GBP/USD rises as US Supreme Court blocks Trump tariffs

• GBP/USD climbs after the Supreme Court of the United States curbs tariffs backed by Donald Trump.
• US GDP slows sharply, while core PCE jumps to 3%, signaling stagflation risks.
• Diverging rate expectations between the Federal Reserve and Bank of England cloud near-term outlook.

The GBP/USD edges higher over 0.23% after the US Supreme Court ruled against President Donald Trump’s tariffs enacted under a a law meant for use in national emergencies. This and a softer than expected Gross Domestic Product report in the US weighed on the Dollar. The pair trades at 1.3494 at the time of writing.

Sterling gains after US court ruling dents the Dollar, while softer GDP offsets hotter core PCE

US economic data on Friday revealed a stagflationary picture as GDP in Q4 2025, decelerating from 4.4% to 1.4% YoY, sponsored by the disruptions of the 43-day government shutdown. At the same time, the US Core Personal Consumption Expenditures (PCE) Price Index, the Fed’s favorite inflation gauge, jumped to 3% in December, exceeding estimates of 2.9% and the prior’s print of 2.8%.

Following the data release, US equity markets edged lower, but recovered on news that the US Supreme Court declared tariffs illegal under the IEEPA without the approval of the US Congress. The US Treasury Secretary Scott Bessent and other White House officials commented that the US would invoke other legal justifications to maintain as many of Trump’s duties as possible.

Following the SCOUT ruling, the Greenback edges lower as depicted by the US Dollar Index (DXY). The DXY, which measures the buck’s performance versus six major currencies, is down 0.14% at 97.67.

Across the pond, UK Retail Sales exceeded estimates of 2.8%, rose by 4.5% in January according to the Office for National Statistics (ONS). Business activity is also gathering pace as the S&P Flash PMIs in February, expanded in both services and manufacturing.

Nevertheless, weaker than expected employment figures, warrant further easing by the Bank of England, as the unemployment rate picked up in Q4 2025.

Money markets had priced in an 80% chance of a rate cut by the BoE in March. Meanwhile, traders pushed back the Federal Reserve’s first rate cut to June. Hence, the divergence of monetary policies between the US and UK central banks could pave the way for a pullback in the GBP/USD before the ongoing uptrend resumes.

GBP/USD Price Forecast: Technical outlook

In the daily chart, GBP/USD trades at 1.3498. The Moving Average Triple slopes higher, maintaining a supportive backdrop. Price holds beneath the latest simple average near 1.3530, which caps immediate upside. The FXS Fed Sentiment Index has eased to 114.93, tempering follow-through momentum.

The rising trend line from 1.3035 underpins the bullish setup, with support tracked around 1.3528. A decisive close above that level would reinforce the advance, whereas failure to reclaim it would leave the pair confined to consolidation. With trend support nearby, a break would shift risk lower and expose a corrective phase.
