British Pound ticks up as Iran diplomacy hopes curb USD rally following hot US CPI

Hopes of a US-Iran peace agreement restrain the safe-haven USD, drawing buyers to GBP/USD on Wednesday.
Sterling receives further backing from the BoE’s hawkish outlook, supporting spot prices.
50 bps Fed rate hike prospects for December support USD bulls and should constrain the pair’s gains.

GBP/USD trades near 1.3350. The pair inches up in Wednesday’s Asian session, recovering from the one-and-a-half-week low around 1.3300 reached a day earlier. However, the fundamental picture calls for caution before positioning for a substantial advance.

Optimism over a possible diplomatic settlement to end the US-Iran war is restraining the safe-haven US Dollar (USD), lending support to GBP/USD. At Tuesday’s G7 meeting, US Secretary of State Marco Rubio said major combat operations in Iran were unnecessary. His remarks followed comments on Monday from President Donald Trump, who said the US was maintaining the status quo in the Iran war because he currently saw no reason to escalate it.

Further support for the British Pound (GBP) and GBP/USD comes from the Bank of England’s (BoE) hawkish outlook, which signals that second-round inflation effects could necessitate additional tightening. In the US, Tuesday’s strong consumer inflation readings reinforced the likelihood of a Federal Reserve (Fed) rate increase in December. Several Fed officials, including Governor Christopher Waller, also raised the possibility of a larger 50-basis-point (bps) increase.

50 bps December hike risk: Waller bolsters Dollar bulls

A 9/10 FXS Speechtracker score puts Fed Governor Waller’s distinctly more hawkish remarks well above his historical average of 7.3/10, highlighting a clear preference for further tightening. He explicitly left open a half-point FED rate increase in December if October core CPI comes in around 0.3% or higher. Even with better data, he supports at least a quarter-point increase. That combination indicates a low threshold for further hikes and a forceful policy response to any upside inflation surprise. His focus on widespread price pressures, the insufficient restrictiveness of current policy and the need for higher real rates strengthens upside risks to US yields. It also supports the Dollar through the prospect of diverging monetary policies.

A 3.17-point increase took the FXS Fed Sentiment Index to 145.50, firmly anchoring the Fed’s stance in hawkish territory and confirming the above-baseline FXS Speechtracker reading. With the index so far above the neutral 100 mark, markets should assign a greater probability to continued rate rises and a firmer Dollar heading into the December meeting.

The resulting advantage for USD bulls suggests that corrective declines in the currency are more likely to attract buyers and stay contained. Strong follow-through buying would therefore be needed before concluding that GBP/USD’s recent retreat following rejection at the psychological 1.3500 level has ended, and positioning for a renewed advance from the year-to-date low reached in October.

4-hour GBP/USD chart

Technical Outlook

On the 4-hour chart, a constructive base under GBP/USD is provided by the 50.0% Fibonacci retracement and the 200-period Simple Moving Average (SMA), with the pair trading just above both. However, nearby Fibonacci resistance at 1.3365 limits gains, leaving the short-term outlook neutral.

The first upside hurdle is the 38.2% retracement at 1.3365. Beyond that lies stronger resistance at the 23.6% level near 1.3419. Initial downside support sits at the 50.0% retracement of 1.3322, backed by the 200-period SMA at 1.3314. A break beneath these levels would bring the 61.8% Fibonacci retracement at 1.3279 into view. Should selling intensify, further support lies at 1.3217 and 1.3138.

Pound Sterling: Frequently Asked Questions

Pound Sterling: what defines the currency?

Dating back to 886 AD, the Pound Sterling (GBP) is the world’s oldest currency and the United Kingdom’s official currency. Figures for 2022 place it fourth among the world’s most traded foreign exchange (FX) currencies, representing 12% of all transactions and average daily turnover of $630 billion. Among its principal trading pairs, GBP/USD, known as ‘Cable’, accounts for 11% of FX. GBP/JPY, which traders call the ‘Dragon’, represents 3%, while EUR/GBP accounts for 2%. The Bank of England (BoE) issues the Pound Sterling.

Bank of England policy: how does it affect the Pound Sterling?

Monetary policy set by the Bank of England is the strongest influence on the Pound Sterling’s value. Decisions hinge on whether the BoE has met its principal objective of “price stability”, meaning a steady inflation rate of around 2%. Interest rate adjustments are its main means of achieving that goal. To curb excessive inflation, the BoE seeks to raise borrowing costs for households and businesses by increasing interest rates. Sterling generally benefits, since higher rates make the UK a more appealing destination for global investors’ funds. Inflation that falls too low, by contrast, signals slowing economic growth. The BoE would then consider cutting rates to lower the cost of credit, encouraging businesses to borrow more for investment in projects that generate growth.

Economic indicators: what drives the Pound’s response?

Sterling can respond to economic releases because they indicate the economy’s health. GDP, Manufacturing and Services PMIs, and employment figures are among the indicators that can shape GBP’s direction. Economic strength supports Sterling by drawing in more overseas investment. It may also prompt the BoE to raise interest rates, directly strengthening GBP. Weak economic figures, conversely, are likely to weigh on the Pound Sterling.

Trade Balance: why does it matter for the Pound?

The Trade Balance is another important release for Sterling. Over a specified period, it measures the gap between a country’s export earnings and its spending on imports. Strong overseas demand for a country’s exports generates additional demand for its currency as foreign buyers seek to purchase those goods. A positive net Trade Balance therefore strengthens the currency, while a negative balance has the opposite effect.
