Introduction:

The United States significantly escalated the Israel-Iran conflict with military strikes on three major Iranian nuclear sites on Saturday, June 21, marking its first direct involvement in the war. This action, justified by the U.S. as an effort to prevent Iran from acquiring nuclear weapons, immediately sent shockwaves through global markets, causing oil prices to surge to five-month highs and the U.S. dollar to firm as investors sought safety amidst increased volatility. The international community’s reactions have been notably diverse, reflecting the profound geopolitical implications of these events.

Key takeaways from sources:

Significant Escalation and U.S. Direct Involvement: The United States conducted military strikes on three major Iranian nuclear sites (Fordow, Natanz, and Isfahan) on Saturday, June 21. This operation marks the United States’ first direct involvement in the Israel-Iran war and a significant escalation of the conflict, carried out partly at Israel’s behest. U.S. President Donald Trump declared the facilities “completely and totally obliterated”. Iran has vowed retaliation, stating its armed forces will decide the “timing, nature and scale of Iran’s proportionate response”.
Immediate Market Volatility and “Wait-and-See” Sentiment: Global markets reacted with immediate volatility, most notably with oil prices hitting a five-month high. The U.S. dollar firmed slightly as a safe-haven asset, while global stocks generally slipped. However, overall market moves were initially “muted” or in a “wait-and-see mode,” suggesting investors were treating the strikes as a “contained event” rather than the start of a broader war, awaiting Iran’s response. Cryptocurrencies like Bitcoin and Ether also saw initial drops before slight recoveries.
Critical Role of the Strait of Hormuz and Oil Price Concerns: A major concern is Iran’s parliament approving a move to close the Strait of Hormuz, a narrow waterway through which nearly a quarter (or 20-26%) of global oil shipments and 20% of liquefied natural gas supplies pass. Analysts warn that any closure or significant disruption to this Strait would send oil prices sharply higher, with forecasts ranging from Brent crude reaching at least $100 per barrel to potentially spiking towards $130 per barrel.
Inflationary Pressures and Central Bank Policy Implications: A sharp rise in oil prices would “filter through to global inflation,” which is already elevated in many regions. This inflationary impact is expected to force central banks, including the Federal Reserve, to delay or even “reconsider the easing cycle altogether,” potentially halting planned interest rate cuts that markets had been pricing in for the second half of the year. Federal Reserve Chair Jerome Powell is expected to address these inflationary risks during his Congressional testimony.
Diverse International Reactions:
- Condemnation: Tehran’s key allies, Russia and China, along with Pakistan, strongly condemned the U.S. military action, proposing a UN Security Council resolution for an “immediate and unconditional ceasefire”. The UN Secretary-General António Guterres expressed being “gravely alarmed” by the U.S. use of force and called for a peaceful solution and diplomacy. Carl Bildt of the European Council on Foreign Relations called it a “clear-cut violation of international law”.
- Support: The United States and Israel strongly defended their military action at the UN Security Council, stating Iran cannot be allowed to have a nuclear weapon. UK Prime Minister Keir Starmer offered firm endorsement of the bombing.
- Cautious/Nuanced: South Africa’s President Cyril Ramaphosa issued a “mild reprimand,” expressing “anxiety” and urging dialogue, reflecting a “diplomatic egg dance” due to warm relations with Iran (a BRICS member), strong criticism of Israel, and the need to avoid alienating the Trump administration. Saudi Arabia, a new BRICS member, expressed “great concern” over the targeting of Iranian nuclear facilities.
Uncertain U.S. Economic Outlook: The conflict introduces “fresh uncertainty into the outlook for inflation and economic activity” in the U.S.. A rise in oil prices could put “powerful downward pressure on households’ ability to spend” and further slow U.S. GDP, which was already expected to slow due to tariffs. The labor market is showing signs of losing momentum, and consumer spending growth is projected to be weak.
Shifting Investment Landscape: The U.S. strike is seen as a “market-defining moment” that has “fundamentally shifted the global outlook” and broken the framework of lower inflation, falling rates, and stable energy prices. This could lead to “broad-based repricing across the global economy”. Investors are expected to shift out of rate-sensitive and consumer-driven sectors, with travel, tourism, and some tech stocks potentially coming under pressure, while safe-haven flows are expected to intensify, leading to further rallies in gold.
