American consumers, once hit by the international financial crisis, have re entered the market.

Over the past year, luxury sales in the US market have increased by 12%, and Asian markets have increased by 22%. China is still the fastest growing luxury market.

In addition, Chinese tourists buy large quantities of brand-name goods while traveling around Asia. Consumption in Europe, the United States and other regions boosts local luxury sales growth.

Bain's report predicts that the total sales of tax-free luxury goods on duty free shops and aircraft will reach 16 billion euros this year, while the trend of luxury tourism for Chinese consumers is strengthening.

The share prices of the largest luxury goods companies have risen sharply this year as sales are stronger than expected. The share prices of Louis Vuitton Hennessy, Swatch, historic peak and Hermes have risen by more than 50% in the past 12 months.
