Louis Vuitton, the world's biggest luxury brand, last February led the way to a string of price hikes from some of the industry's biggest names.

Riding a wave of soaring demand fuelled by shoppers drawing on savings from pandemic lockdowns, high-end labels have been raising prices over the past few years, with Birkin bag maker Hermes flagging plans to hike prices by 5% to 10% this year, to cope with rising costs and currency fluctuations.

Bloggers on China's social media platform Xiaohongshu are forecasting price increases at Louis Vuitton of between 8% and 20% on Feb. 18, and chatter has focused on lines forming outside of stores in Shanghai, for example, seen as a sign shoppers are seeking to make purchases before any increase.

Users of the Xiaohongshu site, known in the industry as Little Red Book, often cite sales associates for the fashion labels and have a track record of correctly predicting price increases but do not always specify their sources.

LVMH executives last month signalled limited price hikes, mainly for leather goods, to reduce price gaps between the Unites States and Europe.

"From time to time we have the possibility of doing it," LVMH chief financial officer Jean-Jacques Guiony told reporters at a company results presentation last month, noting executives have a prudent approach to price hikes, and seek to avoid multiple increases.

Louis Vuitton, which sells a popular tote bag called Neverfull for 1,500 euros ($1,609.35), raised prices in France by around 3% to 7% this month, according to website PurseBop.

The website, which tracks the luxury market, cited models of the top handle Capucines bag that went up to 5,500 euros from 5,150 euros and a Pochette Accessoires purse that rose to 1,050 euros from 980 euros.

LVMH and Louis Vuitton did not immediately reply to a request for comment.
