The Daily Brief

Sterling has spent the last month quietly repricing in the opposite direction to the one most forecasters expected in January. What was a market braced for further Bank of England cuts is now a market pricing the risk of hikes, after the energy shock pushed the inflation outlook up and forced the MPC to hold rather than ease. Sterling held near 1.34 through Wednesday's session and has softened only marginally in early Thursday dealing, a resilience that owes more to rate expectations than to any improvement in the UK's growth picture.

The domestic backdrop remains the same awkward split it has been all quarter. Underlying growth is subdued, the composite PMI has spent two months below the 50 line, and the labour market is cooling, yet services inflation near 3.7% is exactly the sticky component the Bank cannot look through. That combination is why the June decision came as a 7 to 2 hold, with two members already voting to lift Bank Rate to 4%, and why Governor Bailey framed the stance as tolerating temporarily above-target inflation only for as long as second-round effects stay contained.

The oil move tests precisely that condition. Higher crude feeds UK inflation directly through pump prices and indirectly through the energy content of everything else, and it lands just as the Ofgem cap and the autumn pay round come into view. A renewed energy spike narrows the Bank's room to tolerate, which is the mechanism markets are now leaning on as they price hikes rather than cuts into the sterling curve.

Sterling's relative firmness rests on that yield story. Bank Rate at 3.75% is the highest in the G7 after the Fed, gilts trade some 35 to 45 basis points above equivalent Treasuries, and that structural demand has let cable hold up better than the euro against the same hawkish dollar. The offsetting risk is domestic and political, with the Labour leadership transition still an unresolved premium on UK assets.

Against that, GBP/USD near 1.34 sits just below its 2026 average around 1.344 and well inside the year's 1.3165 to 1.382 range. The pivot is 1.35 on the upside and the June low near 1.3165 beneath, and the swing factor is external rather than domestic: if the projected Fed hike is removed as oil settles, the pair has room back toward 1.36 to 1.38, whereas a hike that actually lands pulls the relevant range down toward 1.28 to 1.30. The balance of risk is unusually two-sided, and it is the dollar leg, not the sterling leg, that will decide it.

The clearest read on the dollar this morning is a single repriced number: the implied probability of a September Fed hike has climbed to around 70%, up from 58% only a day earlier, as the oil surge reignited the inflation concern the Fed has been fighting for five years. The dollar index holds near 101, close to a one-week high, carried by a safe-haven bid and a rate-expectations shift moving in the same direction at once.

Yesterday's release of the June FOMC minutes confirmed a committee that is anything but settled. Under the new Warsh chair the Fed held at 3.5% to 3.75% and stripped its forward guidance back to the bone, but the dot plot already leaned toward a hike this year, with nine of eighteen participants pencilling in at least one and six seeing two. The minutes revealed the split beneath that median, some members judging policy already at or slightly below where it should end the year, others placing the appropriate rate clearly above the current range.

What has changed since that meeting is the energy picture the Fed explicitly flagged as the source of its inflation problem. May headline CPI at 4.2% was already uncomfortable, and a renewed oil spike threatens to keep the print elevated into the autumn, precisely the scenario that tilts a divided committee toward action. Money markets have responded by pulling hike expectations forward, with some houses now arguing for more than one move before year-end.

The dollar's strength therefore has two engines, a defensive haven bid and an offensive rate-differential bid, and both trace back to the same barrel of crude. That is also the vulnerability. The Dollar Index near 101 sits at the very top of its 52-week range of roughly 95.55 to 101.80, a level that already embeds a high probability of a September hike. If Hormuz de-escalates and oil retreats, the inflation premium and the hike it implies unwind together, and the dollar gives back the ground it has taken most quickly. The asymmetry from here runs against fresh dollar strength unless the energy shock persists.

The rand weakened past 16.40 to the dollar in Wednesday's trade, its softest level in nearly two weeks, caught in the same current pulling every high-beta currency lower. Two forces compounded: the safe-haven dollar bid drawing capital away from emerging markets, and a fourth straight session of softer precious metals, which matters more for South Africa than for most given gold and the platinum group's weight in the export basket.

Underneath the price action, the rand's policy backdrop is more supportive than the move suggests. The SARB broke a three-year pause to hike in May, a pre-emptive defence against the second-round effects of the oil shock, and Governor Kganyago has since noted that inflation expectations have drifted above the Bank's new 3% target. With the MPC due to meet again later this month, the domestic rate story leans hawkish, which under normal conditions would put a floor under the currency.

The problem is that South Africa's core vulnerability is precisely the one the market is now pricing. As a net energy importer, the rand is structurally exposed to exactly this kind of crude spike, which widens the import bill, feeds the fuel price, and pressures the current account at the same time the global risk mood turns against emerging markets. A hawkish central bank can lean against that, but it cannot offset a sustained terms-of-trade shock, and the July petrol relief that looked assured a month ago is now in question.

That leaves USD/ZAR near 16.40 in the more vulnerable half of its recent 16.19 to 16.44 range, and some way below the March extreme near 17.19 that the last full Hormuz closure produced. The reference point that matters is that earlier peak: it shows how far the rand can travel when the strait is genuinely disrupted rather than merely threatened. The balance of risk is skewed toward further weakness, back toward the high-16.00s and beyond, for as long as the escalation holds, with the SARB's hawkish stance the main counterweight rather than a cap.

Brent above $78 is the number driving every other market this morning. Crude has risen nearly 10% across two sessions, a roughly 5% jump on Wednesday alone, after a second US strike on Iran and Tehran's warning that it could close the Strait of Hormuz reversed the calm that the June ceasefire had restored. This is a sharp reversal of the supply-glut thesis that took hold only weeks ago, when OPEC+ was lifting quotas and prices had drifted back to pre-war levels near $74.

The cross-asset reaction has been textbook risk-off with an inflationary twist. Wall Street slipped on Wednesday, the FTSE and continental indices fell harder, and volatility gauges jumped, yet bond yields rose rather than fell, with the US 10-year back near 4.58% and gilt yields up sharply, because the shock is read as inflationary rather than deflationary. That is the signature of an energy-supply scare rather than a demand scare, and it is why safe-haven flows went into the dollar rather than into Treasuries or gold.

The policy thread ties the day together. The same barrel that is lifting Brent is behind the Fed's revived hike pricing, the BoE's two dissenters, the SARB's May move, and today's ECB minutes, which the market will read for how much conviction the euro area's doves still hold now that energy is climbing again. When four central banks are all responding to one commodity, currency volatility widens and the correlations that hedging programmes rely on start to shift.

The counterweight is verbal. The US administration has signalled it expects prices to fall as tankers continue to clear the strait, and it has played down the odds of a return to full-scale war, which is the cap keeping Brent below the triple digits it reached in March. Against that, Iran's threat to close Hormuz is the tail that took Dubai crude above $160 at the peak of the earlier crisis.

That leaves Brent near $78 caught between a $74 pre-escalation floor and a $100-plus tail that only a genuine strait disruption would open. The asymmetry is clearly to the upside while the waterway is contested, and it is that skew, not the spot level itself, that is repricing rates and currencies across every market in this brief.
