Every bond, coupon, and rating in a single view.
Fixed income positions flow in through direct custodial feeds, whether held directly or through funds, across custodians, currencies, and jurisdictions. Masttro consolidates them into one book and reports duration, yield, and credit rating for every holding. Coupons and maturities are tracked automatically, so the family knows what income is coming and when.

“Masttro quickly turned out to be much more than a technology vendor... Their business model makes them a true technological partner that supports us proactively in our growth strategy, and in turn has differentiated our value proposition tremendously.”
Maurizio Cereda, Financial Advisor
Key features
Fixed Income Reporting
Accrued interest, coupon schedules, and credit ratings fall behind when fixed income is tracked by hand. Masttro updates them as data arrives from custodians, across sovereign and corporate bonds, munis, and structured credit. Every security is reported by duration, yield to maturity, and credit rating, with security-level detail and a tear sheet for each holding. The book stays accurate all year, so year-end doesn't come with surprises.
Exhaustive coverage of fixed income types: sovereign, corporate, municipal, and structured credit, held directly or through funds
Security-level capture of coupon, maturity, frequency, and rating with accrued-interest tracking
Duration, yield-to-maturity, current yield, and average rating calculated across the whole book
Direct custodian feeds keep prices, marks, and accruals current across currencies
Holdings shown with and without accrued interest, reconciled to every custodian statement
Comprehensive tear sheets for every individual security
Every fixed income instrument, in one interactive view
Individual bonds and bond funds sit beside equities, alternatives, real estate, and cash, whether held directly or through the entities that own them, all in one connected view and in every currency.
Each holding is tied to the entity that owns it, so the family sees fixed income in the context of the whole estate.


Allocations, yield, and duration at a glance
A one-page executive summary covers the whole fixed income book, showing each top holding's market value and share of fixed income and total assets. Portfolio KPIs include yield to maturity, current yield, average duration, and average rating.
Configurable charts break the book down by coupon type, sector, duration, and rating, showing where risk and income are concentrated.
The whole book, visualized
The analysis report turns the fixed income portfolio into clear, comparable charts covering duration, sector, rating, and geographic exposure.
A principal can read concentration and credit risk at a glance, and the investment team can walk through the positioning in any meeting.


Every position, in one statement
The statement presents the fixed income book security by security, with each holding's coupon, maturity, market value, P&L, and rating.
Values are shown with and without accrued interest and reconciled against direct custodian records, so the team can close each period without chasing discrepancies.
The complete record for a single security
The tear sheet brings a bond's security details, including coupon, payment frequency, maturity, and rating, together with duration and rating analysis.
The current position, a price chart, and performance since acquisition sit alongside them. It serves as a complete, presentation-ready record of the security for the principal and their advisors.

Public markets, private markets, and everything the family owns beyond them.
