LVMH Moët Hennessy Louis Vuitton SE, the behemoth of luxury, has posted stellar first-half 2018 results. Double-digit growth across nearly all business groups and geographies, record margins, and a free cash flow exceeding €2 billion - a financial performance worthy of a standing ovation. But amidst the celebratory clinking of champagne glasses, a subtle note of caution emerges, whispered by CFO Jean-Jacques Guiony: the potential volatility of the renminbi.

This concern, seemingly buried under a mountain of positive news, might hold the key to LVMH's future performance, especially in light of the company's aggressive hedging strategy. While LVMH meticulously hedges against currency fluctuations, a dramatic renminbi devaluation, reminiscent of the 2015 turmoil, could unleash a financial storm that even the most meticulous hedging might struggle to contain.

This potential risk stems from LVMH's significant exposure to the Chinese market. Asia, excluding Japan, now accounts for over 30% of total group sales, with China being the primary driver. The Chinese consumer's appetite for luxury is undeniable, reflected in the double-digit growth of Hennessy depletions and Louis Vuitton's stable 20% growth in Chinese demand across both Q1 and Q2. But this reliance on a single market, particularly one experiencing currency volatility and potential economic headwinds, could create a vulnerability that investors shouldn't ignore.

Hypothetical Scenario: Impact of Renminbi Devaluation

Here's the hypothesis: LVMH's heavy reliance on a single-market hedging strategy could backfire if the renminbi deviates significantly from its hedged rate. While a strong hedging policy shields the company from moderate fluctuations, a sharp devaluation exceeding the hedged rate could expose LVMH to substantial losses, potentially impacting margins and profitability.

Let's crunch some numbers. Guiony revealed that LVMH has hedged 65% of its 2019 budget at a rate of $1.23 for the dollar and JPY 131 for the yen. The current dollar rate sits significantly above this hedged rate. This suggests a comfortable margin of safety. However, the renminbi hedging rate remains undisclosed.

What if the renminbi depreciates by 10%, exceeding the hedged rate by 5%? Considering Asia's contribution of over 30% to total sales, even with a 65% hedge, LVMH could face a 1.65% (30% x (10%-5%) x 35%) negative impact on revenue. This impact could be magnified on the bottom line, depending on the cost structure in the Asian region.

While this hypothetical scenario might seem extreme, it underscores the potential vulnerability of LVMH's hedging strategy to extreme currency movements. The 2015 renminbi devaluation sent shockwaves through the global economy, demonstrating that dramatic currency shifts are not merely theoretical possibilities.

Further amplifying the risk is LVMH's inherent reliance on pricing power to maintain its aura of luxury and exclusivity. In 2018, Louis Vuitton strategically reduced prices by 4% in China, reflecting lower import duties. This move, while aimed at ensuring fairness and maintaining price alignment, could limit the company's ability to adjust prices upward in response to a significant renminbi devaluation.

Adding another layer of complexity is the potential impact of escalating global trade tensions. While the luxury sector might not be the primary target of tariff wars, a slowdown in global trade could dampen consumer confidence and spending, potentially impacting even high-end luxury consumption.

LVMH's first-half performance is undeniably impressive. Yet, beneath the surface of success lies a hidden risk, a currency time bomb that could explode if the renminbi takes an unexpected turn. While LVMH's hedging strategy provides a safety net, its efficacy against extreme currency movements remains untested. Investors, while applauding the company's current success, should keep a watchful eye on this potential risk, ensuring that the celebratory champagne doesn't mask a brewing financial storm.
