Inflation data next week could be the first to show impact of tariffs

Next week's inflation data releases (CPI and PPI) are expected to reflect the initial impact of higher tariffs on goods prices, potentially signaling an erosion of consumer spending power. While the market has largely shrugged off initial pricing pressures, a sustained rise in inflation could heighten concerns about an economic slowdown; however, investors remain optimistic that the US and China will continue negotiating duties. Separately, investors will be closely watching Apple's developer conference for features that could boost iPhone sales, and the NFIB small business survey for insights into the tariff impact on smaller businesses.

Analysis

The upcoming release of May's Consumer Price Index (CPI) and Producer Price Index (PPI) is keenly anticipated, as these figures are expected to provide the first clear indications of higher tariffs impacting goods inflation. Economists polled by FactSet project May's headline CPI to remain steady with a 0.2% month-over-month increase, while core CPI is forecast to accelerate to 0.3% month-over-month and rise to 2.9% year-over-year, up from 2.8%. Bernard Yaros, lead U.S. economist at Oxford Economics, suggests that May onwards is when the tariff impact on goods prices should become evident, potentially eroding consumer spending power and, if sustained, fueling concerns of an economic slowdown. Despite these inflationary headwinds and divergent economic signals—such as stronger-than-expected May payrolls contrasting with prolonged deterioration in consumer sentiment—the S&P 500 trades less than 3% below its all-time high. This market resilience is partly attributed to optimism that US-China trade negotiations will temper the most severe levies, and strong performance in 'Magnificent Seven' stocks, prompting strategists at Barclays, Deutsche Bank, and RBC to raise their year-end S&P 500 forecasts. However, significant concerns persist: the S&P 500's valuation is elevated at approximately 21 times forward earnings, comparable to early-year levels, and specific tariffs, such as the recent increase on steel and aluminum to 50%, pose tangible price risks. Marko Kolanovic, formerly of JPMorgan, has warned of a potential 5% to 10% stock market sell-off, citing trade tensions, signs of economic deceleration, and high valuations, while Giuseppe Sette of Reflexivity points to underappreciated recession and geopolitical risks, anticipating rangebound markets. Investor attention will also be on Apple's (AAPL) Worldwide Developers Conference for potential catalysts to rejuvenate iPhone sales after a period of stock underperformance, and the NFIB small business survey for insights into how tariffs are affecting smaller, more vulnerable enterprises.

Key Decisions for Investors

• Investors should closely monitor the forthcoming May CPI and PPI data for evidence of tariff-driven inflation, assessing its potential impact on consumer demand and Federal Reserve policy considerations.
• Given the S&P 500's valuation at approximately 21 times forward earnings and articulated concerns about a potential market correction, it is prudent to re-evaluate portfolio risk exposure, particularly to sectors sensitive to trade disputes and economic slowdowns.
• Key company-specific events to watch include Apple's WWDC for potential product cycle catalysts, especially as its stock has shown weakness, and the NFIB small business survey for indications of tariff impacts on a critical segment of the economy.
