Thursday's trading session has been dominated by a sharp rebound in crude oil prices, triggering another wave of sell-offs across both equities and government bonds. Investors are once again focusing on escalating geopolitical risks and their inflationary repercussions.
Commodities
Brent crude is gaining over 4% today, breaking above $104 per barrel. WTI crude is recording a similar scale of advance, reaching nearly $92. The immediate catalyst behind the movement stems from reports challenging the previous assumption that the Donald Trump administration would refrain from escalating the conflict with Iran until the November mid-term elections.

Tensions are further exacerbated by renewed Houthi attacks; over the past two days, rebels struck two Saudi airports (in Riyadh and Abha), killing three people and injuring dozens more. Adding to supply-side risks is Hurricane Isaias, the first of the Atlantic season, which forced Gulf of Mexico producers to shut in approximately a quarter of crude oil output and around 16% of natural gas production. The storm is expected to intensify further, making landfall on the Louisiana and Texas coasts between Friday evening and Saturday.
Debt Market
Rising oil prices are feeding concerns over persistent inflation, driving a continued sell-off in sovereign bonds. The yield on US 10-year Treasuries is up around 5 bps to 5.35%. An even more dynamic movement is visible in French government bonds (+9 bps to 4.95%), a topic addressed in greater detail in yesterday's equity commentary.

Notably, as much as 38% of the entire pool of French high-grade corporate debt is currently trading at a lower yield than comparable government securities (compared to just €12 billion at the start of 2026). Investors view companies with robust, international revenue exposure, such as L'Oréal or TotalEnergies, as a safer haven than the French sovereign.

Equity Market
The sell-off across oil and bond markets is spilling over into equities. Futures on the S&P 500 are down 0.4%, signalling a second consecutive day of retreat from record highs. European indices are also trading firmly in the red. The pan-European Euro Stoxx 50 is down 1.1%, the French CAC 40 has lost 0.9%, the Italian FTSE MIB is down 1.3%, whilst Germany's DAX is trading 0.8% lower.

The European banking sector is coming under particularly intense pressure, with the Stoxx 600 Banks Index down by nearly 2%. Concerns surrounding France's fiscal position are weighing on sentiment, potentially dissuading the ECB from embarking on an aggressive interest rate hiking cycle that markets had previously priced in.

Semiconductor stocks are also underperforming, with Samsung's quarterly results taking centre stage. Despite reporting a tenfold surge in operating profit, the figures failed to satisfy investor expectations, causing its share price to slide by almost 2.5%. Samsung's preliminary Q3 operating profit surpassed 100 trillion South Korean won for the first time (reaching KRW 107.4 trillion, or approximately USD 80 billion). Revenue rose to KRW 195 trillion, driven primarily by demand for HBM and DRAM memory chips.
Monetary Policy
One of the FOMC's most vocal policymakers recently, Christopher Waller, remarked today that further interest rate increases will likely be necessary to bring inflation back down to target. However, he noted that the central bank retains flexibility regarding the timing and does not need to tighten policy at an aggressive pace with rate hikes at every consecutive meeting. Markets are fully pricing in a rate increase in December, whilst attributing a probability of under 20% to a move at the upcoming meeting in late October.
Precious Metals and Cryptocurrencies
Gold is gaining around 0.3% today, climbing to approximately $4,120 per ounce, slightly above yesterday's 9-week low. Prices are supported by inflation concerns linked to surging oil prices, as well as the return of Chinese buyers following the Golden Week holiday. However, the recovery faces headwinds from a firmer US dollar, with the dollar index hovering near its year-to-date highs. Gold remains roughly one-fifth cheaper than prior to the outbreak of the US-Iran conflict. Silver is shedding about 1.4% today, whilst Bitcoin edges down by around 0.4%.
