Divergence des marchés émergents : fragilité de l'Asie de l'Est contre force des ressources

Regional Equity Bifurcation

Emerging market sentiment is currently defined by a sharp divide between East Asian equity markets and other regional players. On October 2, 2026, the Hang Seng experienced a significant contraction, closing -2.6% from its previous close [13]. This move was noted as being far outside the index's normal trading range [13]. The volatility extended into the Hang Seng Tech Index, which fell 2.45% [13]. Specific sectors also faced extreme pressure; for instance, the "physical AI" stock Huanchuang Technology saw its market value shrink to 11.5 billion HKD following a midday drop of over 44%, despite a previous first-day listing surge of 265.68% [13].

While East Asian markets face downward pressure, Brazil has shown a contrasting trend. On the same day, the Bovespa closed +1.6%, a move also described as being significantly outside its normal range [13]. This indicates a supported appetite for Brazilian assets even as rapid selling occurs in China and Hong Kong [13]. However, the sharp declines in Hong Kong often spill into other regional markets within a day or two, suggesting that the current fragility in East Asia could pose a broader risk to emerging market sentiment [13].

China’s Consumer and Industrial Contradictions

The data regarding China presents a complex picture of consumer fragility alongside industrial and energy-related progress. In the consumer sector, Nike reported a 26% plunge in its China sales [20]. Additionally, BYD faced selling pressure, with its stock recording a -2.29% loss on October 2, 2026 [15]. Despite these equity market pressures, there are signs of localized consumer activity; China's National Day holiday box office, including pre-sales, surpassed 200 million yuan as of the evening of October 1 [13].

On the industrial and energy front, China is making significant infrastructure strides. A high-altitude ultra-supercritical coal-fired power project, a 2×660MW facility in Qinghai, successfully connected its first unit to the grid on October 2, 2026 [8]. These types of coal-fired projects are being utilized to provide peak-shaving support for the integration of wind and solar energy [8]. Furthermore, significant gas reserves exceeding 100 billion cubic meters have been identified in the Ordos Basin [5].

Global Energy and Inflationary Pressures

Macroeconomic headwinds, particularly regarding energy and inflation, are adding layers of volatility to the emerging market landscape. In the Eurozone, inflation rose to 3.8% in September, the highest level in three years, driven largely by an 18.8% year-on-year increase in energy prices [13]. This is compounded by geopolitical instability, including a US-Iran war that has caused US diesel prices to surge 70%, reaching $6.38 per gallon [13].

Energy markets are also reacting to geopolitical friction in the Middle East. Brent crude is trading at $102.28 per barrel, even as it heads toward weekly losses of approximately 2% [13]. The risk of conflict in the Persian Gulf is heightened by the deployment of a third US aircraft carrier strike group and nearly 10,000 soldiers to the Middle East, alongside the deployment of Patriot missile systems to Saudi Arabia and Qatar [13]. These tensions, combined with the decision by Chinese refineries to suspend petroleum product exports (excluding Hong Kong) for October, create a volatile environment for global energy supplies [13].

Regulatory and Fiscal Signposts

In other emerging markets, political and regulatory shifts are driving localized volatility. In Brazil, the betting sector is facing significant uncertainty following President Lula da Silva's decree banning regulated online betting on September 25 [13]. This move led to a 74% increase in illegal iGaming operators within 24 hours [13]. The ultimate direction of this sector may depend on a potential Congress vote or the results of the October 4 presidential election [13].

In India, the government is weighing fiscal adjustments to manage food prices. Specifically, officials are considering reducing import duties on pulses, such as the current 10% duty on masoor and chana, and the 30% duty on yellow peas, following uneven monsoon rainfall [13]. Meanwhile, the progress of the India-US trade deal remains uncertain, with US Trade Representative Jamieson Greer noting that while discussions are constructive, a deal is not imminent [13].

What to watch

• The continued price action of the Hang Seng and whether the -2.6% drop triggers a wider regional sell-off.
• The outcome of the Brazilian presidential election on October 4 and the potential second round on October 25.
• The completion of the dual 660MW units in Qinghai by the end of 2026.
• The US Congressional elections on November 3 and the potential implementation of US diesel export restrictions.
• The trajectory of China's National Day holiday consumption through October 7.
• The final decision from the Indian government regarding import duty reductions on pulses.
