The Daily Brief

Dave Ramsden added his name to the Bank of England's growing hawkish chorus in yesterday's session, saying he would back higher rates if upside inflation pressures persist. That puts him alongside Bailey, Breeden and Lombardelli, and it lifted the market's November hike probability to roughly 85%. Sterling's response was telling: a brief lift to 1.326 that faded into the close. When the most senior voices on the committee are all leaning the same way and the currency barely moves, the hawkishness is already in the price, and the market is looking for something else to trade.

It found it a few hours later in Chancellor Healey's conference speech, which leaned hard on fiscal discipline and the rising cost of servicing the national debt. The gilt market heard a warning rather than a reassurance. Two-year yields rose around six basis points to 4.75% and the 10-year closed at 5.43%, a level not seen in nearly two decades. That combination matters: a front end pushed up by rate expectations and a long end pushed up by fiscal anxiety is the signature of yields rising for the wrong reasons, and it is why a steeper gilt curve is weighing on sterling rather than supporting it.

The clearest measure of that is the gap with the United States. UK 10-year yields now sit around 15 basis points above Treasuries, a premium that in a calmer regime would pull capital towards the pound. Instead, investors are treating it as compensation for holding UK duration into the 28 October Budget, with the Fed having already tightened and the BoE still at the talking stage. Until the Budget arithmetic is visible, the rate differential flatters sterling on paper without translating into demand.

Sterling opens this morning near 1.324, only 0.3% above September's low of 1.3203 and effectively on top of the 1.325 quarter-end model estimate, with June's 1.3142 the next meaningful reference below. The balance of risk leans towards a test of 1.32 before any return to 1.33: a hawkish BoE is fully priced, while the fiscal premium is still building. The gauge worth watching is the gilt-Treasury spread. If it keeps widening while sterling slips, the market is charging for Budget risk rather than rewarding the BoE, and only a credible fiscal plan or a clear softening in US data is likely to change that.

The market has moved further towards an October Fed hike overnight, with probability now around 70%, up from roughly 65% at the start of the week, and a December follow-up priced at just over even odds. The repricing is visible across the curve: the 10-year Treasury yield has pushed to 5.26%, its highest since 2007, the two-year sits at 4.96%, and the Dollar Index holds near a two-month high at 101.29 this morning. What has changed is not the data but the oil price, and with it the market's confidence that energy-driven inflation will fade on its own.

The mechanism is twofold. Tehran's reported pessimism about reaching a Hormuz deal before the November midterms extends the period in which energy prices feed through to US inflation, which hardens the Fed's reaction function. At the same time, strong activity data and a deteriorating fiscal outlook are adding term premium at the long end. The dollar is collecting support from both channels at once: higher expected policy rates on one side, and a haven bid on the other whenever oil spikes. That is an unusually durable combination, and it explains why the index has held its gains even on days when risk sentiment has been merely soft rather than fearful.

Today's JOLTS openings, expected at 7.24 million, and September consumer confidence, seen near 90, are the first test of how much of that pricing the economy can justify. The heavier lifting comes tomorrow with August PCE, where core is expected at 0.3% month on month and 3.4% year on year, and on Friday with payrolls, where consensus looks for just 84,000 jobs after 162,000. The striking feature is that the market is pricing a 70% hike chance while expecting job growth to roughly halve. The Fed is being priced on inflation, not employment, which means a soft labour print may do less to weaken the dollar than it normally would.

With the index at 101.29, about 2.6% above its four-month low near 98.7, the asymmetry sits in the rates market rather than the chart. At 70%, roughly a third of an October hike is still left to price, and a core PCE print at or above 0.3% would push that towards certainty and carry the dollar with it. The route lower is narrower: it likely needs payrolls well below the 84,000 consensus and a PCE miss together, because either alone is unlikely to outweigh the oil-driven inflation story that now anchors the Fed debate.

South Africa's October fuel price adjustment is due within days, and on current data it will be severe: petrol is tracking an increase of close to R3 a litre, and wholesale diesel is heading for around R33 inland, above May's record. That is the backdrop against which the rand traded in yesterday's session, and it explains why the currency's weakness now carries a cost that extends well beyond the exchange rate itself. The rand slid to around 16.41 by the close, its weakest level since early August, as stalled US-Iran talks pushed oil higher, the dollar drew haven demand and softer precious metals removed a familiar cushion. The timing is the problem.

The fuel formula captures both the dollar oil price and the exchange rate, so every cent the rand loses in the final days of the review window adds directly to the under-recovery. The currency and the commodity are not offsetting each other this month; they are compounding. The bond market is reflecting that squeeze. The 10-year yield has climbed to 9.05%, near a six-month high, and the spread over Treasuries has widened back to roughly 379 basis points after narrowing late last week. Today's auctions of the 2038, 2039 and 2042 bonds will show whether foreign demand for South African duration is holding up at these levels.

Last week's rate increase anchors the front end, but with headline inflation at 4.4% and fuel set to push it higher in September and October, the long end is being asked to absorb inflation risk that monetary policy has not yet caught up with. Tomorrow's August trade data adds a further test, with consensus expecting the surplus to narrow from R20.1bn to around R3.5bn as the oil import bill swells. A shrinking surplus erodes one of the rand's structural supports at precisely the moment its cyclical supports, gold and risk appetite, are also fading.

At 16.44 this morning, the rand sits at the very top of its 16.05 to 16.44 September range and a short step from last week's high near 16.50, with the 16.98 peak from early August marking the upper edge of the band it has held since. The quarter-end model estimate near 16.29 now looks optimistic. While Brent holds above $105, a move through 16.50 looks more likely than a return to 16.29, and a genuine reopening of Hormuz remains the one catalyst capable of reversing that balance quickly.

Five. The Reserve Bank of Australia raised its cash rate by 25 basis points to 4.60% this morning, a unanimous decision that takes Australian rates to their highest since 2011 and marks the bank's fourth hike this year. It is also the fifth major central bank to tighten in September, after the Fed, the ECB, the Bank of Japan and the SARB. The Bank of England is now the only one of the large central banks relevant to Mercury's corridors that has not moved, and the global tightening wave is shaping how every other rate market is priced.

The driver behind all five is the same, and it strengthened overnight. Brent is trading at $107.14, up 1.8%, after Iranian officials reportedly signalled little prospect of an agreement to reopen the Strait of Hormuz before the US midterm elections in November. The resumption of flows through a key Saudi pipeline, which might otherwise have eased the supply picture, has been overwhelmed by that shift in timeline. For markets, the difference between a deal in weeks and a deal after November is the difference between a temporary energy shock and a quarter's worth of pass-through into inflation data.

That repricing is visible in bond markets around the world. US 10-year yields are at 5.26%, UK gilts above 5.4%, Japan's 10-year near a 30-year high around 3.1%, and South Africa's above 9%. Equities are absorbing the pressure less comfortably: US futures are down around 0.25% after a weak session that saw sharp falls in several mega-cap technology names, while the Nikkei has lost around 1.4%. Gold has recovered a little ground to around $4,128 after Monday's 2% drop, but it is no longer providing the reliable offset to oil that commodity-linked currencies have leaned on.

Tomorrow's quarter-end adds a layer of noise, with rebalancing flows likely to be heavier than usual after a quarter in which bonds have sold off hard and energy has outperformed. That can exaggerate moves in either direction over the next 36 hours, and it is worth treating any sharp swing into Wednesday's close with some caution before reading it as a new trend. Brent at $107 sits about 2.5% above its $104.5 quarter-end model estimate and less than 1% below last week's intraday high near $108.2, having traded below $100 only a week ago.

With Tehran now pointing beyond the midterms, the route back to $100 through diplomacy is narrowing, and a retest of the $108 to $109 area looks more likely than a return to the quarter-end estimate. A surprise breakthrough in talks remains the principal risk to that view, and it would reverse the move quickly.
