Financial markets enter a busy week with a tentative U.S.-Iran interim peace agreement reshaping investor expectations for inflation, oil and geopolitical risk. Policymakers around the world, including the U.S. Federal Reserve and the Bank of Japan, will deliver policy decisions that could be influenced by the deal. Market attention also falls on SpaceX in its first full week of trading following a record debut and on Anthropic, whose staff are meeting White House officials after a dispute forced advanced AI models offline.

Key Points

  • An interim U.S.-Iran memorandum of understanding is expected to be signed in Switzerland, with Pakistani officials saying the parties have agreed to an immediate and permanent end to military operations on all fronts; the agreement is not yet in force until signed.
  • The Federal Reserve's policy decision this week is central to markets, with expectations leaning toward a pause but uncertainty over future rate paths; global central banks including the BOJ, BoE, SNB, Riksbank and RBA will also announce decisions.
  • High-profile equity moves will be in focus: SpaceX enters its first full week of trading after a record debut that pushed valuation above $2 trillion, and Anthropic technical staff will meet White House officials about restricting access to advanced AI models.

Global markets open the week with a focus on a preliminary peace accord between the United States and Iran, an event that dominates investor discussion and has immediate implications for oil flows, risk premia and central bank policy expectations.

According to Pakistani officials, negotiators are preparing to sign a memorandum of understanding in Switzerland on Friday. Pakistani Prime Minister Shehbaz Sharif said the parties have "declared the immediate and permanent termination of military operations on all fronts," a statement that explicitly referenced Lebanon. Neither Washington nor Tehran has provided a detailed public account of the arrangement, and Tehran has signalled that the agreement will not take effect until it is formally signed.

Former President Donald Trump, commenting on the deal, said it would stop hostilities and allow the reopening of the Strait of Hormuz, a strategic waterway off Iran's southern coast through which about one-fifth of global oil flows moved before the conflict began in late February. Trump added that re-opening could occur on Friday, subject to mine-clearing operations, and that a longstanding American naval blockade of Iranian ports would also be lifted.


Markets' immediate reaction

In early trading, world equities showed gains and oil prices moved lower as investors recalibrated expectations for inflation and growth if the tentative ceasefire holds. Market participants and some strategists, however, urged caution about how quickly energy markets might return to their pre-crisis norms.

Analysts at ING noted that restarting infrastructure and logistics after sustained disruption will take time. They pointed to operational caution among some shipping operators reluctant to resume transits through the Strait of Hormuz in the near term, and to the need for inventories and strategic stockpiles to be rebuilt after recent dislocations. Those factors, ING said, should continue to support prices even as maritime flows gradually resume.


Federal Reserve decision in focus

A central focal point for investors this week is the Federal Reserve's policy decision on Wednesday and the accompanying Federal Open Market Committee statement. The peace agreement has heightened speculation about whether the Fed might alter the language of its guidance or the outlook for future rate moves, but expectations have consolidated around a pause in policy action this week, with potential rate increases re-entering consideration later in 2026.

Earlier optimism that the Fed would begin cutting rates this year has waned, particularly after recent data showed an acceleration in inflation. Analysts at Vital Knowledge argued that the committee is likely to remove an easing bias from its statement. They added, however, that new Fed Chair Kevin Warsh faces competing pressures between faster price growth and political calls for steeper rate cuts, and might try to nudge the post-decision interpretation toward a more dovish tone by reiterating that several Fed officials have said cuts would be appropriate if the Iran conflict ends.


Other central banks under the microscope

Beyond the Fed, a number of major central banks will deliver policy decisions this week. The Bank of Japan faces a significant test as it navigates energy-driven inflation, a weaker yen and growing political pressure. Market consensus is that the BOJ will raise rates to a level not seen in more than three decades in an effort to cool price pressures, a move that risks burdening an incipient economic recovery.

The Bank of England is widely expected to hold its policy rate at 3.75 percent on Thursday, maintaining a wait-and-see stance toward inflation that may contrast with the European Central Bank's recent decision to raise rates. Bank of England Governor Andrew Bailey has said that the BoE has "already tightened policy considerably" by abandoning plans for a possible rate cut in 2026. Other central banks announcing this week include the Swiss National Bank, Sweden's Riksbank and the Reserve Bank of Australia.


High-profile listings and market structure risks

In equity markets, the spotlight remains on SpaceX following a headline-making public debut. Shares of the aerospace and services group rose in premarket U.S. trading, extending gains from a record first day of trading that pushed the company's market value above $2 trillion and placed it among the most valuable publicly traded U.S. firms.

Elon Musk has projected that SpaceX, which now operates in satellite internet services and artificial intelligence chatbot businesses in addition to its core launch activities, could eventually reach $1 trillion in revenue by 2030. The company reported revenue of $18.7 billion in 2025. Retail investors were significant participants in the initial trading, buying about $117.6 million of SpaceX shares on the first trading day, according to data cited by a news agency from Vanda Research. Market commentators cautioned that the combination of a relatively small public float and a very high valuation could leave the stock vulnerable to volatility.


Anthropic-White House engagement

The market's appetite for large technology listings will be tested by other potential flotations, including that of AI developer Anthropic. Senior technical staff from Anthropic are scheduled to meet with White House officials this week in Washington to seek resolution of a dispute that has resulted in one of the company's most advanced models being taken offline.

The White House has ordered Anthropic to block access by foreign nationals, whether located inside or outside the United States, to its Mythos 5 and Fable 5 models. In response, Anthropic said it would disable those models globally. The company had previously indicated cybersecurity concerns about Mythos and released Fable with what it described as cybersecurity guardrails, yet still chose to remove the service while discussions continue.


What to watch this week

  • Diplomacy and implementation: Whether the memorandum of understanding is signed and the pace at which mine-clearing and operational steps allow the Strait of Hormuz to reopen as claimed.
  • Policy signals: The exact wording and any shifts in the Fed's statement, and how Fed officials, including the chair, frame the path of policy at the post-decision press conference.
  • Global central bank actions: The BOJ's decision on rates and language around the outlook for the yen and inflation, plus decisions from the BoE, SNB, Riksbank and RBA.
  • Market structure and listings: How SpaceX's shares behave beyond the debut and whether investor appetite extends to other large technology IPOs, amid concerns around float size and valuation.
  • AI governance and security: The outcome of Anthropic's talks with White House officials and the implications for access to advanced models that some parties view as posing cyber risks.

Investors and policymakers will be parsing each of these developments closely. The interplay between geopolitical outcomes and central bank decisions—particularly in the United States and Japan—could be decisive in shaping market momentum in the near term.

Risks

  • Oil prices may remain supported even if a ceasefire holds due to lingering operational caution, mine-clearing timelines and the need to rebuild inventories and strategic stockpiles, affecting the energy sector and inflation dynamics.
  • The Federal Reserve may remove an easing bias from its statement, leaving uncertainty about the timing of potential rate cuts and keeping interest-rate sensitive sectors like financials and real estate under scrutiny.
  • Newly listed, high-valuation stocks with limited free float, such as SpaceX, could experience heightened volatility, posing risks to equity market stability and to investors concentrated in these names; similarly, Anthropic's model restrictions could affect investor sentiment in AI-related technology stocks.
