Global Credit: Trading Strategies under Oil and Interest Rate Scenarios
UBS believes current credit spread valuations are already tight, leaving limited room for further narrowing; it advises positioning across three scenarios based on Middle East developments and inflation paths, and to take profits on long positions in European vs U.S. credit spreads.
- Over the past two months, U.S. and European investment-grade/high-yield credit spreads have narrowed by 17/60bp and 18/69bp respectively
- U.S. credit spreads have shown resilience to rising interest rates due to inflation expectations remaining below the 2.5% threshold
- If breakeven inflation rises to 2.65-2.75%, U.S. credit spreads could widen significantly
- European credit faces higher risk: ECB rate hikes, weak growth, limited fiscal support
- U.S. and European IG/HY spread valuations are at historical extremes (U.S. IG/HY at 2%/3% percentiles)
- Institutional investors' long credit positions are near historical highs, limiting further narrowing potential
- Suggests different trading strategies under three oil price and interest rate scenarios
Report interpretation
Overview
This UBS global strategy report explores the performance logic and future trading strategies of the global credit market—especially in the U.S. and Europe—against the backdrop of rising global interest rates and Middle East geopolitical conflicts. The report notes that despite higher interest rates, credit spreads remain tight, mainly driven by manageable inflation expectations, solid fundamentals, and technical support. However, current valuations are extremely stretched, compounded by crowded investor positions, limiting further narrowing potential. The report proposes three scenarios based on oil prices and inflation trends, offering corresponding trading recommendations, and announces the closure of previous long positions in European credit relative to U.S. credit.
Core views
The report first explains why credit spreads have maintained resilience in a rising interest rate environment: the rise in the 10-year U.S. Treasury yield is primarily driven by real rates and maturity risk premium rather than runaway inflation expectations; meanwhile, the 'AI productivity enhancement' narrative has strengthened long-term growth outlooks. While inflation expectations have shown signs of rebounding, they still remain below the critical 2.5% threshold. The report sets a key warning line: once U.S. breakeven inflation enters the 2.65-2.75% range, market confidence in the Fed's control over inflation will be questioned, potentially triggering a paradigm shift in monetary policy (from 'adjustive hiking' to 'multiple rounds of hiking'), which would cause credit spreads to widen nonlinearly. Recent increases in the supply chain pressure index (1.2 standard deviations from March to April) have intensified this risk. In contrast, European risks are more pronounced. The ECB is about to hike rates, with the market pricing in around 60 basis points of rate hikes by 2026. However, weak economic growth due to energy shocks, and limited corporate fiscal support, have yet to be fully priced into credit spreads. At the valuation level, the report believes the credit market is extremely expensive. U.S. investment-grade/high-yield spreads are at the 2nd/3rd percentiles over the past year, while Europe sits at the 30th/11th percentiles. Investor positions are also approaching extreme levels: using S&P 500 futures as a proxy, asset managers’ net long positions are at the 95th percentile over the past decade; CTA (commodity trading advisor) credit long positions peaked in May. Historical data shows that after geopolitical crises resolve, when CTAs previously shorted credit, spreads narrowed most significantly. Given that CTAs are currently long, even if peace agreements are reached, further narrowing of spreads will be limited.
Analysis framework
UBS’s analytical framework combines macro drivers, valuation positioning, and flow of funds (positions) across three dimensions. First, by decomposing the components of interest rate movements (real rates, inflation expectations, maturity premium), it evaluates their transmission intensity to the credit market. Second, it uses historical percentiles to assess current credit spread valuations and observes internal consistency through sector-level data. Finally, it incorporates position data from asset managers and CTAs as contrarian indicators to gauge the extremity of market sentiment and its constraints on future price movements. Based on this, the report employs scenario analysis to address high uncertainty. For two core variables—the trajectory of Middle East conflicts (whether the Strait of Hormuz remains disrupted) and the nature of inflation (sticky or transitory)—three mutually exclusive scenarios are constructed, each matched with specific convex trading strategies (e.g., shorting specific REITs or going long specific sectors). This approach avoids reliance on a single forecast path and better suits today’s complex macro environment.
Methodology notes
Setting key thresholds (e.g., breakeven inflation at 2.65-2.75%) as triggers for credit market responses
The report argues that markets are insensitive to gradual changes but become highly reactive when a key indicator crosses a critical threshold, prompting fundamental questioning of macro narratives and leading to nonlinear asset price adjustments. This helps identify potential 'trigger points'.
Using historical percentiles to evaluate relative valuation of assets
By comparing current credit spreads with their historical distribution over the past year (e.g., at the 2nd percentile), one can visually determine whether they are overvalued, providing a basis for mean reversion strategies.
Using institutional investor (e.g., CTA) positions as leading indicators of market sentiment and future returns
The report points out that when a certain type of investor (e.g., CTAs) reaches an extreme position level, their subsequent adjustment space is constrained, often signaling a reversal or stagnation in asset prices—a classic application of contrarian thinking.
Breaking down the drivers of interest rate movements (real rates vs. inflation expectations) to analyze differential impacts on credit
Not all interest rate increases are detrimental to credit. Rate hikes driven by real rates may reflect strong economic activity, whereas those driven by inflation expectations threaten corporate profitability and debt servicing capacity. This breakdown helps pinpoint the precise source of risk.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- U.S. Investment Grade Office REITsShort in the 'Energy Normalization but Sticky Inflation' scenario (oil prices falling, interest rates rising)
- Weaknesses
- Long cash flow duration, higher leverage than other REITs, liquidity premiums increase during stress periods
- Comparison
- Compared to other REIT sub-sectors, performs poorly during stress periods
- Risks
- If interest rates do not rise as expected, this short position may incur losses
- European Investment Grade AirlinesLong in the 'Energy Normalization and Transitory Inflation' scenario (oil prices falling, interest rates falling)
- Strengths
- Underpriced since end-March (~14%), positive spreads, slightly longer duration structure offers convexity
- Comparison
- Among European IG sectors, airlines and REITs were among the two sectors lagging in recent rebounds
- Risks
- If inflation is not transitory, this long position may underperform
- U.S. High-Yield RetailShort in the 'Strait Disrupted and Sticky Inflation' scenario (oil prices surging, interest rates rising)
- Weaknesses
- Highly sensitive to consumer spending, especially vulnerable under K-shaped economy and negative growth shocks
- Comparison
- Compared to the index, this sector tends to underperform in consumer weakness environments
- Risks
- If consumer resilience continues to exceed expectations, this short position may incur losses

Impact & implications
The core message of the report is that the global credit market lacks near-term upside catalysts and instead faces downside risks. Investors should shift from 'Beta' strategies focused on spread tightening to more selective 'Alpha' strategies. Specifically, they should reduce exposure to the overall credit market and focus on niche areas with asymmetric returns (convexity) under specific macro scenarios. Additionally, the report clearly expresses a bearish view on European credit relative to U.S. credit and recommends closing relevant long positions.
