Capabilities

Eight strands, one discipline.

The work below is specific and engagement-led. Each strand names the brief clients arrive with, the way we work it, and what is delivered. Where a strand sits on analytical infrastructure the firm builds and runs, that infrastructure is named — as a source, not a product.

01

RSA Retail Savings Bonds · sovereign retail bond programmes

The RSA Retail Savings Bond programme in the depth it actually runs — fixed-rate 2/3/5-year issues, inflation-linked 3/5/10-year issues, top-up mechanics, redemption windows. Full-lifecycle advisory: design, curve-aware pricing, investor-behaviour modelling, project management, and technical product oversight. Portable to other Southern African sovereigns.

Brief
We are designing, launching, re-pricing, or operating a sovereign retail savings bond programme — and want senior depth on the real product mechanics, investor behaviour, and place in the funding stack.
Approach
The RSA programme as it actually runs — 2/3/5-year fixed-rate issues, 3/5/10-year inflation-linked, top-up and redemption mechanics. Pricing is calibrated against the wholesale SAGB and ILBI curves, not against a historical print. Investor behaviour is modelled — uptake, redemption through falling-rate regimes, segment composition of demand — and the programme's role in National Treasury's funding stack is made explicit. Portable to other Southern African sovereigns.
Deliverable
Programme design document, pricing model (wholesale-curve-aware, by tenor and variant), behavioural model (uptake and redemption), performance study against SAGB and ILBI alternatives, and an implementation plan covering policy, technology, operations, and communications. Prepared at a standard suitable for central bank or National Treasury review.

02

Fixed income & rates

SAGB curve, ILBs, swap basis — read for what they say, not what they are quoted at.

Brief
The book's duration and curve exposure look wrong against where the SAGB curve actually sits. We need another view.
Approach
Bottom-up SAGB curve, with fitted nodes maintained by the firm. Relative value across bonds, swaps, and inflation-linked issues. Dislocation measured against the fitted level rather than against a dealer run. Level, slope, and curvature each separated and priced.
Deliverable
Fitted curve, relative-value sheet, and a written read on where the book is mispositioned and why.

03

JIBAR → ZARONIA transition

The mechanics of moving a book off JIBAR without writing basis into every position.

Brief
We hold FRNs, swaps, and funding legs indexed on JIBAR. We need to be ready for ZARONIA and we are not.
Approach
Instrument-level conversion mechanics — compounded ZARONIA vs term-rate equivalents, spread adjustments, convexity effects, and fallback drafting where instruments reference JIBAR specifically. Every position re-priced under both indices so the basis the client is retaining is made visible before it is committed.
Deliverable
Instrument-level transition plan, valuation delta, operational checklist, and draft amendment language where contractual change is required.

04

Treasury & balance sheet

Funding curve, liquidity laddering, and rate-sensitivity work at the level a treasurer can operate.

Brief
Our funding curve does not match our asset-side duration, and the liquidity layer needs a rework.
Approach
Asset and liability decomposition; funding-curve construction; liquidity laddering against stress and going-concern scenarios; rate sensitivity across the book; optionality in the funding stack priced explicitly rather than assumed.
Deliverable
Funding framework, rate-sensitivity model, and a sequenced plan for the balance-sheet changes that actually move the position.
05

Structured finance

Debt instruments designed from the cashflow up — credit-linked notes, geared funding, step-rate structures — where standard products do not fit.

Brief
We need a liability that fits a particular issuer and investor pair. Nothing standard works.
Approach
Risk allocation between issuer and investor specified up front. Cashflow, rating, tax, and regulatory treatment worked through together. Credit-linked notes, geared funding, and step-rate structures used where the economics support them.
Deliverable
Term sheet, cashflow model, investor memo, and issuer memo.
06

Portfolio construction & transformation

Transformation mandates broken into their underlying risks, then sequenced.

Brief
We have a transformation mandate on an existing book and need an outside view on how it actually gets done.
Approach
The brief decomposed into its underlying risks — duration, spread, curve, liquidity. Construction framework agreed in writing; liquidity laddered against the mandate's redemption terms; a sequencing plan with stop-and-re-plan triggers rather than a fixed timetable that ignores the market.
Deliverable
Construction framework, implementation sequence, and an ongoing monitoring layer through to the end of the mandate.

07

Market data & analytics

The analytical infrastructure we run for our own work, scoped to a client's portfolio.

Brief
We want the analytical view you run for your own work, applied to our positions.
Approach
Tooling already exists — the work is scoping and provisioning it. Yield curves and bond data from the firm's market-data layer; swap, FRA and IRS from the rates layer; broader fixed-income intelligence from the reference layer. Client-specific data brought into the same infrastructure so the views are consistent.
Deliverable
A provisioned analytical environment with the relevant curves, models, and dashboards, kept current while the engagement runs.

08

Implementation & tooling

Analysis built into a working tool the client's team operates day to day.

Brief
The analysis is clear. We need something we can run every day without rebuilding it each month.
Approach
Analysis built into a working tool — dashboard, pricing utility, or monitoring layer — on the same infrastructure we run internally. The client's team operates it after handover.
Deliverable
A working tool, with source code and models, running in the client's environment.

Reference calculators

Live tools the firm hosts on Streamlit, calibrated to RSA / SAGB market context. Reference material — not products, not investment advice, not binding pricing.

Calibrations to other jurisdictions are produced inside an engagement against the local sovereign curve.

  • RSA RSB — fixed-rate variant pricing

    rsarsb-fixed.streamlit.app

    Coupon and price calculation for the RSA Retail Savings Bond fixed-rate variants (2 / 3 / 5-year), with comparator reads against the wholesale SAGB curve and bank-deposit alternatives.

  • RSA RSB — top-up bond mechanics

    topupbond.streamlit.app

    Top-up mechanics for the RSA Retail Savings Bond — incremental investment into an existing holding under programme top-up rules and accrual treatment.

  • ZARONIA reference-rate tooling

    zaronia.streamlit.app

    ZARONIA term-rate construction, compounding conventions, fallback mechanics, and JIBAR → ZARONIA spread-adjustment reads.

Engagements

Each strand above runs as an engagement, not a product.
