Government & supranational bonds
Mechanics
The highest-rated (typically AAA/AA), most liquid instruments in the market. With little or no credit spread, their price is driven almost entirely by interest rates: they are pure duration, and the natural home of a portfolio’s defensive liquidity.
Where we add value
We treat government bonds as the portfolio’s primary instrument of duration and liquidity management: positioning along the curve and across markets, managing duration deliberately, and holding the liquidity reserve that allows the rest of the portfolio to act when spreads dislocate.
Investment-grade corporate credit
Mechanics
Bonds rated BBB-/Baa3 or better, issued by companies whose prompt payment is judged relatively secure. Typically senior unsecured claims; returns combine the rate component with a moderate credit spread, and prices respond to both.
Where we add value
The index owns the largest borrowers by construction; we underwrite issuer by issuer instead, avoid balance sheets we would not lend to at any spread, apply discipline in new issues, and rotate along curves and sectors where relative value is genuine rather than merely apparent.
Inflation-linked bonds
Mechanics
Bonds whose principal and coupons are indexed to inflation: the yield is a real yield, and the return depends on realised inflation relative to what the market had priced. They are the one instrument whose payments rise with the price level itself.
Where we add value
We hold inflation-linked bonds when breakeven rates underprice the inflation outcomes we consider plausible, and size them as real duration within the protection allocation: a hedge for the scenario that most damages conventional bonds.
Money market & floating-rate instruments
Mechanics
Treasury bills, commercial paper and floating-rate notes: instruments with little or no duration, whose coupons reset with short-term rates. They are where a portfolio holds its liquidity and, when curves are flat or inverted, where it can be compensated while waiting.
Where we add value
We treat cash and floating-rate instruments as an active position rather than a residual: the reserve that funds action when spreads dislocate, earning carry without surrendering the option to move.
High-yield bonds
Mechanics
Issuers rated BB+/Ba1 or below pay materially higher coupons to compensate for default risk. Maturities tend to be shorter, so rate sensitivity is lower: returns are driven mainly by credit, and behave more like the economy than like rates. Many issues are senior secured, which historically supports better recoveries than unsecured paper.
Where we add value
This is a market that rewards selection by issuer rather than exposure by category. We take exposure only where the spread clearly compensates the risk, avoid crowded structures, and act when rating downgrades force index-bound holders to sell sound businesses at depressed prices.
Convertible bonds
Mechanics
Corporate bonds with an embedded right to convert into the issuer’s shares at preset terms. The bond provides a floor; the conversion right adds equity optionality, so the instrument is naturally asymmetric: sensitive to equity prices and their volatility as well as to credit.
Where we add value
Convertibles are a means of acquiring convexity, and convexity has a price. We hold them when the option is undervalued relative to the credit, sizing positions so the asymmetry works for the portfolio rather than adding unintended equity exposure.
Preferred shares & subordinated / hybrid debt
Mechanics
Instruments deeper in the capital structure: behind senior creditors, ahead of (or alongside) equity. They pay higher, often fixed coupons in exchange for lower recovery if the issuer fails, and typically carry structural features that matter: call schedules, coupon resets, discretionary payments.
Where we add value
Here the analysis is structure by structure, not only issuer by issuer. We lend deep in the capital structure only to businesses whose senior debt we would also own, and we price every call and reset feature before committing capital.
Zero-coupon bonds
Mechanics
No periodic interest: bought at a discount, repaid at par, with the return locked into that gap. With no coupons to reinvest, they carry the longest duration per unit of maturity; small yield moves produce large price moves.
Where we add value
We use zero-coupon bonds as a precision tool: the most capital-efficient way to hold duration and convexity in the protection allocation, where their sensitivity to falling yields is most effective.
Covered & secured bonds
Mechanics
Claims backed twice over: by the issuer and by a ring-fenced pool of assets that remains available to bondholders if the issuer fails. The result is a defensive instrument with tight spreads and strong regulatory frameworks in most European jurisdictions.
Where we add value
The work is in the collateral and the framework: we analyse the quality of the pool and the strength of the legal regime, jurisdiction by jurisdiction, and hold covered paper where it genuinely adds protection per unit of yield foregone.
Rates & credit derivatives (overlay)
Mechanics
Futures, swaps and options do not add a new asset class: they reshape the ones we own, adjusting duration without selling bonds, hedging unwanted currency or credit exposure, and providing the convexity that cash instruments cannot deliver efficiently.
Where we add value
Derivatives are central to our all-weather discipline. We use them to keep the portfolio asymmetric, protected against the moves that hurt and exposed to the ones that reward, with counterparty and basis risk managed as deliberately as the positions themselves.
