Oil, gilts and a hot CPI print push yields to a 19-year high

UK 10-year gilt yields breached levels last seen before the financial crisis after oil prices jumped and inflation expectations rose. US and Indian equities fell too, though a Friday rebound softened the week's losses.

Yields are repricing a shock, not a new regime

The week's story is a chain, not a coincidence. Oil went up sharply after fresh US-Iran strikes in the Persian Gulf, gilt and Treasury yields went up in response, and equities fell in step until Friday, when oil eased and stocks recovered some of the ground. None of that requires a change of view about growth or inflation over the next few years. It requires only a view about what a supply shock to energy does to prices in the next few months, and markets have been quick to answer that question with certainty they do not really have.

The UK 10-year gilt closed the week at 5.19%, its highest level since before the financial crisis, and the move started before this week's oil spike, in the accumulation of worries about how much the government needs to borrow. That distinction matters. A yield rising because a country's fiscal position looks stretched is a different problem from a yield rising because oil jumped 7% in a fortnight. This week the two causes sat on top of each other, which is why the move looked so large, and why it is hard to say how much of it survives once the oil price stops moving.

What this changes for anyone holding a diversified portfolio is less than the week's headlines suggest. A bond portfolio built for a rising-rate world does not need rebuilding because yields rose further in a week that had an obvious, nameable cause. An equity portfolio that fell alongside oil's rise and recovered alongside its retreat is behaving exactly as one would expect given how much energy costs feed into corporate margins and consumer spending in the short run. The test of whether anything structural has changed is not this week's yield level. It is whether oil keeps rising once the immediate cause fades, and whether central banks treat that as a reason to tighten further or as a shock to be looked through. Neither the Bank of England nor the Federal Reserve has had the chance to answer that yet.

Equities

US · UK · India

The S&P 500 closed Friday at 7,656.981, up 0.86% on the day and enough to snap a four-session losing streak, though the index still fell 0.8% over the week as a whole.2
The rally coincided with oil and Treasury yields pausing their climb, after a week driven by strikes between the US and Iran in the Persian Gulf and an August CPI print that came in broadly in line, though core inflation rose slightly more than expected.3
The FTSE 100 closed the week at 10,650.44, down 1.67% over the five days, its steepest weekly fall since late July, after Associated British Foods fell more than 9% on demerger news and gilt yields weighed on sentiment through midweek.4
Friday's UK bounce came alongside a stronger-than-expected GDP reading and a 2% drop in oil prices on reports that Gulf and Iranian officials might discuss shipping arrangements in the Strait of Hormuz.5
India's Nifty 50 fell for a fifth consecutive week, closing at 23,398.10, down 2.09%, as rising oil prices revived concerns about inflation and growth and foreign investors continued to sell.6

Rates & Fixed Income

UK · US

The UK 10-year gilt yield rose to 5.19% this week, its highest level since before the financial crisis, driven by a mix of fiscal concern that predates this week and the fresh jump in oil prices.
A £5 billion auction of 2030 gilts still drew £16.2 billion in bids, suggesting the rise in yields is a repricing of risk rather than a shortage of buyers.7
The Bank of England did not meet this week; its next decision falls on 17 September, with markets largely expecting a hold even as some members voted for an immediate rise in July.8
US Treasury yields also rose sharply, with the 10-year and 2-year both up on the week, before easing slightly on Friday as oil and equities stabilised.3
The Federal Reserve likewise had no meeting this week; its decision on 15-16 September follows a hot producer price print and a core CPI reading that came in a touch above forecast.9

Commodities

Oil · Gas · Gold

Brent crude rose to $109.51 a barrel, up sharply on the week, after strikes between the US and Iran raised fears of disruption to shipping through the Persian Gulf.
WTI crude rose to $97.26 a barrel, up 4.9% on the week, tracking the same events.10
Both eased from their peaks by Friday as reports emerged of possible talks over shipping arrangements in the Strait of Hormuz.5
Henry Hub natural gas fell to $2.81 per million BTU, down 3.8% on the week, moving separately from the oil story.11
Gold slipped to $4,386.25 an ounce, down 0.7% on the week, a modest move against the scale of the moves elsewhere.12

Currencies

GBP

Sterling fell against the dollar this week, with GBP/USD ending at 1.3508, down 0.2%, as US yields rose alongside concern about UK borrowing costs.
Against the euro, sterling was little changed, with GBP/EUR at 1.1653, up 0.1%.

What I'm Watching

The week ahead

The Federal Reserve's decision on 15-16 September follows a week of hotter-than-expected producer and consumer price data, which narrows the room for anything other than a hold or a hike.9
The Bank of England meets on 17 September, a day after the August UK CPI print, in a week where several members have already signalled they see a case for raising rates.8
India's markets are closed on 14 September for a holiday, which will compress the week's trading into four sessions after a fifth straight weekly decline.13
Whether oil holds this week's gains or continues to retreat will do more to settle bond markets than anything a central bank says, since so much of the recent move in yields traces back to the same shock.
