FX Module

It's 3 AM in Praia. A payment of EUR 50,000 needs to land in a CVE account before market open. The rate has to be fair, the spread profitable, and the hedge in place before the transfer executes. That's what the FX Module handles — silently, every time, across every payment that crosses a currency boundary.

The FX Module is the currency conversion backbone of the Paymart Suite. Every cross-currency payment, multi-currency account conversion, and international transfer depends on it. For institutions operating between EUR and CVE — and increasingly USD and West African XOF — managing FX exposure is a core business concern. Not an afterthought. The module pulls live rate feeds from ECB and commercial providers, applies adjustable markups per currency pair and client tier, and executes rules-based hedging strategies that protect the institution's position while still offering competitive rates to customers.

This balance matters. Too tight a spread and you lose money on every conversion. Too wide and customers leave for competitors. The FX Module lets you set different spreads for different corridors, different client tiers, different volumes — and adjust them in minutes when the market moves.

The module supports 50+ currency pairs with live, daily, and weekly rate windows. Historical rate storage enables back-office analysis and regulatory reporting. Rate movement alerts notify treasury teams when currencies cross defined thresholds, enabling proactive position management rather than reactive loss mitigation.

In our experience, banks operating in the Europe-Africa corridor underestimate how much revenue they leave on the table with fixed daily rates. Live feeds alone can recover 1-2% of spread revenue that competitors capture.

The FX Module operates across three layers: rate acquisition, conversion execution, and risk management. Each layer is adjustable independently.

Rate acquisition pulls from ECB reference rates and commercial providers including Reuters and Bloomberg. Multiple feed sources with automatic fallback ensure rate availability even when a primary provider goes down. Rates are applied across all platform modules — payments, accounts, cards — so a customer sees the same EUR-CVE rate whether they're sending a transfer, converting within their account, or loading a card.

Conversion execution triggers when a payment currency differs from the source account currency. The system handles 50+ currency pairs with full rate transparency and customer disclosure. For batch operations — payroll, merchant settlement, mass payments — a single bulk rate applies to all transactions, ensuring fair and consistent pricing.

Risk management runs in parallel. When net open position exceeds defined thresholds, the system either executes hedging trades automatically via the FIX-connected ECN or alerts the treasury team for manual intervention. Live exposure dashboards show net open positions, unrealized gains/losses, and Value-at-Risk across all currency pairs.

Beyond these three layers, the module provides:

• Corridor-specific rates — Custom pricing for Europe-to-Cabo Verde and Cabo Verde-to-West-Africa corridors, reflecting the competitive dynamics and cost structures of each route
• Rate window management — Live, daily, or weekly rates per currency pair and product type. Daily rates for standard transfers; live rates for instant payments and high-value corporate transactions
• Markup layers — Flexible markups on top of base rates, expressed as fixed pips, percentage, or combined, applied transparently in customer-facing quotations
• Historical rate storage — Full database for audit, compliance, mark-to-market calculations, and customer dispute resolution with verifiable evidence for any past transaction date
• Audit trail — Every FX transaction logs the rate applied, source rate, markup, timestamp, and approver

Every cross-currency transaction generates spread revenue. In the Europe-Africa corridor, where most payments involve at least one currency conversion, FX becomes a significant, recurring revenue stream — without additional operational effort.

But revenue is only half the equation. Rules-based hedging protects the institution from adverse currency movements that can erase payment processing margins in hours. Institutions with manual treasury operations know this pain: a single bad quarter of unhedged EUR-USD exposure can wipe out a year of payment processing profit.

Granular spread controls let you compete where it matters. Offer near-mid-market rates on high-volume corridors to win market share. Maintain wider margins on less competitive routes. The flexibility is the point — you're not locked into one pricing model.

The operational gains compound. Rate feeds eliminate manual entry errors. Hedging reduces the need for constant treasury monitoring. Together, these efficiencies cut FX operations staffing requirements by roughly 50%, freeing treasury professionals for strategic decisions rather than rate-watching.

The FX Module connects to external systems through standard financial protocols. FIX 4.4 support enables electronic communication with FX trading venues and liquidity providers for hedging execution and direct market access. WebSocket-based rate streaming delivers tick-by-tick updates to trading interfaces and customer-facing displays. A full REST API with OpenAPI 3.0 specifications handles rate queries, conversion requests, position reporting, and hedging instructions.
