The Daily Brief

Sterling edged higher to $1.347 on Friday, capping its best week against the dollar since late February, as the ceasefire-driven decline in oil prices and hawkish Bank of England rhetoric combined to support the pound. That weekly gain of nearly 1.5% told the story of a currency caught between two powerful forces: cheaper energy lifting growth prospects and persistent inflation fears keeping rate-hike pricing firmly in place. The underpinning is fragile. Friday's US CPI report confirmed what the oil shock had already telegraphed: headline inflation surged to 3.3% in March, the highest since mid-2024, with energy costs up nearly 11% on the month.

The UK's own inflation picture is at least as uncomfortable: February CPI held at 3% before the full force of the energy shock, and March data, which will capture the bulk of the oil spike, is expected to push significantly higher. Manufacturers' input costs saw their sharpest monthly acceleration since 1992 in the March PMI, a leading indicator of the pass-through still to come. Markets are now pricing roughly a 67% chance of a Bank of England rate hike at the 30 April meeting, with at least one increase fully discounted by year-end and a meaningful probability of two. That is a dramatic inversion from pre-war expectations of two cuts this year.

Yet a growing divide is emerging within the MPC itself. Governor Bailey has cautioned that rate-hike expectations may be overstated, while Chief Economist Huw Pill has argued that the fog of uncertainty is no excuse for policy inaction. The tension between those views will shape the April decision and sterling's trajectory through the spring. The collapse of the Islamabad talks and the declared blockade of the Strait now threaten to unwind the energy relief that supported the pound last week.

Brent's overnight surge back above $100 puts immediate pressure on the UK's terms of trade, and gilt yields, which had retreated from their post-2008 highs, are likely to resume their climb as markets reprice the duration of the supply shock. Rabobank noted last week that three rate hikes appears excessive and that aggressive tightening would increase recession risks, a view that gains relevance as the conflict extends well beyond initial expectations. For businesses with sterling-denominated receivables or payables, the policy divergence between the BoE and the Fed is widening in a way that creates both opportunity and risk.

Sterling's relative strength against the dollar is underpinned by rate differentials, but the currency remains deeply vulnerable to any further deterioration in the energy outlook. With the April BoE meeting approaching and April CPI data arriving shortly after, the window for locking in current levels is narrowing as uncertainty compounds on both sides of the equation.

The Dollar Index is climbing back above 99 this morning, recovering from last week's decline after the collapse of the Islamabad peace talks forced markets to abandon the de-escalation thesis that had driven the greenback lower. Trump's announcement of a full naval blockade on Iranian ports, effective from 10 a.m. Eastern on Monday, has reignited safe-haven flows into the dollar, reinforcing its role as the market's preferred refuge in a crisis the United States itself initiated.

The structural logic is straightforward: the US is a net energy exporter, which insulates it from the worst of the supply shock, while every other major economy (Europe, Japan, the UK) absorbs higher input costs with far less fiscal headroom. Fed funds futures now imply roughly a 71% probability that the FOMC holds rates steady through December, up sharply from earlier in the week when ceasefire optimism had briefly revived talk of a cut. The March FOMC dot plot still shows one reduction this year, but seven of nineteen participants now see no cuts at all, and the longer-run neutral rate estimate has crept up to 3.125%. Markets are respecting the Fed's patience. For now.

Friday's CPI report crystallised the dilemma. Headline inflation surged to 3.3% year-on-year, driven by a 10.9% monthly spike in energy costs, the largest since the post-pandemic supply-chain dislocations of 2022. But core CPI came in slightly below expectations at 2.6%, and shelter costs continued their slow retreat, suggesting that underlying demand-driven inflation is not accelerating. Goldman Sachs observed that the Fed would likely look through the energy-driven noise so long as underlying conditions hold. That is the consensus view, but it is a consensus built on the assumption that the energy shock is temporary. The blockade announcement directly challenges that assumption.

The dollar's dual identity, simultaneously a safe haven and the currency of the belligerent power, creates a peculiar dynamic. It strengthens on risk-off flows even as the policies of its own government generate the risk. This has compressed volatility in the DXY into a relatively narrow range near 99 for most of April, but the blockade introduces a new escalatory dimension. Iran's Revolutionary Guard warned that military vessels approaching the Strait would be considered a ceasefire violation and dealt with decisively. The prospect of a naval confrontation in the world's most critical shipping lane is the kind of tail risk that could push the dollar significantly higher, or, if it triggers a broader loss of confidence in US policy, significantly lower.

For treasurers and FX desks managing dollar exposure, the asymmetry of the current setup is worth noting carefully. The dollar is well-supported at current levels by rate differentials, energy dynamics, and risk aversion. But the policy environment is generating volatility at a pace that renders static hedging strategies inadequate. Rolling short-dated options or layered forward structures may offer more flexibility than outright positions in an environment where the next headline from the Strait of Hormuz could move the DXY by a full point in either direction.

The rand had clawed back to around 16.40 against the dollar by Thursday's close, its strongest level in nearly a month, as the two-week ceasefire pulled oil prices lower and reignited demand for emerging-market carry trades. That rally, roughly 5% from the 17.23 high struck at the end of March, reflected the speed at which markets had priced in the de-escalation scenario. The collapse of the Islamabad talks and the declared Hormuz blockade now puts that entire move at risk.

South Africa's vulnerability is structural, not cyclical. As a net energy importer, every sustained dollar increase in the Brent price compresses the current account and feeds directly into the domestic inflation outlook. The SARB held the repo rate steady at 6.75% at its March meeting, citing deteriorating inflation risks from rising fuel prices and a weaker rand. The central bank's governor has been explicit that the conflict continues to reshape risk scenarios at each policy meeting. Forward-rate agreements are now pricing three potential rate hikes by early 2027, a wholesale reversal from the two cuts that had been expected before the war began.

There are domestic offsets worth noting. The S&P upgrade to BB in November 2025, the first in nearly two decades, continues to anchor longer-term sentiment. February inflation came in at precisely 3.0%, at the lower end of the target range, and the composite leading business cycle indicator rose 0.4% month-on-month in January, pointing to modest underlying growth momentum. Gold, which has recovered to around $4,780, provides a partial terms-of-trade hedge for South Africa's mining-heavy export profile. But these are structural supports, not short-term shields against a renewed oil shock.

The April fuel-price adjustment has already delivered a significant hit to consumers, prompting the government to cut the fuel levy at a cost of approximately R6 billion to the Treasury. Whether a similar intervention is feasible in May, when the full impact of the blockade will be felt at the pump, is an open question with fiscal implications. The SARB's next meeting in late May will have access to April CPI data and a clearer picture of whether the fuel shock is feeding through to broader inflation expectations or remaining contained as a supply-side disruption.

For businesses running rand-denominated cost bases or repatriating revenues into South Africa, the ceasefire-driven rally offered a more favourable entry point than anything seen in March. That window may now be closing. The rand's sensitivity to oil prices has become the single most reliable short-term driver of the pair, and with Brent surging back above $100 overnight, the path of least resistance for USD/ZAR points higher. Hedging programmes that capitalised on the sub-16.50 levels will look prescient if the conflict extends beyond the ceasefire expiry on 22 April.

Brent crude is surging again this morning, trading above $101 after jumping nearly 7% overnight as the market digests the twin shock of collapsed peace talks and a declared US naval blockade on Iranian ports. The move effectively reverses the relief rally that had pulled Brent from $119 in mid-March to below $96 last week, and it resets the macro calculus for every oil-importing economy on the planet. WTI crude is tracking above $104, with the Brent-WTI spread remaining elevated, a persistent feature of this crisis that reflects the disproportionate pressure on non-US supply chains.

The scale of the supply disruption remains extraordinary. The Strait of Hormuz has been effectively closed to most commercial traffic since late February, removing approximately 10 million barrels per day of oil production from the market. Saudi Arabia reported that attacks on its facilities have reduced production capacity by roughly 600,000 barrels per day and struck its East-West pipeline, a critical bypass route. The IEA's emergency release of 400 million barrels from strategic reserves has provided a temporary cushion, but the structural deficit persists. Back-month Brent futures (September at $84.64, October at $83.13) suggest the market expects some normalisation, but the forward curve still implies prices that would have been considered crisis-level just three months ago.

Equity markets are bracing for a difficult open. S&P 500 futures are down roughly 0.75 to 0.95% in early trading, while Nasdaq futures are off more than 1%. The S&P 500 closed Friday at 6,817, essentially flat on the day, as the CPI report's hot headline was offset by the tame core reading. But the blockade announcement changes the equation: it is no longer plausible to argue that the energy shock will be short-lived and mean-reverting. European futures are pointing lower, and Asian markets are likely to follow when they open. The VIX, which had settled to around 19, is poised to reprice as the weekend's developments are absorbed.

Gold is caught in the same crosscurrents that have defined its behaviour since the war began. It closed Friday near $4,780, heading for a third consecutive weekly gain, supported by a softer dollar and the prospect, now extinguished, of diplomatic progress. The declared blockade will test whether gold can reclaim its traditional safe-haven role or whether the higher-rate, stronger-dollar dynamic continues to exert gravitational pull. State Street's gold strategy desk maintains a base case of $4,750 to $5,500 by year-end but concedes that a prolonged conflict pushing Brent above $150 would weigh on gold through the Fed and dollar channel. China's continued physical buying has helped establish a floor around $4,000 to $4,100, but Western investors have been net sellers throughout the crisis.

The week ahead brings a dense calendar against an unstable backdrop. The US naval blockade takes effect Monday morning. The ceasefire formally expires on 22 April with no successor framework in place. Israel-Lebanon talks are scheduled in Washington on Tuesday, but Israel's intensifying operations in southern Lebanon complicate any prospect of a broader regional settlement. For markets, the overriding challenge is positioning around a conflict whose escalation ladder has no predictable endpoint. Rate expectations, energy pricing, and credit spreads are all moving in ways that reward flexibility and punish conviction, a reality that applies as much to corporate treasury operations as it does to institutional portfolios.
