Risk Sentiment Warms and Central Bank Decisions Loom: GBP/USD Faces Multiple Tests
Introduction
On Monday (June 15) Asian session, GBP/USD rallied about 0.3% to around 1.3445. Behind this rise, the news of a US-Iran deal significantly boosted market risk appetite, pushing risk-sensitive currencies like the pound higher. Meanwhile, global investors are holding their breath for the latest monetary policy decisions from the Fed and the BoE this week, with volatility expectations rising sharply.
Geopolitical Risk Easing Boosts Risk Assets
The US-Iran deal has drawn a phase-ending line under months of Middle East tension, with market sentiment notably improved. Nerves that had been taut due to escalating conflict relaxed, and funds quickly moved from safe havens to risk assets. Asian stocks generally rose, with major markets like Japan, South Korea, and Australia recording decent gains, fully reflecting strong investor risk appetite.
Meanwhile, the US dollar index fell 0.4% to around 99.40, extending its recent weakness due to cooling US inflation data and rising Fed rate cut expectations. The weaker dollar further supported high-risk currencies like the pound and Australian dollar.
Notably, the improvement in market sentiment was particularly evident in oil prices. As a barometer of geopolitical risk, Brent crude and WTI crude futures both fell over 4% in early Asian trade on Monday, indicating the market is rapidly stripping out the risk premium previously embedded in oil prices. Analysts pointed out that the reopening of the Strait of Hormuz will release millions of barrels of crude supply per day, effectively easing the tension in the global energy market.
Pakistan Prime Minister Shehbaz Sharif confirmed on social media that a memorandum of understanding between the US and Iran will be formally signed in Switzerland on June 19. This clear timeline further consolidates market confidence in the peace process. Sharif's role as a key mediator adds important endorsement to the agreement's authority.
The market is now closely watching the specific arrangements for the signing ceremony and the progress of discussions on core issues such as Iran's nuclear program and sanctions relief during the subsequent 60-day negotiations. Analysts believe that if follow-up talks proceed smoothly, the global geopolitical risk premium could fall further, providing sustained support for risk assets.
Key Events Line Up This Week
Meanwhile, investors are preparing for a week of heightened volatility, especially for pound traders. This week, the UK will become the focus of the global forex market, with a series of heavyweight economic data and central bank decisions due.
First, the UK will release the labor market report for the three months to April. The market is widely focused on wage growth and unemployment changes—two key indicators for the BoE to judge domestic inflation pressures. If wage growth remains high, it will strengthen expectations for the BoE to maintain a hawkish stance, thus supporting the pound; conversely, if the labor market shows clear signs of cooling, it could weaken the pound's upward momentum.
Second, the May CPI data is also highly anticipated. Although global energy prices have fallen recently due to the easing Middle East situation, UK services inflation remains sticky. The market expects the May CPI year-on-year increase may still be above the BoE's 2% target. If inflation data surprises to the upside, it will increase pressure on the BoE to continue tightening policy.
Most critically, the BoE's monetary policy statement is due. The market widely expects the BoE to keep rates unchanged, but investors will closely watch Governor Bailey's tone and the vote split. Any hints about future rate cut timing or further rate hikes could trigger sharp pound volatility.
In the US, investors will focus on the Fed's monetary policy decision on Wednesday. Although the market generally expects the Fed to hold steady, with inflation returning above 4% and bond markets pricing in rate hikes ahead, Fed Chair Warsh's comments at his first press conference will be a key variable for global markets. The market will scrutinize every word of the statement for clues about the future rate path.
Analysts point out that if the Fed sends a hawkish signal, the dollar could gain support, putting pressure on the pound; conversely, if Warsh shows compromise to the White House's rate cut demands, the dollar could weaken further, providing upside for the pound. The policy signals from both central banks will create cross-impact this week, with GBP/USD facing two-way volatility risks.
Divergent Institutional Views
Brown Brothers Harriman's research team holds a clearly bearish view on GBP/USD, predicting the pair will fall to 1.3100, a potential decline of over 1%. The core logic is that US economic growth prospects are significantly better than the UK.
BBH analyst Elias Haddad noted that UK April GDP fell 0.1% month-on-month, the first monthly contraction since August 2025, mainly dragged by a decline in services output. PMI data suggests UK Q2 real GDP may contract 0.2% quarter-on-quarter, below the BoE's baseline forecast of +0.1%. Meanwhile, swap curves have sharply lowered BoE rate hike expectations over the next 12 months from 60 bps to 40 bps.
In addition, BBH warned that UK political risks could intensify pound downside pressure. The June 18 by-election in Makerfield is closely watched, with polls showing Labour candidate Andy Burnham leading Reform UK by 10 percentage points. His return to parliament could challenge Prime Minister Starmer's leadership. A Burnham-led Labour government could increase spending and borrowing, worsening UK fiscal credibility. Technically, 1.3100 is a key support area; if broken, it could open the door to the 1.3000 level.
Scotiabank strategists Shaun Osborne and Eric Theoret hold a neutral-to-bearish stance on GBP/USD, believing the pair is consolidating recent gains around 1.3400, awaiting guidance from this week's key data and the BoE decision.
Scotiabank noted that UK April GDP was in line with expectations, while industrial production and trade data were slightly disappointing. Domestic risks remain high this week: CPI data Wednesday, employment data Thursday, with the BoE rate decision and Labour by-election on the same day. The market widely expects the BoE to keep rates unchanged, but the risk lies in the MPC statement and rate outlook guidance—the market currently prices in about 35 bps of tightening by year-end. Political risk is elevated due to the by-election result.
Technical Analysis: Range-Bound Awaiting Breakout
According to the GBP/USD daily chart, the pair is in a range-bound pattern. Prices have oscillated within the 1.3302-1.3657 range, currently near the medium-term moving averages, with bulls and bears in a tug-of-war.
On the moving average system, prices are almost flat with MA20, MA50, MA100, and MA200, forming a sticky state, indicating unclear direction and lack of a clear trend. Upside resistance is concentrated in the 1.3450-1.3470 area, with further resistance at the 1.3657 previous high; support is around the 1.3300-1.3302 zone, with a key defense at the 1.3159 low.
In terms of indicators, the MACD two lines are converging around the zero line, with the histogram near zero, showing weak momentum from both bulls and bears; RSI is around 52 in neutral territory, with no overbought or oversold signals, further confirming the current range-bound characteristics.
Conclusion
Overall, GBP/USD is under the cross-influence of multiple factors. The US-Iran deal provides short-term support for risk assets, but this week's Fed and BoE decisions will be the core variables determining the pair's direction. Employment and inflation data will affect central bank policy expectations, while the UK Labour by-election result could bring additional political risk premium.
Technically, the pair is in a range-bound pattern.
