Politics, Peace Talks and PCE: A Headline-Driven Week for Markets

The weekend has delivered two major developments that are likely to dominate market sentiment as trading begins: continued uncertainty surrounding the fragile U.S.–Iran peace framework, and a rapidly escalating political crisis in the UK. While economic data remains important this week, both of these stories have the potential to move currencies far more aggressively than any scheduled release, particularly if further headlines emerge over the coming days.

In the Middle East, what initially looked like a breakthrough week for diplomacy has quickly become far more complicated. Following the announcement of a tentative peace framework brokered by Pakistan and Qatar, markets had begun pricing in the prospect of a gradual normalisation of shipping through the Strait of Hormuz and a reduction in geopolitical risk. However, the weekend saw fresh tensions emerge. Reports suggest negotiations have continued behind closed doors in Switzerland, with U.S. representatives pushing for compliance mechanisms while Iran has simultaneously signalled plans to introduce maritime fees and restrictions on vessels using the Strait.

At the same time, President Trump has warned that military action remains an option if Iran fails to honour any future agreement. The result is a market that remains uncertain whether this is the beginning of a lasting settlement or simply another pause in a conflict that has already disrupted energy markets for months. While shipping traffic has continued to flow through the region, investors remain cautious, knowing that any deterioration could quickly push oil prices higher and reignite inflation concerns globally.

Meanwhile, much closer to home, UK politics has descended into what may become one of the most significant leadership crises in recent history. After weeks of pressure following Labour’s disastrous local election performance, reports over the weekend suggest Keir Starmer is now preparing to step down as Prime Minister. While no formal announcement has yet been made, speculation has intensified after reports that senior ministers delivered an ultimatum regarding his future, forcing a decision over the weekend.

Attention has already turned towards potential successors, with Andy Burnham emerging as the early favourite among many Labour MPs. If Starmer does resign, the UK would be heading towards its seventh Prime Minister in just ten years, a remarkable level of political turnover for a government that only secured a substantial parliamentary majority two years ago.

For Sterling, this creates a fresh layer of uncertainty at a time when markets are already trying to assess the impact of higher inflation, slower growth and changing central bank expectations. The combination of political instability in the UK and lingering uncertainty around the Strait of Hormuz means markets are likely to begin the week in a cautious mood, with both Sterling and energy markets particularly sensitive to incoming headlines.

With those major geopolitical and political developments setting the backdrop, investors will also be keeping a close eye on this week’s economic calendar, which contains several important releases capable of influencing the outlook for GBP, EUR and USD. While headlines may dominate in the short term, the data will still help shape expectations around inflation, growth and future central bank policy decisions as we move deeper into the second half of the year.

Monday: Lagarde Back in Focus

On Monday we have Eurozone Consumer Confidence data, followed by a speech from ECB President Christine Lagarde. Following the ECB’s recent rate hike and increasingly hawkish stance on inflation, markets will be listening closely for any hints regarding the next move.

With inflation now expected to remain elevated for longer than previously thought, many investors are already pricing in another ECB rate increase as early as July. Any comments that reinforce that view could provide further support for the Euro.

Tuesday: PMI Data Across the Major Economies

Tuesday brings flash PMI data from the Eurozone, UK and United States, covering both manufacturing and services sectors.

As these are preliminary estimates rather than final readings, markets do not typically react aggressively unless there is a significant deviation from expectations. That said, investors will still be looking for signs that higher interest rates and elevated energy costs are beginning to have a greater impact on business activity, particularly within the UK and Eurozone.

Wednesday: A Headline Day

Wednesday is relatively quiet from a scheduled data perspective, which means market attention may once again revert to headlines surrounding the U.S.–Iran negotiations and developments within UK politics.

Given the current environment, unexpected headlines may prove more influential than economic releases.

Thursday: The Main Event

Thursday is likely to be the busiest day of the week from a data perspective and is heavily focused on the United States.

We have Core PCE inflation, weekly jobless claims, durable goods orders, GDP data and real consumer spending all due for release during the afternoon session.

Particular attention will be paid to Core PCE, which remains the Federal Reserve’s preferred measure of inflation. Following the stronger-than-expected Non-Farm Payrolls report and recent shift in Fed rhetoric, any upside surprise in inflation could further strengthen the case for higher rates for longer and provide additional support for the Dollar.

Equally, GDP and consumer spending figures will offer valuable insight into the health of the U.S. economy, while jobless claims will continue to be watched closely for any signs of weakness beginning to emerge within the labour market.

Outlook

While the economic calendar is relatively light compared to recent weeks, there are still enough high-impact releases to generate volatility, particularly for Sterling and the U.S. Dollar.

However, it would be a mistake to view this as a purely data-driven week. The ongoing uncertainty surrounding the U.S.–Iran agreement and growing political instability in the UK have the potential to overshadow economic releases at any point.

For Sterling, the combination of domestic political uncertainty and a relatively light UK data calendar leaves the currency particularly vulnerable to headlines. For the Dollar, the focus remains on whether the recent strength in economic data continues and whether the Federal Reserve’s increasingly hawkish tone is justified.

As has been the case for much of this year, markets remain highly headline-driven. Economic data will matter, but political developments in Westminster and geopolitical developments in the Middle East may ultimately prove to be the biggest drivers of market direction over the coming days.

For anyone with upcoming currency requirements, this is another week where having a plan in place will be far more important than trying to react after markets have already moved.
