Memory chips cross $1 trillion as AI reshapes the semiconductor industry
On Tuesday and Wednesday, two of the world's largest memory chip manufacturers crossed the $1 trillion market capitalisation threshold within 24 hours of each other. Micron Technology surged 19 percent on Tuesday following a bullish analyst note from UBS, which tripled its price target citing long-term supply agreements at partially fixed pricing. SK Hynix climbed as much as 13 percent the following day in Seoul, becoming only the second South Korean company to reach the trillion-dollar mark, after Samsung Electronics had done so earlier in the month. For the first time in history, all three members of the global memory industry's "Big Three" were simultaneously valued above $1 trillion, representing a combined market capitalisation of roughly $4.1 trillion.
The engine behind these valuations is a single product category: high-bandwidth memory, or HBM. Unlike conventional DRAM chips, which store data for everyday computing tasks, HBM stacks memory dies vertically and connects them through thousands of microscopic channels, sitting directly beside an AI processor on a chip. This architecture delivers bandwidth measured in terabytes per second, making it the critical bottleneck in training and running large AI models. Both SK Hynix and Micron have sold out their entire 2026 HBM production capacity, meaning the constraint on the AI buildout is no longer processor supply or software but the availability of this specialised memory. The KOSPI, South Korea's main stock index, rose as much as 2.9 percent on Wednesday to a new all-time high, underscoring how much of the country's economic fortunes are now tied to the AI cycle.
The scale of the rerating is striking. A decade ago, memory chips were treated as a commodity business with thin margins and brutal cycles. Today, hyperscalers including Microsoft, Google and Amazon are signing multi-year supply contracts to secure access, providing revenue visibility that the industry rarely enjoyed before. The risk is equally clear: a business repriced entirely around AI infrastructure spending is exposed to any slowdown in that spending, and a supply glut could arrive quickly if all three manufacturers expand capacity simultaneously.
US households spend more and save less as energy costs squeeze budgets
The Federal Reserve's preferred measure of inflation, the Personal Consumption Expenditures price index, showed on Thursday that headline PCE rose 3.8 percent in April compared with a year earlier, with core PCE, which strips out food and energy, coming in at 3.3 percent, in line with expectations. Both readings remained well above the Fed's 2 percent target. More revealing than the inflation numbers themselves was the savings data buried in the same report: the personal saving rate fell to 2.6 percent in April, a historically low level and a sharp drop from the 4 to 5 percent range that prevailed through much of 2025.
The savings rate matters because it signals how much buffer households have to absorb further price increases. When energy costs rise sharply, as they have since the start of the year, households typically face a choice: cut back on other spending, or draw down savings. A saving rate of 2.6 percent suggests many American consumers are choosing the latter, continuing to spend on discretionary goods and services while leaving themselves with a thinner financial cushion. The concern for the Fed is that this pattern, if sustained, could delay the slowdown in demand that higher rates are designed to produce, making the job of bringing inflation back to target more difficult. At the same time, the containment of core inflation around 3.3 percent, while elevated, offers some reassurance that the energy shock has not yet spread broadly into the rest of the economy.
Canada's economy enters technical recession
Friday brought an unwelcome data point from across the border. Statistics Canada reported that real GDP contracted at an annualised rate of 0.1 percent in the first quarter of 2026, following a revised 1 percent contraction in the fourth quarter of 2025. Two consecutive quarters of negative growth on an annualised basis meets the standard definition of a technical recession, the first time Canada has recorded back-to-back contractions since the early months of the pandemic in 2020.
The result came as a significant surprise: the consensus among economists and the Bank of Canada had called for annualised growth of 1.5 percent. The primary drag was a sharp rise in imports, which subtracts from GDP calculations, driven in part by large purchases of gold products; business capital investment fell for a fifth consecutive quarter, pointing to persistent caution among firms. The nuance is that on a pure quarterly basis, growth was essentially flat rather than negative, suggesting the technical recession label may overstate the depth of the weakness. Statistics Canada's own early estimate for April pointed to a rebound of 0.4 percent, supported by the mining, oil and gas sector.
Canada occupies an unusual position in the current global environment. As a net energy exporter, the country stands to benefit from elevated oil prices stemming from the Iran conflict. But as an economy deeply integrated with the United States, it faces headwinds from an uncertain trade environment that have weighed on business investment for over a year. The Bank of Canada, which has held its policy rate at 2.25 percent through four consecutive meetings, faces a narrowing path: the GDP data effectively removed the prospect of a near-term rate increase, while underlying core inflation remains contained, leaving policymakers with limited urgency to act in either direction.
Oil retreats and equities rise on hopes of a Middle East deal
May ended with global equity markets at record highs, driven partly by momentum in AI-linked technology stocks and partly by growing expectations of a resolution to the Iran conflict. The S&P 500 posted a 5.3 percent total return in May, its second consecutive month of solid gains, bringing its quarter-to-date return to 16.3 percent. The Nasdaq Composite gained 8.4 percent in May and was up 25 percent quarter-to-date, powered by the same AI enthusiasm that drove the memory chip milestones earlier in the week.
Oil moved in the opposite direction, with Brent crude retreating toward $90 a barrel at one point as reports circulated of progress in negotiations between Washington and Tehran. The relationship between the two is direct: the Strait of Hormuz closure, which has been the dominant force pushing energy prices higher since late February, remains the central variable in global inflation expectations. A sustained fall in oil prices would relieve pressure on households and businesses across the advanced world, reduce the urgency of the rate decisions facing central banks from Frankfurt to Washington, and potentially allow economies like Canada to stabilise without a further tightening of financial conditions. The ceasefire discussions remained ongoing at week's end, and oil prices partially recovered, but the direction of travel was enough to lift market sentiment into the final days of the month.
