Cash Flow Forecasting for Insurance: Claims Funds, Bordereaux Cycles, and the 45-Day Gap

Why cash flow forecasting is harder in insurance than in any other industry

Most cash flow forecasting guides assume the hard part is building a model. In insurance, the hard part is knowing what to model.

A manufacturer forecasts outflows from purchase orders. A SaaS business forecasts churn from cohort curves. Insurance companies forecast from events that have not happened yet — claims that will be filed, settled, and disbursed months or years after the policy was written. The cash leaving the business is determined by loss experience, not by scheduled commitments.

That asymmetry — predictable inflows, stochastic outflows — defines how carriers hold reserves, how MGAs manage delegated authority funds, and how TPAs maintain claims account balances. Any forecasting approach that ignores it will consistently underprepare.

This article covers the mechanics of cash flow forecasting specific to insurance operations: premium float, claims fund requirements, delegated authority reconciliation, and why the 45-day bordereaux gap is the single most important liquidity variable most finance teams are not modelling correctly.

The bordereaux cycle gap: the core forecasting problem for delegated authority

Delegated authority structures create a specific forecasting challenge that standard treasury models do not handle.

An MGA writing on behalf of a Lloyd's syndicate or a carrier holds claims funds in trust accounts. Those funds are not the MGA's money — they belong to the capacity provider and are governed by the delegated authority agreement. The MGA can only draw on them for valid claims payments, must reconcile them against bordereaux, and must maintain minimum balances as specified in the agreement.

The forecasting question for an MGA treasury team is not "how much cash will we have?" — it is whether there will be enough in the trust account to meet claim payments due this week, while maintaining the required float balance, before the next bordereaux settlement arrives.

The gap between Day 1 and Day 45–60 is the window the MGA must fund from its own trust account balance. Under normal conditions, the balance is sufficient. After a large loss event — a weather cluster, a commercial claims spike — the balance can be drawn down to the minimum required threshold before replenishment arrives. At that point, the MGA cannot pay new claims. That is an operational failure and a regulatory event under FCA CASS 5 client money rules and equivalent frameworks.

Lloyd's has published detailed Claims Bordereaux Standard Operating Procedures defining exactly how coverholders must report claims activity to syndicates via the Delegated Data Manager platform. The cadence and format requirements create the structure — but not the forecasting tools to manage liquidity within it.

US regulatory context: what MGAs are required to hold

In the United States, the NAIC Managing General Agents Act (Model #225) sets the baseline for MGA cash handling. Key requirements relevant to cash flow forecasting:

• Collected funds must be held in FDIC-insured fiduciary accounts, separate from operating cash
• Remittance to the insurer must occur at least monthly
• Retained claims funds must not exceed three months of estimated claims payments

The "three months of estimated claims payments" limit is itself a forecasting obligation. An MGA that cannot accurately estimate its 90-day claims outflow cannot reliably demonstrate regulatory compliance with the retention limit.

The NAIC Unfair Claims Settlement Practices Act (Model #900) adds another layer: most US states require claims to be acknowledged within 10 days, investigated and accepted or denied within 30 days, and paid within a further fixed period after acceptance. These timelines are the regulatory floor for claims settlement velocity — and directly define the minimum payment frequency that a cash flow forecast must plan for.

Multi-currency complexity in Lloyd's and international structures

Lloyd's syndicates, internationally operating carriers, and MGAs with cross-border books face an additional dimension: currency.

A syndicate writing US property, European liability, and Asian marine may receive premiums in USD and EUR but pay claims in the policyholder's local currency. The float is not just a timing mismatch — it is a currency mismatch. Unhedged FX exposure on claims reserves can materially affect the base currency cash position.

EIOPA's 2025 final report on Liquidity Risk Management Plans under the Solvency II review requires insurers to maintain formal short, medium, and long-term cash flow projections across assets and liabilities — including stress scenarios. Multi-currency cash flow is specifically addressed as a risk dimension requiring explicit modelling.

The standard corporate treasury model — consolidate everything into a base currency, manage FX centrally — does not work when claims need to be paid in the policyholder's local currency within 24 hours of settlement approval. Speed of payment is a service standard. It cannot be sacrificed to treasury efficiency.

Why generic treasury tools fail in insurance

Tools like Trovata, Kyriba, or standard ERP treasury modules are built for corporate treasury management: consolidating bank accounts, sweeping cash, managing revolving credit facilities, forecasting operating cash flow from AR/AP data. They were not built for insurance's structural requirements.

The result: insurance finance teams typically run two systems in parallel — the generic treasury tool for operating cash, and a combination of spreadsheets and claims management reports for claims fund management. The two do not reconcile cleanly. Neither gives a complete picture. And the spreadsheets are only as current as the last manual update.

Building a claims cash flow forecast: the four-layer framework

For a finance team starting from scratch, the forecasting model builds in four layers. Each layer narrows the uncertainty — and each depends on the quality of the one beneath it.

The gap between Layer 3 (outflows) and Layer 4 (inflows) at any point in the 90-day window is the liquidity requirement to plan for. A negative gap signals action: draw down a credit facility, request early bordereaux settlement, or initiate an inter-entity transfer — before the shortfall materialises, not after.

What good cash flow forecasting infrastructure looks like

For an insurance carrier or MGA to forecast claims cash flow with confidence, the infrastructure needs to do four things.

1. Real-time claims fund visibility

Account balances need to be current, not T+1. A claim approved at 4pm on a Friday that triggers a payment on Monday morning needs to be reflected in the Friday afternoon balance — not discovered on Monday when the account shows insufficient funds. This requires direct API connections between the claims management system and the treasury system, not a daily file export.

2. Payment obligation pipeline

The forecast needs to know not just the current balance but the committed outflows: claims approved for payment, reserve movements that will trigger disbursements, and scheduled instalment payments on settled claims. This pipeline, combined with the incoming replenishment schedule (bordereaux settlements, quota share recoveries), gives the treasury team a rolling net position view across a 0–90 day horizon.

3. Automated bordereaux reconciliation

Every payment from a trust account should automatically match against the corresponding claim record, update the bordereaux position, and flag any breaks immediately. The Institute and Faculty of Actuaries' work on Solvency II technical provisions for general insurers highlights that cash flow forecast quality depends directly on underlying claims data quality — and manual reconciliation processes are the single largest source of degradation.

4. Multi-entity, multi-currency consolidation

A group running multiple syndicates, MGAs, or country operations needs to see the consolidated picture and the individual entity picture simultaneously. Cash trapped in one entity's trust account cannot solve another entity's liquidity gap without a formal inter-entity transfer — which needs to be planned, not discovered as an emergency.

Insurance-specific treasury metrics

Standard corporate treasury metrics — days cash on hand, operating cash flow ratio — do not translate to insurance. The relevant indicators:

The Casualty Actuarial Society's work on stochastic claims reserving provides the actuarial foundation for modelling loss liability cash flows probabilistically — the methodology underpinning any credible long-tail claims outflow forecast.

The payment infrastructure layer

Accurate forecasting does not help if the payment infrastructure cannot execute on it.

A carrier that can forecast exactly when a large loss event will require substantial claims payments in the next five business days needs the ability to move funds, initiate payments across multiple jurisdictions, and settle quickly. If the payment infrastructure requires three to five business days to initiate an international wire, forecast accuracy is irrelevant — the operational response cannot keep up.

This is where payment infrastructure and treasury forecasting intersect. The forecast tells you what is coming. The payment infrastructure determines whether you can respond in time.

For carriers and MGAs managing claims payments at scale:

• Same-day or next-day payment to claimants globally, regardless of currency
• Pre-funded local currency accounts in key markets, eliminating correspondent banking delays
• Automated payment initiation from claims system approval, removing manual treasury steps
• Real-time settlement confirmation feeding back into the forecasting model when payments clear

Vitesse operates payment infrastructure purpose-built for this environment. We hold funds in local currency accounts across more than 100 countries, so insurance carriers and MGAs can settle claims without the correspondent banking chain. When a claim is approved, funds move directly from the trust account to the claimant without the multi-day lag of an international wire — and the payment confirmation feeds back into the treasury model in real time.

For MGAs managing delegated authority funds, Vitesse provides a dedicated claims fund account structure that sits between the capacity provider's replenishment and the individual claim payments — maintaining the trust account discipline required by the delegated authority agreement, with automated reconciliation against the bordereaux.

Key takeaways

• Insurance cash flow is structurally different from corporate cash flow: inflows are scheduled, outflows are stochastic and event-driven
• For MGAs and TPAs under delegated authority, the bordereaux replenishment cycle creates a structural float gap — typically 45–60 days — that must be sized and managed proactively
• US regulatory requirements under NAIC Model #225 make accurate 90-day claims forecasting a compliance obligation, not just a treasury preference
• Generic treasury tools were not built for trust accounts, bordereaux reconciliation, or stochastic claims outflows
• EIOPA Solvency II revisions are tightening formal liquidity risk management plan requirements across European carriers and Lloyd's syndicates
• Payment infrastructure speed directly affects treasury planning: faster settlement compresses the float gap and improves forecast accuracy
• The foundation of any insurance cash flow forecast is real-time account visibility — if the current position is wrong, every projection built on it is wrong
