GBP/USD Q4 Outlook: Can the Pound Turn the Tide Against a Hawkish Fed?

By: Fiona Cincotta, Senior Market Analyst

GBP/USD has fallen just 0.5% across the third quarter. While the pair booked solid gains in July and August, those were unwound in September with the pair falling over 2%. The sharp decline in GBP/USD in September came as the U.S. dollar staged a powerful recovery, but the pound also weakened against major peers, including the Japanese yen, Australian dollar and Canadian dollar. The pound rose modestly against the euro, New Zealand dollar and Swiss franc.

The balance of risks points to a downside bias for the pound against the U.S. dollar across the final quarter of the year, as widening Fed-BoE policy divergence continues to support the USD.

Pound Outlook

Inflation

Headline UK inflation rose to 3.1% annually in August, its highest level since March. The increase comes amid the direct effect of higher energy prices from the Middle East conflict. Brent crude prices have fluctuated from lows of around $70 to well over $110 per barrel during the quarter, while natural gas prices have also risen sharply.

As a result, fuel prices have increased significantly, while the Ofgem energy price cap will rise by almost 4% in October.

The Bank of England's latest near-term inflation forecast points to CPI inflation rising to around 3.7% in Q4 2026 and 4.2% in Q1 2027.

Meanwhile, core inflation, which excludes more volatile components, remained at 2.6% in August, while services inflation also remained unchanged at 3.4%. So far, there has been little evidence that firms are passing higher energy costs through into broader prices, meaning second-round effects have yet to become a major concern.

However, food-price inflation is expected to rise in the coming months, adding another potential source of pressure after droughts in the UK over the summer and as Super El Nino hits.

GDP and Labour Market

UK GDP grew by a stronger-than-expected 0.4% month on month in July, following growth of 0.4% in Q2. The OECD forecast growth of 1.1% in 2026 and 1% in 2027. Notably weaker than the growth expected in the US,

The labour market, however, has shown signs of slowing. Vacancies have fallen to their lowest level in five years, while wage growth has also moderated.

Weak UK labour demand, combined with sluggish economic growth momentum, could weigh on GBP and highlight the policy challenges the BoE faces.

Bank of England Outlook

Markets are pricing significant tightening from the Bank of England between now and July 2027. However, higher energy prices create a difficult policy mix. While inflation risks are rising, growth momentum faces a challenging outlook, leaving the pound vulnerable as the policy trade-offs become more acute.

The Bank of England left interest rates unchanged at 3.75% for a sixth straight meeting in September, with the vote split remaining 6-3. Governor Andrew Bailey warned that inflation risks remained to the upside, while stressing that there was still limited evidence of second-round inflation effects. The Bank has made clear that a prolonged period of elevated energy prices could eventually require higher rates.

According to the OECD, the Bank of England does not need to raise rates further because policy is already restrictive enough to bring inflation back towards target.

This contrasts with market expectations and raises the possibility that rate-hike expectations have become too aggressive. If so, the pound could come under further pressure as markets unwind some of those hawkish bets.

Political Uncertainty

With Prime Minister Andy Burnham now in power, attention is turning to Chancellor John Healey's Budget on October 28.

The Budget comes against a backdrop of surging gilt yields, with the 10-year yield around 5.38%, putting further pressure on public finances and narrowing fiscal headroom.

The rise in yields reflects persistent global inflation concerns, but the UK debt profile remains particularly vulnerable to higher borrowing costs. Recent borrowing data showed the fiscal year deficit running £8.1 billion above the OBR's forecast, while higher debt-servicing costs have reduced the government's room for manoeuvre.

Without significant tax rises or spending restraint, the Chancellor faces a difficult fiscal balancing act, which could add another source of uncertainty for sterling.

USD Outlook

The U.S. economy has remained remarkably resilient despite the ongoing conflict in the Middle East, rising energy prices, tariffs and inflationary pressures.

September U.S. PMI data showed private economic activity expanding at its fastest pace in five years.

Meanwhile, labour-market conditions remain relatively healthy, with 162,000 jobs added in August and expectations for another 100,000 in September.

The concern is not about a weaker jobs market but that the labour market could be too strong, adding to demand and potentially keeping inflation elevated.

Inflation is also proving sticky. CPI came in at 3.4% in August, while core inflation was hotter than expected. The Fed's preferred inflation gauge, core PCE, is also expected to remain at 3.4%, well above the 3% target level.

Federal Reserve Rate Hikes

The Fed raised rates by 25 basis points in September to 3.75%-4.00%, while markets are pricing in around a 70% chance of another hike in October. Fed officials have also continued to stress the need for further hikes to keep inflation under control.

The possibility of further rate hikes has helped drive the U.S. dollar to a two-month high.

The U.S. Federal Reserve is therefore looking increasingly hawkish, while the Bank of England is still questioning whether further tightening is necessary.

The widening Fed-BoE policy divergence remains the strongest argument for further GBP/USD weakness in Q4.

However, there is a potential reversal to this trade. Should the war in the Middle East end, a sharp fall in oil prices could ease U.S. inflationary pressures. If this feeds through to core PCE and weaker rate expectations, markets could begin scaling back Fed tightening bets.

That would remove one of the dollar's largest sources of support and could allow GBP/USD to recover.

GBP/USD Scenarios

The balance of risks points towards a weaker pound and a stronger U.S. dollar over the coming quarter.

Despite rising UK headline inflation, core inflation and services inflation are not yet showing significant second-round effects, while the UK labour market is deteriorating. Political uncertainty and weaker domestic growth could also limit the scope for an aggressive BoE hiking cycle.

The U.S. economy, by contrast, continues to show resilience, while inflation remains elevated and markets are increasingly pricing further Fed tightening.

For GBP/USD, the key variable may ultimately be oil. A sustained rise in energy prices would reinforce inflation pressures, support higher U.S. yields and strengthen the dollar. A significant decline in oil prices could do the opposite, pulling USD lower and provide a tailwind to GBP/USD.

GBP/USD Technical Analysis – Weekly Chart

image-20260929131751-2

GBP/USD continues to trade in a broad consolidation range, capped on the upside around 1.37 and supported around 1.3150.

The price has broken below the 50 EMA and the multi-year rising trend line. Combined with an RSI below 50, this keeps sellers hopeful of further downside.

Sellers would need to break below 1.3150 and the 200 EMA around 1.31 for downside momentum to accelerate towards 1.30. Below here, 1.25 comes into focus.

On the upside, 1.34 is a key level, where the rising trend line and 50 EMA now converge. A rise above 1.37 would create a higher high and break the pair out of the range in which it has traded since June 2025.
