide barely dented the bigger picture.
The rally happened for a real reason. Sugar supply tightened after lower output and cane being diverted to make ethanol, which is used in fuel. With less sugar available, prices shot up in India, the world's second-biggest sugar producer.
This year's squeeze follows a long stretch of weak prices. For nearly three years, mills sold sugar at prices that did not cover their production costs, squeezing profits and forcing some to delay payments to cane farmers. The recent surge, driven by lower output and greater ethanol diversion, has flipped the industry's fortunes, but it has also drawn the government's attention.

The government's intervention is the kind of thing sugar investors have learned to watch carefully. As one market watcher put it, "This is a policy-sensitive sector, and when policymakers act, the market listens."
One analyst described the current situation as "a meaningful tightening in the domestic demand-supply balance." In plain terms, supply is short and demand is strong. That is usually good for prices.
The government measures may cap how much further sugar stocks can climb. But there are reasons to think the good times are not over. Producers are getting strong prices for their sugar, known as realizations.
Inventories are low. And the upcoming festival season typically boosts demand for sweets.
Another analyst pointed out that "mills are sitting on inventories whose value has risen sharply after the recent price surge." That means the sugar they already have stored is worth a lot more now than it was a few weeks ago.
The picture here is more balanced than the Friday selloff suggests. A third analyst put it plainly: "The fundamentals here are actually quite robust."
Some producers are seeing record prices for sugar leaving their mills after nearly three years of selling below what it cost them to make it. That is a big swing. For three years, these companies were bleeding money. Now they are finally making some.
The government's move is a reminder that when prices climb too fast, policymakers tend to step in. That is not a reason to panic, but it is worth understanding. The same forces that pushed prices up are still there, and the festival season could keep demand strong.
For investors, the key takeaway is that this sector now has two forces pulling in different directions. Government policy is trying to push prices down, while supply shortages and seasonal demand are pushing them up. Which one wins will determine whether the rally resumes or fades.
