Case Studies

Illustrated case studies of real institutional failure modes.
How capital leaks, hedges drift, liquidity gets trapped, and governance breaks under real-world constraints.

These are not hypothetical scenarios.

They are recurring structural failures observed across private credit, project finance, infrastructure, family offices, and lean asset managers.

Each case study shows:

The original intent
Where the structure quietly broke
Why the issue was missed
How capital, flexibility, or credibility was lost
What needed to change to stop the bleed

No theory. No generic advice.
Only the mechanics of failure in live portfolios.

Built from execution, not hindsight.

These case studies are informed by direct responsibility for:

Hedge construction and re-design
Pricing and execution under live market conditions
Collateral and liquidity management
Governance, IC, and regulatory constraints
Trade-offs between risk optics and economic reality

Decisions are made under conditions where:

Time is limited
Documentation is imperfect
Markets move
Nobody wants surprises in front of IC or LPs

The same execution-first mindset underpins Para Bellum Advisors’ work with lean investment teams.

Recognisable Failure Modes

Strategic intent. Structural drift. Real consequences.

These case studies illustrate how structural portfolio failures are identified and corrected under real-world constraints..

Portfolio-Level Interest Rate Hedge Consolidation

Portfolio-Level Interest Rate Hedge Consolidation When asset-level hedges quietly become a portfolio constraint.

Infrastructure platforms rarely fail because they are unhedged. They lose flexibility when independently “safe” hedges accumulate into a fragmented system that dictates liquidity, refinancing, and capital decisions.

Counterparty Credit Risk Reduction – Infrastructure Portfolio

Counterparty credit risk in infrastructure portfolios rarely appears as immediate loss.

It emerges as forced liquidity action driven by legacy CSAs, downgrade triggers, and concentrated derivative exposure.

This case shows how derivative book rationalisation restores control before credit stress turns into a decision clock.

Rebuilding Capital Efficiency in an Operating Airport Financing Stack

A regional airport financing stack suffered capital inefficiency not because hedges failed, but because CSA and collateral mechanics trapped liquidity under rising rates.

Asset performance remained stable, yet deployable capital collapsed. The failure was documentation-driven capital behaviour, not market stress or credit deterioration.

Inflation Hedge Gap in Regulated Utilities

Inflation risk in regulated utilities rarely shows up as volatility.

It appears as deferred value extraction created by regulatory lag and ungoverned real-rate exposure.

Contingent FX Hedging for Cross-Border Infrastructure Acquisitions

Cross-border infrastructure acquisitions often fail at the execution stage.

FX exposure peaks when deal certainty is lowest. Conventional hedging tools force investors to choose between bid credibility and break-risk discipline.

See how Contingent FX structures restore control by aligning hedge commitment with transaction certainty – without embedding losses on deals that never close.

Callable Debt & Swap Coordination

When refinancing flexibility exists but cannot be exercised safely.

Callable debt often appears to preserve optionality. In practice, swap termination mechanics can turn refinancing into a forced, high-risk decision.

The risk is not rates. It is reaching the call window without structural control.

Hedging Illiquid Private Credit When You Can’t Exit

When illiquidity quietly turns credit exposure into a governance problem.

Private credit portfolios rarely fail because loans default all at once.
They fail when losses cluster under illiquidity, marks lag reality, and decision-makers lose confidence at precisely the wrong moment.

The issue is not credit quality. It is whether downside can be paced, explained, and governed when action is no longer possible.

Synthetic Exposure Without Mandate Breach

In mandate-constrained defensive portfolios, return drag often comes from structure, not risk.

This case shows how legally compliant synthetic exposure restored carry without breaching classification, optics, or trustee defensibility.

The cost of inaction wasn’t volatility. It would have been years of silent under-earning.

Derivatives Portfolio Review

When a derivatives programme scales faster than its control architecture.

A scaled UCITS derivatives programme where trading performance held, but control architecture lagged.

A Derivatives Portfolio Review revealed structural operational risk before audit or regulatory escalation forced action.

ISDA Negotiation and Margin Optimisation

A scaled UCITS macro fund continued operating under start-up ISDA and CSA terms long after trading volumes, counterparties, and margin flows became institutional.

The strategy performed. The collateral framework did not.

Excess margin posting, asymmetric thresholds, and idle cash buffers quietly compounded capital drag – reducing returns without triggering any operational or market alarm.

When FX Hedging Quietly Destroys Long-Term Returns

A multi-generational equity portfolio continued to apply a full FX hedge long after the economics stopped making sense.

Negative carry, roll leakage, and governance inertia quietly eroded returns – without improving portfolio resilience.

What happens when FX overlays fail silently, and how to restore control without introducing tactical FX risk.

Concentrated Equity Downside Protection

A concentrated equity position remained unprotected while selling was constrained by optics, tax, and timing.

When volatility rises, the risk is not price movement – it is having no viable options when action is required.

When Credit Index Hedges Stop Protecting the Portfolio

An index hedge remained in place while an actively managed credit portfolio evolved.

Issuer rotation and sector drift quietly eroded protection relevance, turning intended downside insurance into negative carry.

This case shows how static hedges fail dynamic portfolios – and why hedge presence is not the same as hedge effectiveness.

When Protective Put Overlays Quietly Overpay at Expiry

A systematic protective put overlay that works in drawdowns but quietly overpays at every roll.

Expiry-window execution routines embed repeatable, avoidable drag – not through bad trades, but through ungoverned operating design.

Equity Swap Financing Optimisation – TRS Spread Creep

A mature multi-prime TRS financing structure remained operationally sound while financing spreads quietly drifted off-market.

No stress event occurred. No counterparty failed.

Return drag emerged through weak pricing governance, fragmented wallet share, and the loss of credible switching leverage.

ESG-Linked Hedge Optimisation – Operating Project Debt

ESG-linked pricing improves debt economics, but legacy interest-rate hedges often remain static.

The result is quiet basis leakage, accounting strain, and uncaptured value – despite assets being “fully hedged” and ESG targets being met.

This is not a pricing or execution issue. It is a structural misalignment between ESG-linked debt economics and hedge design.

Refinancing Derivatives Transition – Operating Asset Debt

Refinancing project debt often destroys value not because the asset or debt is mispriced, but because derivatives are treated as an execution afterthought.

This scenario shows how embedded hedge value is lost through poor sequencing, ownership misalignment, and time pressure – despite stable operating performance.

Commodity Hedge Collateral Drag

Commodity hedges are meant to stabilise cashflows.

In operating-phase project finance, they often destabilise liquidity instead.

This case study examines how standard cash-margined commodity hedges quietly transform protection into leverage – draining liquidity without any deterioration in asset performance – and why treating the issue as a pricing or execution problem consistently destroys value.

Cross-Currency Carry Leakage

Operating-phase cross-currency hedges rarely fail loudly.

Instead, they leak.

What began as attractively priced offshore funding slowly turns into structurally expensive domestic debt – not because FX moved, but because carry, basis, and liquidity mechanics were never designed to evolve.

The asset performs. The hedge remains in place. Yet funding costs drift, flexibility erodes, and optionality disappears.

This is not a hedging failure. It is a synthetic funding problem hiding inside a “fully hedged” structure.

Floating-Rate Basis Risk – Operating Project Debt

When a minor amendment turns fixed-rate protection into interest leakage.

Operating assets can perform exactly as modelled – and still bleed cash through the capital structure.
When debt benchmarks change but legacy hedges don’t, “fully hedged” positions quietly become structurally floating.

The result isn’t market loss. It’s slow, persistent leakage that erodes confidence, accounting clarity, and optionality.

When Lifecycle FX Structuring Destroys Value

When adding structure increases risk instead of reducing it.

Not all FX exposure should be structured. In fast-moving distressed credit strategies, short-duration FX risk can be extinguished by speed, not hedging.

This case shows why the correct decision was to not deploy lifecycle FX structuring – and how structure, if misapplied, destroys value.

Commitment FX Drift – Derivative Portfolio Review

When FX risk becomes real before anyone owns it.

In local-currency private credit, pricing often becomes binding weeks before funding certainty exists. FX exposure is economically live at commitment – yet remains operationally unowned until closing.

The result isn’t bad execution or unlucky markets. It’s systematic USD entry drift, quietly eroding returns and underwriting discipline deal after deal.

Structuring FX Ownership into Local-Currency

When local-currency pricing quietly rewrites USD entry economics.

In local-currency private credit, FX risk becomes real at commitment – not funding. As deals sit between pricing and close, USD economics float while underwriting assumptions remain fixed.

The result isn’t a bad FX call. It’s silent return erosion caused by an unowned exposure window.

Warehouse Facility Rate Mismatch – Originator

When floating funding quietly turns growth into survival mode.

In warehouse-funded private credit platforms, assets can perform exactly as expected while margins collapse.
As funding costs reprice instantly and asset yields lag, short-duration exposure behaves like leveraged rate risk.

The result isn’t credit loss. It’s compressed ROE, covenant pressure, and forced action at precisely the wrong time.

Credit Hedge Rebuild After Index Dislocation

When protection responds to markets your portfolio never touches.

Private credit portfolios evolve. Index hedges often don’t. As underwriting becomes more specialised, public credit proxies quietly lose relevance.

The result isn’t no protection – it’s expensive protection that moves for the wrong reasons.

Covenant Breach from Hedge Ratio Drift

When amortisation quietly turns protection into default risk.

In infrastructure-style private credit, assets can perform exactly as modelled – and covenants still fail. As loans amortise and static hedges drift out of alignment, “conservative” protection quietly becomes a compliance trigger.

The result isn’t credit loss. It’s trapped liquidity, lost optionality, and forced action at precisely the wrong time.

Hedging Construction – Phase FX Exposure

When timing uncertainty quietly turns protection into liquidity stress

In project-financed renewables, FX risk is often declared “hedged” at financial close. But when construction timelines move and hedges stay fixed, protection starts behaving like a funding risk.

The result isn’t FX loss.
It’s collateral volatility, trapped liquidity, and forced decisions at precisely the wrong time.

Distressed NPL FX Lifecycle Risk

When FX quietly erodes recoveries after the hard work is done.

In distressed private credit, FX rarely causes the default – but it often determines the outcome. As enforcement and restructurings shift cashflows across currencies, unmanaged FX exposure quietly leaks value.

The result isn’t a bad recovery.
It’s distorted IRR, misattributed performance, and capital lost after the decision was already made.

If one or more of these case studies feels uncomfortably familiar, it is usually not coincidence.
The same failure modes repeat across portfolios that look very different on the surface.
