Hopes for Iran diplomacy curb hot US CPI-driven USD rally as British Pound inches higher

Buying interest supports GBP/USD on Wednesday, with hopes of a US-Iran peace agreement restraining the safe-haven USD.
Further backing for the GBP and spot prices comes from the BoE’s hawkish policy outlook.
The prospect of an outsized 50 bps Fed rate increase in December supports USD bulls and should limit the pair’s gains.

A modest recovery in GBP/USD during Wednesday’s Asian session takes the pair further above the one-and-a-half-week low near 1.3300 recorded a day earlier. Despite spot prices now trading around 1.3350, the fundamental backdrop calls for caution before taking positions for a substantial advance.

Hopes of a diplomatic settlement to end the US-Iran war continue to support GBP/USD by limiting demand for the safe-haven US Dollar (USD). Speaking at a G7 meeting on Tuesday, US Secretary of State Marco Rubio said major combat operations in Iran were unnecessary. His remarks came after President Donald Trump said on Monday that the US was maintaining the status quo in the Iran war, as he currently saw no reason to escalate it.

The British Pound (GBP), and consequently GBP/USD, also draws support from the Bank of England’s (BoE) hawkish outlook, which indicates that second-round inflation effects could necessitate additional tightening. On the US side, however, Tuesday’s strong consumer inflation readings reinforced the likelihood of a Federal Reserve (Fed) rate increase in December. Some Fed officials, including Governor Christopher Waller, also raised the possibility of a larger increase of 50 basis points (bps).

Could Waller’s Warning of a Larger December Hike Further Support the Dollar?

A 9/10 FXS Speechtracker score, well above the historical average of 7.3/10, highlighted the distinctly more hawkish tone of Fed Governor Waller’s remarks and his clear preference for further tightening. He explicitly left open a half-point Fed rate increase in December if October core CPI comes in at around 0.3% or higher, while backing at least a quarter-point increase even if the data improves. This suggests a low threshold for further hikes and a forceful policy response to any upside inflation surprise. By stressing widespread price pressures, the insufficiently restrictive stance of current policy and the need for higher real rates, Waller reinforced upside risks to US yields and lent support to the Dollar through the prospect of relative policy divergence.

An increase of 3.17 points took the FXS Fed Sentiment Index to 145.50, confirming the Fed’s firmly hawkish position and supporting the above-baseline FXS Speechtracker assessment. With the index so far above its neutral level of 100, the reading suggests markets should assign a greater probability to further rate increases and a stronger Dollar heading into the December meeting.

USD bulls therefore retain an advantage, with any corrective decline more likely to attract buyers and remain shallow. Before concluding that the recent fall following rejection at the psychological 1.3500 level has ended, it would be prudent to await strong follow-through buying. Such confirmation would also be needed before positioning for GBP/USD to resume its advance from the year-to-date low reached in October.

What Does the GBP/USD 4-Hour Chart Show?

Which Technical Levels Matter for GBP/USD?

A supportive base for GBP/USD is provided by the 50.0% Fibonacci retracement and the 200-period Simple Moving Average (SMA) on the 4-hour chart, with the pair trading just above both. However, nearby Fibonacci resistance at 1.3365 restricts gains, leaving the near-term outlook neutral.

The first hurdle for buyers is the 38.2% retracement at 1.3365; beyond it, the 23.6% level near 1.3419 presents stronger resistance. Initial support lies at 1.3322, the 50.0% retracement, with further backing from the 200-period SMA at 1.3314. Below this area, the 61.8% Fibonacci retracement at 1.3279 would come into focus. If selling intensifies, additional support awaits at 1.3217 and 1.3138.

Common Questions About Pound Sterling

What Are the Key Facts About Pound Sterling?

As the United Kingdom’s official currency, the Pound Sterling (GBP) is also the world’s oldest, dating back to 886 AD. According to 2022 data, it ranks fourth among the most traded currencies in the global foreign exchange (FX) market, representing 12% of all transactions and an average daily volume of $630 billion. Among its principal currency pairs, GBP/USD, known as ‘Cable’, represents 11% of FX trading. GBP/JPY, referred to by traders as the ‘Dragon’, accounts for 3%, while EUR/GBP accounts for 2%. Responsibility for issuing Pound Sterling rests with the Bank of England (BoE).

Why Do Bank of England Decisions Matter for Pound Sterling?

Monetary policy set by the Bank of England has the greatest influence on Pound Sterling’s value. In making its decisions, the BoE assesses whether its core objective of “price stability” has been met, meaning inflation remains steady at around 2%. Interest rate changes are its main means of achieving that objective. Faced with excessively high inflation, the BoE seeks to bring it under control by increasing interest rates, raising borrowing costs for households and businesses. GBP generally benefits because higher rates make the UK a more appealing destination for global investors’ funds. Conversely, inflation that falls too low signals a slowdown in economic growth. The BoE would then consider cutting interest rates to reduce credit costs, encouraging businesses to borrow more and invest in projects that generate growth.

Which Economic Indicators Can Move the Pound?

By revealing the economy’s health, economic releases can affect Pound Sterling’s value. GDP, Manufacturing and Services PMIs, and employment figures are among the indicators capable of shaping GBP’s direction. Sterling benefits from economic strength, which attracts greater foreign investment and may also prompt the BoE to raise interest rates, directly strengthening GBP. Weak economic readings, by contrast, are likely to weigh on Pound Sterling.

Why Is the Trade Balance Important for the Pound?

The Trade Balance is another important release for Pound Sterling. Over a specified period, it records the difference between a country’s export earnings and its expenditure on imports. Strong overseas demand for a country’s exports creates 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.
