The fragile ceasefire between the United States and Iran has once again come under significant strain, with another weekend of military escalation reminding markets just how quickly geopolitical risk can return.
What had appeared to be a tentative step towards stability following the June 17 peace framework has instead evolved into renewed confrontation, with both Washington and Tehran accusing each other of violating the agreement. As a result, investors head into the new week once again balancing hopes of diplomacy against the risk of a wider regional conflict.
The latest escalation centred around the Strait of Hormuz, one of the world’s most strategically important shipping lanes and the route through which around 20% of global oil supplies pass. Tensions flared after a series of attacks on commercial shipping over the weekend, including a drone strike on the Panama-flagged tanker Kiku, which was carrying more than two million barrels of Qatari crude oil. The vessel had reportedly been using an alternative Western-backed shipping corridor near Oman rather than Iran’s preferred transit route, prompting Tehran to warn that any ships operating outside its designated channels could be considered hostile. The incident highlights that, despite the ceasefire, one of the fundamental disagreements between both sides, namely who ultimately controls access through the Strait of Hormuz, remains far from resolved.
Washington responded swiftly. President Trump authorised two waves of airstrikes targeting Iranian military infrastructure linked to operations around the Strait, including coastal radar installations, drone storage facilities, air defence systems and naval assets believed to support future attacks on commercial shipping. Iran retaliated just hours later, launching missile and drone attacks against several U.S.-aligned military facilities across the Gulf, including bases in Bahrain and Kuwait. Although regional air defence systems successfully intercepted most of the incoming attacks and no major casualties have been reported, the exchange marks the most significant deterioration in relations since the ceasefire was announced.
For financial markets, this keeps geopolitical risk firmly at the forefront. Diplomatic talks taking place in Switzerland now appear increasingly fragile, with both sides hardening their rhetoric while global shipping authorities have once again raised the security threat level in the Strait of Hormuz. Oil prices remain highly sensitive to developments in the region, and any further disruption to shipping could quickly feed through into higher energy costs, inflation expectations and increased volatility across currency, commodity and equity markets. While investors continue to hope diplomacy ultimately prevails, the events of the weekend serve as another reminder that markets remain just one headline away from another sharp move.
Against that backdrop, we also enter the final trading days of June and the beginning of July. Quarter-end and month-end flows often bring an additional layer of volatility as institutional investors rebalance portfolios, close positions and prepare for the start of a new quarter. Combined with a busy economic calendar and the ongoing geopolitical backdrop, this could make for another lively week across FX markets.
Monday
The week begins with UK mortgage approvals and consumer credit data. Mortgage approvals are expected to soften slightly from the previous month, although activity may remain relatively resilient as buyers and sellers continue trying to complete transactions ahead of any potential change in government and the possibility of future tax reforms.
Later in the day we have Eurozone Consumer Confidence, which is expected to remain firmly in negative territory, highlighting that households across the bloc remain cautious despite signs that inflation is gradually becoming more manageable.
Tuesday
Tuesday’s main UK release is quarterly GDP growth, where economists expect growth to improve to 0.6%. A stronger reading would reinforce the recent narrative that the UK economy has remained more resilient than many expected and could offer some support to Sterling, particularly if accompanied by improving business sentiment.
Wednesday
Wednesday marks the beginning of July and brings Manufacturing PMI data from the Eurozone, the UK and the United States. As always, the key level to watch is 50, with anything below indicating contraction within the manufacturing sector.
We also receive Eurozone flash inflation figures, expected to remain unchanged at 2.6%. Stability here is unlikely to move the Euro significantly unless the data surprises meaningfully in either direction.
Later in the day, U.S. ADP employment figures are expected to soften compared with the previous month, offering markets an early indication of labour market conditions ahead of Thursday’s Non-Farm Payrolls report.
Markets will also be paying close attention to speeches from Bank of England Governor Andrew Bailey, ECB President Christine Lagarde and incoming Federal Reserve Chair Kevin Warsh. Given the recent shift in central bank rhetoric towards keeping policy tighter for longer, any fresh guidance on inflation or interest rates could generate volatility.
Thursday
Thursday is undoubtedly the biggest day of the week.
Eurozone unemployment data is released first before attention turns firmly to the United States, where weekly jobless claims, average earnings and the all-important Non-Farm Payrolls report will be published a day earlier than usual due to Friday’s Independence Day holiday.
After last month’s stronger-than-expected payrolls report, markets will once again be looking for confirmation that the U.S. labour market remains resilient. Another strong employment reading would reinforce expectations that the Federal Reserve will keep interest rates higher for longer, providing further support for the Dollar. Conversely, any meaningful downside surprise could quickly reverse some of the Dollar’s recent gains.
Expect volatility across all major currency pairs throughout Thursday afternoon.
Outlook
This week has all the ingredients for another volatile period in financial markets.
Geopolitical tensions remain elevated following the latest deterioration in U.S.–Iran relations, while quarter-end flows and the start of a new month are likely to amplify market moves. Added to that, we have key UK growth data, central bank speeches and one of the most closely watched U.S. employment reports of the month.
For Sterling, Tuesday’s GDP figures could determine whether recent resilience continues. For the Dollar, Thursday’s labour market data remains the key event, while broader market sentiment will continue to be influenced by developments in the Middle East.
As has become the theme throughout much of this year, economic data tells only part of the story. Political developments, geopolitical headlines and central bank communication continue to move markets just as quickly, making preparation and timing more important than ever for anyone with upcoming currency requirements.
