Research Digest — today (2026-09-25)

Verdict

The sell-off is predominantly a real-yield and neutral-rate repricing, not a re-rating of long-run inflation expectations, which changes which assets are most exposed and which are most insulated.

Analysis

DB's decomposition is the load-bearing evidence: US 10-year nominal yields are up around 97bp year-to-date, only around 10bp of which is due to higher breakevens, with the remainder reflecting significantly higher real yields now at levels last seen in 2008 (P004). DB also notes that 10-year breakevens have been remarkably stable for more than three years and that term premium measures have remained range-bound over the past 18 months, which points the causal mechanism toward policy rates and a higher neutral rate rather than fiscal-risk repricing (P004). ING's rates desk reaches the same conclusion from the auction side, describing the driver as predominantly higher real yields and noting that this is not shielded by the Fed hiking rates, which would be the case if there were an inflation-expectations problem (P017). Natixis supplies the level check: the 10-year US real rate at 2.85%, its highest since December 2008, against 10-year breakevens at 2.3% (P025). The counterargument comes from Nordea, which argues that the cyclical case for yields to rise further has clearly weakened because markets are already pricing in clearly more tightening from both the Fed and the ECB than in its baseline forecasts (P026), and from DB's own morning note, which says it feels breakevens are too low and real yields might be getting too high (P005). The investor consequence is that long-duration equity valuations, real-estate and utility cash flows, and low-carry currencies are the transmission points, while inflation-linked exposure is not where the stress is showing up.

Tension

DB and ING read the move as a real-yield/neutral-rate repricing with contained inflation expectations (P004, P017), while Nordea argues the cyclical case for further yield rises has clearly weakened because markets already price more tightening than its baseline (P026).

What changed

The composition of the yield move: nominal yields at post-2007 highs with breakevens stable, so the marginal driver shifted from inflation compensation to real rates and neutral-rate repricing (P004, P005, P025).

Desk views

DB decomposes the 2026 nominal yield rise and finds only a small breakeven contribution, pointing to policy rates and a higher neutral rate.

Evidence IDs · P004

ING's rates desk sees the overshoot toward 5.25%-5.5% on the US 10yr as real-yield driven, with inflation expectations relatively contained and rate-hike fears already discounted.

Evidence IDs · P017

Natixis contrasts the stability of long-term inflation expectations with the real rate driving nominal yields higher.

Evidence IDs · P025

Nordea argues the cyclical case for further yield rises has weakened because markets already price more Fed and ECB tightening than its baseline.

Evidence IDs · P026

Investor implication

If the move is real-yield-led, the pain is concentrated in long-duration equity valuations, rate-sensitive sectors and low-carry currencies rather than in inflation-linked assets; a correction lower in yields, which Nordea argues cyclical considerations already support (P026), would relieve those same exposures first.

Invalidation

A sustained fall in real yields alongside stable breakevens would undercut the real-yield-led thesis; a rise in breakevens would shift the diagnosis toward inflation expectations (P004, P025).

Verdict

USD strength this month is closely explained by the front-end rate move, and CACIB sees seasonal patterns and option-market pricing as consistent with the rally having longer legs, while ING is more cautious about calling the end of the rally but still sees downside risks for EUR/USD.

Analysis

CACIB's mechanism is explicit: the 2Y SOFR is on track for its largest monthly rise in years, above 50bp, registering fresh two-year highs, and this single variable seems to explain a great deal of this month's G10 FX performance, with the ranking order closely following each currency's beta to 2Y USD rates (P001). CACIB adds that USD strength appears only a tad more pronounced than the regressions imply, that the NZD has lagged the most while the JPY has fared much better as threats of FX interventions have likely acted as a strong backstop, and that seasonal patterns suggest the rally could have longer legs in the month ahead (P001). ING's FX desk frames the dollar as benefiting from the knock-on effect of the bond sell-off on global risk sentiment, allowing a consolidation of recent gains even as they start to look stretched relative to short-term fundamentals, and it flags 1.1320-1.1330 as the next key support for EUR/USD (P018). ING also notes the 2-year SOFR is up almost 20bp over the past 48 hours, with pricing for October at 18bp, two hikes fully priced in by January and almost four by July 2027 (P018). The counterweight is JPM's G10 desk, which notes the DXY is in overbought territory with RSI above 70 and says it would be a better buyer of EUR here for choice, keeping an eye on the 19-month lows around 1.1330 (P020). The investor consequence is that USD strength is a rate-differential story with a risk-sentiment amplifier, not a growth-differential story, so it is most vulnerable to a front-end repricing rather than to a growth disappointment.

Tension

CACIB sees the rally as not particularly overstretched with a seasonal tailwind (P001), while JPM's desk flags DXY overbought conditions and prefers buying EUR (P020).

What changed

The front end led: 2Y SOFR on track for its largest monthly rise in years, above 50bp, with fresh two-year highs (P001).

Desk views

CACIB attributes this month's G10 FX performance to the 2Y SOFR move and sees seasonal patterns and option pricing as consistent with a longer USD rally.

Evidence IDs · P001

ING's FX desk sees the dollar consolidating gains via the risk-sentiment channel of the bond sell-off, remains cautious about calling the end of the rally, and flags EUR/USD support at 1.1320-1.1330.

Evidence IDs · P018

JPM's G10 desk notes DXY RSI above 70 and prefers buying EUR, watching the 19-month lows around 1.1330.

Evidence IDs · P020

Investor implication

Because the driver is the front end, a pause or reversal in 2Y USD rates would be the fastest route to relieving USD pressure; CACIB's seasonal argument (P001) and ING's stretched-valuation caveat (P018) point in opposite directions on timing.

Invalidation

A front-end repricing lower in 2Y USD rates would remove the mechanism CACIB identifies as explaining most of this month's G10 FX performance (P001).

Verdict

The franc and the krona are being driven primarily by global rate differentials rather than domestic fundamentals, and UBS expects that to persist through year-end even where domestic stories are improving.

Analysis

UBS's CHF work is explicit that wide yield differentials continue to weigh on the CHF and support its use as a funding currency, with the franc weakened by around 5% on a broad basis since the onset of the Middle East conflict and struggling to attract inflows given its near-zero yield (P028). UBS adds that the SNB left its policy rate unchanged and did not adopt an overly hawkish tone, and that its economists now expect rate hikes in March and June 2027, bringing forward the first increase from mid-2027 (P028). The SNB's own language shift matters: it no longer has an increased willingness to intervene and moved to symmetric intervention language, noting it would be active in the foreign exchange market as necessary to ensure appropriate monetary conditions, whereas previously its interventions were aimed at countering a rapid and excessive appreciation of the Swiss franc (P015). On the krona, UBS argues the currency continues to be driven primarily by global rates dynamics rather than domestic fundamentals, with Sweden's economy relatively resilient but elevated energy prices, comparatively low interest rates and expectations for further Federal Reserve tightening weighing on the currency (P030). GS's Riksbank note supplies the policy detail: the policy rate was kept unchanged at 1.75%, the Executive Board guided that increases in the policy rate will begin this year, the policy rate path was lifted notably for 2027-2029 peaking at 2.43% in 2028Q1, and GS continues to expect a hike in December with November possible (P014). The counterargument is that UBS itself believes markets have become overly hawkish on rates (P028) and that the anticipated SNB hikes should gradually reduce the franc's yield disadvantage (P028), while UBS's SEK note says a more supportive backdrop for the krona would require Fed hikes being fully priced out (P030). The investor consequence is that carry-oriented positioning in these currencies is a bet on the global rate cycle turning, not on domestic data.

Tension

UBS sees the CHF and SEK as carry-driven and expects the pressure to persist through year-end (P028, P030), while it simultaneously argues markets have become overly hawkish on rates, which would be the condition for relief (P028).

What changed

The SNB dropped its increased-willingness-to-intervene language in favour of symmetric intervention language (P015), and the Riksbank's policy rate path was lifted notably for 2027-2029 (P014).

Desk views

UBS attributes CHF weakness to wide yield differentials and near-zero yield, expects SNB hikes in March and June 2027, and retains EURCHF around 0.94 through year-end with near-term upside risks.

Evidence IDs · P028

GS reports the SNB held at 0.0% for the sixth consecutive meeting and shifted to symmetric intervention language.

Evidence IDs · P015

UBS argues the krona is driven primarily by global rates dynamics rather than domestic fundamentals despite a hawkish Riksbank tone.

Evidence IDs · P030

GS reports the Riksbank held at 1.75% with hawkish guidance, a lifted policy rate path peaking at 2.43% in 2028Q1, and expects a December hike.

Evidence IDs · P014

Investor implication

Relief for the franc and krona requires either Fed hikes being fully priced out or a narrowing of rate differentials via SNB and Riksbank tightening; until then, carry economics keep both currencies on the back foot (P028, P030).

Invalidation

A material narrowing of rate differentials, or Fed hikes being fully priced out, would remove the carry mechanism weighing on both currencies (P028, P030).

Verdict

The yen is outperforming on intervention rhetoric even as the underlying rate differential remains adverse, making the currency a policy-risk trade rather than a carry trade.

Analysis

MUFG reports that the yen is already the top performer on comments made by Finance Minister Katayama and Growth Strategy Minister Kiuchi in Tokyo, with Katayama's comment that President Trump expressed concern over yen weakness clearly underlining ongoing efforts in Tokyo to portray the efforts to stem yen weakness as a continued joint strategy (P024). MUFG adds that this reinforces the possibility that additional intervention could again include the US, and that it is unusual for the US to act jointly with Japan beyond one occasion, so acting jointly again would be a strong message to the markets (P024). CACIB's FX work provides the corroborating detail from the other side: the JPY has been able to actually fare much better than its rate beta would imply, as threats of FX interventions have likely acted as a strong backstop (P001). The counterargument is that the underlying drag is real: MUFG notes the yen weakened in response to the BoJ meeting, which it attributes more to excessive hawkish pricing than to Governor Ueda communicating a dovish message (P024), and JPM's G10 desk describes the setup as last chance saloon stuff with evidence of more local interest, including two spicy USDJPY Tokyo benchmarks and JPY demand from different local RM accounts (P020). The investor consequence is that short-yen carry positions now carry a policy tail risk that is not captured by the rate differential alone, and the market's sensitivity to Tokyo rhetoric is elevated.

Tension

Intervention rhetoric is supporting the yen (P024, P001) while the rate differential and BoJ pricing dynamics continue to weigh on it (P024, P020).

What changed

Katayama revealed Trump's concerns over yen weakness, reinforcing the possibility of joint intervention (P024).

Desk views

MUFG reports the yen as top performer on Katayama's comments and sees joint US-Japan intervention as a possibility that would send a strong message.

Evidence IDs · P024

CACIB notes the JPY has fared much better than its rate beta implies because intervention threats have acted as a strong backstop.

Evidence IDs · P001

JPM's G10 desk describes the USDJPY setup as last chance saloon with evidence of more local interest and JPY demand.

Evidence IDs · P020

Investor implication

The yen's near-term path is now more sensitive to Tokyo and Washington rhetoric than to the rate differential, which raises the cost of carrying short-yen positions without a policy hedge (P024, P001).

Invalidation

A credible US-Iran de-escalation that lowers oil and UST yields would change the backdrop MUFG identifies as the reason intervention efficacy is in question (P024).

Verdict

The energy shock is shifting from a midyear disinflationary impulse into a renewed source of upward pressure, and the pass-through to core inflation is the key variable that determines how far central banks extend tightening.

Analysis

JPM's global inflation monitor is the most detailed evidence: energy prices are shifting from a disinflationary impulse at midyear into a renewed source of upward pressure, with the global energy CPI ex China and Türkiye up 1.6% m/m in August, and against a backdrop of resilient growth, persistently elevated energy prices are raising the risk of broader spillovers to core inflation beyond transportation prices, a risk central banks are increasingly responding to (P021). JPM also notes that large increases in the flash DM input and output price indexes in September confirm a further buildup in price pressures, and that while higher energy costs account for part of the latest increase, the details support the view that resilient global growth is strengthening firms' pricing power (P021). GS's APAC monitor adds the regional dimension: energy prices have moved meaningfully higher again over the past several weeks, which should be reflected in further increases in import prices and producer prices in September in many economies, though to a lesser extent in final consumer prices given fiscal subsidies and regulated prices in many cases (P006). GS also notes that before the ongoing Iran war, CPI inflation was broadly in line with or below central bank targets in most countries, and now headline and core CPI inflation are generally in line with targets or above (P006). UniCredit supplies the eurozone micro-foundation: business confidence has remained resilient while consumers have become more pessimistic, a divergence it attributes mainly to a strengthening of firms' pricing power in a world where supply-side shocks tend to occur more often (P034). The counterargument is that pass-through has been limited so far: GS notes that at the regional level median core inflation has edged up only slightly (P006), and JPM notes that while PMI price measures have moderated from their early-conflict highs, they remain elevated (P021). The investor consequence is that the energy shock is now a pricing-power story as much as a commodity story, which matters for margin durability in consumer-facing sectors and for the pace of central bank tightening.

Tension

JPM and UniCredit see broadening price pressures and stronger firm pricing power (P021, P034), while GS notes pass-through to core CPI has been relatively limited so far (P006).

What changed

Energy shifted from a midyear disinflationary impulse into a renewed source of upward pressure, with the global energy CPI ex China and Türkiye up 1.6% m/m in August (P021).

Desk views

JPM sees energy shifting into a renewed source of upward pressure and warns of broader spillovers to core inflation, with resilient growth strengthening firms' pricing power.

Evidence IDs · P021

GS reports energy prices moving meaningfully higher again with expected pass-through to import and producer prices, while noting core pass-through has been relatively limited so far.

Evidence IDs · P006

UniCredit attributes the divergence between resilient business confidence and pessimistic consumers to strengthening firms' pricing power under supply-side shocks.

Evidence IDs · P034

Investor implication

If firms' pricing power is strengthening, the energy shock transmits into core inflation and keeps central banks on a hiking path, which in turn reinforces the real-yield dynamic driving the bond sell-off (P021, P034).

Invalidation

A sustained fall in energy prices, or evidence that core inflation remains contained despite elevated energy costs, would undercut the broadening-price-pressure thesis (P006, P021).

Verdict

France's debt trajectory is deteriorating, and GS sees a self-reinforcing risk where higher debt entails higher rates and lower growth, though it also flags encouraging signs in the fiscal debate ahead of next year's elections.

Analysis

GS's mechanism is explicit: the trajectory of France's public debt is looking increasingly challenging given the lack of progress in reducing the deficit and the recent increase in borrowing costs, and GS now estimates France will eventually need to run a 1% primary surplus to stabilise its public debt-to-GDP ratio, a feat rarely achieved in recent history (P008). GS revises its public debt forecast to 125% of GDP by the start of the next decade, versus 123% before, and warns that the longer public debt remains high and increasing, the more likely it is France will face durably higher borrowing costs, which could lead to self-reinforcing pressures where higher debt entails higher rates, lower growth, and ultimately even higher debt (P008). The market-level corroboration comes from ING, which notes French 10-year yields are trading 110bp above bunds and that there has been little relief from reports that Marine Le Pen may back the proposed budget to avert a bond crisis (P018). Natixis reports the OAT-Bund spread tightened slightly to 109bp with no clear direction during the European session, and later at around 107bp (P025). The counterargument is that GS itself notes more encouraging signs: recent polls suggest economic and fiscal issues have risen to the top of voters' concerns with a large majority in favour of reducing public debt, the deficit and spending, and both Marine Le Pen and Edouard Philippe have started making the case for reforming France's fiscal framework (P008). The investor consequence is that French sovereign risk is now a spread story with a political catalyst calendar, and the self-reinforcing mechanism GS describes means the cost of delay compounds.

Tension

GS's debt-trajectory warning (P008) sits against its own observation of encouraging signs in the fiscal debate and voter preferences (P008), while ING notes little relief from political headlines (P018).

What changed

GS revised its public debt forecast to 125% of GDP by the start of the next decade, versus 123% before (P008).

Desk views

GS revises France's debt forecast higher and describes a self-reinforcing mechanism where higher debt entails higher rates and lower growth, while flagging encouraging signs in the fiscal debate.

Evidence IDs · P008

ING notes French 10-year yields trading 110bp above bunds with little relief from political headlines.

Evidence IDs · P018

Natixis reports the OAT-Bund spread tightening slightly to 109bp with no clear direction during the European session.

Evidence IDs · P025

Investor implication

French sovereign risk is a spread story with a political catalyst calendar; the self-reinforcing mechanism GS describes means the cost of fiscal delay compounds, and the election-related reform signals are the main offsetting variable (P008).

Invalidation

A credible fiscal consolidation path, or a narrowing of the OAT-Bund spread, would undercut the self-reinforcing debt-cost mechanism GS describes (P008, P018).

Verdict

AI infrastructure demand is broadening beyond GPUs, but execution risk in hyperscale data-centre builds is becoming more tangible, which changes the risk profile of third-party-developed AI infrastructure.

Analysis

GS's TMT desk supplies the two-sided evidence. On the risk side, Oracle reportedly issued a force majeure notice to the Blue Owl-backed developer of Project Jupiter in New Mexico, and while investors did not read this as Oracle walking away from the capacity, the bigger debate it triggered is that execution risk in hyperscale AI data-centre builds is becoming more tangible, with permitting, power redesigns, community opposition and local infrastructure constraints now threatening construction timelines and financing assumptions (P016). GS adds that for Oracle the issue highlights the gap between aggressive AI capacity commitments tied to OpenAI demand and the practical challenge of delivering multi-gigawatt campuses, and that for lenders and data-centre investors it is a reminder that third-party-developed AI infrastructure is not always the bond-like asset class it can appear to be (P016). On the demand side, Anthropic signed an $11.6bn, seven-year deal for CPU capacity on Akamai's network, roughly six times larger than Anthropic's May contract with Akamai, reinforcing how broad AI infrastructure demand has become beyond GPUs (P016). GS's US strategy work quantifies the scale: the largest US AI hyperscalers are on track to spend $800 billion in capex in 2026 and consensus expects $1.1 trillion in spending in 2027, and hyperscalers need to generate annual AI revenues of roughly $300 billion in the next few years to break even on their investments (P011). GS's Pasquariello adds the market-pricing dimension: while market participants express skepticism about the durability of AI infrastructure stocks' earnings growth, that view is at least partially priced, with the median AI infrastructure stock de-rated from 32x consensus forward earnings in April 2026 to 22x today (P012). The counterargument is that the de-rating itself is evidence the skepticism is partly discounted, and Pasquariello argues the aggregate effect of the agentic revolution is positive for the equity complex and structurally disinflationary (P012). The investor consequence is that the AI infrastructure trade is bifurcating: demand visibility is broadening, but the delivery risk on multi-gigawatt campuses is now a credit and equity risk factor rather than a background assumption.

Tension

Broadening AI infrastructure demand (P016, P011) sits against tangible execution risk in hyperscale builds and the reminder that third-party-developed AI infrastructure is not always bond-like (P016).

What changed

Oracle's reported force majeure notice made execution risk in hyperscale AI data-centre builds more tangible (P016), while Anthropic's $11.6bn Akamai deal showed demand broadening beyond GPUs (P016).

Desk views

GS's TMT desk reports the Oracle force majeure notice and frames execution risk in hyperscale builds as more tangible, while noting Anthropic's $11.6bn Akamai CPU deal as evidence of broadening demand.

Evidence IDs · P016

GS's US strategy work quantifies hyperscaler capex at $800bn in 2026 and $1.1trn expected in 2027, with roughly $300bn of annual AI revenues needed to break even.

Evidence IDs · P011

GS's Pasquariello notes the median AI infrastructure stock has de-rated from 32x to 22x forward earnings, suggesting skepticism is at least partially priced, and argues the aggregate effect is positive for equities.

Evidence IDs · P012

Investor implication

The AI infrastructure trade is bifurcating: demand visibility is broadening beyond GPUs, but delivery risk on multi-gigawatt campuses is now a credit and equity risk factor, which argues for distinguishing between capacity commitments and capacity delivery (P016, P011).

Invalidation

Evidence that hyperscale build timelines are holding and that third-party-developed AI infrastructure is performing as a bond-like asset would undercut the execution-risk thesis (P016).
