The recent downturn in US luxury spending, as evidenced by Citi's credit card data, signals a significant shift in consumer behavior among affluent Americans. This trend is particularly noteworthy because the US market has been a crucial pillar of support for global luxury brands, many of which have faced headwinds in other key regions like China. The sustained decline, now spanning three consecutive months, suggests that even the most resilient consumer segment is becoming susceptible to broader economic anxieties. This caution is not merely a minor blip but rather a potential indicator of deeper economic currents at play, challenging the long-held assumption of an "unlimited source of growth" from wealthy US consumers.

Citi

Citi's analysis, based on millions of credit card transactions, provides a granular view into the spending habits of affluent US consumers. The data reveals a 6% year-on-year decline in overall luxury credit card purchases in September, following 4% drops in both July and August. This consistent downward trajectory offers a robust, real-time indicator of shifting sentiment, moving beyond anecdotal evidence to present a quantitative measure of the market's health.

The detailed breakdown from Citi also highlights a mixed picture across different luxury categories. While spending on leather goods and ready-to-wear items showed sequential improvement, the watches and luxury jewelry segments experienced further deterioration. This nuanced performance suggests that consumers might be prioritizing certain types of luxury purchases or reacting differently to price increases implemented by brands across various product lines.

September

The September data point is critical as it solidifies a trend rather than representing an isolated incident. A third consecutive month of decline underscores a growing pattern of caution among wealthy shoppers, moving beyond initial hesitations to a more entrenched behavioral shift. This period coincides with heightened economic uncertainty and the lead-up to the US midterm elections, factors often associated with reduced consumer and business spending.

Furthermore, the timing in September is significant because luxury brands had been relying on the US market to compensate for prolonged weakness in other major markets, particularly China. The continued softness in the US, therefore, removes a key buffer, making it harder for these companies to achieve the recovery investors have been anticipating. The broader economic indicators, such as rising US Treasury yields and mortgage rates, further contribute to the cautious environment observed during this month.

LVMH

The upcoming earnings season will be crucial in validating the extent of this weakness, with LVMH's third-quarter sales report on October 12 serving as a key bellwether for the entire luxury sector. As a conglomerate with a diverse portfolio of high-profile brands like Louis Vuitton and Tiffany, LVMH's performance often provides a reliable snapshot of the broader industry's health. Its results will offer insights into whether the observed spending slowdown is widespread or confined to specific segments.

Another significant indicator will come from Gucci owner Kering, which reports on October 22 and has already signaled expectations of a slowdown in the US market. These forward-looking statements from major players like LVMH and Kering suggest that the industry itself is bracing for a challenging period. The collective performance of these luxury giants will determine if the US consumer can still be considered a reliable engine for growth, or if a more fundamental recalibration of market expectations is necessary.
