Monthly Review - July was defined by a broad selloff in developed-market rates as investors continued to assess the durability of growth, inflation, and restrictive monetary policy.

Government bond yields rose across most major markets, while inflation expectations moved higher and U.S. curves steepened. Spread sectors were more mixed: U.S. credit widened modestly, European investment grade remained resilient, and securitized products absorbed higher rates with only limited deterioration in credit spreads.
The rates move was global. The U.S. 10-year Treasury yield rose 27 basis points (bps) to 4.73%, while 10-year yields increased 35bps in Germany, 29bps in the UK, 28bps in Canada, and 32bps in New Zealand. In the U.S., the selloff was accompanied by curve steepening, with the 2s10s spread widening 15bps and the 5s30s spread increasing 10bps. Inflation expectations also rose, with 10-year breakevens increasing 5bps in the U.S. and by roughly 17 to 20bps across several European markets. These moves reflected continued uncertainty around the path of monetary policy, particularly as positive growth data and lingering inflation risks limited the scope for near-term easing.
The Federal Reserve’s month-end meeting added to that uncertainty. The Committee left rates unchanged despite three votes in favor of a 25bps hike, creating a hawkish vote split but a more measured policy signal. Chairman Warsh emphasized the tightening already delivered by higher market yields and suggested the Fed was willing to preserve flexibility rather than lead expectations with a more forceful inflation message. Markets interpreted the reaction function as comparatively dovish: the yield curve steepened, September policy expectations repriced, and breakevens moved higher. The response suggested investors viewed the Fed as prepared to let financial conditions do part of the tightening work, while remaining less explicit about what would trigger direct policy action.
Foreign exchange markets partially reversed June’s U.S. dollar strength. The broad dollar index declined approximately 1.3%, while the yen, sterling, Norwegian krone, and New Zealand dollar appreciated. Emerging-market currency performance was highly differentiated, with notable strength in the Colombian peso and Korean won, while the Hungarian forint, Turkish lira, and Egyptian pound weakened.
Credit markets remained orderly despite higher government bond yields and historically tight valuations. U.S. investment grade spreads widened 4bps to 78bps OAS, with industrials modestly underperforming financials and utilities. Longer-duration yields moved above 6%, increasing the all-in income available from high-quality corporate credit, though elevated issuance and tight starting valuations contributed to greater investor selectivity. Euro investment grade proved more resilient, tightening 1bp to 79bps, with modest outperformance from industrials and utilities. The regional divergence reinforced the importance of market and sector selection rather than broad credit beta.
High yield experienced somewhat greater pressure. U.S. high yield spreads widened 9bps to 279bps, led by a 56bps move in CCC-rated debt, while BB and single-B spreads moved more modestly. Euro high yield widened only 3bps to 272bps, although single-B credits underperformed. Primary activity and AI-related financing remained important themes, but investors continued to distinguish sharply between established businesses offering attractive carry and more speculative data center or technology-related issuers.
Leveraged loans remained characterized by substantial dispersion. Software continued to trade at a significant discount to the broader market, reflecting persistent concerns around AI disruption, refinancing, and the transparency of private-market valuations. At the same time, stronger CLO demand created selective opportunities in higher-quality software issuers with mission-critical products, shorter maturities, and stronger switching costs. The broader theme remained one of improving opportunities beneath a market that still required disciplined issuer selection.
Securitized markets faced pressure primarily from the rise in rates rather than a meaningful deterioration in credit fundamentals. Agency Mortgage-Backed Security (MBS) yields increased 33bps to 5.75%, while spreads widened 9bps to approximately 116bps versus comparable Treasuries. Thirty-year mortgage rates rose to 6.73%. By contrast, spread movements across securitized credit remained modest: agency CMBS and AAA CMBS widened only 1bp, while AAA Asset-Backed Securities (ABS) tightened slightly. Stable housing fundamentals and improving commercial real estate occupancy continued to support underlying credit performance, although higher rates and heavy issuance constrained broader spread tightening.
Emerging markets (EM) were mixed as global yields rose and country-specific developments remained the primary source of differentiation. External sovereign spreads widened 10bps to 227bps, with the Middle East underperforming as regional risk premia remained elevated. EM corporate spreads widened only modestly, while local yields rose across many markets, including Hungary, Poland, South Africa, Mexico, Indonesia, and South Korea. Political developments and policy measures in markets such as Colombia and India continued to create idiosyncratic opportunities despite the less supportive global rates backdrop.
Overall, July marked a shift from the relative stability of June toward renewed pressure from higher global yields. Fixed income markets remained functional and technical demand continued to provide support, but the combination of rising rates, tight spreads, and growing dispersion reinforced the importance of carry, relative value, and active security selection.
Investing in companies in anticipation of a catalyst event, such as AI adoption, carries the risk that such catalysts may not occur, may be delayed, or that the market may react differently than expected. Companies focused on AI may have limited product lines, markets or financial resources, and their management and performance may be particularly impacted by events that adversely affect AI adoption, such as rapid changes in product technology cycles, product obsolescence, government regulation, cybersecurity concerns and competition.
