The fifth consecutive daily decline in sterling says it plainly: Markets appear to be repricing UK political risk, with gilt yields and sterling remaining under pressure . CNBC’s Joseph Wilkins reported that the FTSE 100 opened 0.7% lower on Friday morning, pulled down by an ongoing political uncertainty surrounding Prime Minister Keir Starmer, which some market participants associate with concerns around future fiscal policy direction.
The mechanism is straightforward: Manchester Mayor Andy Burnham now has a route to parliament after Labour MP Josh Simons announced his resignation from the Makerfield seat, clearing the path for a by-election. Burnham hasn’t declared yet, and a win is not guaranteed — Reform UK has real momentum in that kind of constituency — but the market doesn’t wait for declarations.
Some analysts and market participants have suggested that speculation around a potential leadership shift could raise questions about future fiscal policy direction and borrowing expectations . The pound fell 0.46% to $1.3342, its fifth straight losing session, according to CNBC.
Friday’s European Open by the Numbers
The UK selloff didn’t stand alone. Every major European index opened in the red, tracking an ugly Asian session:
| Index | Move at Open | Source |
|---|---|---|
| FTSE 100 | -0.7% | CNBC |
| DAX | -0.9% | CNBC |
| CAC 40 | -0.8% | CNBC |
| Stoxx 600 | -0.7% | CNBC |
| Kospi | -3%+ | CNBC |
| Nikkei 225 | -1.1% | CNBC |
South Korea led the damage. The Kospi fell more than 3%, retreating from a recent record high — a sharp reversal that shook confidence in the momentum that had been building across Asia-Pacific. Japan’s Nikkei shed 1.1%. Europe walked into that sentiment and compounded it with its own domestic headwinds.
Sterling’s Failure to Catch a Bid Is the Tell
The pound’s underperformance is the sharpest signal here. Sterling has remained under pressure across five consecutive sessions, even during periods of broader market stabilisation . Some analysts have compared the move to previous periods where markets focused closely on fiscal policy credibility and borrowing expectation . Burnham’s political positioning, described by CNBC’s report as leaning more to the left than Starmer, is enough for investors to get ahead of any actual policy announcement. The speculation alone has been sufficient to drive the move.
For FTSE 100 traders, the currency dimension cuts two ways. The index’s heavy weighting toward dollar-earning multinationals — miners, energy names, consumer staples with global revenues — tends to receive a mechanical translation boost when sterling weakens. That buffer may have limited the FTSE’s losses relative to the DAX’s 0.9% drop on Friday, even as domestically exposed mid-cap names likely bore a more direct hit. The Investing.com coverage of the session noted the Labour turmoil as a primary drag alongside external macro factors.
The US Inflation Print Adds a Second Front
The political story would be enough, but European markets are also absorbing a genuinely hostile US inflation backdrop. April’s producer price index came in at a sharply elevated annual gain — the largest since December 2022 — after a monthly increase that represented the biggest single-month jump since March 2022, per CNBC. That blew past the 0.5% consensus estimate and followed an upwardly revised 0.7% March reading. A day earlier, the consumer price index had come in at 3.8% year-on-year, with core at 2.8% — well above the Fed’s 2% target.
The combined print resets rate expectations. With core CPI running at 2.8% and PPI significantly elevated on an annual basis, markets have reduced expectations for near-term rate cuts. , particularly with energy prices elevated by the Iran conflict and tariffs still feeding through the supply chain. Markets in Frankfurt and Paris are repricing European rate trajectories partly in response — if the Fed stays on hold, the ECB’s room to move independently becomes more contested, and European growth proxies suffer.
The DAX’s 0.9% decline, the steepest of the major European indices on Friday, reflects that dynamic. German industry is exposed to global trade conditions and rate-sensitive capital goods demand in a way that French or UK blue chips are not to the same degree.
The Counter-Case: Reform UK and the By-Election Wildcard
The scenario the market is pricing carries a real hole in it. Burnham still has to win Makerfield, and Reform UK’s recent momentum in English by-elections means that’s far from certain. A A different political outcome could lead markets to reassess some of the recent risk premium reflected in sterling and gilt pricing . The market may be getting ahead of itself on the leadership trajectory, pricing a Burnham premiership before he’s even secured a parliamentary seat.
The US-China summit wrapping up Friday also represents a genuine upside catalyst that the macro community has arguably underweighted in today’s sell-off. Both sides agreed this week on keeping the Strait of Hormuz open, per CNBC. Any progress on tariffs or a broader trade framework coming out of Beijing could move risk appetite sharply, giving Europe a reason to recover off the lows into the close.
What’s Ahead
The immediate calendar centres on whether Burnham formally declares his candidacy for the Makerfield seat and any further developments from the Beijing summit. On the macro side, markets remain focused on the Federal Reserve’s response to the now-entrenched inflation overshoot — the FOMC calendar and any Fed communications in the days ahead will determine whether the dollar’s rate support stays intact, which in turn keeps pressure on sterling. UK political developments are now the primary near-term driver of the FTSE’s direction and should be tracked via the Bank of England’s communications for any sovereign-risk spillover into gilt markets.
