The past several weeks have been marked by significant volatility across global financial markets, driven primarily by the ongoing conflict between the US and Iran, fluctuating oil prices, and a strong corporate earnings season. Major US stock indices have repeatedly reached new record highs, while other markets, including Australia's, have experienced sharp swings. Key developments include the closure of the Strait of Hormuz, multi-billion dollar corporate writedowns, and leadership changes at major companies.
Market Performance: Mixed Results Across Global Indices
United States
The S&P 500, Dow Jones Industrial Average, and Nasdaq composite have frequently hit new all-time highs. For instance, the S&P 500 rose 0.3% to 7,041.28 in one session, later climbing to 7,230.12. In another session, it reached 7,519.12.
The Dow Jones Industrial Average closed above 50,000 for the first time since the war began in one instance, showing remarkable strength.
Australia
The S&P/ASX 200 index has experienced significant fluctuations. It has seen daily declines of over 1% and rises of over 2%, often in reaction to the latest news from the Middle East. The Australian dollar has traded in a range, typically between US68.49¢ and US71.99¢.
Geopolitical Conflict and Oil Markets
The central geopolitical factor has been the conflict between the US and Iran, which has severely impacted the Strait of Hormuz, a critical waterway for global oil shipments.
- Strait of Hormuz: The strait has been largely closed due to the conflict. The US and Iran have exchanged fire on vessels, with the US enforcing a blockade and Iran firing on ships attempting to transit.
- Oil Price Volatility: Brent crude oil prices have surged from a pre-war level of under $70 per barrel to a war-time peak of $119.50 per barrel. Prices have since fluctuated dramatically, settling in a range between the mid-$80s and $108 per barrel depending on the day's news.
The International Energy Agency has called the situation "the largest energy security threat in history."
- Diplomatic Efforts: Multiple attempts for a ceasefire and peace talks have been made, with the US and Iran holding negotiations mediated by Pakistan and other parties.
US President Donald Trump has made a series of public statements, describing talks as "very good and productive" while also threatening further military action, including strikes on Iranian infrastructure. These pronouncements have been a primary driver of daily market swings. Iran has offered to reopen the strait if the US ends its blockade, but also stated it would skip ceasefire talks while the blockade remains. News of a tentative agreement to extend a ceasefire by 60 days, conditional on reopening the strait, has periodically eased oil prices and boosted markets.

Economic Indicators and Policy
Central Bank Policy
The US Federal Reserve has held interest rates steady at its most recent meetings, but has signaled possible cuts in the coming months. Some Fed officials disagreed with this stance. The Reserve Bank of Australia has raised interest rates twice this year due to inflation risks from the conflict.
Inflation and Growth
The conflict has contributed to higher inflation and slower economic growth concerns globally. A Woolworths executive warned that higher fuel costs would have an increasing inflationary impact. China reported 5% economic growth for the January-March quarter, but economists warned its export sector faces challenges due to slower global growth.
Bond Markets
US Treasury yields have risen significantly since the war began, with the 10-year note rising from below 4% to almost 4.65% at one point, before settling back.
Consumer Confidence & Employment
