In a high-rate market, it is easy to talk about yield first.
For insurance portfolios, I think that order is wrong.
Brazil’s current environment still offers high nominal rates, while inflation has eased only partially. That combination can make fixed-income assets look attractive. But for an insurer, the real issue is not whether an asset looks attractive on its own. The real issue is whether the asset supports the institution’s future payment obligations.
Duration is often discussed as a view on interest rates.
Will rates fall?
Will the curve steepen?
Should the portfolio lock in income now?
Those questions matter, but they are not enough.
An insurance company needs to begin from the liability side. Claims, reserves, policyholder behavior, liquidity requirements, and capital rules all shape the correct maturity profile.
A portfolio that is too short may look safe today, but it can create reinvestment risk if rates fall before long-term liabilities are funded.
A portfolio that is too long may support future income, but it can also create liquidity pressure if the institution needs cash earlier than expected.
That is why I use duration as a tool, not as a conviction.
My basic review is:
First, identify the payment schedule.
Second, match asset cash flows to the relevant liability buckets.
Third, keep enough liquidity before maturity.
Fourth, stress the portfolio under different rate and claims scenarios.
Fifth, check whether the capital budget still supports the position.
The point is not to avoid duration risk entirely. No insurance portfolio can avoid all risk.
The point is to hold duration risk in a form that is compatible with future payments.
In Brazil, high yields can help insurers earn income. But yield alone cannot decide the correct structure.
A useful portfolio should answer one practical question:
Can this institution continue paying if the next rate path is different from the one we expected?
That is why liability discipline matters more than market confidence.
