Inflation Refuses to Cooperate

The April CPI report, released Tuesday, showed consumer prices rising 0.6% for the month and 3.8% year over year, the hottest annual reading since May 2023. Core CPI, excluding food and energy, climbed 0.4% for the month and 2.8% year over year, keeping inflation well above the Federal Reserve's 2% target.

Food prices increased 3.2% over the last year, with beef prices rising 14.8% year over year, driven largely by the energy shock rippling through the supply chain from the ongoing Iran conflict. Thursday brought another unwelcome data point: the Producer Price Index for final demand rose 1.4% in April, with goods prices up 2.0% for the month and the 12-month PPI rate for final demand rising 6.0%.

Newly confirmed Fed Chair Kevin Warsh, widely expected to favor rate cuts, now faces pressure from accelerating inflation including oil above $100 per barrel and shelter costs that doubled in April. As of Friday, the odds of a Fed rate hike at some point in 2026 climbed to 45% according to the CME FedWatch Tool, compared with just 1% a month ago. This repricing is what sent the 10-year Treasury yield to 4.59% by Friday's close, its highest level in a year. The Soil layer of any retirement plan, meaning the tax and rate-sensitivity architecture underneath the portfolio, deserves a close look in this environment. A 7% nominal return is not a 7% return if rising rates are quietly eroding bond values inside a taxable account. For more on how we think about this, see the Sporos Doctrine.

A Summit Without a Breakthrough

The Trump-Xi summit in Beijing produced no grand breakthroughs, delivering instead a broad stabilization of relations and a stated goal of preventing the superpower rivalry from spiraling further out of control. Trump signaled a potential Boeing aircraft order from China, describing it as "200 big ones," but investors were skeptical, and Boeing shares fell 4% on the news.

Trade envoys from both sides, led on the U.S. side by Treasury Secretary Scott Bessent, had reached what China described as "overall balanced and positive outcomes" at preparatory meetings in South Korea earlier in the week. But the absence of any concrete commitments on trade volumes, technology restrictions, or Iran-related cooperation left markets disappointed heading into Friday. The Strait of Hormuz situation remained the main pressure point: WTI crude futures rose above $103.50 per barrel on Friday and were on track for a weekly gain of roughly 10%, with tanker traffic through Hormuz still severely limited.

AI Euphoria Gets a Reality Check

The week opened with considerable optimism around artificial intelligence. Cerebras Systems (CBRS) surged 68% on its first day of trading Thursday, the biggest IPO of 2026 so far, as investors piled into the AI chip company. The enthusiasm faded quickly on Friday. Nvidia fell 4% on the day, dragging the broader tech sector lower, as rising bond yields made high-multiple growth stocks less attractive ahead of the company's earnings report next week.

Intel retreated more than 6%, while Advanced Micro Devices lost 5.7% and Micron Technology fell 6.6% as the Friday selloff concentrated in semiconductors. Still, the week's early gains were enough to leave the S&P 500 and Nasdaq each up roughly 0.3% for the five-day period. The week served as a reminder that sector-level volatility can obscure what is actually happening at the portfolio level. Investors sitting in an undifferentiated equity sleeve likely felt the whipsaw more than those with intentional position sizing across growth and income.

Looking Ahead

Nvidia reports first-quarter earnings on Wednesday, May 20, alongside Target, Lowe's, TJX, and Intuit. Home Depot reports Tuesday, and Walmart and Deere follow on Thursday. The consumer-facing results from Walmart and Home Depot will offer the first meaningful read on whether higher energy and grocery costs are pulling back discretionary spending. Wednesday also brings the release of the May FOMC minutes, which will be parsed for any signal about how the Committee is weighing the inflation resurgence against a still-resilient labor market.

Thursday's calendar includes Housing Starts, Initial Jobless Claims, the Philadelphia Fed Index, and preliminary S&P Global PMIs for both manufacturing and services. With the 10-year yield at its highest level in a year and rate-hike odds rising, any data that comes in hotter than expected could add further pressure to both bonds and the long end of the equity risk spectrum.
