The British pound has shown an unexpectedly calm trajectory over a year of political and economic turbulence in the UK, surprising traders who had bet on its vulnerability to any market disturbance.

The pound was the second-best performer among G10 currencies last quarter, trailing only the Australian dollar, and ranks fourth in cumulative performance since 2026. Sterling has weathered not only the Middle East conflict, which upended interest rate expectations and threatened economic growth, but also a prolonged period of domestic political instability. This political volatility is expected to culminate with Andy Burnham becoming the UK's seventh prime minister in a decade.

"There has been a long-standing, strong bias to be short the pound," said Francesca Fornasari, head of currency solutions at Insight Investment, which manages around $80 billion in assets. "If you look at some of the long-term structural factors, I wouldn't say they are great, but they are much better than they were."

Analysts point to multiple factors behind the pound's relative strength. Despite the political turmoil, major political players have avoided proposing policies that could harm government finances. Sterling offers relatively high carry trade value compared to other low-yielding currencies, making short positions expensive. Furthermore, a significant influx of foreign investment into UK companies has further boosted demand for the pound.

"The M&A boom is unlikely to push sterling higher, but it may at least help cover the UK's structural current account deficit in the short term," said Kevin Thozet, a portfolio adviser at Carmignac.

Previously, investors had good reason to be skeptical of the pound. In 2022, former Prime Minister Liz Truss's proposal for significant tax cuts, without a clear funding plan, sent the pound crashing to a historic low below $1.04. Before that, years of Brexit negotiations also posed a major headwind for sterling, with analysts once comparing it to an emerging market currency.

In contrast, the pound's exchange rate now appears more stable. Over the past year, the euro has consistently traded above 0.86 against the pound, a key gauge of sterling's reaction to domestic political uncertainty. When the ruling Labour Party suffered a significant defeat in May's local elections, it was the UK bond market, not the pound, that felt the impact.

Mark Dowding, chief investment officer of fixed income at RBC BlueBay Asset Management, said he had been short the pound given the political turbulence but closed the position after Keir Starmer's resignation in June. "The market reaction was surprisingly calm, so we also realized that trade wasn't gaining momentum as we expected," he stated.

Looking ahead, politics remains a significant factor. Burnham, the frontrunner to succeed Starmer, initially caused some jitters in the bond market last year but later reassured investors by pledging to adhere to the borrowing and spending limits championed by Chancellor Rachel Reeves. The identity of Reeves's successor will be crucial.

"The market is holding its breath, but we haven't heard anything negative yet. In fact, most high-level statements show respect for fiscal discipline," said Themistoklis Fiotakis, a strategist at Barclays.

Investors are now hoping for greater policy clarity. Dominic Bunning, head of G10 FX strategy at Nomura, previously bet on a stronger euro against the pound but later closed the position, citing a "lack of catalysts and overall market stagnation." Bank of America took profits on an options trade last week as the euro fell against the pound. The bank views the key risk event as the Autumn Budget, where Reeves's successor will outline their policies.
