The AI-Capex Race and the Economic Implications

    Macro

    • Monday’s announcement of deal between OpenAI and Advanced Micro Devices provides another reminder that the boom in artificial intelligence capex appears to be on a parabolic trajectory. At this point, the leading tech companies are on pace to invest nearly $400B this year on the infrastructure needed to build and train AI models. With an estimated cumulative total of up to $7T globally by 2030, the expected capex is set to be among the largest on an industrial scale in history. The size of the investments also provide context to our recently published economic scenarios, which places a greater weight on the right tail of the distribution relative to the left side.
    • With U.S. real GDP growth of about 1.5% in Q2 2025, data center related capex accounted for about 35% of that growth, and that share may climb to more than 50% through the second half. When factoring in growth multipliers and spillovers, AI capex investments have the potential to rival the productivity boom from the late 1990s.
    • Indeed, anecdotal studies suggest a median productivity uplift of about 30% in instances where generative AI has been deployed, and when applied to the current productivity baseline of 1.8%, that could amount to a productivity increase of 50 bps. The Congressional Budget Office indicated that a sustained uplift of that magnitude could reduce its projected debt-to-GDP from 156% over its extended baseline to 113% over the same timeframe.        
    • The surge in AI-related capex eventually points to the ongoing sustainable-boom or looming-bust debate, and we see several points on each side. In terms of the boom, the demand is being driven by highly profitable firms with low leverage and dominant market positions. Furthermore, initial signs indicate the potential for rapidly accelerating adoption on a global scale considering a low marginal cost of deployment amidst the fixed assets already in place. Finally, the geopolitical race for AI supremacy will only intensify over time with the U.S. and China likely vying for the lead.
    • On the flip side, at this point, AI-related revenues are still only a fraction of the capex thus far, questions linger about stranded assets given the investments, and potential spillover effects to constituents include electricity prices and potential labor force displacement.      

    Developed Market Rates

    • Developed market yields generally declined by less than 10 bps last week, including those in the U.S. as they usually do during partial shutdowns of the Federal government. Online markets are indicating a potential shutdown lasting 11-35 days as the most likely outcome in terms of a timeframe.
    • Despite the relative quiet on the trading and data front, there were some interesting anecdotal observations from last week. A significantly large call buying program was executed last week, implying an expectation for the U.S. 10-year yield to potentially drop below 4%. The buyer reportedly spent $200M in premium to set the position.
    • In the MBS market, mortgage volatility continues to decrease as spreads tightened modestly. Origination has slowed after a recent rate decline, helping firm up the market.       

    IG Corporates

    • In the U.S., the IG corporate index tightened 1 bp, with most underlying spreads unchanged or 1-2 bps tighter. By sector, autos outperformed (5-6 bps tighter) due to good sales results in September and potential tariff relief. In terms of deals, Occidental Petroleum bonds tightened by 15 bps after a $9.7B sale of OxyChem to Berkshire Hathaway was announced last week. A portion of the proceeds from the sale ($6.5B) will be used to reduce debt.
    • Last week's issuance dropped off dramatically to ~$16B, but demand remained robust. Deals were 3.2x oversubscribed and came with a 1-bp concession (on average). On the retail side, inflows exceeded $10B. Meanwhile, dealers bought about $800M, primarily in short term paper, but were net sellers across the rest of the IG curve.
    • The EUR IG Index moved 2 bps tighter last week to end at OAS+77. Primary markets issued just over €11B on the week. Deals continued to price with little to no concessions as issuers opted to take 30 to 45 bps off initial price talks (IPT). Next week (and for the rest of October), supply will be subdued as issuers enter their earnings blackout period.
    • The market is largely indifferent to the French political situation unless it escalates further. The current gridlock is expected to persist, and any legislative election would likely maintain the status quo. While the OAT-Bund spread widened by 7- 8 bps, the impact on the corporate market has been minimal. French banks were only 2-3 bps wider last week. In addition, there is strong support for non-bank corporates. For example, Engie (a multinational French utility) issued corporate hybrid bonds. These bonds managed to tighten by 50 bps despite political uncertainty.

    Leveraged Finance

    • U.S. HY bond spreads widened modestly under the pressure of continued heavy issuance, though the technical environment held firm overall. HY absorbed its fifth consecutive week of over $9B of issuance—its most active stretch since April 2021. Last week's volume of $11.2B across 14 deals brought September's issuance to $58.8B, the third busiest month on record. Meanwhile, retail demand resumed, with $1.2B of inflows last week, which brings YTD flows to $15.8B.
    • All credit tiers saw positive returns, with BBs outperforming on a risk-adjusted basis, while CCCs saw the most gains. Industry performance was mixed, with cable, consumer products, and telecom edging positive, while air transportation, paper, and financials were the softest on slightly negative performance.
    • § U.S. loans gained slightly for the week as the primary market took a notable breather while secondary activity was muted. The percentage of loans trading at, or above, par eased to a six-week low of 35%. Only $5.8B across five transactions syndicated last week, well below the three-week average of $28B. Flows were positive for a third consecutive week and robust CLO issuance continued.
    • European HY bonds and leveraged loans remained stable, with CCCs tightening, but BBs and Bs edging wider. Although the primary market remained active—€4B in HY bonds and €8B in loans, and both markets seeing approximately €1B each of new money—the pace of issuance was not enough to offset ongoing inflows and strong CLO issuance. Also, with approximately 60% of the European loan market trading at or above par, repricing is likely to be a theme over the coming weeks.  

    Emerging Markets

    • EM hard currency spreads tightened modestly last week, with outperformance in single-Bs. From an idiosyncratic perspective, Argentina underperformed on concerns around FX policy and other electoral noise, but the bonds bounced back mid-week on indications that U.S. support is forthcoming. Pemex outperformed after it was upgraded to BB+ by Fitch. Romania, which issued 4B euro, lagged. There was also new issue from single-B-or-lower issuers Kenya, Egypt, and Bahrain. If the broader narrative remains supportive, we expect to continue to see strong performance, but risks remain. Balancing tail risks with attractive idiosyncratic stories and selective relative value opportunities, it seems appropriate to continue with risk and focus on identifying bottom-up stories.
    • EMFX rebounded last week, with Europe and Asia outperforming. EGP, IDR, HUF, TRY, and ZAR all had strong weeks. Lower Treasury rates allowed lower-carry currencies to post positive returns. THB was an exception as the currency lost ground after the government announced that taxes on gold trading are likely to increase. MXN was another laggard on the back of U.S. labor market softness. While the USD has remained rangebound, we believe there is scope for it to weaken over the medium-term if the Fed cuts quicker and/or more than what is currently priced in.
    • In EM local rates, the Index rose modestly. Brazil came under pressure and the curve bear steepened after Lula requested a study to eliminate bus fares. A higher-than-expected inflation print in Turkey caused a mild selloff in local bonds. Mexico and Peru yields also rose. Colombia and Indonesia outperformed.
    • EM corporate spreads widened slightly amid a noticeable shift from broadly constructive to cautious on lower-rated issuers, especially in Turkey and Argentina. The idiosyncratic noise has been elevated with the Ambipar fraud and the Turkish investigation of the Ciner group. Turkish corporates were wider last week with the renewable names significantly underperforming. Brazil corporates tightened after underperformance the prior week, with the view on Braskem changing from a Novonor-driven reprofiling to the banks and Petbra taking over the company. In terms of new issues, the activity has slowed given the turmoil in the market and we have no appetite for participating unless there is a significant concession.   

    Securitized Products

    • Primary SASB floating-rate AAA and subordinate tranches tightened, while fixed rates held firm with benchmark office names. AAA conduits and CRE CLO spreads were both unchanged, although subordinate conduit tranches edged wider. Five primary market deals priced—two SASB, one conduit, agency, and CRE CLO, respectively. The SASB pipeline remains robust and the uptick in CRE CLO issuance continues on tightening spreads.
    • In RMBS, non-QM spreads tightened on renewed demand, while second-lien spreads were flat and CRTs were range bound in elevated secondary trading driven by FNMA's tender offer. Elevated issuance continued, with nine primary deals totaling $3.5B pricing, bringing September and YTD volumes to $18B and $132B, respectively. September's volume includes a monthly record for non-QM and second liens.
    • Benchmark AAA U.S. CLO spreads continued to tighten, while mezzanine tranches softened further under the weight of elevated supply. The benchmark vs. non-benchmark basis further compressed as demand for non-benchmark profiles continues. Primary issuance was $13.2B across 29 deals in the U.S. and €4.2B priced across nine deals in Europe. The U.S. saw 13 resets, six new issues, and 10 refi's, while Europe saw three new issues, six resets.
    • ABS spreads were mixed—unchanged at the top of the stack, but wider at the bottom, especially among non-prime sectors. While primary order books have been weaker, deals are generally clearing in the context of price guidance. We believe the market will have a better sense of performance as heavy new supply prices over the coming weeks. With the uptick in U.S. issuance already in the pipeline, elevated primary activity in Europe and Australia is expected to continue.

    Municipal Bonds

    • Last week, the muni curve bear flattened, with the front-end underperforming Treasuries. 5-year, 10-year, and 30-year M/T yield ratios ended the week at 62%, 71%, and 89%, respectively. While last week's primary deals generally had strong performance, short maturities continued to lag. This week, issuance is expected to reach ~$14B. Absent major catalysts, we expect technicals to remain supportive. Roughly $21B in reinvestment flows are expected for the month of October.
    • In our portfolios, we maintain a cautious stance regarding exposure to local governments given escalating tensions between local governments and the White House. Notably, $18B in loans to New York and $2B to Chicago have been halted in the shutdown.
