South Dakota Revives Push for a State Bitcoin Reserve With 10% Allocation Cap

South Dakota is back at the table on a state-level Bitcoin allocation. Republican Representative Logan Manhart has reintroduced a proposal that would let the state’s investment funds hold Bitcoin—directly or through an exchange-traded product—capped at 10%. He framed the filing with a simple message on X: “Strong money. Strong state.”

What HB 1155 actually does - Authorizes up to 10% of South Dakota’s investment portfolio to be allocated to Bitcoin, either custodied by the state or via an exchange-traded product. - Covers pools that finance core services such as education, healthcare, and retirement. - Lands at a time when the South Dakota Investment Council, with $20.56 billion under management, reported a 5.5% return last year versus a 12.5% benchmark, per its 2025 annual report. More than half of the portfolio sits in public equities, with smaller sleeves in real estate and debt.

Why a second try now Manhart’s first attempt in early 2025 didn’t advance. After a February reading, the bill went to the House Commerce and Energy Committee, which voted 9–3 to push it to a “41st day”—a procedural move that, in a 40-day session, effectively ends consideration. The renewed filing arrives as President Donald Trump’s pro-crypto stance has encouraged similar state proposals, often sponsored by aligned lawmakers.

The broader state-level picture - At least 28 states have submitted some version of a “Bitcoin reserve” bill, according to a public tracker. Many hit a wall: 33 measures have been shelved, often early in committee. Nine proposals across six states are still live. - Only three states—Arizona, New Hampshire, and Texas—have enacted reserve-related statutes, and execution remains limited: - Arizona: Repeated attempts at a full strategic reserve have been blocked by the governor’s office; a narrower reserve for seized assets moved forward in May last year. - New Hampshire: Permits up to 5% of funds in digital assets with a market cap above $500 billion—effectively Bitcoin only. It’s unclear if the state has bought any, though a Bitcoin-backed bond is planned for later this year. - Texas: Can allocate up to 5% to Bitcoin; so far, it has purchased roughly $5 million. - Momentum continues: Arizona’s Senate Financial Committee narrowly advanced SB 1044 (4–3) to exempt virtual currency from property taxes. Kansas introduced its own strategic reserve bill.

The real fight isn’t the headline “10%”—it’s operational design Setting a ceiling is easy; building a playbook that protects taxpayer-backed liabilities is the work. A 10% authorization without defined execution guardrails invites volatility to drive politics rather than policy. A few choices will matter more than the cap itself:

- Implementation path: A staged allocation (for example, a small pilot with predefined growth bands) and dollar-cost averaging can reduce timing risk. Volatility-targeted rebalancing and drawdown triggers add discipline in stressed tape. - Vehicle selection: Direct custody offers sovereignty but introduces key management, multi-signature governance, insurance, audit, and disaster-recovery demands that many public entities haven’t staffed. Exchange-traded products simplify ops and disclosure but add management fees, market-hour constraints, and tracking slippage. - Risk framing: Tying Bitcoin exposure to a clear objective—diversification, inflation protection, or return-seeking—sets expectations for constituents who fund schools and pensions. Without that framing, a 50% drawdown could become a legislative event rather than a portfolio event. - Governance and ethics: Fiduciary duty in public funds often favors process over prediction. Codified oversight, segregation of duties, and transparent reporting cadence help ensure the allocation serves beneficiaries rather than political cycles.

Experience from Arizona, New Hampshire, and Texas suggests that legal authorization rarely translates into immediate, sizable purchases. Procurement rules, custody readiness, and committee oversight often slow the move from statute to held sats. If South Dakota advances HB 1155, those same operational details will likely decide whether the state ever approaches the 10% ceiling—or remains at a token allocation while the framework matures.
