THE SHORT ANSWER
TexSTAR gives Texas issuers daily access to bond proceeds at a floating rate published on its home page. Whether proceeds earn more there or in a competitively bid GIC, flex repo or Treasury portfolio depends on the fund's draw schedule, the term a bid can lock and the path of short-term rates; bond counsel and tax counsel settle the legal limits.
Whether a Texas issuer should keep bond proceeds in TexSTAR comes down to the fund's draw schedule and the rate path: the pool keeps funds reachable daily at its published floating rate, and a competitively bid GIC, flex repo or Treasury portfolio sets rate and terms by contract, specified against the issuer's stated draw schedule.
Texas law frames the choice: Texas Government Code Chapter 2256, the Public Funds Investment Act, governs how state agencies, local governments and investment pools invest their funds.
What is TexSTAR and who can invest in it?
TexSTAR is a local government investment pool created under the Interlocal Cooperation Act and administered by HilltopSecurities and JP Morgan, described on its program information page as tailored to Texas state and local government investment objectives.
According to TexSTAR's website (accessed Oct. 2026, where no as-of date is given for the rating), the fund is rated AAAm by Standard & Poor's, maintains a maturity of 60 days or less with a maximum of 13 months for any individual security, and seeks to maintain a constant dollar value.
For a pool, §2256.016(a) requires a rule, order, ordinance or resolution authorizing the particular pool, §2256.016(b) requires pool disclosure items, and §2256.019 requires a public funds investment pool to be continuously rated no lower than AAA or AAA-m or an equivalent rating by at least one nationally recognized rating service.
Bond proceeds narrow further: under §2256.0208, a local government's investment officer may invest bond proceeds or pledged revenue only to the extent the chapter permits, in accordance with the statute governing the debt issue and the entity's investment policy for that issue.
The rating floor also carries a consequence: under §2256.021, an investment that loses a minimum rating required under the subchapter stops being authorized while it is unrated, and the entity must take prudent measures to liquidate it.
The state-law frame behind these provisions is laid out in the guide to Texas permitted investments.
How is TexSTAR's yield set?
TexSTAR's yield is set by its portfolio, which maintains a maturity of 60 days or less, with a maximum of 13 months for any individual security, and seeks to maintain a constant dollar value, so the rate it publishes is not one fixed for a term.
The pool publishes its current rate, 7-day net yield, weighted average maturity and market value per share on its home page.
That floating structure is the comparison with a bid: a fixed-rate agreement negotiated for a stated term keeps one rate while the market moves, so whether the pool or the bid earns more over a holding period depends on the path of short-term rates after the money is placed.
For the market side of that comparison, mGIC's today's reinvestment rates page links the Treasury yield curve, SOFR and the SLGS rate table to their official sources.
How do arbitrage and rebate tracking work for proceeds held in a pool?
A pool deposit does not move bond proceeds outside the federal arbitrage rules: under IRS Publication 5271, the bonds themselves are tested under both the yield restriction rules of §148(a) and the rebate rules of §148(f), and failing either set makes them arbitrage bonds.
The two tests do not excuse each other: Publication 5271 notes that even when the yield restriction rules allow an issuer to invest above the bond yield, the rebate rules may still require those earnings to be paid to the U.S. Treasury.
On the pool side, TexSTAR lists "Bond Proceeds Management" and "Arbitrage Rebate Services" among its specialized services, offered through HilltopSecurities and JP Morgan, alongside investment policy services and direct debt service payments to paying agents.
The program page does not describe the terms, cost or scope of those services, so a listed service is a service rather than a determination: whether an issue's pool earnings sit inside its rebate computation is concluded for the issue by tax counsel, and the rebate requirement guide explains what that computation covers.
The tracking cadence on the Texas side is set by statute: §2256.023 requires the investment officer's written report on the entity's investments at least quarterly.
The general trade-offs of pool deposits are covered in the guide to local government investment pools.
Liquidity: same-day access or a draw-matched agreement?
TexSTAR's information page describes daily access to funds with no penalties and no minimum balance, interest accrued daily and paid monthly, same-day wire settlement for transactions started by 4:00 pm Central, and next-day settlement for ACH requests made by that time.
Transactions can also be preloaded up to 10 business days ahead.
The contrast with a draw-matched agreement is structural: the pool keeps funds reachable daily on the pool's published terms, and a GIC or repo sets the timing inside its own contract, in its withdrawal provisions.
When would a GIC, flex repo or Treasury portfolio earn more than TexSTAR?
None of the three earns more by definition: each differs from the pool in term, rate structure, credit and withdrawal terms, and which side comes out ahead is settled by a specific issue's schedule and by what providers actually bid on the day.
The general pool-versus-bid comparison is the LGIP vs GIC guide, so what follows is the Texas frame for each structure.
Texas expressly authorizes a guaranteed investment contract for bond proceeds when it has a defined termination date and is secured by U.S. or agency obligations at least equal to the bond proceeds invested, pledged and deposited with the entity or a third party it selects and approves, under §2256.015(a), an authorization that covers bond proceeds rather than general operating funds.
The term is capped: bond proceeds may not be invested in a GIC with a term longer than five years from the date the bonds are issued, except for reserves and funds maintained for debt service purposes, under §2256.015(b).
Repurchase agreements carry their own authorization under §2256.011: a defined termination date, collateral of cash and U.S. or agency obligations (or other obligations the section lists) pledged and held in the entity's name with the entity or an approved third party, placement through a primary government securities dealer or a financial institution doing business in Texas, and underlying obligations with a market value of not less than the principal disbursed when the funds are disbursed.
U.S. and agency obligations under §2256.009(a)(1) and SEC-registered no-load 2a-7 money market funds under §2256.014(a) are authorized directly, which is the legal base for a structured Treasury portfolio matched to a draw schedule.
Procurement is part of the GIC authorization itself: §2256.015(c) requires the bond order, ordinance or resolution to specifically authorize GICs, bids from at least three separate providers with no material financial interest in the bonds, purchase of the highest-yielding qualifying bid, a price reflecting the reasonably expected drawdown schedule, and a provider certification of administrative costs.
That state-law track is separate from the federal fair-market-value safe harbor in Treas. Reg. §1.148-5(d)(6)(iii), which treats a GIC's purchase price as fair market value on the purchase date when all of its requirements are met, requirements the fair market value safe harbor guide sets out in full.
| Structure | Texas authority | Rate behavior | Access to funds |
|---|---|---|---|
| TexSTAR (pool) | §2256.016(a) authorization; §2256.019 rating floor | Set by a portfolio with a maturity of 60 days or less (13 months maximum for any individual security) | Daily, same-day wire by 4:00 pm CT |
| GIC | §2256.015(a); 5-year cap in §2256.015(b) (reserves and debt service funds excepted) | Fixed for the term, set through the bid | Per the contract's withdrawal provisions |
| Full-flex repo | §2256.011(a), (b)(2) | Per the agreement's pricing terms | Per the agreement's withdrawal terms |
| Treasury portfolio with a money-market allocation | §2256.009(a)(1); §2256.014(a) | Set by the securities bought, across their maturities | Matched to cash needs, with a money-market allocation for faster spend-down |
Can an issuer use both: the pool for near-term draws and a bid for the rest?
On the statutes' face, both can be authorized: §2256.016(a) lets a governing body authorize a pool, §2256.015 authorizes GICs for bond proceeds, and §2256.005 requires the entity to adopt a written investment strategy for each fund or group of funds that both would have to fit.
That strategy has a statutory shape: the policy must emphasize safety of principal and liquidity, the per-fund strategy runs in the order suitability, preservation and safety of principal, liquidity, marketability, diversification and yield under §2256.005(d), and §2256.006(a) sets the overall order as safety, liquidity, yield.
Where the split lands, the bid side is specified against the schedule: the federal solicitation rule requires GIC bid specifications to take into account the issuer's reasonably expected deposit and drawdown schedule, under Treas. Reg. §1.148-5(d)(6)(iii)(A)(5).
mGIC helps issuers evaluate and competitively bid guaranteed investment contracts, full-flex repurchase agreements and structured Treasury portfolios, selling none of them, and as an independent, SEC-registered municipal advisor it does not act as principal and owes its municipal clients a fiduciary duty.
Its Bidding Agent work runs from bid specifications through soliciting qualified providers, managing questions and comparing bids on rate and non-rate terms, and when a bid closes its fee is paid by the winning provider rather than the issuer, at or below the safe-harbor maximum in the Treasury arbitrage regulations, and disclosed.
For issuers weighing a pool position, mGIC's reinvestment review compares it against the fund's objectives, permitted investments, projected draw schedule, credit parameters, market conditions and timing, and a free, no-obligation conversation about a TexSTAR holding or any other bond-proceeds investment is the place to start.
Which structure a given fund may hold, and how the arbitrage and rebate rules treat it, are conclusions for bond counsel and tax counsel.
Frequently asked questions
Does TexSTAR compute an issuer's arbitrage rebate?
TexSTAR lists 'Arbitrage Rebate Services' among its specialized services, offered through HilltopSecurities and JP Morgan, but the program page does not describe the terms, cost or scope of the service. Whether an issue's pool earnings sit inside its rebate and yield restriction rules is a determination for tax counsel.
Can a Texas issuer put bond proceeds in TexSTAR?
The PFIA lets a local government's investment officer invest bond proceeds only to the extent the chapter permits, in line with the statute governing the debt issue and the entity's investment policy for that issue, under §2256.0208, and it requires a rule, order, ordinance or resolution authorizing the particular pool under §2256.016(a), with the pool continuously rated no lower than AAA or AAA-m or an equivalent rating under §2256.019. Whether a specific deposit fits a specific issue is a question for bond counsel.
What rating does TexSTAR have?
TexSTAR's website states the fund is rated AAAm by Standard & Poor's, with no as-of date shown, as accessed in October 2026. Texas requires a public funds investment pool to be continuously rated no lower than AAA or AAA-m or an equivalent rating by at least one nationally recognized rating service under §2256.019.
How quickly can money be withdrawn from TexSTAR?
The program's information page describes daily access with no penalties and no minimum balance, same-day wire settlement for transactions started by 4:00 pm Central, and next-day settlement for ACH requests made by that time. Transactions can be preloaded up to 10 business days ahead.
What does Texas require to bid a GIC on bond proceeds?
Under §2256.015(c), the bond order, ordinance or resolution must specifically authorize GICs, the entity must receive bids from at least three separate providers with no material financial interest in the bonds, it must buy the highest-yielding qualifying bid priced to the reasonably expected drawdown schedule, and the provider must certify the administrative costs reasonably expected to be paid to third parties.
