UK GDP Preview: Pound Sterling’s Rate Support Faces a Test on 15 October
Britain’s August GDP figures could challenge aggressive Bank of England rate bets, Crédit Agricole warns, testing GBP Sterling’s recent appeal over the Euro.
Britain’s next growth figures will test whether the economic resilience supporting the Pound can survive more expensive borrowing and persistent energy pressures.
Crédit Agricole expects the August GDP release on Thursday 15 October to expose vulnerabilities that could make investors reconsider an aggressive outlook for Bank of England interest rates.
That would threaten one reason Pound Sterling (GBP) has held up against the Euro (EUR).
Pound to Dollar (GBP/USD): 1.324219 (+0.24%)
Euro to Dollar (EUR/USD): 1.118512 (+0.22%)
Describing the period since French bonds began selling off in late September, Crédit Agricole says: “A look at the FX market performance over that period would suggest that, next to the USD, the GBP has emerged as one of the best-performing G10 currencies vs the EUR.”
The official release is scheduled for 7am and will cover activity before the latest October turbulence in European bond markets.
In its recent preview, Crédit Agricole says: “Despite the recent EUR/GBP sell-off, we believe that there is a limit to the current appeal of the GBP over the EUR. For starters, we believe that incoming UK data like next week’s GDP data for August could highlight the fragility of the economy to tightening financial conditions and persistent stagflationary headwinds.”
The concern is that weak growth and elevated inflation could persist together, leaving less room for the Bank to raise rates without further restraining spending.
GBP to EUR Outlook: UK Growth has helped Pound Sterling compete with the Euro
The starting point is a stronger economy than many investors had anticipated.
The ONS initially estimated monthly growth of 0.4% in July, with services providing most of the increase.
Thursday’s publication will also incorporate wider historical revisions, so the new August number and any changes to the earlier growth path will need to be read together.
UBS’s latest assessment remains relatively constructive: “At the same time, UK economic data have generally remained resilient, reducing the likelihood of a significant deterioration in sterling, and we think the budget at the end of October is unlikely to shake markets meaningfully.”
That assessment gives the GDP release significance beyond a single month’s output.
Another resilient reading would preserve evidence that the UK can absorb tighter financial conditions, whereas a weaker report would challenge a support that UBS currently sees for the currency.
Crédit Agricole identifies both domestic and overseas reasons for the Pound’s relative strength: “The GBP’s appeal as a EUR safe haven proxy seems to rest on several traits: (1) the UK sovereign credit risk is significantly lower than that of France at the start of the French budget process and ahead of the Autumn statement due on 28 October; (2) the UK economy has surprised to the upside in recent months, and this has kept in place hawkish market BoE bets; while (3) the tightening of Eurozone financial conditions has forced European rate investors to pare back their ECB rate hike expectations, in a blow to the EUR rate appeal vs the GBP.”
A disappointing UK number would therefore weaken the growth argument for Sterling without necessarily removing investors’ concerns about France.
That distinction matters for GBP/EUR, where the relative attractions of the two economies can be more important than Britain’s performance in isolation.
Market pricing leaves room for disappointment
Crédit Agricole’s rates strategists see a gap between investors’ expectations and policymakers’ own guidance.
They write: “While market-implied BoE pricing already leans far more hawkish than the MPC members, the hawkish tilt in the communication combined with the smoothed inflation profile from energy price caps should sustain the bear flattening dynamics at least until the tightening cycle starts. Crucially, the rise in GBP rates, much like its EUR counterpart, has been driven predominantly by repriced policy rate expectations rather than by term premium expansion.”
In other words, much of the increase in borrowing costs reflects anticipated central-bank decisions, rather than an extra premium for lending to Britain over longer periods.
Evidence that activity is losing momentum could lead investors to trim those rate expectations and the yield advantage they offer Sterling.
That does not rule out an initial increase in November, the possibility examined in Exchange Rates UK’s coverage of MUFG’s Bank of England outlook.
It does make the scale of any subsequent tightening more open to challenge.
Crédit Agricole also expects policymakers to retain guidance tied to incoming data, rather than endorse the full tightening path priced by markets.
Its FX team concludes: “All this could in turn challenge the excessively hawkish market BoE rate outlook and erode the appeal of the GBP.”
When is the next UK GDP release?

Why does UK GDP matter for the Pound?
Growth evidence can change expectations for Bank of England rates and the returns investors expect from Sterling assets.
Does Crédit Agricole predict a specific August GDP number?
Its cited FX analysis warns about economic fragility without providing a numerical August GDP forecast.
