Key takeaways

  • The energy transition shifts the economy toward metal- and electricity-intensive inputs, while new mining supply can take decades, forcing prices to adjust and potentially driving commodity trends and inflation.
  • Trend-following success depends on positive autocorrelation in underlying prices, and equities can exhibit negative short-horizon autocorrelation that reduces the effectiveness of generic trend signals compared with fixed income.
  • In higher-inflation environments, bonds can shift from providing CPI-plus returns to CPI-minus returns and become more correlated with equities, reducing diversification value.
  • The Japan–US yield differential narrowed materially during 2025, which may reduce the attractiveness of related carry and trend opportunities going forward.
  • Some German institutions will not invest in strategies that contain commodities even when commodities would complement fixed-income-heavy portfolios.

Commodities And Commodity Trend As Inflation Robustifier

  • The energy transition shifts the economy toward metal- and electricity-intensive inputs, while new mining supply can take decades, forcing prices to adjust and potentially driving commodity trends and inflation.
  • Even including QIS, the trend industry is small relative to major asset markets, but CTAs can be significant in some commodity markets, requiring crowding and market-impact management.
  • Commodities tend to perform well in inflationary periods but poorly in low-inflation periods, and commodity trend strategies can reduce the low-inflation drag versus passive commodities.
  • “Commodity trend” is defined as trend-following applied only to commodity markets rather than a mixed financial-and-commodity trend program.
  • Separating commodity trend from financial trend can improve allocator utility because commodities embed distinct physical risk factors and often require different trading treatment than fixed income.
  • Commodities provide diversification because non-fungibility across time, geography, and quality creates distinct price dynamics and dislocations.

Trend Following Return Drivers Asset Class Heterogeneity And Adaptive Implementation

  • Trend-following success depends on positive autocorrelation in underlying prices, and equities can exhibit negative short-horizon autocorrelation that reduces the effectiveness of generic trend signals compared with fixed income.
  • Trend followers should account for each market’s salient characteristics because those characteristics change trend dynamics even if the same broad model is used across markets.
  • Carry-like returns exist across multiple asset classes and are not unique to any single asset class.
  • Trend strategies started 2026 well, with notable trends across FX including EMFX such as Turkish lira and in smaller markets like Taiwanese rates.
  • Despite poor fixed-income trend performance over the last three years, Safi’s fixed-income-focused program reportedly had three positive years totaling about 12% net after fees, attributed to specialization and asset-class-specific implementation.
  • Autocorrelation differences are driven by participant behavior such as equity rebalancing, value trading, and options activity, and these structures can change over time, requiring ongoing adaptation.

Inflation Regime Uncertainty And Bond Diversification Breakdown

  • In higher-inflation environments, bonds can shift from providing CPI-plus returns to CPI-minus returns and become more correlated with equities, reducing diversification value.
  • The Fed cut policy rates over the last year despite inflation not being back at 2%, leaving real rates around 1%.
  • US federal debt is roughly $30 trillion and annual interest costs are around $1 trillion, materially higher than roughly $250 billion a decade earlier.
  • Deglobalization, supply-chain security efforts, and increased defense and strategic spending are secular forces likely to support structurally higher inflation.
  • Recent inflation has been driven substantially by supply shocks and supply-chain disruptions rather than being purely demand-driven.
  • Inflation tends to spike faster than it falls and can take longer to come down.

Japan Rates Fx Spillovers And Carry Unwind Channel

  • The Japan–US yield differential narrowed materially during 2025, which may reduce the attractiveness of related carry and trend opportunities going forward.
  • Developments in Japan are becoming more important over time and may matter more than most market participants currently realize.
  • Japanese government bond yields experienced a sharp spike, with the 10-year JGB around 2.41%, alongside significant moves in the yen.
  • As Japanese yields rise and the Japan–US yield gap narrows, the yen-funded carry trade becomes less attractive, encouraging flows from US bonds back into Japan and pressuring US yields upward.

Institutional And Product Constraints In Diversifier Adoption

  • Some German institutions will not invest in strategies that contain commodities even when commodities would complement fixed-income-heavy portfolios.
  • Providing a stable return target such as CPI plus 4% with low equity correlation can reduce reliance on forecasting inflation regimes because allocators struggle to time strategy allocations.
  • Separating commodity trend from financial trend can improve allocator utility because commodities embed distinct physical risk factors and often require different trading treatment than fixed income.
  • Offering separate sleeves with different risk factors enables allocators to express preferences such as inflation/real-asset exposure via commodities or broader macro exposure via combined allocations.

Watchlist

  • The Japan–US yield differential narrowed materially during 2025, which may reduce the attractiveness of related carry and trend opportunities going forward.
  • Developments in Japan are becoming more important over time and may matter more than most market participants currently realize.

Unknowns

  • What is the exact empirical methodology behind the claim that a 50% bonds / 50% commodity trend portfolio delivers roughly CPI plus 4% across inflation regimes (data window, rebalance frequency, leverage, fees, and transaction costs)?
  • How is “commodity trend” implemented in the discussed framework (signal horizons, risk targeting, contract selection, roll methodology, limits in less liquid contracts)?
  • To what extent do bonds actually become equity-correlated conditional on inflation level and inflation momentum, and over what horizons?
  • What in-corpus evidence supports the characterization of current/near-term Fed stance and real-rate levels, and how sensitive are conclusions to alternative real-rate estimates?
  • What evidence supports the cited US debt and interest-cost figures, and how are they linked (mechanistically) to inflation outcomes versus other fiscal adjustments?

Investor overlay

Read-throughs

  • Energy transition plus slow mining supply response can raise the probability of persistent commodity trends and more inflation variability, which may weaken the real return role of nominal bonds.
  • Generic trend signals may be less effective in equities than in rates or FX due to differing autocorrelation properties, implying that trend outcomes can be more dependent on asset class design choices.
  • Narrowing Japan to US yield differentials can reduce yen funded carry incentives, shifting global flow dynamics and potentially changing the opportunity set for carry and related trend exposures.

What would confirm

  • Evidence that commodity total returns show sustained positive autocorrelation and that trend implementations using total return signals remain robust after accounting for roll and transaction costs.
  • Regime analysis showing bonds deliver CPI minus outcomes and higher equity correlation specifically when inflation is elevated or unstable, consistent across multiple horizons and datasets.
  • Continued Japan driven yield differential compression alongside observable signs of carry unwind dynamics and spillovers into non Japan yields and FX behavior.

What would kill

  • Commodity trend performance and diversification benefits fail after specifying implementation details, including signal horizons, contract selection, roll methodology, liquidity limits, fees, and costs.
  • Empirical results show bonds retain reliable real returns and low equity correlation even during higher inflation and inflation momentum episodes, undermining the diversification breakdown premise.
  • Japan US yield differential stabilizes or re widens without associated carry unwind behavior, and Japan related developments do not measurably affect broader rates or FX dynamics.
