The Daily Brief

Sterling closed yesterday's session just under $1.34, ending the day broadly flat against the dollar despite a sharp undershoot in UK inflation that materially altered the rate trajectory the market had been pricing. April CPI printed at 2.8% against expectations of 3.0%, the lowest reading since March 2025, with core inflation easing to 2.5% from 3.1% and services inflation dropping sharply to 3.2% from 4.5%. The downside surprise was driven by the Ofgem price cap reduction on 1 April and weaker recreation and travel pricing, both factors that bank research desks were quick to flag as temporary.

Markets responded by paring back BoE rate hike expectations, with pricing now consistent with two hikes by December rather than the more aggressive path baked in after the April MPC's 8-1 vote where one member already favoured a 25bp move. Pantheon Macroeconomics maintained its call for a July hike, forecasting inflation averaging 3.4% through the rest of 2026 and peaking near 3.7% in September and November under current energy-price assumptions. Lloyds Bank described the April moderation as "not a development to be dwelt upon", with both desks pointing to fuel inflation, which surged to a 2022 high last month, as the more durable signal.

The MPC's April Monetary Policy Report had already pencilled CPI in at 3.3% for Q3, with a 1.4 percentage point upward revision driven almost entirely by energy. Diesel pump prices have risen by more than petrol because of the elevated crack spread caused by the disruption to Middle Eastern refining capacity, a structural cost that is still feeding through to the headline rate. The undershoot does not change that story; it only changes the path.

What it does change is the relative narrative between sterling and its G10 peers. Against the dollar, GBP found support during the European session as global risk appetite improved, recovering to 1.34569 by late trade. Against the euro, sterling traded modestly firmer at 1.15681, with markets reading the inflation undershoot as marginally less hawkish for the BoE without removing the hike scenario entirely. The carry advantage that has supported the pound for much of 2026 has narrowed, but it has not closed.

For corporates with sterling receivables or payables in the second half, the practical question is whether the cooler inflation print marks a real turn or simply a base-effect pause. If Pantheon's profile proves correct and CPI tracks back toward 3.7% by the autumn, the BoE will be forced to revisit hike pricing and sterling's yield support returns. If the disinflationary pressure is more durable than the consensus reads it, the symmetry of the current cable range becomes asymmetric, with downside opening up. The case for layered cover in this environment is less about timing the next move and more about how wide the band of plausible outcomes has become.

The Dollar Index sits at 99.13 this morning, having retreated from Tuesday's six-week high of 99.40 as the Iran negotiation optimism that dominated yesterday's session continued to weigh on the safe-haven bid. The move reflects two crosscurrents the market is struggling to reconcile: a near-term reduction in geopolitical premium, and a confirmed hawkish tilt in the FOMC minutes released yesterday afternoon. The minutes from the April meeting showed that "many participants indicated that they would have preferred removing the language from the post-meeting statement that suggested an easing bias", and a majority noted that "some policy firming would likely become appropriate if inflation were to continue to run persistently above 2%".

This is the clearest official endorsement to date of the market repricing that has shifted Fed expectations from cuts to potential hikes over the second half of the year. The new Fed chair, Kevin Warsh, has been read by markets as more open to cuts than his predecessor, but the energy shock has left him with very little room to act on that disposition in the first half of his tenure. Several Fed officials are speaking through the week, and any divergence in tone from the minutes will move the front end of the curve sharply. Flash US PMI data and the latest housing prints are due in the next 48 hours and will frame the activity backdrop for the June FOMC. The dollar's softer tone this morning is not a directional signal; it is a positioning unwind after a tense few weeks, and a function of equity strength rather than rate repricing.

Yesterday's risk-on session was driven almost entirely by the suspension of planned strikes on Iran and Trump's comment that negotiations are in their "final stages". Three supertankers were observed via satellite passing through the Strait of Hormuz, the first material indication of resumed commercial traffic since March. The dollar's safe-haven flows reversed sharply, with the move amplified by short covering in EM currencies and a parallel rally in long-dated Treasuries.

For corporates with USD exposures, the implication is that the dollar's near-term direction is now being set by Tehran rather than by Washington. A constructive deal removes the safe-haven premium and exposes the dollar to the hawkish-Fed-meets-improving-risk narrative, which historically supports the currency but with much greater two-way volatility. A breakdown in talks restores the bid. Either outcome is binary, and option markets are pricing the asymmetry accordingly. The cost of optionality has risen meaningfully over the past fortnight, but it is still cheaper than being caught on the wrong side of the next headline.

The rand had its best session in several weeks yesterday, with USD/ZAR falling 1.38% to close at 16.4628, even as April CPI data released the same morning revealed the steepest monthly inflation print in over a decade. Headline CPI jumped to 4.0% from 3.1%, ahead of the 3.9% consensus and the highest reading since August 2024. The driver was almost entirely fuel: the petrol and diesel index rose 18.2% month-on-month, the largest single-month increase since the current CPI series began in 2008, with inland 93 octane petrol moving from R20.19 to R23.25 per litre and diesel from R21.28 to R28.80.

The rand strength is therefore not a vote of confidence in the domestic backdrop. It is the dollar leg moving lower in a global risk-on session, amplified by softer Brent and a renewed bid for EM carry. Core inflation also rose, to 3.6% from 3.2%, the highest reading since December 2024, suggesting that second-round effects are now visible beyond the direct energy pass-through. Services inflation lifted to 4.6% from 4.2%, the kind of broadening Governor Kganyago has explicitly said the SARB will respond to.

This sets up the 28 May MPC meeting as the most consequential SARB decision since the Middle East shock began. Forward-rate agreements briefly priced a small probability of a hike at the March meeting before the SARB held at 6.75%, and that pricing has now intensified materially. A 25bp hike would take prime to 11.50%, against a 3% target with a one-percentage-point tolerance band and current inflation already 100 basis points above target. The case for action is stronger than at any point since the new framework was adopted in November 2025; the case against is that the underlying disinflation trajectory is intact once fuel base effects roll off.

Analyst consensus is split. Some bank research desks are now openly arguing for a 25bp hike at next Wednesday's meeting, citing the credibility risk of holding through a print 100bp above target. Others maintain that the SARB will lean on its forecast that inflation reverts to 3% by late 2027 and treat the fuel shock as transitory, particularly if Brent's pullback proves durable. The QPM had previously implied a benchmark rate of 6.31% by end-2026; that projection now looks stale.

For corporates and treasurers with rand exposure, the rand's overnight strength masks an inflation problem that has not gone away. The 16.40s offer the most attractive USD/ZAR cover levels in over a month, and the cost of waiting until after the SARB decision is asymmetric: if the SARB hikes, the rand can extend gains and importers will face a less favourable entry point; if the SARB holds, the inflation backdrop becomes the dominant story and the rand gives back ground quickly. The local-currency yield pickup remains substantial, but the volatility around it has widened.

Brent settled at $105.02 overnight, having fallen 5.63% on the session, with WTI shedding 5.66% to $98.26. The trigger was Trump's comment to reporters that the US was in the "final stages" of negotiations with Iran, reinforced by satellite imagery showing three supertankers passing through the Strait of Hormuz for the first time since March. A deal would likely lift the naval blockades that have constrained Persian Gulf traffic, though physical recovery of flows is expected to take months rather than weeks; ADNOC's CEO has publicly cautioned that a full Middle Eastern oil-flow recovery is unlikely before late 2027.

The risk-on response was broad and clean. The S&P 500 closed at a record 7,432.97 (up 1.08%), the Nasdaq Composite gained 1.54% to 26,270.36, and the Dow added 1.31% to 50,009.35, breaking through the 50,000 level for the first time. Treasury yields softened across the curve as the inflation tail risk priced in over the past month receded. European equities had already closed before the US move, with the FTSE 100 finishing at 10,432.34 (up 0.99%), the DAX up 1.38%, and the CAC 40 up 1.70%.

The other major print of the session came after the bell. Nvidia reported Q1 fiscal 2027 revenue of $81.6 billion against a $79.1 billion consensus, with EPS of $1.87 against $1.77 expected, and guided Q2 to $91 billion. Data Center revenue grew 92% year on year as Blackwell 300 demand continued to outpace supply. The stock reaction in extended trading was muted, with the print broadly absorbed into already-elevated expectations. The wider read-across is that the AI capex cycle is still feeding directly into Nasdaq earnings power, which sustains the equity rally independent of macro developments.

The diplomatic optimism, the FOMC minutes, the UK and SA inflation prints, and the SARB meeting next Wednesday all converge into a single message for cross-asset positioning: the inflation impulse has not yet been definitively contained, and the market is pricing through it on the assumption that the Iran resolution will close the energy chapter quickly. That is a long position in diplomacy. For corporates and treasurers managing energy-exposed flows or commodity-sensitive receivables, the current levels in oil and the rand reflect an optimistic resolution that has not yet been signed. The asymmetry of the next move sits with the upside risk to volatility, not the downside.
