GBP/USD Holds Near 1.34 as Oil Shock Revives Fed and BoE Rate Risks

GBP/USD Starts the Week Near 1.34

GBP/USD began the week close to $1.339, showing only a limited reaction to renewed fighting between the United States and Iran. The dollar initially strengthened as oil prices jumped, but later surrendered part of its advance. The dollar index fell back to around 100.83, while sterling remained broadly unchanged.

The muted movement does not mean the new geopolitical escalation is unimportant. It means the oil shock is influencing both sides of GBP/USD.

A higher oil price can support the dollar through safe-haven demand and renewed Federal Reserve tightening expectations. At the same time, Britain is a large energy importer, so higher oil and gas costs can lift UK inflation and keep the Bank of England cautious about leaving interest rates unchanged for too long.

Oil Prices Have Reintroduced the Inflation Trade

Brent crude rose around 3% to $78.50 a barrel after U.S. and Iranian forces exchanged missile and drone attacks and Tehran again claimed that the Strait of Hormuz had been closed. Although U.S. officials said commercial vessels were still being escorted through the waterway, shipping activity had slowed sharply.

The immediate currency effect favoured the dollar. Higher energy prices raise global inflation risks and make it more difficult for the Fed to relax policy. Fed funds futures were assigning an implied probability of about 50% that the Fed would deliver at least two rate increases by its December meeting.

That pricing gives the dollar a rate advantage over sterling. Even when GBP/USD does not fall sharply, stronger expectations for U.S. tightening can prevent the pair from extending a recovery.

The Dollar Is Supported, but It Is No Longer an Easy One-Way Trade

The dollar rallied during the earlier phase of the Middle East conflict, but it now starts from a much stronger position. The market has already repriced the Fed toward a more restrictive path, meaning a renewed rise in geopolitical risk may not produce the same scale of dollar gains as before.

The next test will come from U.S. inflation data and Federal Reserve communication. June CPI is due on Tuesday, followed by producer-price data and congressional testimony from Fed Chair Kevin Warsh. The market will be watching whether the latest oil increase reinforces the case for further tightening or is treated as another temporary supply shock.

For GBP/USD, the distinction is important. Persistent inflation and stronger Fed guidance would favour the dollar. A softer CPI report or a cautious Fed message could reduce rate-hike pricing and allow sterling to recover.

BoE Rate Expectations Give Sterling a Floor

The pound also has monetary-policy support. Bank of England Chief Economist Huw Pill said on 9 July that UK interest rates would need to rise to contain inflation pressure. Pill said he was concerned that demand had been running somewhat stronger than the economy’s supply capacity.

Pill was one of two members of the nine-person Monetary Policy Committee who voted to raise Bank Rate from 3.75% at the June meeting. The next BoE decision is scheduled for 30 July.

This gives sterling an important defensive advantage. The BoE is not signalling that an easing cycle is about to begin. Instead, the debate has shifted toward whether another rate increase will be required if energy costs pass through to wages and domestic prices.

Higher Oil Is Not Automatically Positive for the Pound

A potential BoE rate increase may support sterling through yield expectations, but the reason behind the increase matters.

The BoE has already warned that Middle East energy disruption can raise motor-fuel and utility bills, force businesses to increase prices, and encourage workers to demand higher wages. UK inflation currently stands at 2.8%, above the BoE’s 2% target, and the central bank expects inflation to rise again during the year.

However, imported inflation is not the same as strong domestic growth. If the BoE raises rates because energy prices are squeezing household budgets, the higher yield may support the pound initially, but tighter borrowing conditions and weaker consumption can eventually restrict sterling.

The current setup therefore differs from a normal growth-driven rate-hike cycle. The pound has policy support, but the UK economy may struggle with the same forces that make higher rates necessary.

The UK Growth Picture Remains Uneven

Britain’s economy expanded by 0.6% in the first quarter of 2026, with services providing the largest contribution. However, the stronger headline number concealed pressure on households and signs that momentum weakened after the quarter ended.

Real household disposable income per person fell 0.8% during the first quarter, while the household saving ratio dropped to 8.9%. Economists also warned that softer spending, tighter financial conditions and economic uncertainty could weigh on investment.

These figures limit the extent to which BoE tightening can become an uncomplicated bullish driver for GBP/USD. A higher policy rate can support sterling against the dollar, but weaker purchasing power makes the British economy more sensitive to additional borrowing costs.

Fiscal Uncertainty Adds Another Limitation

Sterling is also entering a politically important period. Andy Burnham is expected to become Labour leader on 17 July and prime minister on 20 July, leaving markets focused on the incoming government’s fiscal approach. The pound eased to around $1.3381 as the week began.

Britain’s Office for Budget Responsibility has warned that public debt is on an unsustainable long-term path under most of its scenarios. It estimated that stabilising debt near its current level would require a permanent improvement in the primary budget balance equal to 3.8% of GDP in the 2031/32 financial year.

This does not create an immediate sterling crisis, but it narrows the incoming government’s room to use fiscal stimulus to offset high interest rates and energy pressure. For currency markets, the result is that political optimism must be balanced against the need to preserve fiscal credibility.

What Is Driving GBP/USD Now

GBP/USD is currently being pulled by four connected forces.

The first is the renewed oil shock, which supports the dollar through inflation and safe-haven demand.

The second is the Fed outlook. Markets are again considering multiple U.S. rate increases, but upcoming CPI data will determine whether that pricing can be sustained.

The third is the BoE. Hawkish comments from Huw Pill and the existing 3.75% Bank Rate give sterling a policy floor.

The fourth is the UK economy. Weak household finances, uncertain growth momentum and limited fiscal space prevent the pound from turning that policy support into a clean bullish trend.

Near-Term View

The near-term GBP/USD bias is balanced but fragile.

The pair could remain supported around recent levels if the BoE keeps the possibility of a July increase alive and U.S. inflation comes in softer than expected. Lower oil prices or a reopening of normal traffic through the Strait of Hormuz would also reduce defensive demand for the dollar.

Sterling could come under renewed pressure if the oil rally continues, U.S. inflation strengthens Fed tightening expectations, or the incoming British government creates doubts about fiscal discipline.

The important point is that oil now affects both currencies through different channels. It strengthens the dollar immediately, but it can also increase BoE tightening expectations. That makes GBP/USD more likely to trade with sharp two-way moves than follow a simple geopolitical direction.

Conclusion

GBP/USD remains close to 1.34 because neither side has a complete advantage.

The dollar is supported by renewed Gulf conflict, higher oil prices and the possibility of additional Fed rate increases. Sterling is supported by a Bank of England that is still debating tighter policy, with Huw Pill explicitly stating that rates will need to rise.

However, Britain’s weak household position, uneven growth and fiscal constraints limit how far the pound can benefit from higher rate expectations. GBP/USD therefore looks more like a policy-driven range than the start of a clean sterling rally or a one-way dollar advance.
