BlackRock Bond Income Portfolio
Actively managed U.S. bond fund
As of its 2026 Q2 report, BlackRock Bond Income Portfolio held 4,021 positions with $2.49B in net assets. Its ten largest holdings made up 14.4% of the fund. Its share classes cost 0.38%–0.63% a year. Over the 12 months to May 2026, it returned 5.8%, with dividends reinvested. In 2026 Q2 it added 810 new positions and exited 957.
Competitive total return primarily from investing in fixed-income securities.
The fund is subadvised by BlackRock Advisors, which invests at least 80% of assets in fixed-income securities selected by establishing duration targets based on economic and monetary factors, allocating across bond sectors and yield curve positions based on relative price and yield attractiveness, and relying on credit quality and interest rate sensitivity analysis of individual securities. The fund may hold up to 20% in high yield securities and up to 20% in foreign securities, provided combined high yield and foreign exposure does not exceed 30%. Because security selection depends on BlackRock's evaluation of relative attractiveness across sectors and maturities, portfolio composition will diverge from any benchmark.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Securitized | 58.48% |
| Bonds | 46.86% |
| Cash & short-term | 2.78% |
| Loans | 0.95% |
| Stocks | 0.63% |
| Derivatives | -0.29% |
These positions come to 109.41% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.
The outer band is exposure held short — written against the portfolio rather than part of it, which is why it sits outside the ring and why the two are never netted into one figure.
Derivatives are shown at market value, not notional exposure.

How it has done
C000017802 share class · total returns with dividends reinvested
Volatility over the last 12 months: 3.80%. Past returns are a record, not a forecast.
Jun 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
This fund changed legal form during the period shown. The history above is continuous — it spans both eras, and the change is not a gap in reporting.

Turnover is how much of the portfolio was replaced in a year.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-06-30
Share of the fund's debt by how its coupon behaves — the fact that decides whether a rate move reaches this portfolio at all.
| Fixed rate | 75.9% |
| Floating rate | 23.6% |
| Zero-coupon or unclassified | 0.4% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 4.7% |
| 1-3y | 6.8% |
| 3-5y | 11.6% |
| 5-10y | 11.9% |
| 10y+ | 65.0% |
These three overlap — one holding can be in arrears and paying in kind at once — so they are shown separately and never summed.
Risk profile
Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2
Most of this fund’s sensitivity is to interest rates, with credit spreads carrying a small fraction as much.
Where the loss would come from. The two shocks are the same size, so this is the balance of the fund's two sensitivities rather than a bet on one moving more.
| Interest rates | 75% |
| Credit spreads | 25% |
Filers report the impact of a 0.01% move only, so the total is our own scaling of that one number and overstates the loss on most bonds — read it as approximate, never as precise. The two sensitivities overlap rather than add up: they measure the same positions against different shocks, which is why the durations above are shown side by side and never summed.
Share of the fund's spread duration carried by each credit tier.
| Investment grade | +1.58 yr |
| High yield | +0.35 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 3 mo | 0.04 yr | 1% |
| 1 yr | 0.64 yr | 11% |
| 5 yr | 1.56 yr | 27% |
| 10 yr | 2.28 yr | 40% |
| 30 yr | 1.21 yr | 21% |
| 3 mo | 0.02 yr | 1% |
| 1 yr | 0.28 yr | 14% |
| 5 yr | 0.64 yr | 33% |
| 10 yr | 0.62 yr | 32% |
| 30 yr | 0.38 yr | 20% |
The two bands measure the same positions against different shocks and do not add — a Treasury carries rate duration and no spread duration, a floating-rate credit the reverse. Rate tenors are also summed across every currency the fund discloses.

Duration contribution in years, summing to the fund's 5.73 yr.
This is where the fund's rate exposure sits, not its currency risk — most international bond funds hedge the currency back to dollars, and the size of those hedges is not in the filing. Tenors are also summed across curves, so a 5-year JPY point and a 5-year USD point are added together.
