London's FTSE 100 index rose 1.66% on Thursday, joining a broader European rally that lifted stocks across the continent. The bounce came as investors looked ahead to Friday's final reading of the UK services purchasing managers' index (PMI), a key gauge of economic health in the country's dominant services sector.
What Is the Services PMI and Why Does It Matter?
The services PMI is a monthly survey of purchasing managers at services companies — businesses like banks, restaurants, and retailers. It asks about new orders, employment, and business confidence. A reading above 50 signals expansion; below 50 means contraction.
The June flash reading — an early estimate — fell to 48.7 from 49.3 in May. That was the lowest level since January 2023 and marked the second consecutive month below the 50 threshold. For context, the services sector accounts for roughly 80% of UK economic output, so a sustained contraction there can ripple through the broader economy.
Investors will scrutinize Friday's final number to see if the weakness holds or if the flash estimate was too pessimistic. A worse-than-expected final reading could raise concerns about a broader slowdown, while an upward revision might ease some fears.
What Drove Thursday's Rally?
Thursday's gains were broad-based, with most sectors in the green. A key contributor was AstraZeneca, which jumped after announcing a deal to develop small interfering RNA (siRNA) therapies in China. siRNA is a cutting-edge technology that can silence specific genes, offering potential treatments for diseases like cancer and rare genetic disorders. The deal underscores AstraZeneca's push into China's biotech market, a major growth area for the pharmaceutical giant.
Meanwhile, oil prices eased as diplomatic efforts between the US and Iran in Doha helped calm fears about disruptions in the Strait of Hormuz, a critical chokepoint for global oil shipments. Lower oil prices can benefit the FTSE 100, which includes many companies that consume energy, such as airlines and manufacturers.

What It Means for Investors
For everyday investors, the FTSE 100's rebound is a reminder that markets can recover quickly from short-term dips. But the bigger story is the services PMI. If Friday's final reading confirms contraction, it could increase pressure on the Bank of England to cut interest rates sooner than expected. Lower rates tend to boost stock valuations, especially for growth-oriented companies, but they also signal a weakening economy.
Investors should watch for any comments from Bank of England officials following the PMI release. A weak services sector might also weigh on the British pound, which could benefit exporters in the FTSE 100 but hurt the purchasing power of UK consumers.

Broader Market Context
The FTSE 100's rise on Thursday was part of a wider European rally, with Germany's DAX and France's CAC 40 also posting gains. This came after a period of uncertainty driven by geopolitical tensions and mixed economic data. The services PMI is just one piece of the puzzle, but it's a closely watched one because it provides timely insight into the UK's economic trajectory.
Investors are also keeping an eye on global factors, including oil prices and currency movements. The easing of Strait of Hormuz tensions has helped stabilize oil markets, but the situation remains fluid.

Looking Ahead
Friday's final UK services PMI will be the main event for UK-focused investors. A reading below 50 would confirm that the services sector is shrinking, which could lead to more cautious outlooks from companies and potentially slower hiring. On the other hand, an upward revision could signal that the economy is more resilient than the flash estimate suggested.
Either way, the data will help shape expectations for the Bank of England's next move on interest rates. For now, the FTSE 100's rebound shows that markets are willing to look past short-term weakness, but the sustainability of the rally depends on whether the economic data supports it.
