Sterling weakened against the US dollar in European trade on Wednesday, with GBP/USD down 0.38% to about 1.3150 after failing to hold its triangle breakdown zone. The pair stayed under pressure as the dollar outperformed on hawkish Federal Reserve expectations, and the US Dollar Index (DXY) rose 0.3% to around 101.70, its highest level in over a year.
Earlier in the session, GBP/USD was near 1.3195 but remained below 1.3200 as UK political uncertainty weighed on the pound following Keir Starmer’s resignation as Prime Minister on Monday. Markets are also positioned for the US May Personal Consumption Expenditures (PCE) Price Index, due later on Thursday, while the Labour Party faces a leadership transition after Andy Burnham’s win in the Makerfield by-election last week.
Impact of UK Political Instability and US Dollar Strength
With Keir Starmer’s resignation, we see immediate and significant pressure on the Pound, pushing it decisively below the 1.3200 level. The combination of UK political instability and a strong US Dollar creates a clear downward path for the currency pair. For now, the 1.3150 mark is the key battleground to watch for further weakness in the coming days.
This leadership vacuum in the UK introduces major policy uncertainty, which historically weighs heavily on Sterling. We only have to look back to the market chaos following the mini-budget of September 2022, when political turmoil sent GBP/USD spiraling towards parity. Consequently, we expect international investor confidence in UK assets to deteriorate until a new leader is confirmed.
On the other side of the trade, the US Dollar’s strength is underpinned by expectations of a hawkish Federal Reserve. Recent data shows US core inflation remains stubbornly above the Fed’s target at 2.8%, reinforcing the view that interest rate cuts are not imminent. This stark interest rate differential between the US and the UK will continue to attract capital towards the dollar.
Volatility, Trading Strategies, and Focus on US PCE Data
We are seeing a notable increase in expected price swings, with one-month implied volatility on GBP/USD options now trading above 9.0%, a significant jump from last week. This environment is becoming more favorable for strategies that can capitalize on sharp directional moves. Traders should anticipate this heightened volatility to persist throughout the leadership contest.
Given this bearish outlook, we are positioning through derivative markets to speculate on further declines. Buying GBP/USD put options with strikes around the 1.3000 level offers a defined-risk way to profit from the expected downward trend. Selling out-of-the-money call spreads is another viable strategy to generate income while maintaining a bearish bias.
All eyes are now on the US Personal Consumption Expenditures data due this Thursday. A higher-than-expected inflation reading would almost certainly accelerate the Pound’s fall, potentially breaking below the 1.3100 support level. We must be prepared for a significant market reaction following that critical data release.
