Political and monetary uncertainty

British Prime Minister Keir Starmer is going through a difficult period. The final straw was the resignation of Health Secretary Wes Streeting, who stated he had lost faith in the government's direction. This move has left Starmer in a very vulnerable position, especially after the poor results in the local elections from England, Scotland and Wales, which has encouraged sectors of the Labour Party to seek a replacement.

Analysts like Michael Pfister of Commerzbank suggest that the market is no longer asking if Starmer will leave, but when. There is a strong desire within his party to avoid the chaos that characterized the Conservatives, seeking an orderly exit. However, the risk lies in the fact that a potential successor, such as Manchester Mayor Andy Burnham, might not be well-received by bond investors, as he is perceived as having a profile less orthodox in tax matters>.

The major concern is that if the new leader decides to relax public spending and abandon the goal of a balanced budget, British government bonds could become unstable. Historically, when bonds suffer, the pound tends to follow the same downward trend, creating a vicious cycle of downward pressure on the currency.

The US dollar and the Federal Reserve factor

Foreign exchange markets

While the pound falters, the US dollar appears to be thriving. US economic data has proven surprisingly resilient, with solid retail sales and unemployment figures suggesting the economy remains strong. This has led investors to believe the Federal Reserve (Fed) will maintain its current policy stance. high interest rates for a longer period to combat inflation.

This divergence is stark: while the UK grapples with its internal problems, the US presents itself as a safe and profitable haven. The expectation of a restrictive monetary policy in the US has driven up demand for the greenback, which automatically weakens the GBP/USD pair's price, causing the pound to hit recent lows.

Furthermore, figures like Jeffrey Schmid and John Williams of the Fed have reinforced the idea that inflation remains the primary threat, ruling out immediate changes to interest rates. This stance leaves the pound in a very precarious position, as it currently lacks the support of a robust economy.

Geopolitical tensions and the conflict with Iran

Geopolitics and economics

It's not all about domestic politics. The international scene is also playing a crucial role. Uncertainty surrounding the reopening of the Strait of Hormuz and the tense negotiations between the United States and Iran have caused the pound to fluctuate wildly. The market reacts to every tweet or statement from Donald Trump, who has gone from optimism to frustration in a matter of hours.

When optimism about a peace agreement fades, investors once again seek refuge in the dollar, punishing the British currency once more. This volatility adds to the inflationary pressures caused by the energy shocks linked to the conflictThis has led economists at the Bank of England, such as Huw Pill, to suggest that it may be necessary to tighten monetary policy with further interest rate hikes.

Fiscal outlook and the role of the Bank of England

Bank of England and budget

The calendar marks a key date: the budget announcement on November 26. According to ING, the pound is currently trading at a risk premium that is likely to remain until then. Changes in direction regarding income tax have unsettled bondholders, adding fuel to the fire of the financial instability.

Within the Bank of England's Monetary Policy Committee, there is an internal struggle between the "hawks" (like Catherine Mann), who are concerned about rising food inflation, and the "doves" (like Swati Dhingra), who welcome the moderation in services inflation. This division makes the December interest rate decision a real balancing act.

Although first-quarter GDP was slightly better than expected, the latest UK hiring and retail sales data point to a cooling economy. If the final budget proves to be restrictive, it could open the door to a reduction of interest ratesThis, paradoxically, could alleviate the risk premium but further weaken the currency in the short term.

Monetary trends

The future of the pound sterling now depends on the political storm within the Labour Party subsiding and the conflict in the Middle East not escalating. As long as the shadow of unstable leadership looms over Downing Street and the dollar continues to demonstrate its strength, the British currency will continue to navigate turbulent waters, subject to budget volatility and central bank decisions.
