Frequently Asked Questions about Mortgage vs Bonds Arbitrage

Interest rate arbitrage involves maintaining a low-interest debt (3% or 7%) while investing spare funds into a secure, higher-yielding asset (15–16% bonds). It is completely legal and a standard wealth-building strategy globally.

No. Under the current Tax Code of Ukraine, individuals' income from government bonds (OVDP) is exempt from Personal Income Tax and Military Levy. Check the current rules before buying, especially if you are a tax resident of another country.

Early repayment only makes financial sense when your loan rate exceeds secure risk-free investment returns (e.g. commercial bank mortgages at 16–20% or consumer loans).

The interest rate is legally locked into your loan agreement with the commercial partner bank for the full contract term under statutory state guarantees.

Self-funding occurs when your bond portfolio grows large enough that monthly coupon payouts equal or exceed your mortgage payment. From that point on, bond earnings service the mortgage automatically.
