Constructive, but global diversification is essential.
MFS Week in Review
A review of the week's top global economic and capital markets news.
Tech wobbles, oil retreats
For the week ending 26 June 2026
As of midday Friday, global equities were lower for the week, with large-cap growth stocks lagging other asset classes. The yield on the U.S. 10-year Treasury note fell to 4.39% from 4.43% last Thursday. The price of a barrel of West Texas Intermediate crude oil (WTI) fell to US$69.50 from US$74.50 as Mideast supplies gradually started normalizing. Volatility, as measured by futures contracts on the Cboe Volatility Index (VIX), rose to 19.6 from 18.6 last week.
Macro news
White House gives Warsh room to maneuver
Central bankers past and present were in the spotlight this week as former Federal Reserve Chairman Alan Greenspan died at age 100. New Chairman Kevin Warsh overlapped briefly with Greenspan at the Fed when he was appointed as a governor by President George W. Bush. Last week in his first press conference as Fed chair, Warsh brought Greenspan’s inscrutable communications out of mothballs, dispensing with forward guidance — a tool Greenspan’s successors leaned on heavily — in a decision that may lead to increased bond market volatility.
The combination of falling oil prices and renewed Fed resolve to rein in inflation saw yields fall this week. It also seems to have bought Warsh a bit of leeway from the Trump administration, which has thus far been supportive of his actions. Treasury Secretary Scott Bessent said this week that he’s confident Warsh “will take the best path to satisfy both the inflation mandate and the growth mandate,” adding that President Trump retains complete confidence in the new chairman. Separately, the Wall Street Journal framed Warsh’s central dilemma around AI productivity thusly: if the payoff arrives soon, the Fed can sit still and let supply catch up with demand, as Greenspan did in the 1990s; if it is years away, however, current AI-fueled demand is already overheating the economy and waiting may prove costly.
Oil retreats to prewar levels as Hormuz reopens
WTI traded below US$70 late this week, and Brent slipped below US$75 to near pre-Iran-war levels, as traffic through the Strait of Hormuz continued to recover. Insurance rates have more than halved over the past week, with at least 172 ships transiting the strait since June 18, according to the Financial Times. Oman said it will keep the strait toll-free, while Iran is seeking fees for security and other services. However, the Wall Street Journal reported Thursday that U.S. officials believe Iran attacked a Singapore-flagged cargo vessel near Oman; no injuries were reported. Diplomatically, U.S. and Iranian negotiators reported progress in Switzerland toward a final agreement within 60 days. The U.S. Treasury authorized dollar-invoiced Iranian crude sales via sanctions waiver, and the U.S. and Qatar are working to give Iran access to about US$6 billion in frozen funds for humanitarian purchases. On Friday, the U.S. and Iran reportedly opened a communications line to coordinate on the Strait of Hormuz and avoid military escalation.
Tech wobbles as the AI valuation debate intensifies
South Korea’s KOSPI Index slid 10% on Tuesday, and the SOX semiconductor index dropped nearly 8% as tech shares came under pressure amid growing valuation concerns. The jitters eased somewhat after Micron Technologies reported blowout earnings and posted upbeat guidance after the close on Wednesday, though selling pressure returned early Friday. Investors are grappling with a familiar trio of concerns: higher interest rates, stretched valuations, and the risk that the billions being spent on AI infrastructure will outstrip eventual profits. Meanwhile, memory chip shortages are filtering into consumer goods pricing as illustrated by Apple raising prices 20% on a range of devices this week. This move sparked concern among investors that demand for devices will be undermined, sending shares of component makers lower late in the week.
U.S. growth revised higher, PCE in line
In May, core PCE rose 3.4% year over year and 0.3% month over month, both in line with forecasts, while personal income climbed a stronger-than-expected 0.7% and personal spending rose the same amount. The final reading of Q1 U.S. GDP was revised up from 1.6% to a 2.1% annualized pace. Durable goods orders fell 4.5% in May amid volatility in commercial aircraft orders, but April was revised higher to an 8.5% gain. Core capital goods orders rose a robust 1.6% in May, reversing April's 0.7% decline. U.S. new home sales unexpectedly fell 7.3% in May.
Inflation may soon peak as oil prices ease, but still-elevated core inflation suggests the Fed has more work to do to reach its target.
