GBP/USD Slides as Dollar Strengthens

As of March 12, 2026, GBP/USD is positioned at 1.3380, marking a continuation of losses for the third straight session. This follows a rally from Monday’s lows that encountered the 100-day Simple Moving Average at 1.3437, where it faced a decisive rejection. The recent rejection is not merely a coincidence or background noise; it serves as a technical market confirmation of the macro signals that have been evident since the onset of the Iran war on February 28. The U.S. dollar is experiencing a structural safe-haven demand that the British pound lacks the domestic fundamentals to counteract. The pair reached support at 1.3360 during early European trading, showing a slight recovery. However, the nine-day Exponential Moving Average is on a downward trend, the 50-day EMA remains flat and is currently serving as overhead resistance, while the 100-day SMA at 1.3437 has successfully rejected three distinct attempts to advance. The 200-day SMA is positioned significantly higher at 1.3554, and the observation that the 100-day is trading below the 200-day on the 4-hour chart exemplifies a medium-term downtrend that remains intact. The RSI at 51.20 presents a moderately constructive signal, positioned just above neutral and technically aligning with a momentum shift toward bullish sentiment. However, an RSI of 51 in a dollar-dominated landscape influenced by geopolitical risk and inflation repricing serves as a data point rather than a comprehensive thesis. The overall framework indicates a negative outlook.

The U.S. Dollar Index is currently positioned around 99.70 as of March 12, maintaining levels not observed since November 2025. The resistance level at 99.57 was maintained for a session before facing another test, indicating a clear upward directional pressure. The strength of the dollar cannot be attributed to a single factor; rather, it is the result of a complex interplay involving safe-haven demand, inflation adjustments, and the collapse of rate cut expectations, which is systematically affecting every dollar cross within the G10 space. Two weeks prior to the onset of the Iran war, markets were anticipating around 66 basis points of Federal Reserve reductions through 2026. As of March 12, that figure has been reduced to around 30 basis points — a 54% decrease in expected easing over a span of 13 days. The trajectory of that repricing has been consistently one-directional: each new escalation in the Strait of Hormuz, every additional tanker attack, and every statement from Iran’s new Supreme Leader Mojtaba Khamenei regarding the permanent closure of the strait as a “tool to pressure the enemy” — all of these events diminish the likelihood that the Fed can implement rate cuts this year without reigniting the inflation that $97-to-$100 Brent crude is already poised to entrench. Goldman Sachs has adjusted its forecast for the first Federal Reserve rate cut to September at the earliest, shifting away from the previous consensus of spring or early summer just weeks prior. The bank’s model indicates that with an average Brent price of $98 in March and April, the Fed’s favored PCE inflation metric is expected to conclude 2026 at 2.9%. With an average Brent price of $110, PCE reaches 3.3% — a threshold where reducing rates becomes politically and analytically untenable for any Fed governor committed to an effective inflation mandate. Current rate derivatives indicate that markets are not fully pricing in even a single 25-basis-point cut in 2026. This represents a significant change in the interest rate differential that forms the foundation of all GBP/USD valuation models, and it is occurring in real time. A dollar that must account for 66 basis points of cuts and substitute them with near-zero easing is inherently supported, while Cable remains under structural pressure as long as that repricing persists.

The technical framework beneath the current price levels is clearly outlined and provides the bearish scenario with specific price targets. The first support that has been holding intraday is the 1.3360 handle, where buyers have been stepping in during European morning sessions. Below that, 1.3379 serves as a near-term consolidation floor that, if breached on a closing basis, paves the way to the recent low of 1.3333. A decisive drop below 1.3333 marks a significant technical development that propels the downward movement — at this juncture, the target sequence shifts to 1.3250 and subsequently to levels not observed since the lows of August 2025, positioned around the 1.3150 area. The pair must maintain a position above 1.3450 — not merely reach it during the day but also finish above it — to negate the existing bearish framework. At 1.3450, the configuration transitions to a neutral stance, making a test of the 200-day SMA at 1.3554 a plausible scenario. That represents roughly 170 pips of movement from current levels, in contrast to a bearish outlook that could extend 230 pips downward from 1.3380 to 1.3150. The potential benefits of taking a short position outweigh the associated risks. Consider selling GBP/USD if there is any recovery towards the range of 1.3420-1.3437. Cease trading above 1.3460. Targets: 1.3333, followed by 1.3250, and subsequently 1.3150 should macro deterioration intensify. The process by which the Iran conflict is undermining the upward potential of GBP/USD is clear and measurable. Brent crude surged 8% to $99.35 on March 12. WTI added 8.2% to reach $94.52. At the current energy price levels, every central bank in developed markets is confronted with a similar challenge: the economy is decelerating as a result of the demand-destruction effect from the oil shock, while inflation is on the rise due to the supply-side pass-through impacts on transportation, food, utilities, and industrial inputs. For the Federal Reserve, this indicates that the September cut projected by Goldman is considered the base case — rather than the minimum threshold. Market sensitivity to optimistic military updates from the Trump administration has noticeably diminished over the past week, as the IEA’s 400-million-barrel emergency release did not succeed in driving oil prices lower.

Investors are coming to terms with the reality that strategic reserves cannot substitute for the 20 million barrels per day that typically pass through the now-closed Strait of Hormuz. The White House is evaluating a Jones Act waiver, permitting foreign-flagged vessels to transport energy products among U.S. ports. This domestic logistics strategy does not address global supply issues and indicates that the administration perceives this disruption as significant rather than temporary. Markets are currently pricing in a potential 3% increase in U.S. headline inflation for the upcoming month. The UK headline inflation rate continues to exceed the Bank of England’s target of 2%, with the energy price shock contributing a direct imported inflation aspect that remains beyond the control of the BoE’s domestic policy measures. In contrast to the U.S., which benefits from substantial domestic oil production that mitigates the impact of import prices, the UK operates as a net energy importer, facing considerable vulnerability to fluctuations in global crude prices. Brent priced between $97 and $100 presents a clearly adverse macroeconomic factor for the UK economy. It elevates household energy expenses, escalates transportation costs throughout the supply chain, squeezes corporate margins in sectors reliant on energy, and diminishes real disposable income during a period when consumer confidence is already precarious. The Bank of Canada’s anticipated rate stability until 2026 illustrates the ongoing tension between inflation and growth. However, Canada’s position as a commodity exporter provides a degree of insulation from the oil price shock, a benefit that the UK does not share. USD/CAD at 1.3621 and the Canadian Dollar’s Structural Contradiction — Oil Up 8%, CAD Still Losing to the Dollar USD/CAD at 1.3621 on March 12 — recovering from one-month lows near 1.3525 earlier in the week — highlights the extent to which demand for the dollar as a safe haven is overshadowing the typical dynamics associated with commodity-linked currencies.

Canada stands as the largest external oil supplier to the United States. The recent 8% surge in Brent within a single session is expected to provide a notable advantage for the CAD, given that Canadian producers gain directly from higher crude prices, leading to an improvement in the trade balance. However, the prevailing dominance of the dollar in the current environment is overshadowing that transmission. The underlying factor is structural: oil is denominated in U.S. dollars, which necessitates that global energy purchasers acquire USD to buy crude — thereby elevating dollar demand in an environment where oil prices are concurrently increasing. During a geopolitical crisis, the influx of safe-haven flows into the dollar intensifies that dynamic. The outcome indicates that even a significant upward movement in oil commodities does not counterbalance the overall demand for the dollar. The movement of USD/CAD from 1.3525 to 1.3621, coinciding with an 8% increase in oil prices, serves as a striking illustration of the dollar’s strong influence on the current foreign exchange landscape among G10 currencies. Tomorrow’s Canadian labor market data presents potential headline risk for USD/CAD. However, unless there is a truly unexpected employment figure — and considering the current macroeconomic environment — the most likely trajectory for USD/CAD appears to be upward, targeting 1.3700 and possibly reaching 1.3800 if the Iran conflict persists beyond the end of March without a resolution. The Bank of Canada’s anticipated pause until 2026 removes any potential interest rate differential support for CAD that could have otherwise established a baseline.
