The Daily Brief

Sterling closed Monday's session at $1.3508, clawing back a fraction of the ground lost during the previous week's sell-off, but the gain masked an intraday swing of more than a cent as markets first recoiled from the US blockade announcement and then rallied on hopes that the threat itself might force Iran back to the table. The pound remains roughly three cents below the one-month high of $1.348 reached last Tuesday during the ceasefire rally, and the pattern of sharp reversals shows how thoroughly geopolitics has displaced domestic fundamentals as the dominant driver.

The collapse of the Islamabad talks has further complicated the Bank of England's calculus. Rate expectations have whipsawed: markets entered 2026 pricing two cuts and are now positioned for at least one hike, with roughly 90% of economists surveyed expecting the BoE to hold at 3.75% on 30 April. JP Morgan sees a single hike in June as the most probable outcome, while the National Institute of Economic and Social Research warns that if energy costs persist at current levels for a year, the base rate could climb to 4.5%. Governor Bailey's signal that April is too soon for a majority to coalesce around a hike suggests the MPC is still trying to distinguish between a transitory energy shock and a durable shift in the inflation regime.

February's CPI reading of 3.0% now feels like a relic from a different era. March data, not yet published, will capture the first full month of the oil shock, and Bank staff had already projected inflation rising to 3.5% in the near term. The OECD's latest update underscores the UK's vulnerability: it now forecasts just 0.7% growth in 2026, the largest downgrade among G20 advanced economies, and expects headline inflation to reach 4%, the second highest in the G7. The combination of slowing activity and rising input costs, manufacturers' input costs saw their sharpest monthly acceleration since 1992 in the March PMI, puts the BoE in a classic stagflationary bind.

The gilt market remains fragile. Ten-year yields touched their highest level since 2008 on Monday morning before the late-session rally pulled them back 11 basis points. Two-year swap rates, from which mortgages are priced, have surged since the war began, and lenders have already begun repricing fixed-rate products higher. The government's fiscal room is thin: borrowing came in above forecast in February, and any material loosening to cushion households would risk reigniting the gilt volatility that scarred markets in 2022.

For clients with sterling-denominated exposures, the prevailing range of $1.33 to $1.35 represents a currency caught between competing forces: hawkish rate expectations providing a floor, and deteriorating growth prospects capping the upside. The ceasefire had briefly widened that range toward $1.35; the blockade has compressed it again. With the BoE meeting just over a fortnight away and oil prices once more dictating the narrative, volatility premiums are likely to remain elevated, making near-term rate locks more attractive than open positioning.

The Dollar Index sits at 98.79 this morning, recovering from Friday's dip below 99 after the blockade announcement restored safe-haven demand. The greenback had softened through last week as the ceasefire and diplomatic progress in Islamabad encouraged risk-on flows, but the collapse of negotiations, Vice President Vance departed without an agreement, citing Iran's refusal to commit on its nuclear programme, has snapped the dollar back into its conflict-era role as the market's preferred store of liquidity.

The March CPI report, released on Friday, delivered a mixed signal that the Fed is likely to find useful rather than alarming. Headline inflation surged 0.9% month-on-month, pushing the annual rate to 3.3% on the back of a 10.9% spike in energy costs. Core CPI, however, rose just 0.2%, bringing the annual core rate to 2.6%, both a tenth below consensus, with outright price declines in medical care, personal care, and used vehicles. The message: the oil shock is loud but, so far, narrow. Underlying inflation has not broken higher.

That distinction matters for the Fed's reaction function. At the March meeting, policymakers held rates at 3.50 to 3.75% and still signalled one cut this year, though the timing remains heavily data-dependent. The minutes, released last week, revealed concern that the conflict could generate persistent inflationary pressures, but also an acknowledgement that the shock may prove transitory if the strait reopens. Fed funds futures now price a roughly 71% probability of no change through December, with the small chance of a hike that briefly appeared after the BoE's hawkish tilt having been largely unwound.

The blockade introduces a new variable. US Energy Secretary Chris Wright acknowledged on Monday that prices are likely to rise further until meaningful tanker traffic resumes, but expressed confidence this would occur within weeks. Markets are less sanguine. Dated Brent, the physical spot benchmark, reached an all-time high above $144 last week, a $35 premium to futures that signals acute physical tightness. Even if the futures price stabilises around $100, the pass-through to US gasoline prices, now averaging $4.12 per gallon, up $1.20 since the war began, will keep headline inflation elevated through the second quarter.

The dollar's dual advantage, as both a safe haven and the currency of a net energy exporter, remains intact so long as the conflict persists. Institutional forecasts from the major desks still target DXY in the low-to-mid 90s by year-end on the assumption that the conflict resolves and the Fed resumes cutting, but the near-term trajectory is higher. For clients converting into or out of dollars, the current level near 99 sits in the upper half of the year's expected range, a consideration worth factoring into timing decisions on larger transfers.

The rand weakened to 16.56 against the dollar in Monday's session, retreating from one-month highs near 16.30 that the currency had touched just days earlier during the ceasefire rally. The reversal has been swift and familiar: a 2% gain on the ceasefire announcement on 8 April has been entirely unwound, and the rand is back to probing the weaker end of its post-war range. For a currency structurally exposed to both oil prices and global risk appetite, the blockade announcement delivered a double blow.

South Africa's inflation picture had briefly offered room for optimism. February CPI printed at precisely 3.0%, sitting at the lower end of the SARB's target range and reinforcing the credibility of the Bank's new 3% anchor. Before the war, markets had priced at least two rate cuts over the coming 18 months. That calculus has inverted entirely: at the peak of the oil shock in late March, traders were pricing four hikes. The ceasefire unwound some of that positioning, but the blockade has reignited expectations of higher-for-longer policy.

The SARB held the repo rate at 6.75% in March and is widely expected to hold again at its next meeting, with the Governor having flagged that risk scenarios would be revised upward to reflect persistent energy costs. The rand also faces a secondary headwind from diplomatic friction. Reports that Washington declined to accredit South Africa's delegation for the G20 finance meetings this week added a layer of political risk at a moment when risk sentiment was already deteriorating. South Africa's pivot toward the BRICS bloc and its complex relationship with both Beijing and Washington leave the currency exposed to shifts in geopolitical alignment that go beyond the oil price.

Structurally, South Africa's position as a net energy importer makes it one of the most directly affected emerging markets when oil prices spike. The April fuel price increase, driven by March's elevated crude levels, will feed directly into transport and food inflation, eroding consumer demand that was already fragile. On the brighter side, the S&P upgrade to BB in November 2025, the first in nearly two decades, and the government's progress on primary budget surpluses provide a floor that the rand did not have during previous oil shocks. Gold, trading above $4,700, also improves the terms of trade.

The consensus anchor for USD/ZAR remains around R17.00 for the full year, but the range around that anchor has widened materially. The currency touched R17.25 at the peak of the March sell-off and R16.30 during the ceasefire, a spread that reflects genuine uncertainty about how long the energy disruption persists. For clients with rand-denominated obligations or revenue streams, the current level near R16.56 sits in the more favourable half of that range, and the risk of a renewed move toward R17.00 or beyond is elevated if the blockade escalates further.

Brent crude is trading at $102.38 this morning, having surged 7% overnight after the US military confirmed its blockade of Iranian ports and coastal areas took effect at 14:00 GMT on Monday. The move marks a paradoxical escalation: Washington is now blockading the very waterway it had spent weeks trying to reopen. CENTCOM clarified that non-Iranian port traffic would not be impeded, but the practical effect is to layer a US naval operation on top of Iran's existing de facto closure, adding complexity without clarity. Only 31 vessels transited the strait in the past 24 hours, compared with roughly 130 daily before the war.

The physical oil market tells a more alarming story than the futures headlines suggest. Dated Brent, the spot benchmark for physical cargoes, hit an all-time high above $144 last week, a premium of more than $35 over futures. That gap, the widest in history, signals that actual barrels of oil are becoming acutely scarce even as the futures market prices in an eventual resolution. The global economy is running a daily shortfall of approximately 8 million barrels, and while Saudi Arabia has restored some pipeline capacity to the Red Sea, the infrastructure damage across the Gulf means supply normalisation will take months even in a best-case scenario.

Equities, paradoxically, rallied on Monday. The S&P 500 closed up more than 1%, erasing all of its losses since the war began on 28 February, buoyed by Trump's claim that Iran had called seeking to resume negotiations. The rally occurred even as oil prices surged, a sign that markets are pricing a near-term resolution with high confidence while simultaneously hedging against the opposite outcome in commodities. That disconnect is unlikely to persist. If the blockade holds without progress toward talks, equity markets will need to catch up to the reality that credit markets and bond yields have already been pricing.

Gold is trading near $4,760 per ounce, having recovered sharply from its March sell-off when investors liquidated positions to cover losses elsewhere. The metal is down roughly 14% from its all-time highs but remains well supported by the combination of inflation fears and central bank buying. Bond markets remain under pressure: 10-year US Treasury yields sit near 4.40%, and the global repricing of rate expectations continues. The ECB has opened the door to hikes if energy-driven inflation persists, the BoE is expected to tighten at least once, and the Bank of Japan has left the door ajar for April. Only the Fed is explicitly signalling patience, and even that patience has a shelf life if core inflation begins to move.

The broader risk is that what began as a supply shock is morphing into a demand shock. Shipping costs have blown out, fertiliser prices are surging, and jet fuel in Asia has climbed 175% this year. The OECD has downgraded growth forecasts across the G20, and private credit markets are showing signs of stress, with a further major asset manager capping fund withdrawals last week. For businesses navigating international payments, the operational message is straightforward: volatility is the base case, not the exception. Rate locks, forward contracts, and structured hedging are no longer precautionary. They are the cost of maintaining margin predictability in a market where a single headline can move currencies by a full percentage point before lunch.
