Angola’s domestic debt market is the most active segment of its capital markets, dwarfing BODIVA’s equity listings by both volume and investor participation. The government issues Bilhetes do Tesouro (BTs, treasury bills) and Obrigacoes do Tesouro (OTs, treasury bonds) through a regular auction calendar managed by the Banco Nacional de Angola (BNA), creating a yield curve that extends from 91 days to 10 years in local currency, with additional USD-indexed and EUR-indexed instruments for investors seeking hard-currency protection. For fixed income allocators evaluating frontier Africa, Angola’s sovereign curve offers some of the highest real yields on the continent — but accessing those returns requires navigating auction mechanics, liquidity constraints, and currency risk that are materially different from more developed African markets.
Market Structure: BTs and OTs
The Angolan fixed income market is bifurcated between short-dated discount instruments and longer-dated coupon-bearing bonds.
Bilhetes do Tesouro (BTs) are zero-coupon treasury bills issued at 91-day, 182-day, and 364-day maturities. They are sold at a discount to par and redeemed at face value, with the implied yield representing the investor’s return. BTs are the most liquid domestic instruments, with weekly auctions that typically attract demand-to-cover ratios of 1.5x–2.5x. The 364-day BT currently clears at an annualized yield of approximately 14.5–15.5%, reflecting the BNA’s policy rate of 17.5% and market expectations for gradual easing.
Obrigacoes do Tesouro (OTs) are coupon-bearing bonds issued in maturities ranging from 2-year to 10-year tenors. OTs pay semi-annual coupons denominated in kwanza, with coupon rates typically set 100–200 basis points above the prevailing BT yield at the time of issuance. The government also issues Obrigacoes do Tesouro Indexadas (OTx), which are denominated in kwanza but indexed to the USD or EUR exchange rate, providing investors with embedded FX protection. These OTx instruments are particularly popular with foreign holders and Angolan institutions seeking to hedge kwanza depreciation risk.
Yield Curve Analysis
The Angolan kwanza-denominated yield curve currently exhibits a mildly inverted shape at the short end, with 91-day BT yields occasionally exceeding 182-day yields due to liquidity premiums and auction-specific demand dynamics. The curve normalizes from 364 days outward, with the following approximate structure as of February 2026:
| Tenor | Instrument | Approximate Yield |
|---|---|---|
| 91 days | BT | 15.0–15.8% |
| 182 days | BT | 14.8–15.5% |
| 364 days | BT | 14.5–15.5% |
| 2 years | OT-NR | 15.0–16.0% |
| 3 years | OT-NR | 15.5–16.5% |
| 5 years | OT-NR | 16.0–17.0% |
| 7 years | OT-NR | 16.5–17.5% |
| 10 years | OT-NR | 17.0–18.0% |
The curve’s steepness beyond two years reflects two factors: inflation expectations (currently 15.7% year-on-year) and term premium demanded by investors who face genuine uncertainty about fiscal sustainability and debt servicing capacity over multi-year horizons. The spread between the 364-day BT and the 10-year OT is approximately 200–250 basis points, modest by frontier standards but meaningful when compounded over a long hold period.
Real Yields: The Core Attraction
The primary investment case for Angolan domestic fixed income is the real yield — the nominal return adjusted for inflation. With headline CPI running at 15.7% and short-dated BTs yielding 14.5–15.8%, the real yield on short-duration instruments is approximately flat to slightly negative. However, the picture improves meaningfully further out the curve: 5-year OTs yielding 16–17% against a consensus inflation forecast of 12–13% for 2027–2028 imply forward real yields of 300–500 basis points.
For USD-indexed OTx instruments, the calculus is different. These bonds yield approximately 8–10% in dollar terms (depending on tenor), which compares favorably to Nigerian domestic dollar bonds, Zambian eurobonds, and Kenyan infrastructure bonds. The key risk is not inflation but rather the government’s ability to honor the dollar indexation in a scenario of severe kwanza depreciation or FX reserve depletion. Angola’s gross international reserves stood at approximately $14.5 billion as of late 2025, covering roughly 7 months of imports — adequate but not abundant by IMF standards.
Auction Dynamics
The BNA conducts BT auctions weekly and OT auctions on a bi-weekly to monthly schedule, published through the auction calendar. Participation is limited to registered primary dealers — predominantly the major commercial banks including BAI, BFA, BIC, Standard Bank Angola, and Banco Millennium Atlantico — who bid on behalf of their own books and client accounts.
Auction mechanics follow a multiple-price format: each accepted bid is filled at its offered price rather than at a single clearing rate. This creates a winner’s-curse dynamic where aggressive bidders may pay above the marginal clearing yield. In practice, the spread between the highest and lowest accepted yields in a given auction is typically 30–80 basis points, reflecting the information asymmetry between well-connected institutional desks and smaller participants.
The demand-to-cover ratio is the single most watched indicator of auction health. Ratios above 2.0x suggest strong appetite and downward pressure on yields; ratios below 1.2x signal potential stress and may prompt the BNA to reduce issuance size or shorten duration at subsequent auctions. Over the past twelve months, demand-to-cover ratios have averaged approximately 1.8x for BTs and 1.4x for OTs, suggesting adequate but not exuberant demand.
Secondary Market Liquidity
This is the most significant constraint facing fixed income investors in Angola. The secondary market for government bonds operates through BODIVA’s fixed income platform, but trading volumes are thin. Bid-ask spreads on BTs range from 50 to 150 basis points, and on OTs can exceed 200 basis points for off-the-run issues. Most institutional holders adopt a buy-and-hold strategy, given the high coupon income and limited alternative investment options within the Angolan financial system.
The secondary market has improved incrementally since BODIVA introduced electronic matching in 2023, and the CMC (Comissao do Mercado de Capitais) has implemented reporting requirements that increase transparency. However, an investor seeking to exit a material OT position before maturity should expect to accept a discount of 100–300 basis points to the theoretical fair value, depending on tenor and market conditions. This illiquidity premium is effectively a hidden cost that reduces the ex-post real yield.
Foreign Participation and Access
Foreign investors can access Angolan government bonds through two primary channels. The Portal do Investidor, an electronic platform operated by the Ministry of Finance, allows direct registration and participation in primary auctions. Alternatively, foreign institutions can access the market through custody accounts with local banks, which act as intermediaries for both primary and secondary transactions.
The practical barriers include FX conversion risk (all local-currency instruments require kwanza funding), repatriation constraints under BNA regulations, and the documentation requirements for opening a securities custody account. Angola’s current capital account regime, while significantly liberalized since the reforms of 2019–2020, still imposes approval requirements for outward capital transfers above certain thresholds, which can create repatriation delays.
Strategy Recommendations
For investors with a 12–18 month horizon and tolerance for frontier liquidity risk, the optimal positioning in Angolan fixed income is a barbell strategy: overweight 364-day BTs for liquidity and roll yield, combined with a selective allocation to 5-year or 7-year OTs for term premium capture. The BT leg provides a natural reinvestment cycle that benefits from any BNA rate cuts, while the OT leg locks in real yields that are among the highest available in sub-Saharan Africa.
USD-indexed OTx bonds are appropriate for investors who are constructive on Angola’s fiscal trajectory and credit profile (currently S&P B- / Moody’s B3 / Fitch B-) but unwilling to accept outright kwanza exposure. The credit ratings outlook is stable-to-positive, and any upgrade — even a single notch — would likely compress OTx spreads meaningfully, generating capital gains on top of the coupon income.
The key risk to monitor is the fiscal deficit trajectory. Angola’s 2026 budget projects a deficit of approximately 2.5% of GDP, financed primarily through domestic debt issuance. If oil prices — currently around $74.50 per barrel — fall below the budget’s assumed reference price of $65, the government would need to increase issuance volumes or accept higher yields, potentially crowding out private credit and steepening the curve. Conversely, an oil price above $80 would generate windfall revenue that could allow the government to reduce issuance, tightening yields and benefiting existing bondholders.
