GBP/USD Swings as Oil and War Drive Markets

GBP/USD faced significant pressure, dipping to $1.3223 during the Asian session. However, a recovery ensued, lifting Cable above $1.3400 following Trump’s announcement of a ceasefire in Iran, which led to a sharp decline in the USD and a resurgence of risk appetite in the markets. The intraday range — from $1.3223 to $1.3457 by mid-session — encapsulates the complete psychological struggle that GBP/USD has been engaged in over the past several weeks within a single trading session. The FTSE 100 experienced a decline of 0.24%, settling at 9,894. The GBP/EUR exchange rate was noted at 1.1560, while the DXY retreated from its intraday peak exceeding 100.06 to around 98.83. This dollar weakening contributed to a rise in Cable, despite the ongoing deterioration of the UK’s fundamental economic landscape. Prior to Trump’s announcement, Sterling was trading 0.5% lower against the dollar, falling below the $1.33 threshold—a level that has served as a psychological support for a currency pair whose story has been fundamentally altered by the Iran conflict and the Bank of England’s significant shift from a rate-cutting stance to one that may embrace aggressive hikes. The market had anticipated two rate cuts from the Bank of England prior to the onset of the war on February 28. As of Monday, the market is anticipating four quarter-point BoE rate hikes this year — a shift of 150 basis points in expected policy direction over 23 days that signifies one of the most dramatic repricing events in UK rate expectations since the 1992 ERM crisis. To comprehend GBP/USD at this moment, one must analyze the reasons behind the recent repricing, assess its justification, and evaluate the technical framework to determine the potential trajectory of Cable from the existing $1.3398 level.

The Bank of England maintained its rates at 3.75% during the March meeting last week — a choice that aligned with forecasts, yet the accompanying guidance was far from standard. Governor Andrew Bailey clearly described the Middle East conflict as a “shock to the economy” that is expected to drive inflation significantly higher in the short term. He emphasized that ensuring safe shipping through the Strait of Hormuz is “key to addressing energy price rises.” The two statements indicate that the BoE recognizes its monetary policy trajectory is now subject to a geopolitical factor beyond its control. The bank is currently contending with increasing inflation due to the energy shock while also experiencing a slowdown in growth stemming from the same energy shock — a quintessential stagflationary predicament that no central bank desires to manage. Forecasts from JP Morgan and Barclays indicate that two rate hikes from the BoE are anticipated this year, with the initial increase projected for April. The market has advanced, now reflecting expectations for four quarter-point increases — suggesting the BoE may elevate rates from 3.75% to 4.75% by the end of the year. The forecast incorporates a situation in which the energy price effects of the Iran conflict elevate headline UK CPI to 5% or higher, compelling the Bank of England to initiate a stringent tightening cycle despite a contracting UK economy. Economists in the UK, as surveyed by Reuters, anticipate that the forthcoming CPI reading will reveal headline inflation at 3% for February, prior to the complete effect of the war’s energy prices being felt. Additionally, core CPI is projected to be at 3.1%, exceeding the Bank of England’s target of 2%. By April and May, as the energy shock becomes fully integrated into the price index, those figures are anticipated to rise significantly. The BoE’s decision to raise rates amid a decelerating economy does not favor growth for Sterling. However, in the near term, a hawkish stance from the BoE reduces the interest rate gap compared to the Fed’s 3.75%, offering some relative yield support for GBP/USD when the pair is in need of any fundamental backing it can secure.

The price movement observed on Monday for GBP/USD provided valuable technical insights. The pair began with a downward gap and hovered around $1.3335 during the Asian session, influenced by the demand for the dollar as a safe haven, while oil prices exceeded $100 and equity markets experienced a significant decline ahead of the U.S. trading hours. The pair maintained its position above the significant $1.3223 support level — the March low that signifies the lower limit of the ongoing corrective structure — and upon the announcement from Trump, Cable rebounded sharply above $1.3400, approaching the 200-day simple moving average that has been functioning as a dynamic resistance. The fact that 1.3223 held on two separate tests — both the earlier intraday low and the prior week’s extreme — is technically meaningful. Double bottoms at the same support level, confirmed by a recovery above $1.3400, establish the structural precondition for the falling wedge and inverted head-and-shoulders patterns that numerous technical analysts are currently identifying as potential reversal setups. The daily chart shows that the Percentage Price Oscillator has established a bullish crossover pattern, indicating momentum that has historically led to notable recoveries in Cable during previous cycles. The RSI, currently around 45, is positioned below the neutral 50 midline, indicating a cautiously bearish sentiment. However, the fact that the RSI is forming higher lows while the price is testing established support suggests a classic positive divergence setup, often seen before a potential trend exhaustion in the bearish direction. None of this indicates a confirmed reversal — the pair continues to trade below the flattening 100-day exponential moving average and remains beneath the middle of the Bollinger Band, which keeps it anchored in the lower half of the volatility envelope. The technical indicators suggest that the downside momentum is waning, warranting attention for a potential breakout above the key resistance zone of $1.3430-$1.3470.

The concurrent emergence of a falling wedge pattern alongside an inverted head-and-shoulders on the GBP/USD daily chart warrants greater analytical consideration than it is presently afforded by markets preoccupied with macroeconomic narratives. A falling wedge represents a bullish reversal pattern characterized by two converging downward-sloping trendlines. This formation indicates that selling pressure is diminishing and losing momentum, as each subsequent lower high and lower low occurs in smaller increments until the pattern culminates in a breakout. The falling wedge pattern exhibits its strongest potential when it emerges following a prolonged downtrend — a scenario that accurately describes the current situation, as Cable has declined from a peak of $1.3470 to a trough of $1.3223 within a short period, influenced by heightened dollar demand due to the Iran conflict and concerns over stagflation impacting Sterling. The inverted head-and-shoulders pattern observed within the same timeframe provides an additional layer of structural bullish confirmation. An inverted head-and-shoulders pattern features a left shoulder around $1.3300, a head at $1.3223, and a right shoulder developing near the $1.3300-$1.3320 range. This pattern is recognized as one of the most statistically reliable reversal formations in technical analysis, with the completion signal necessitating a break and close above the neckline. The neckline of the inverted head-and-shoulders pattern for GBP/USD aligns closely with the $1.3430 resistance level, which corresponds to the Bollinger Band middle cluster and the 100-day EMA.

A daily close above $1.3430 would confirm the break of the inverted head-and-shoulders neckline and the breakout from the falling wedge, establishing a dual-pattern confirmation that targets $1.3500 as the immediate objective and potentially $1.3560 as the extended target. The stop for any long position based on these patterns is positioned at $1.3225 — slightly beneath the inverted head-and-shoulders head, which marks the invalidation point of the pattern. One of the most significant fundamental observations for GBP/USD is that the Fed funds rate and the Bank of England policy rate are currently the same — both at 3.75%. This represents a distinctive historical setup that eliminates the straightforward yield differential rationale that has been propelling dollar strength relative to the majority of other G10 currencies. The EUR/USD pair is currently at a 160 basis point disadvantage, with the ECB rate at 2.15% compared to the Fed’s rate of 3.75%. GBP/USD does not encounter any such disadvantage at the present rate levels. The strength of the dollar against Sterling is influenced not by yield differentials but rather by the petrocurrency premium associated with the dollar. This phenomenon arises as surges in oil prices now favor the dollar, given that the U.S. holds the position of the world’s largest oil producer and exporter. At the time when Brent reached $114 and WTI exceeded $100, the demand for the dollar as a petrocurrency was at its peak. Following Monday’s 10% drop in oil prices, the demand for petrocurrencies diminished in tandem with crude, leading to a recovery in GBP/USD from $1.3223 to $1.3398, despite the Bank of England’s fundamental conditions remaining unchanged over the past day.

The critical implication is that GBP/USD’s path forward is more directly tied to oil prices than to interest rate spreads — which means the pair’s near-term direction will be determined by whether the Iran ceasefire holds and Brent sustains below $105, or whether the five-day diplomatic window collapses and crude spikes back toward $115. In the scenario where the ceasefire holds, the petrocurrency premium of the dollar diminishes, while the expectations for a rate hike by the BoE in April lend yield support to Sterling. Consequently, GBP/USD has the potential to recover towards the range of $1.3500-$1.3560. In the event of a ceasefire failure, we can expect a surge in oil prices, a resurgence of the dollar premium, and Cable may dip below $1.3223, heading towards $1.3160 and possibly reaching the key psychological level of $1.30. The inflation trajectory in the UK, influenced by the Iran war, presents GBP/USD with a paradox that adds layers of analytical complexity compared to other dollar pairs. In a typical inflationary scenario, escalating inflation in the UK compels the Bank of England to raise interest rates, enhancing the yield appeal of Sterling, thereby bolstering GBP/USD. However, the inflation resulting from the Iran war is driven by supply constraints and concurrently hampers growth — it raises prices while undermining economic activity. Farmers in Wiltshire are currently incurring costs of £1.20-£1.30 per litre for red diesel, a significant increase from the previous price of 65p prior to the war. Heating oil has experienced a significant increase, more than doubling in price. The RAC reports that petrol prices have increased by 9%, while diesel prices have surged by 17% at standard filling stations across the UK. These cost increases are not being passed on to workers as wage increases; rather, they represent extractive transfers from household budgets to energy producers.

UK consumers are currently reducing their leisure and dining expenditures by £40 per week, as indicated by official figures for households with a gross income of approximately £55,000. They are now encountering additional pressure from rising energy costs, which are expected to be reflected in food prices in the coming months as the increases in fertilizer costs work their way through the supply chain. The NFU has announced that food price increases are on the horizon. The interplay of elevated energy expenses, increased food prices, and a decline in consumer discretionary spending exemplifies the stagflation scenario that the BoE described as a “shock to the economy.” When a central bank raises rates in such an environment, it fails to tackle the supply-side inflation — it simply increases credit costs alongside energy costs, further squeezing consumer spending and potentially leading to a recession that could have significant negative implications for Sterling in the medium term. The current narrative surrounding a potential rate hike by the BoE is providing support for GBP/USD via the yield channel. The potential for a medium-term recession in the UK, driven by stagflation, poses a significant threat. This contradiction illustrates why Cable’s technical patterns indicate bullish reversal setups, even as the fundamental backdrop remains fraught with uncertainty — the market is concurrently factoring in the hawkish BoE as a short-term catalyst while also considering the long-term economic repercussions.
