A pension scheme can have enough assets to cover its measured promises and still struggle to deliver cash on Tuesday. The funding position describes a balance sheet. A collateral call brings a deadline.
Four years after the autumn 2022 gilt-market disruption, that distinction remains useful when judging claims about pension resilience. Stronger funding does not answer every liquidity question. Equally, a request for cash does not establish that pension promises are underfunded.
The practical issue is narrower. Which assets can meet the demand, who can release them, and will they arrive in time? That is where a reassuring total can conceal a dependency.
Fact: what the 2022 episode exposed
Liability-driven investment, or LDI, helps defined benefit pension schemes manage exposure to changes in the value of their future payment obligations. Leveraged arrangements use financial instruments to obtain exposure beyond the cash initially committed. That creates collateral requirements.
The FCA’s April 2023 account of the disruption records a rise of 160 basis points in the 30-year nominal gilt yield over four days in September 2022. A basis point is one hundredth of a percentage point: 160 basis points means 1.60 percentage points. The FCA identified weaknesses in risk management, communications and operations, alongside the market shock.
Higher yields reduced the prices of long-dated gilts. The Bank of England’s March 2023 explainer describes how collateral demands and unsuccessful recapitalisation led some LDI funds to sell gilts into an illiquid market. Those sales could deepen the price falls and generate further demands.
This is a mechanism with several links. A yield move changes exposures. A counterparty requires collateral. The fund needs eligible assets. Its pension-scheme investors need to supply them. If that chain breaks, selling becomes harder to avoid.
Interpretation: funding and liquidity answer different questions
Consider the distinction in a deliberately simplified setting. A pension promise due in twenty years has a value today. The calculation discounts that future payment using an assumed rate. If that rate rises, the present value falls, all else equal.
Assets can fall in value at the same time. The change in the funding ratio depends on both sides of the balance sheet, their sensitivities and the valuation method. A better ratio is therefore possible alongside an immediate need to supply collateral. It is not guaranteed by a rise in yields.
A funding ratio cannot reveal how quickly assets become spendable. A property holding, an investment with a notice period and cash already in an accessible account can all count towards assets. They have different usefulness when a payment deadline is near.
The same applies to location. An asset held by the scheme is not necessarily already available to its LDI manager. Instructions, permissions and settlement sit between ownership and delivery. The reader needs evidence about those steps before treating aggregate wealth as available liquidity.
Fact: the buffer is designed to buy time
The Pensions Regulator’s guidance, published on 24 April 2023 and checked for this article on 12 October 2026, distinguishes an operational buffer from an additional market-stress buffer. It describes a minimum stress buffer of 250 basis points, assuming replenishment within five days. The operational component comes on top.
That figure measures resilience to a yield shock. It is not a 2.5% cash holding, a maximum permitted yield, or a prediction of the next market move.
The Bank’s explainer also says one regulatory standard cannot cover every risk. Exposure structure and the pattern of yield changes matter. A single headline threshold therefore needs context before it becomes evidence of resilience.
Interpretation: headroom needs a route back
A buffer postpones the moment when new collateral must arrive. It cannot, by itself, establish that replenishment will work. The useful test is a sequence, rather than a large number displayed without conditions.
First comes the trigger. A manager may request additional assets before the buffer is exhausted. A call at that stage can be evidence that a protective process is functioning. Describing every call as distress would erase that distinction.
Then comes the source. Cash already available has fewer conversion steps than an asset requiring a sale. A borrowing arrangement introduces another dependence: the lender must be willing and able to provide funds on the agreed terms.
Finally comes delivery. An instruction sent is different from a transaction completed. A scheme may identify adequate assets yet miss the deadline because authority is unclear or settlement takes longer than expected. Operational evidence belongs beside the financial evidence.
Find the dependency. In this case it may be the person authorised to instruct a transfer, rather than the size of the pension scheme.
Speculation: a fictional cash call with two outcomes
Suppose a fictional scheme has £1 billion of assets and measured liabilities of £900 million. Its funding ratio is approximately 111.1%: £1 billion divided by £900 million. Those invented figures establish neither a real scheme’s condition nor its liquidity requirement.
Now assume its LDI arrangement requests £20 million of additional collateral, due within five working days. The scheme has £8 million of immediately accessible cash. It must find a further £12 million.
In the first scenario, an authorised sale settles in time and the proceeds reach the manager before the deadline. The collateral request is met. The initial cash shortfall has been resolved without establishing a failure of the scheme’s pension promises.
In the second scenario, the same £12 million is expected from an investment that cannot settle before the deadline. The scheme remains asset-rich in this simplified balance sheet, but that route cannot meet this particular demand. Another eligible source would be needed.
These are timing scenarios, not a model of a market crash. They assume no transaction costs, taxes, price changes or other cash demands. They do not calculate the collateral effect of any particular yield move. Their purpose is to isolate a constraint: assets available eventually are different from assets available by the required date.
Interpretation: evidence of resilience deserves equal weight
It would be misleading to stop at the failed-transfer scenario. A documented, tested transfer process changes the assessment. So does evidence that a manager can access eligible collateral without waiting for a fresh decision each time.
Reducing exposure can also reduce a future collateral demand, although it may change how closely assets match liabilities. The choice involves trade-offs. An editorial account should describe those trade-offs rather than assume that the smallest exposure is automatically the best pension strategy.
A completed replenishment provides stronger evidence than a statement that assets could be sold. Repeated successful calls can show that a process works under the conditions experienced. They cannot demonstrate that every larger or faster shock would be manageable.
Who could benefit?
Fact: The deadline creates work for businesses that manage pension assets. Legal & General Group (LSE: LGEN) describes both liquidity funds and pooled or bespoke defined benefit solutions with derivative overlays in its 2025 solvency report. BlackRock (NYSE: BLK) offers a UK LDI platform. The Bank of New York Mellon Corporation (NYSE: BNY) has a connection through Insight Investment: its subsidiary announced a £1 billion UK pension mandate on 10 September 2026, covering liability-hedging assets, contractual income strategies and investment oversight.
Interpretation: Over several quarters, these providers could gain or retain fee-paying mandates if trustees pay for better-integrated hedging, cash management and governance. The condition is delivery: a service must help assets reach the right place in time, at a cost the client accepts. More collateral held by a scheme is not automatically more revenue for its manager. The Insight mandate is an asset-management amount, not £1 billion of sales.
The group-level effect remains uncertain. These are diversified businesses, and the cited disclosures do not isolate incremental profit from faster collateral replenishment. Mandate retention, net flows, fees and servicing costs would be more useful evidence than a broad claim that pension resilience produces winners.
Who’s at risk?
Fact: The FCA’s April 2023 guidance expects LDI managers to test operational arrangements and help clients deliver collateral within five days or sooner; where that cannot happen, it expects other liquidity measures to increase. This is a sector expectation, not a finding that any of these named providers currently breaches it.
Interpretation: Legal & General, BlackRock and BNY face the other side of the service opportunity. If transfers fail during a shock, clients may question the arrangement and managers may need additional operational resources. The immediate pressure can arrive over days. Any effect on retained mandates, costs and profitability would emerge over subsequent quarters and would depend on contracts and the firm’s response.
BlackRock’s 2025 annual report says advisory and administration fees are primarily based on agreed percentages of assets under management. That supplies a separate business constraint: retaining a mandate does not insulate fee income from changes in its asset base. It does not quantify a UK pension-liquidity shock’s effect.
Speculation: A faster, larger shock could expose transfer dependencies that ordinary calls have not tested. Evidence of completed replenishment and retained hedges would weaken that concern; delayed delivery would strengthen it. Client collateral is not the same as the listed parent’s debt. Neither this scenario nor the service opportunity predicts a share-price move.
What this evidence cannot establish
This article examines published regulatory explanations and a fictional illustration. It does not inspect any individual scheme’s holdings, current funding valuation, collateral terms or transfer records. It cannot rank schemes or establish that the sector would withstand a repeat of 2022.
The guidance dates are explicit because this is an explanatory analysis, not a report of a new regulatory announcement. A prescribed buffer is a design requirement. It is not proof that every arrangement meets it today.
The next evidence that would change a specific assessment is concrete: accessible collateral, a tested delivery timetable, completed recapitalisation and disclosed exposure after the event. Evidence of delayed transfers or competing demands on the same assets would point the other way.
A stronger funding position matters. So does the ability to supply the right asset before the deadline. Resilience requires an account of both.
