Charts of the Week: Calmer Waters, New Currents

Equity Momentum and Global Surprises — Still Moving Together One of the more telling features of global equity markets in 2026 has been the persistence of the correlation between non-US equity momentum and global growth and inflation surprise indices. Equity markets outside the United States have generally prospered when economic data have beaten consensus expectations and when inflation surprises have been negative — a combination that has historically been associated with stronger corporate earnings and a more benign policy backdrop in economies other than the US. That correlation has held reasonably well through the turbulence of the past few months, even as the Middle East conflict introduced significant noise into both the economic data and the financial market signal. What the chart reveals this week is a picture of moderate but not alarming deterioration: global growth surprises have softened at the margin, consistent with the energy cost headwinds that have weighed on European and Asian activity, but the relationship between equity momentum and the broader data pulse remains intact. It is a signal that market participants continue to track economic fundamentals rather than purely geopolitical newsflow — a modestly reassuring sign that the underlying framework for assessing the global cycle has not broken down.

The Fed Decouples: Why Oil and US Two-Year Yields Have Parted Ways For much of 2026, oil prices and US two-year Treasury yields moved in close alignment. The logic was straightforward: higher oil prices raised inflation expectations, which in turn pushed market participants to anticipate a more hawkish Federal Reserve, lifting short-dated yields in the process. That relationship held with notable consistency through the March escalation and the months that followed, as energy market shocks and monetary policy expectations fed off each other. What this week’s chart captures is a striking breakdown in that correlation. As oil prices have fallen on the back of the US-Iran memorandum of understanding and the associated unwinding of the geopolitical risk premium, US two-year yields have not followed them lower. The reason is last week’s Federal Reserve meeting. Under new chair Kevin Warsh, the Fed delivered a hawkish dot plot that shifted the median year-end projection to a hike, making clear that the easing cycle previously priced by some market participants is no longer the central scenario. The message is important: the deflationary impulse from lower oil prices is being offset — at least in the Fed’s framing — by persistent underlying inflation pressures and a commitment to keeping policy tight.

Flash PMIs Signal Easing Supply Chain Stress and Softer Price Pressures June’s flash PMI surveys, released this week across the major advanced economies, provide a timely read on how the global manufacturing and services sectors are absorbing the shifting macro backdrop. Two findings stand out. First, supplier delivery times have improved (or not lengthened as much as they had in the prior two months). This finding coheres naturally with the broader narrative: lower oil prices reduce transport and energy input costs, while the resumption of Strait of Hormuz shipping flows — examined in more detail in chart 4 — is beginning to reduce the freight disruption and re-routing costs that had been building since the conflict escalated. Second, output price inflation in manufacturing has softened, suggesting that some of the pipeline pressure from earlier energy cost spikes is beginning to fade.

Hormuz Traffic and Oil: A Coherent Story of Tentative Normalisation The recent US-Iran memorandum of understanding to work towards a final deal, though not without subsequent flare-ups, has already brought relief to markets, most visibly in crude oil prices. This should go a long way towards unwinding the inflation-related concerns that previously elevated oil prices had stoked. While the pullback has owed much to anticipation of the glut of pent-up supply expected to follow, certain trackers of shipping volume through the Strait of Hormuz, such as the IMF’s, already point to a marked pickup in traffic, even if it remains well below pre-conflict levels. Should this normalisation of shipping flows persist, it would lend continued justification to a corresponding easing in oil prices, energy-related inflation and, by extension, headline inflation — a welcome development for central banks grappling with the delicate balancing act of reining in price pressures without dampening growth too sharply.

South Korea’s Trade Data Flag a Modest Softening in Global Demand South Korea’s trade data serve as one of the global economy’s most useful early warning systems. As one of the world’s most open economies, with exports spanning semiconductors, petrochemicals, steel, automobiles and consumer electronics, South Korea’s monthly trade figures provide a timely and broad-based read on the state of global demand. This week’s data show a slightly softer picture than the strong prints that characterised much of the first quarter. Headline export growth has moderated at the margin, and crucially, semiconductor exports — which had been the most dynamic component of the trade data, propelled by AI-related chip demand — have also come in a touch below the exceptional run rates seen earlier in the year. This is not, in itself, alarming: some moderation from peak rates was always to be expected, and the semiconductor cycle remains structurally supported by the scale of AI infrastructure investment globally.

A Super El Niño on the Horizon — The Next Inflation Risk With that said, while one driver of price pressures seems to be ebbing for now — albeit not without the risk of future flare-ups — another potential inflationary risk looms on the horizon. The chart illustrates the transmission mechanism. It plots Thailand’s milled rice production (left axis) against Australia’s Southern Oscillation Index (right axis), a well-established barometer of El Niño and La Niña conditions. The convention is straightforward: SOI readings persistently above +8 indicate La Niña, associated with above-average rainfall across Southeast Asia and broadly supportive crop conditions; readings persistently below -8 signal El Niño, which brings drought stress and reduced water availability across the region. The historical relationship is striking. The sharp negative SOI troughs around 2002–03, 2009–10 and most dramatically around 2015 all coincide with visible falls in Thai milled rice output. The severe El Niño of 2014–16 produced both the deepest SOI trough in the series and the sharpest single drop in rice production, to below 24,000 thousand tonnes. As meteorological authorities have been warning for some time, the world appears to be facing an imminent Super El Niño event, with the SOI already drifting back towards negative territory in recent months. Were a significant El Niño to materialise in the second half of this year, the implications for Thai rice output — and by extension for Asian food price inflation — could be substantial. Central bankers, in other words, may find themselves having to wrestle with a new inflationary impulse just as they had begun to hope the worst was behind them.
