GBP/USD + GBP/EUR Market Update

Post-Central-Bank Hangover: GBP/USD Slips to Near-July Lows as Hawkish Fed Dot Plot and Dovish BoE Hold Weigh, Friday, 18 September 2026

GBP/USD: 1.3368 | GBP/EUR: 1.1638 | EUR/USD: 1.1487

A week that delivered three central bank decisions in five days closes with the dollar firmly in the driving seat. The Fed raised its policy rate by 25 basis points to 3.75%-4.00% in a unanimous 12-0 vote, and the September dot plot lifted the median 2026 rate projection to 4.1%, up from 3.8% in June, signalling at least one further hike before year-end. The BoE voted 6-3 to hold Bank Rate at 3.75%, with three members preferring an immediate rise to 4.00%, leaving sterling without a fresh hawkish catalyst to offset the dollar's momentum. Today's London session is data-light, so position-squaring and end-of-week flows will dominate.

Overnight & Market Tone:

GBP/USD fell to 1.3351 on 17 September, down 0.22% on the session, and our database shows a modest recovery to 1.3368 in early London trade, though the pair remains near its weakest level since late July. Governor Bailey, in prepared remarks, acknowledged the global energy shock has so far had a limited impact on UK prices and wages, but warned that prolonged volatility could put greater pressure on inflation and increase the need for a rate hike, language that offered little comfort to sterling bulls. Forex.com noted that the USD traded at a seven-week high after the FOMC decision, and that broad dollar strength is capping recovery attempts across G10. GBP/EUR has eased to 1.1638 from Thursday's 1.1669, consistent with a modest unwind of the sterling-positive MPC positioning that had built ahead of the decision. Risk sentiment is cautious: US stocks slipped after the Fed hiked and hinted more increases may be on the way, and European equity futures are pointing to a softer open for the FTSE 100. Brent crude remains elevated, with the front-month contract opening near $105.57/barrel, keeping energy-driven inflation fears alive across all three currency pairs.

UK Data & Bank of England:

The week's defining domestic event is now behind us. The MPC minutes noted that protracted Middle East conflict has contributed to further increases in crude and refined energy prices since the previous meeting, and that UK CPI inflation rose to 3.1% in August, with the committee warning it is likely to rise further over coming quarters. In his post-decision video statement, Governor Bailey confirmed the hold at 3.75%, noting that higher global energy costs have so far had a limited effect on price and wage-setting in the UK, but cautioning that the longer this volatility persists, the more likely it is that Bank Rate will need to rise. The 6-3 vote split is unchanged from July, meaning the hawkish minority (Greene, Mann and Pill) has not grown, which markets read as a mild disappointment for sterling. Market participants are currently pricing in at least one 25bp BoE hike in 2026 amid inflation risks from higher energy prices, with the next opportunity at the 5 November meeting, which also carries a full Monetary Policy Report. The MPC also set out a multi-year path to reduce the stock of UK government bond purchases to zero, through annual sales of £20 billion alongside maturing gilts, a QT commitment that adds modest upward pressure to gilt yields at the long end. The 10-year gilt yield has been elevated in recent weeks, consistent with the broader global bond sell-off driven by energy-inflation repricing; the 14 September reading cited by Pound Sterling Live placed it at 5.439%, the highest since 2007, though some modest relief has been seen since.

European Backdrop & EUR/USD:

The ECB raised all three key rates by 25 basis points on 10 September, taking the deposit rate to 2.50% from 16 September, its second hike of 2026. Lagarde cited upside risks from gas prices, potential supply disruptions and trade tensions, while noting that wages have not yet responded to the energy shock, suggesting the episode is primarily supply-driven rather than a wage-price spiral; no pre-commitment was made on future moves. For the next ECB meeting on 29 October 2026, market pricing implies a 53% probability of a further hike to 2.75%, leaving the outcome finely balanced. Eurozone inflation accelerated to 3.3% in August, its highest level in three years and well above the ECB's 2% target, providing the fundamental justification for continued tightening, though there have been few signs of the second-round inflation effects policymakers typically fear when energy prices surge. On EUR/USD specifically, the pair has slid from above 1.1600 at the time of the ECB decision to 1.1487 this morning, a move almost entirely attributable to the Fed's hawkish pivot rather than any deterioration in the euro's own fundamentals. EUR/USD dipped below 1.1600 on the ECB news and steadied near 1.1610, with the hike already fully priced; markets now price more tightening than the ECB's own baseline requires, leaving the euro's rate support exposed. The Fed-ECB deposit rate differential now stands at approximately 137-150 basis points in the dollar's favour (Fed target midpoint 3.875% versus ECB deposit rate 2.50%), and the dot plot implies that gap could widen further if the Fed delivers another 25bp move before year-end. EUR/USD is forecast to trade between 1.13 and 1.19 over the next three months, with a base case of 1.15 to 1.18; this is the pair where the two policy stories are closest together, and therefore the one with the least directional conviction. For treasurers with direct EUR/USD exposures, the near-term risk is asymmetric to the downside: any further hawkish Fed communication or escalation in Middle East energy disruption could push the pair towards the 1.14 area, while a meaningful EUR/USD recovery requires either a Fed pause signal or a clear ECB commitment to further hikes at October's meeting.

US Backdrop:

The Fed raised its policy rate to 3.75%-4.00% in a unanimous 12-0 decision, and the typical FOMC participant now expects at least one more quarter-point hike before the year closes out. US retail sales for August jumped 6.0% year-on-year, well above the 4.7% forecast, and import prices ran hot at 7.0% year-on-year against a 6.4% forecast, pointing to consumer demand and imported cost pressure that have not cooled the way the Fed would like. Fed Chair Kevin Warsh has not submitted an interest rate projection for the dot plot, consistent with his long-standing criticism of forward guidance; his absence from the dots may point to a broader shift in how the Fed communicates its policy outlook. Today's US calendar is light, with no tier-one releases scheduled, so the dollar's direction will be driven by positioning and any weekend geopolitical risk premium.

Technical Picture:

GBP/USD: Resistance at 1.3388 (Thursday's high), then 1.3443 (100-day moving average, per Pound Sterling Live). Support at 1.3351 (17 September low), then 1.3320 (late-July lows).
GBP/EUR: Resistance at 1.1650 (near-term shelf, per Pound Sterling Live) and 1.1689 (caps the recovery). Support at 1.1630 (100-day moving average) and 1.1600.
EUR/USD: Resistance at 1.1510, then 1.1550 (pre-FOMC level). Support at 1.1473 (Thursday's low) and 1.1450 (early-August base).
Outlook: All three pairs are technically heavy following the week's central bank repricing; GBP/USD faces the most immediate downside risk given the combined weight of a hawkish Fed and a cautious BoE, while EUR/USD will need a clear catalyst to reclaim 1.1550 before the 29 October ECB meeting.

Today's Calendar:

With no tier-one data on either side of the Atlantic, today's price action will be dominated by end-of-week position-squaring, any post-blackout Fed speaker commentary, and weekend geopolitical risk premium in energy markets.

Outlook:

The path of least resistance for GBP/USD remains lower into next week, with the 1.3320-1.3350 zone the next meaningful support cluster, unless weekend geopolitical developments shift the energy-price narrative or early Fed speakers push back against the dot plot's hawkish signal. EUR/USD faces a similar gravitational pull towards 1.1450 given the widening Fed-ECB rate differential, though a 53% market-implied probability of an ECB hike on 29 October provides a floor; treasurers with USD payables or EUR receivables should consider whether current levels warrant opportunistic cover ahead of what is likely to be a volatile October.
