During the opening Asian trading session of the new week, the British pound maintained its upward momentum against the US dollar, hovering near the 1.3650 level and staying close to the recent high recorded on Friday. Over the past month, the GBP/USD pair has been building a steady uptrend, with persistent dollar softness further reinforcing this price action. The prevailing market narrative is gradually shifting from the dollar's interest rate advantage toward expectations of policy shifts in Washington, providing the pair with more distinct upside momentum.
The US currency has so far failed to mount a meaningful recovery, with the dollar index trading near its weakest level in over three months. Following signs of easing inflation pressures in the United States, market participants have been trimming bets on immediate Federal Reserve rate hikes, thereby reducing the interest rate support that had been underpinning the greenback. Meanwhile, the US Treasury Department announced that beginning in September, it would at least double the size of its long-dated bond buyback operations, a move aimed at improving liquidity in the long-end of the Treasury market and relieving upward pressure on yields. Following the announcement, US long-term Treasury yields declined, further diminishing the dollar's near-term appeal.
In the context of currency pricing mechanics, a fall in Treasury yields typically signals a reduction in the relative return advantage of dollar-denominated assets. This is especially relevant as markets begin to reassess the Fed's future policy trajectory. With dollar bulls lacking fresh catalysts, capital flows have gravitated toward non-US currencies that have demonstrated relative resilience. The pound has been a direct beneficiary of these dollar-side dynamics, with GBP/USD gradually converging on the key technical resistance zone near 1.3660.
However, the dollar's current weakness is not without the potential for reversal. Heightened tensions between the United States and Iran could still pose a shock to global risk appetite. Should the situation in the Middle East escalate further, energy transportation and crude oil supplies may be disrupted, and a renewed rise in international oil prices would add to global inflation pressures. Under such circumstances, demand for the dollar as a traditional safe-haven asset could resurface, which would in turn cap the upside for the pound against the dollar.
Energy prices deserve particular attention. Crude oil not only influences global inflation expectations, but it is also a significant variable in the Fed's assessment of future monetary policy. If oil prices continue to climb on supply concerns, the disinflation process in the US could slow down, or even see intermittent reversals. This would force markets to reassess the likelihood of Fed rate cuts or hikes within the year. For GBP/USD, this implies that the current dollar weakness carries substantial uncertainty, and investors should avoid chasing pound strength solely on the basis of the greenback's recent downtrend.
On the UK side, the pound's current performance largely reflects dollar-side pressure rather than a marked improvement in Britain's economic fundamentals. As the exchange rate approaches its recent high, market attention will increasingly turn to UK inflation, wage growth, and the Bank of England's policy trajectory. Should UK inflation remain sticky, limiting the scope for BoE rate cuts, the pound could continue to enjoy a degree of interest rate support. Conversely, if UK economic data show notable weakness and markets rebuild their bets on BoE easing, the pound's relative advantage may diminish.
US economic data releases this week are set to be a critical determinant of the GBP/USD direction. Market focus will center on the personal consumption expenditures price index, a key gauge of US inflation trends. If the core PCE reading continues to indicate cooling price pressures, the case for further Fed tightening may weaken, keeping the dollar under pressure and potentially offering the pound a breakout opportunity. On the flip side, if the PCE report reasserts inflation resilience, reinforced by rising energy costs, the dollar could regain its footing.
In addition, remarks from Federal Reserve Chair Kevin Warsh at the Jackson Hole symposium are expected to carry a high degree of market sensitivity. Participants will be looking for policy signals regarding the future rate path, inflation risks, and labor market conditions. Should Warsh strike a dovish tone, markets may further compress the dollar's rate premium, raising the probability of a GBP/USD break above recent highs. If he instead emphasizes inflation risks and delivers a more hawkish message, the dollar could stage a rebound.
On the daily chart, GBP/USD has maintained an uptrend for nearly a month, with price consistently trading above the key moving average system, keeping the overall bias bullish. The current supply zone near 1.3660 represents a crucial hurdle that determines whether bulls can open up additional upside room. A decisive break above 1.3660 with a solid close above that level could see the pair target the 1.3700 and 1.3750 regions in the next phase. On the downside, immediate support lies at the 1.3600 round figure, followed by support near 1.3570. As long as price holds above 1.3570, the daily bullish structure remains intact.
On the 4-hour timeframe, GBP/USD is trading within a rising channel in the near term, with price making higher highs and higher lows. The short-term moving averages continue to provide support, and the MACD indicator remains in a relatively strong zone. However, as price approaches 1.3660, short-term momentum has entered a phase where breakout confirmation is required. If the pair pulls back to 1.3600 and quickly attracts buying interest before pushing back above 1.3660, a fresh leg higher could be confirmed. Conversely, repeated failures at 1.3660 may trigger profit-taking, pulling price back toward the 1.3570 to 1.3600 area to seek fresh support. As such, the near-term trading approach is better suited to watching for breakout confirmation rather than blindly chasing strength.
In summary, GBP/USD remains in a broadly firm posture, with the persistent dollar weakness, falling Treasury yields, and reduced market expectations for immediate Fed tightening serving as the primary drivers behind the pound's appreciation against the dollar. On the technical front, 1.3660 is the key level that bulls must clear; if price manages to hold above it, the upside potential could expand further. However, Middle East tensions, oil price movements, and the US PCE inflation data all have the ability to alter the dollar's near-term path. Over the coming sessions, the question of whether GBP/USD transitions from range-bound strength to a genuine breakout will hinge on US inflation figures and Fed policy signals. If the dollar remains soft, the pound may extend its month-long rally; if safe-haven demand revives the dollar, the pair could first experience a technical pullback.
