Key data points show the Producer Price Index (PPI), which measures wholesale costs, fell 0.3% month-over-month in June, against market expectations for it to remain flat.

The core PPI, which excludes food and energy, rose 0.2% month-over-month, slightly below expectations. The core PPI excluding trade services increased by just 0.1%.

Inflation data has delivered positive signals for two consecutive days. The previous day's Consumer Price Index (CPI) unexpectedly fell sharply by 0.4%, with both rounds of data improvement primarily driven by lower energy prices.

Data released by the US Bureau of Labor Statistics on Wednesday indicated that, driven by falling energy costs, wholesale prices unexpectedly declined in June, showing signs of easing inflationary pressures.

After seasonal adjustments, the final demand Producer Price Index (PPI) for the month decreased by 0.3% compared to the previous month. The Dow Jones consensus had expected the indicator to remain unchanged. The PPI rose 5.5% year-over-year.

May's data was significantly revised downward. The initial reading showed a 1.1% month-over-month increase, which was later revised to only a 0.6% gain.

The core PPI, which excludes food and energy, rose 0.2% month-over-month, while the market had anticipated a 0.3% increase. The core PPI excluding trade services rose 0.1% month-over-month and 5.1% year-over-year.

In line with the trend in consumer prices, the improvement in wholesale prices was mainly supported by cooling energy prices. A brief easing of tensions between the US and Iran put downward pressure on international oil prices.

Prices for goods fell sharply by 1.4% month-over-month, the largest decline since July 2022. Within this category, energy prices plummeted 6.4%, while final demand food prices dropped 0.6%.

Within the goods sector, gasoline prices fell sharply by 12% month-over-month, contributing to two-thirds of the total PPI decline for the month.

Meanwhile, service prices rose 0.2% month-over-month, driven by a 0.4% increase in trade services prices.

This data was released one day after the Bureau of Labor Statistics published the Consumer Price Index (CPI). The core measure of end-consumer inflation unexpectedly fell sharply by 0.4% month-over-month in June, with the annual inflation rate dropping to 3.5%, marking the largest single-month decline since April 2020 at the onset of the COVID-19 pandemic.

The core CPI remained flat month-over-month in June, with the annual rate falling to 2.6%.

Both inflation indicators remain well above the Federal Reserve's 2% policy target, but they also demonstrate that the central bank's five-year-long battle against inflation is making phased progress.

A chief economist noted, "The Federal Reserve's fight against inflation is far from over, but there is positive news from the front lines. Factory-level prices continue to fall, and the ability of businesses to pass on costs to downstream consumers is not as strong as previously expected. The probability of further Fed rate hikes will continue to decline."

US stocks rose in early trading on Wednesday as trading institutions lowered their expectations for rate hikes. According to the CME Group's FedWatch tool, the market currently sees a roughly 50/50 probability of a rate hike in September.

Both the CPI and PPI are important inputs for calculating the Federal Reserve's core inflation measures. Policymakers pay closest attention to the Personal Consumption Expenditures (PCE) price index, which will be released by the US Department of Commerce later this month.

In May, the headline PCE inflation was 4.1%, with core PCE at 3.4%. Given this week's price data, both indicators are highly likely to decline in tandem.

Markets are still betting that the Federal Reserve will raise interest rates within the year, with the earliest possibility being in September. The Federal Reserve Chair indicated to House lawmakers on Tuesday that the June price decline does not mean the inflation problem has been "mission accomplished."
