The US economy is facing heightened tension as the Consumer Price Index reached 3.4% year-on-year for August. This figure, aligning with analyst projections, points to persistent inflation that shows no signs of abating despite monetary pressure. At the same time, core inflation—which excludes volatile food and energy sectors—slipped slightly to 2.4%. However, this apparent stability masks a more complex reality, largely driven by surging energy costs, with fuel accounting for a third of the overall monthly increase.

Markets are reacting with palpable nervousness, as the odds of a policy rate hike by the Federal Reserve at its next meeting have jumped above 80%. This expectation reflects investors' conviction that the US central bank will have no choice but to tighten monetary policy to counter inflation that remains stubbornly far from its historic 2% target. Yields on two-year government bonds, a metric particularly sensitive to monetary policy shifts, rose in response to the data.

A key challenge lies in the lag inherent in the published statistics: these figures reflect the situation in August and do not account for the recent surge in oil prices, with crude crossing the symbolic $100 per barrel mark. This leaves the monetary policy committee facing a tough dilemma. While some officials favor a cautious approach grounded in the slight decline in core inflation, Fed leadership appears more inclined toward firm action, viewing current progress as insufficient to guarantee lasting price stability.

For financial markets, and particularly for risk assets such as crypto-assets, this environment creates unprecedented conditions. Given that a rate hike is now largely priced in by market participants, a monetary tightening decision could prove less disruptive than keeping rates unchanged, which would catch the current consensus off guard. As the official decision nears, analysts are parsing every signal, well aware that the US economy is navigating between buoyant consumer spending, particularly in the travel sector, and the growing threat of a fresh global energy shock.
