What ZARFI is

One engine, from tick to committee pack.

A live desk operating model layered on a persistent knowledge base — every mark, risk number and P&L line reproducible from source, every convention codified to the SA & Namibian market standard.

Live desk OS

Daily marking, DV01/CS01 risk, P&L attribution and scenario stress — convention-correct across SA & Namibian rates.

Institutional mandates

Money-market & segregated books — MTM vs book-value shadow pricing, WAM/duration targeting and NCCF management.

Multi-asset cross-desk

SAGBs, RN & ZARONIA FRNs, JIBAR/ZARONIA swaps, R-bond futures — with cross-asset FX, equity and options context.

Auditable & reproducible

BESA v4.4 pricing, ZARONIA 5-JBD-no-shift compounding, hash-chained audit trails and signed, dated reports.

Under the hood

Convention-correct analytics, not approximations.

The mechanics the SA market actually trades on — modelled exactly, marked to the JSE close and the SARB rank-1 fixings.

ZARONIA · compounded in arrears

Daily-compounded over realised fixings, 5-JBD lookback, no observation shift.

Key-rate DV01 ladder

Rate risk decomposed by tenor bucket — R per basis point.

BESA v4.4 · clean → dirty

Settlement price = clean + accrued; accrual resets each coupon (books-close aware).

One enterprise

The South African fixed-income stack.

ZARFI sits alongside a family of specialised SA rates platforms — the institutional desk, the R-bond analytics service and the retail savings-bond club — under one house.
