The panel agrees that the US-Iran 60-day truce renewal has bullish implications for equities due to lower oil prices, but they caution about potential risks such as demand contraction, geopolitical flare-ups, and the temporary nature of the deal. The panel is divided on the impact on rates, with some expecting cuts due to lower inflation and others seeing a cautious Fed stance due to sticky inflation dynamics.
Risk: Demand contraction leading to a recession, which could pressure earnings growth and equity multiples despite lower rates.
Opportunity: Potential localized fiscal stimulus in the Middle East if the US-Iran deal includes unfreezing of assets, leading to a liquidity injection and a 'melt-up' in the S&P 500.

Stock markets in Europe have opened higher this morning, amid cautious optimism that the US and Iran are on the verge of securing a 60-day truce renewal.
The UK’s blue chip FTSE 100 index has opened up about 0.1% higher this morning. The Stoxx Europe 600 is up 0.3%.
Mohit Kumar, of the broker Jefferies, explains that a US-Iran deal could have a greater impact on investors’ expectations for interest rate movements this year than in the stock market.
In terms of market reactions if a deal is agreed upon, we should see another leg higher in risky assets and lower in rates. However, positioning suggest that the rates market should see a greater reaction than equities.
For equities, we are still bullish, but believe that the easy part of the rally is behind us. S&P positioning has reached just above 5, while Eurostoxx is at +2.2. Positioning is not extended yet, but beyond the relief reaction of a deal, we do not see a massive move higher from these levels. European equities can get a boost higher in the near term simply because positioning is much less crowded than in the US.
For rates, positioning is on the short side, with [US Treasuries] positioning just below -4 and Bunds close to -3. The recent rally in rates has led to some short covering in both US and Europe, but we still see more room to go. Our view remains that the front end of Europe, UK and the US are still mispriced. For the ECB, we can see one hike (in June), simply because they have to justify their inflation credibility. However, we do not see a series of rates hikes and maintain our long position at the front end of the curve.
For Fed and the BoE, we maintain the view that the next move would be a cut and not a hike. Markets have repriced in the UK with only 35bp of hikes priced for this year and less than 2 hikes till terminal. Our view remains that the BoE would be taking rates towards 3% by middle of next year and keep our long position at the front end of the curve.
For the Fed, we do not see a Warsh Fed delivering any hikes. For us, the question is when and not if there will be a cut. From a fundamental perspective, we would argue that near term inflation would be high and hence will be difficult for Warsh to deliver a rate cut before mid-terms. But there is a political element, and eventually it would depend on how soon oil prices drop below $80 and central banks start treating the latest oil price shock as a transitory effect on inflation rather than leading to second round effects. Our base case remains one of 2 rate cuts over the next 12 months.
Oil on track for one of its biggest monthly drops ever
Brent crude, the international benchmark for oil, is heading towards one of its biggest monthly drops ever as it nears a fall of 17% since the start of May.
The market is hopeful that a US-Iran deal, which would extend the ceasefire by 60 days and reopen the strait of Hormuz, will materialise.
Jim Reid of Deutsche Bank notes that the details will be important, but that “US Treasury Secretary Bessent said that Trump’s three ‘red lines’ for a deal are for Iran to open the Strait of Hormuz, turn over its enriched uranium and end its nuclear program. And Bessent also posted earlier in the day that the US would ‘not tolerate any effort to impose a tolling system in the Strait of Hormuz.’”
Whilst the geopolitical headlines provided the main boost to markets yesterday, they got further support after the latest US PCE inflation print was softer than expected, easing concern around the need for rate hikes. The release showed that headline PCE was only up +0.4% in April (vs. +0.5% expected), whilst core PCE was up +0.2% (vs. +0.3% expected). So that led investors to dial back expectations for a Fed rate hike, with the probability of a hike by December down to 59% by the close, having been at 62% the previous day.
Fed officials also didn’t sound in a rush to hike either, with NY Fed President Williams saying that monetary policy “is right where we want it to be”. Admittedly, there was discussion of a hike, with St Louis Fed President Musalem acknowledging there “there is a scenario where the economy might require a rate increase”, but that was still conditional.
The draft is similar to the one that has been circulating around the Middle East, under which the strait of Hormuz would be opened to commercial shipping, the US blockade of Iranian ports would be lifted and Iran would be given access to as much as $12bn (£9bn) in frozen assets.
The aim would be for commercial shipping in the strait to return to pre-war levels within 30 days. Negotiations are expected to last as long as 60 days on the future of Iran’s nuclear programme.
Stocks are rising strongly in Asia, with the Japanese Nikkei up 2.65%, Hong Kong’s Hang Seng up 0.9% and the South Korean Kospi up 3.6%.
Some of the rally in Asia is being supported by enthusiasm for AI – shares in the chip making giant TSMC are up 2.6%, while Samsung Electronics and SK Hynix are up 6% and 0.6%, respectively.
The oil price has also slipped this morning. Brent crude, the international benchmark, is down by about 1% to $93.02 a barrel as investors weigh the impact of the potential reopening of the strait of Hormuz.

Four leading AI models discuss this article
"Any equity relief rally from the truce will be capped because positioning is already stretched and the nuclear concessions required make a durable deal unlikely within 60 days."
The article frames a US-Iran 60-day truce renewal as a clear positive for equities and rates via lower oil and softer PCE, yet glosses over execution risks and the temporary nature of any deal. Jefferies data already shows S&P positioning above 5 with limited further upside, while European equities gain only from relative under-positioning. Brent at $93 still leaves room for second-round inflation effects if the strait reopens slowly or nuclear talks stall. Front-end rate cuts priced for Fed and BoE rest on oil falling below $80 quickly, an assumption the article treats as probable rather than conditional.
Even if the deal collapses, the article's own PCE print and Williams comments already show markets dialing back December hike odds to 59%, limiting any sharp reversal.
"The market is pricing a successful Iran deal *and* sustained low oil *and* Fed cuts, but only one of those three needs to fail for this rally to reverse sharply."
The article conflates two separate bullish narratives—Iran deal + soft PCE—into one momentum story, but they point in opposite directions on rates. A US-Iran deal should push oil lower and rates higher (inflation relief), yet Kumar explicitly argues rates will fall more than equities rise. That's only true if the deal *fails* or disappoints, triggering risk-off. The 17% monthly oil drop is already priced in; Brent at $93 isn't crisis-level. The real tension: if the deal holds and Hormuz reopens, oil stays subdued, inflation stays benign, and the Fed cuts sooner—bullish equities long-term but bearish near-term if positioning unwinds. The article treats this as unambiguously positive; it's actually a Goldilocks scenario that's fragile.
Iran deal talks have collapsed before; a 60-day truce is a ceasefire, not a resolution. If negotiations stall in week 4, oil spikes back above $100, inflation re-accelerates, and the Fed's 'cuts by mid-year' thesis evaporates—leaving equities at 5200+ on the S&P with no rate support.
"The current equity rally is a fragile reaction to geopolitical headline risk that ignores the recessionary implications of a rapid decline in oil prices."
The market is prematurely pricing in a geopolitical 'all-clear' signal. While a 60-day truce and the reopening of the Strait of Hormuz would alleviate immediate supply-side inflationary pressure, the structural issues—specifically the $12bn in frozen assets and the unresolved nuclear status—remain massive tail risks. Equity markets are currently trading on 'relief' rather than 'fundamentals,' ignoring that if oil drops below $80, it likely reflects a sharp contraction in global demand rather than a diplomatic triumph. I am skeptical of the 'soft landing' narrative; if the Fed or BoE pivots to cuts, it may be because they see a recessionary cliff, not because inflation has been tamed. Stick to defensive quality in the Eurostoxx 600.
A successful reopening of the Strait of Hormuz could trigger a massive supply-side disinflationary shock, providing the 'immaculate disinflation' environment that allows central banks to cut rates while growth remains resilient.
"Durable de-escalation in the Middle East and a credible inflation decline are prerequisites for a durable rally; near-term moves may look constructive, but durability is uncertain."
Even with a US-Iran pause, the macro setup remains delicate. The 60-day truce narrative could be short-lived if sanctions relief or Hormuz reopening details don’t hold, leaving markets vulnerable to a swift reversal. The article’s tilt to imminent Fed cuts hinges on inflation fading; but PCE shows stickier dynamics that could push the Fed toward a cautious stance, delaying the expected easing path and weighing on risk assets later. A sharp, durable oil-price rebound or a geopolitical flare-up could derail optimism. Asia tech gains look supportive, but they’re a fragile offset to potential macroheadwinds and policy risks elsewhere.
The deal’s durability is highly uncertain; even a temporary easing could fail to translate into lasting relief if inflation proves stickier than hoped or if tensions re-escalate, risking a quick afterglow fade.
"Oil falling from demand weakness would hurt equities more than any rate relief helps."
Claude's rate-equity divergence claim assumes supply relief dominates, but ignores that Brent's path below $80 could stem from demand contraction rather than Hormuz reopening. That scenario would accelerate Fed cuts while simultaneously pressuring earnings growth and equity multiples, especially with S&P already net long above 5. The article's PCE softness then becomes a lagging indicator, not a leading one, leaving the bullish tilt exposed if global PMI data softens further in coming weeks.
"Oil falling on demand contraction, not geopolitical relief, flips the bullish narrative into a recession signal masked by rate cuts."
Grok's demand-contraction scenario is the crux nobody's stress-tested hard enough. If PMI rolls over *before* Hormuz reopens, oil falls on recession fears, not supply relief—and the Fed cuts into weakness, not strength. That's bearish equities even with lower rates. The article assumes supply shock; Grok's right that demand shock inverts the entire thesis. We need Q1 PMI data to disambiguate, but positioning above 5 on the S&P leaves no margin for that miss.
"The potential for unfreezing Iranian assets introduces a fiscal liquidity factor that overrides the simple supply-side oil narrative."
Claude and Grok are fixated on the supply-demand oil dichotomy, but both miss the fiscal impulse. If the US-Iran deal includes any unfreezing of assets, we face a liquidity injection that contradicts the 'recessionary cliff' thesis Gemini fears. This isn't just about oil prices; it's about the potential for localized fiscal stimulus in the Middle East. If the Fed cuts while liquidity expands, the S&P 500's current positioning isn't just 'fragile'—it's a coiled spring for a melt-up.
"A demand-driven oil drop without Hormuz reopening would push earnings risk and valuation compression, turning the supply-relief narrative into near-term earnings disappointment."
Grok's demand-contraction path as the driver behind Brent below $80 is plausible, but it misses that earnings risk and risk premium would tighten despite lower rates, potentially triggering a larger drawdown in equities than the relief rally priced in. If PMI weakens before any Hormuz reopening, the Fed cuts may come late and valuation compression could dominate, turning a supply-relief narrative into near-term earnings disappointment.
