Coming into 2026, the Fed, the ECB, and the RBI were all leaning the same direction: rates coming down. A recurring oil shock out of the Strait of Hormuz has since pushed one of them into its first hike in three years, pushed another to price real hike odds for the first time this cycle, and forced the third to raise its inflation forecast while cutting its growth one. This letter is about what changes when the thing driving three separate central banks is the same barrel of oil.
Coming into 2026, the consensus was simple: rates were heading down. The Fed had cut through 2025. The RBI had cut 100 basis points into last September. The story for this year was supposed to be the last mile of disinflation, not a fresh round of tightening. Then, on February 28, US and Israeli strikes on Iran shut the Strait of Hormuz to a fraction of its normal traffic — a corridor carrying roughly a fifth of the world's oil and LNG — and the rate-cutting story broke. What's happened since isn't one oil spike that fades. It's a shock that keeps recurring, and three of the world's most-watched central banks are now responding to it in three different ways, on three different clocks.
The European Central Bank raised its three key rates by 25 basis points on June 11 — its first hike in three years, breaking an easing cycle that had defined its policy through most of 2025. The decision was described as robust across a range of scenarios for how the shock could evolve, with eurozone headline inflation revised up to an average of 3.0% for 2026 and growth revised down to 0.8%. May's actual inflation print came in at 3.2%, the highest since 2023, and — the detail that matters most — core inflation excluding food and energy also climbed, from 2.2% in April to 2.5% in May. That is the sign a central bank watches for most closely: a shock that starts in energy prices spreading into the rest of the economy rather than staying contained.
By July 1, at the ECB's own Sintra symposium, that unity had already cracked. Policymakers were reported as divided on whether borrowing costs need to rise again, with real doubt inside the institution about whether a second hike arrives at all this year. Then, on July 15, fresh US strikes on Iran and a reinstated naval blockade near Hormuz put oil back at the top of the ECB's worry list just a week before its July 23 meeting — most economists still expect a hold, but a September hike is now the more-likely-than-not base case if oil stays elevated.
The Federal Reserve's own June Summary of Economic Projections told the same story from the American side: officials raised their median inflation projection for the year while lowering growth, and market pricing for 2026 rate cuts collapsed from two cuts priced in January to effectively zero by mid-year. Fed Chair Kevin Warsh's message has shifted with the data — hawkish on inflation risk at the June Sintra forum, then somewhat more reassured on July 8, noting that inflation risk had eased over the prior few weeks. That reassurance predates the July 15 escalation. As of this week, CME's own FedWatch pricing shows a 63% probability the Fed holds at its July 29 meeting against a 37% probability of an actual 25 basis point hike — and September hike odds are running hotter than July's, despite a recent, sharp month-over-month drop in headline CPI that several traders are already calling a possible head-fake, since it doesn't yet reflect the renewed oil move.
Markets are trying to hold two facts at once: a single month's inflation print just fell by the most in years, and traders are simultaneously pricing real odds of a hike at the next meeting. Both can't be the settled truth. One of them is about to be wrong.
The Reserve Bank of India's June 3–5 policy meeting held its repo rate at 5.25% for a second straight review — but the more informative move was in the forecasts underneath that hold. The RBI cut its FY27 GDP growth forecast to 6.6% from 6.9%, and raised its FY27 CPI forecast to 5.1% from 4.6%, citing West Asia tensions, elevated crude, rupee depreciation from foreign fund outflows, and monsoon risk together in the same breath. The RBI's own May survey found household inflation expectations had risen to 7.8% from 7.2% — the specific number a central bank watches to judge whether a shock is staying temporary or starting to embed itself in how people actually plan around prices. Most analysts still don't expect an RBI hike this calendar year, with any move more likely pushed into early 2027 — India remains the one major economy in this letter still officially leaning toward eventual cuts, just later and more cautiously than anyone assumed in January.
For the rupee and for any business pricing in dollars, the transmission is direct and familiar by now: elevated Brent (currently near $85, having spiked well above $100 twice already this year) widens India's import bill, pressures the currency, and shows up in the RBI's own inflation forecast before it shows up anywhere else. The Indian crude basket easing toward $86 in recent weeks bought some room — the renewed Hormuz escalation is the reason that room may not last.
Three central banks, three different responses, one shared cause. The ECB has already hiked once and is genuinely split on a second. The Fed is pricing real hike odds for the first time this cycle, having started the year expected to keep cutting. The RBI has held rates but is doing the quiet version of the same thing — marking up its inflation forecast and marking down its growth forecast in the same release. None of this is really about monetary policy diverging. It's about the same barrel of oil moving through three different economies at three different speeds. The risk to this thesis, stated plainly: if the current Hormuz blockade resolves quickly and Brent genuinely settles back toward the low $80s or below, all three of these hawkish pivots could reverse just as fast as they arrived — a majority of economists surveyed still don't expect the Fed or ECB to actually deliver a second move this year, and a quick de-escalation is the specific scenario in which they'd be right.
