THE SHORT ANSWER

Neither instrument fits every fund. A state pool keeps bond proceeds reachable on the pool's published terms at a variable rate, and a GIC fixes one rate for a stated term built to a draw schedule. State statutes, the bond documents and the arbitrage rules decide which is available for a given fund, and bond counsel and tax counsel make the final determinations.

A state investment pool and a competitively bid guaranteed investment contract solve two different problems with the same dollars: the pool keeps proceeds reachable on the pool's published terms at a rate that moves, and the GIC fixes one rate for a stated term built to a draw schedule.

This guide compares a local government investment pool (LGIP) with a guaranteed investment contract (GIC), in the order mGIC applies to reinvestment decisions: safety, liquidity, yield, in that order.

Which funds fit a pool, and which fit a GIC?

A pool fits proceeds whose spending date and amounts are still moving, and a GIC fits proceeds with a horizon the issuer can state and a drawdown it can schedule.

A construction fund can sit in both instruments across its life: draws that are still estimates stay in daily-dealing holdings, and once the schedule firms up the remaining balance can be bid to a term, the sequencing the draw schedule guide works through.

A debt service reserve fund sits nearer the term end: its spending date is a call on the reserve, not a construction invoice.

A pool can carry the drawdown pattern in its own account types: LAIF's separate bond proceeds accounts take a one-time deposit with no cap on a monthly drawdown schedule and close automatically at zero balance.

How does an LGIP work, and how does a GIC work?

The MSRB glossary defines a local government investment pool as an investment pool established by a state or local governmental entity that serves as a vehicle for investing public funds of participating governmental units, with participants buying shares or units, often in a trust.

Each pool states its cost differently: TexPool's fee is 0.045% a year and TexPool Prime's 0.055%, calculated daily on the pool balance and deducted from interest earnings, with rates quoted net of fees, as of October 6, 2026.

Texas CLASS caps its administrator's sliding-scale fee at 12 basis points on assets up to $1 billion, deducted from portfolio earnings, a figure that excludes the separately listed custodian and other program costs.

LAIF sets its cost as a statutory ceiling instead: administrative costs may not exceed 5% of quarterly earnings under Gov. Code §16429.1, or 8% for the following fiscal year if the 13-week Daily Treasury Bill Rate is below 1% on the last day of the fiscal year, a cap on cost rather than a stated charge.

The MSRB glossary defines a guaranteed investment contract as an investment secured by a contract with a financial institution that guarantees a fixed rate of return and a fixed maturity, its general definition.

For arbitrage purposes, Treas. Reg. §1.148-1(b) counts as a GIC any nonpurpose investment with specifically negotiated withdrawal or reinvestment provisions and a specifically negotiated interest rate, which is how a bond-proceeds GIC can carry a draw schedule instead of a single maturity.

Providers price a GIC against the issuer's written bid specifications, and the guide to how GIC rates are set follows that pricing.

Accounting differs as well: GASB Statement No. 79, issued December 23, 2015, lets qualifying external investment pools measure investments at amortized cost so participants can report pool investments at amortized cost, and New Jersey moved its pool standard to that GASB standard, as Local Finance Notice 2017-24R explains.

How does safety compare: credit, collateral and custody?

The two risk shapes differ before any name is attached: a pool spreads exposure across its portfolio, a GIC concentrates it in one provider's contract.

GFOA notes in general that LGIPs are not registered with the SEC, that investments in them are not insured or guaranteed, and that substantial losses have occurred in the past, with the authorizing entity typically not guaranteeing pool investments.

Individual pools carry their own language: TexPool and TexPool Prime seek to maintain a $1.00 value per share as the Texas Public Funds Investment Act requires, and the pools' materials state that it is possible to lose money by depositing money in the pool.

Texas CLASS manages its stable funds to a $1.00 NAV while stating in its Information Statement that there is no guarantee the stable NAV will be kept.

Ratings are dated facts rather than permanent labels: 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 Gov't Code §2256.019, and CalTRUST's August 31, 2026 materials listed its Liquidity Fund at S&P AAAm with same-day liquidity, next-day Short-Term and Medium-Term funds carrying AAf/S1+ and AA-f/S1 ratings that are not stable-NAV products.

State law can require the GIC's promise to be backed: Texas requires a bond-proceeds GIC to have a defined termination date and to be 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 Gov't Code §2256.015(a), an authorization covering bond proceeds rather than operating funds.

Custody follows the instrument: Washington's pool statute requires a separate account per participant and a monthly report under RCW 43.250.070, while a GIC holder owns a contract rather than portfolio securities, so its credit and collateral terms sit in the documents rather than in an account.

Provider downgrades are the GIC's own subject, covered in GIC credit protection.

How does liquidity compare: withdrawal flexibility?

A pool is built for the issuer's timing within published limits, and a GIC fixes the timing in the contract.

Texas CLASS and Texas CLASS Government manage to a stable $1.00 NAV with daily liquidity and no minimum or cap on what a participant may invest, caution that the trust may suspend or postpone payments in certain market disruptions without prior notice, and run Term Series portfolios as separate fixed-term investments with early-withdrawal penalties.

STAR Ohio reserves the right to limit a participant's transactions to $250 million per day across all its accounts and asks for 24 hours' notice on purchases or redemptions of $100 million or more, processing same-day requests received by 2:00 pm Eastern, with no minimum or maximum investment and no transaction fees.

Utah's PTIF requires at least 48 hours' advance notice to withdraw more than $20 million, settles requests made before noon the next business day, and states that the fund is not intended to be a substitute for a treasurer's operating accounts.

LAIF caps regular accounts at $75 million, allows 15 transactions a month between $5,000 and $75 million each, asks for one day's notice on deposits or withdrawals of $10 million or more, credits same-day for transactions completed by 10:00 am, and accepts scheduling up to 10 calendar days ahead, limits set administratively as of the June 30, 2026 Information Digest.

Gates are the disclosed tail risk: Florida law lets the SBA executive director limit Florida PRIME contributions or withdrawals for 48 hours after a material liquidity event, extendable by its trustees for up to 15 more days under Fla. Stat. §218.409(8)(a), while the pool's June 30, 2026 disclosures reported no redemption fees or transaction limits on daily access to 100 percent of account value.

A cap is the other disclosed limit: the Oregon LGIP's ORS 294.810 limit rose from $63,387,000 to $65,463,000 effective August 31, 2026, according to the Oregon Treasury's September 29, 2026 memo, an amount recalculated each year.

A GIC runs the other direction: the contract's withdrawal provisions set when money leaves and on what terms, which the guide to GIC withdrawal provisions details.

Why do pool yields and GIC rates differ?

A pool's rate moves as its portfolio reprices under it, and a GIC's rate is negotiated once for a whole term, so the comparison changes with the holding period.

Neither number belongs in a guide: pool rates change daily and each pool publishes its own current figure, and a GIC rate exists only inside a specific bid and contract.

When parked proceeds earn less than the bond yield, the gap between the two is what the negative arbitrage guide covers.

On the GIC side the fee mechanics sit inside the bid: the winning bid must be the highest-yielding bona fide bid determined net of any broker's fees under Treas. Reg. §1.148-5(d)(6)(iii)(C)(1).

Which side a fund lands on is a same-day, same-draw-schedule question, the one a reinvestment review runs.

How do compliance and procurement differ?

The pool route is decided in eligibility documents: state statutes, the pool's offering statement, the indenture's permitted-investment section and the bond covenants.

Texas requires a rule, order, ordinance or resolution specifically authorizing the particular pool under Gov't Code §2256.016(a), on top of the §2256.019 rating floor.

California allows a local agency, with its governing body's approval, to deposit bond, note or COP proceeds in LAIF pending expenditure under Gov't Code §16429.1(d), with the Controller keeping a separate account for each deposit and the trustee or fiscal agent alone deciding how long the proceeds stay on deposit under §16429.1(f).

Washington's RCW 43.250 counts issuers of bonds or COPs for financing contracts approved under RCW 39.94.040 among eligible participants, leaves investment time periods and withdrawal procedures to state treasurer rule, and requires a separate account and monthly report per participant.

Pools flag the limits themselves: Oregon's LGIP Information Statement says Treasury and its agents make no representations as to whether the pool complies with Section 148 of the Internal Revenue Code, that the pool may not be appropriate for the investment of bond proceeds, and that participants should discuss arbitrage rebate and yield restriction with bond counsel first.

Oregon's statement is Oregon's own, and the general point travels: eligibility is judged issue by issue, in the indenture's permitted investments and the covenants.

Some pools market services that touch the arbitrage side: TexSTAR lists "Bond Proceeds Management" and "Arbitrage Rebate Services" among its specialized services, offered through HilltopSecurities and JP Morgan, without describing their terms, cost or scope, and PSDLAF markets a "Bond Proceeds Investment" program that includes third-party arbitrage rebate monitoring at no cost, without describing the scope or provider of the monitoring.

A listed service is not a determination: whether proceeds in a pool stay inside an issue's yield and rebate rules is concluded for the issue by bond counsel and tax counsel, not by the deposit.

GFOA's pool checklist reads like a procurement file: confirm the pool is an eligible investment, read its offering statement, investment policy and audited financials, and check whether it seeks a constant or fluctuating NAV.

A GIC adds a procurement record: Treas. Reg. §1.148-5(d)(6)(i) rebuttably presumes that any investment not traded on an established securities market is not bought or sold at fair market value, and the safe harbor in §1.148-5(d)(6)(iii) treats a GIC's purchase price as fair market value on the purchase date when all its requirements are met.

Those requirements, from written specifications through at least three qualifying bids to the provider certification, are the fair market value safe harbor the bidding guides set out in full, and because that safe harbor runs only to GICs and yield-restricted defeasance escrow investments, how the (d)(6)(i) presumption bears on a given pool deposit is for bond counsel and tax counsel to judge for the issue.

State law layers on top: Texas requires the bond order to specifically authorize GICs, at least three bids from separate providers with no material financial interest in the bonds, and purchase of the highest-yielding qualifying bid whose price reflects the reasonably expected drawdown schedule, under Gov't Code §2256.015(c), separate from the federal safe harbor.

Texas also bars a bond-proceeds GIC with a term longer than five years from the bonds' issue date, except for reserves and funds maintained for debt service purposes.

Georgia shows the drafting variation: its bond-proceeds statute lists "interest-bearing time deposits, repurchase agreements, reverse repurchase agreements, rate guarantee agreements, or other similar banking arrangements" from a bank or trust company with at least $50 million in capital and surplus, a primary dealer with at least $50 million in capital, or a registered bank holding company, and the statute does not use the words "guaranteed investment contract" or list insurers among the counterparties.

Frequently asked questions

Can bond proceeds be deposited in a state investment pool at all?

State by state. California's Gov. Code §16429.1(d) lets a local agency deposit bond, note or COP proceeds in LAIF pending expenditure with its governing body's approval, Texas requires a rule, order, ordinance or resolution specifically authorizing the particular pool under §2256.016(a), and Washington's RCW 43.250 lists entities issuing bonds or COPs for financing contracts approved under RCW 39.94.040 among eligible participants, though the chapter has no bond-proceeds-specific rule.

Is money in a state pool automatically free of arbitrage problems?

No. Oregon's LGIP Information Statement says Treasury and its agents make no representations as to whether the pool complies with IRC Section 148, that the pool may not be appropriate for bond proceeds, and that participants should discuss arbitrage rebate and yield restriction with bond counsel first. Services some pools market, such as TexSTAR's listed 'Arbitrage Rebate Services' or PSDLAF's third-party monitoring, are services rather than legal conclusions for an issue.

What stops a pool from limiting withdrawals in a crisis?

Pools disclose the mechanics. Florida law lets the SBA executive director limit Florida PRIME contributions or withdrawals for 48 hours after a material liquidity event, extendable by its trustees up to 15 more days, and Texas CLASS notes the trust may suspend or postpone payments in certain market disruptions without prior notice. Florida PRIME's June 30, 2026 disclosures reported no redemption fees or transaction limits on daily access to 100 percent of account value.

Does the GIC bidding safe harbor cover a state pool deposit?

Treas. Reg. §1.148-5(d)(6)(iii) covers guaranteed investment contracts and yield-restricted defeasance escrow investments, while the rebuttable fair market value presumption in §1.148-5(d)(6)(i) reaches any investment not traded on an established securities market. How a pool deposit is treated for an issue is for bond counsel and tax counsel. Separately, Texas requires at least three bids from separate providers with no material financial interest in the bonds for a GIC under §2256.015(c), and a specific authorizing rule, order, ordinance or resolution for a pool under §2256.016(a).

Do pools report at amortized cost for accounting?

GASB Statement No. 79, issued December 23, 2015, lets qualifying external investment pools measure investments at amortized cost, and pool participants can then report their pool investments at amortized cost. New Jersey moved its pool standard from the SEC 2a-7 model to that GASB standard, as Local Finance Notice 2017-24R explains.
