Credit Suisse gold bars remain IRA-eligible if the bar is .9999 fine and arrives in its original sealed assay card. Valcambi struck them on Credit Suisse’s behalf from the early 1980s through the UBS acquisition that closed in 2023.

The eligibility test sits in IRC §408(m)(3)(A). The statute requires a .995 minimum fineness and a refiner accredited by the London Bullion Market Association or approved by a recognized commodity exchange. Valcambi is the actual refiner behind every Credit Suisse bar. It holds LBMA Good Delivery accreditation and is COMEX-approved, so the statute is satisfied through the Valcambi chain.

The wrinkle for retirement buyers in 2026 is that no new Credit Suisse branded bars are being produced. Existing Credit Suisse inventory still circulates on the secondary market, but the discontinued brand has attracted a documented uptick in counterfeit product. Verifying authenticity before the bar enters depository custody is now the single largest variable cost on a Credit Suisse IRA order.

This article covers the statutory basis for eligibility and the sizes still routinely encountered on the secondary market. It also covers the authentication chain depositories require, the premium structure for a discontinued brand, the dealer-to-depository acquisition flow, and the four mistakes that erode value on a Credit Suisse IRA order.

For a first-time IRA buyer about to authorize a Credit Suisse bar order on the secondary market, the dealer running the trade matters more than the refiner stamp on the bar. See the 2026 OPRS dealer verdicts for the BBB record and complaint history behind each clear-or-warn decision before the custodian wires payment.

Statutory eligibility under IRC §408(m)(3)(A)

The Internal Revenue Code prohibits IRAs from holding collectibles under IRC §408(m)(1). Paragraph (3) of that section carves out a narrow exception for specified bullion. Subparagraph (A) reaches gold bullion bars.

A bar is eligible if it meets a minimum fineness of .995, and if it is refined by a person accredited by the LBMA or approved by a recognized commodity exchange. The statute does not name Credit Suisse by brand; it incorporates the LBMA Good Delivery framework by reference.

The Credit Suisse bar passes both prongs of the test through Valcambi. Standard Credit Suisse gold bars are struck at .9999 fineness (four-nines, the same purity grade as the PAMP and the Royal Canadian Mint bars). The .995 fineness floor in the statute is therefore easily met.

The refiner credential runs through Valcambi SA, the Swiss refinery in Balerna that produced Credit Suisse-branded bars under contract from approximately 1980 through 2023. Valcambi holds LBMA Good Delivery accreditation for gold and silver, and is an approved refiner on the CME Group COMEX gold contract. Either credential alone satisfies IRC §408(m)(3)(A); Valcambi holds both.

The practical implication is that the Credit Suisse brand mark and the Valcambi underlying refinery hallmark frequently appear together on the same bar (look on the reverse for the Valcambi cross-and-shield mark alongside the Credit Suisse logo). An IRS-approved depository booking a Credit Suisse bar will check both. A bar with a Credit Suisse stamp and no Valcambi mark, or with mismatched serial numbers between the bar face and the assay card, will not be booked into IRA storage.

The Credit Suisse, PAMP Suisse, Valcambi, Royal Canadian Mint, Perth Mint, Heraeus, and Argor-Heraeus families of bars are the LBMA-accredited products routinely accepted by U.S. self-directed IRA depositories. IRS Publication 590-A reflects the same framework in its general listing of approved precious metals.

The Credit Suisse sizes still routinely encountered on the secondary market

Credit Suisse branded bars were issued across a wide weight range over their four decades in production. The catalog ran from 1 gram retail product up through the LBMA Good Delivery 400 oz bar reserved for institutional settlement. The sizes that still show up in secondary-market dealer inventory in 2026 cluster around eight weights, all at .9999 fineness.

For IRA orders specifically, the 1 oz, 100 g, and 1 kilo bars are the three most-routed sizes when dealers can source them. The 10 oz bar in the Credit Suisse line is less common than the equivalent PAMP 10 oz. Credit Suisse historically pushed the 100 g size as its mid-tier institutional bar instead.

The sub-ounce bars (1 g through 10 g) are predominantly retail and gifting product. They carry a markedly higher per-ounce premium than the larger bars and tend to be inefficient for retirement-allocation orders.

Secondary-market availability is the binding constraint, not preference. Because no new bars are being struck, dealer inventory in 2026 depends on what is being sold back from estate liquidations, broker resales, and private collections. A buyer pre-committed to a specific Credit Suisse size may need to wait for inventory rather than place an at-market order. PAMP Suisse and Valcambi (which still produces new bars) are the in-production substitutes for buyers who cannot tolerate inventory delay.

Premium structure for a discontinued brand in 2026

Industry-reported dealer premiums on secondary-market Credit Suisse bars in 2026 track close to PAMP Suisse on the larger sizes but show wider variance on smaller bars. The reason is sourcing friction: a dealer who acquires a five-bar lot at an estate liquidation will price the resale on the per-bar acquisition cost, not on a continuous production run. The FINRA Investor Alert on precious metals notes the same dynamic across discontinued or scarce-supply bullion products.

Major-dealer published rate sheets for secondary-market Credit Suisse bars in 2026 typically show the following premium midpoints over the LBMA AM gold fix.

• 1 g through 10 g bars: 9 to 20 percent over spot
• 1 oz bars (sealed in original Credit Suisse assay card): 5 to 8 percent over spot
• 100 g bars: 3 to 5 percent over spot
• 1 kilo bars: 2.5 to 4.5 percent over spot
• Authentication-required (unsealed or re-packaged): subtract 1 to 3 percent from buy-back, premium varies on resale

The Credit Suisse 1 oz premium sits roughly 1 percentage point above the equivalent PAMP cast 1 oz in 2026. That premium reflects the secondary-market sourcing cost rather than a brand-recognition surcharge. The kilo bar remains the cost leader on a per-ounce basis. Sub-ounce bars are the most expensive per ounce of metal delivered, with the discontinued-brand premium adding roughly 1 to 2 percentage points over equivalent PAMP gram bars.

For a retirement-focused IRA buyer, the implication is straightforward. A fresh PAMP or Valcambi bar typically delivers the same gold content at a slightly lower carrying premium than a secondary-market Credit Suisse bar of the same size.

The Credit Suisse bar is defensible in three specific cases. The buyer wants the discontinued brand for inventory or estate-continuity reasons. The secondary-market supply is priced competitively against PAMP for the requested size. Or the dealer is offering an authenticated Credit Suisse lot at a clearance discount.

The authentication chain depositories require for Credit Suisse bars

Because Credit Suisse branded bars are no longer being struck, the counterfeit risk is materially higher than for an in-production bar. Tungsten-cored fake Credit Suisse 1 oz bars have circulated since at least the early 2010s. One well-publicized case at a New York jewelry district refiner uncovered a multi-bar fake lot.

The FBI and the Better Business Bureau have issued periodic alerts on fake Swiss gold bars in general. Credit Suisse and PAMP product are over-represented in the alerts because of their high visibility in the resale market.

IRS-approved depositories that book secondary-market Credit Suisse bars run the same intake protocol they use on PAMP and Valcambi bars, then add three Credit Suisse-specific checks. The bar must arrive in the original Credit Suisse tamper-evident assay card with a serial number matching the bar face and the card. The card serial must be readable and the blister must show no signs of resealing. The Valcambi cross-and-shield mark on the bar reverse must be visible and undamaged.

For bars that arrive outside the original card (because the seller opened the card or the card was lost in transit), depositories typically reject the bar outright on first intake. A custodian may authorize a third-party authentication step at the dealer’s expense. The standard battery is ultrasonic density, X-ray fluorescence assay, and electromagnetic conductivity. The testing service then re-packages the bar into a new tamper-evident slab.

That re-authenticated bar can be booked into IRA custody. It carries a permanent buy-back discount on eventual liquidation because the original assay chain is broken.

The depository’s rejection of a non-conforming Credit Suisse bar is not an IRS rule per se. It is a depository risk-control rule designed to protect the segregated-storage chain from a substitution dispute at eventual liquidation. A rejected shipment delays the trade settlement and can leave the IRA owner exposed to a gold price move during the gap. SEC investor education on precious metals notes that authentication friction is a recurring cost factor for any discontinued or scarce bullion product.

For a first-time IRA buyer placing a Credit Suisse order, three questions need a documented answer from the dealer at the time of order. How was the bar lot sourced? Is each bar in original sealed Credit Suisse packaging? What is the dealer’s policy on the cost of third-party authentication if the depository raises a question on intake?

A dealer that cannot answer all three should not be the wire-recipient.

Acquisition flow from a secondary-market dealer to an IRS-approved depository

An IRA owner cannot take physical possession of Credit Suisse bars owned inside the IRA. Direct possession triggers a deemed distribution under IRC §408(m). The entire metal value is taxed as ordinary income in the year of receipt. If the owner is under age 59 1/2, a 10 percent early-distribution penalty applies under IRC §408(d). The bars must flow from the dealer directly to an IRS-approved depository titled in the name of the self-directed IRA custodian.

The procedural chain has five steps documented in the IRA transaction file. First, the IRA owner opens a self-directed IRA with a custodian that supports precious metals. A standard brokerage IRA cannot hold physical metals; a self-directed custodian is required.

Second, the IRA is funded by rollover, trustee-to-trustee transfer, or new contribution. Third, the IRA owner directs the custodian to place a specific Credit Suisse bar order with an approved dealer. The order specifies refiner (Credit Suisse), size, quantity, and the dealer’s commitment to deliver bars in original sealed Credit Suisse packaging.

Fourth, the custodian wires settlement funds to the dealer under the trust title of the IRA. The custodian then instructs the dealer to ship the bars directly to the IRA depository of record. Fifth, the depository receives the bars, runs the standard intake protocol plus the Credit Suisse-specific authentication checks described above, then books the bars into the IRA account under either segregated or commingled storage per IRS Publication 590-A custody rules.

Dealer selection at step three is where the IRA buyer’s largest variable cost lives on a Credit Suisse order. The dealer’s markup over spot, posture on authentication risk, and complaint history all attach to the trade. Vet the chosen dealer against the 2026 OPRS verdicts before authorizing the custodian to wire payment.

The operators that concentrate state-AG and CFTC enforcement actions also concentrate the wide-markup pushes this article frames against. A discontinued-brand secondary-market trade is exactly the context where those pushes tend to surface.

Storage at the depository: segregated versus commingled for Credit Suisse bars

IRS-approved depositories hold IRA metals under one of two arrangements. Segregated storage means the specific bars purchased for the account are held in a separately tagged compartment under the IRA name, with the bar serial numbers logged to the account. Commingled storage means the bars are pooled with other clients’ bars of the same specification, and the IRA holds a claim on an equivalent weight.

For Credit Suisse bars, segregated storage is the strongly preferred default, more so than for fungible bullion coins. The reason is that the bar serial number is the only authentication trace back to the original Valcambi production batch and the Credit Suisse assay card.

A commingled arrangement on a discontinued brand introduces two real risks. An eventual swap-out at distribution may deliver a different Credit Suisse bar with weaker provenance. Or the depository runs out of matching Credit Suisse inventory and substitutes a PAMP or Valcambi bar of equivalent weight and fineness.

Industry-reported segregated storage fees for Credit Suisse bars typically run 0.5 to 1.0 percent of asset value per year, or a flat $150 to $250 annual fee on smaller accounts. Commingled storage fees typically sit 25 to 40 percent lower but trade away the serial-number trace and accept the substitution risk.

The IRA owner’s segregated-versus-commingled preference is set at the time of order and rarely changes during the account life. An attempt to move bars between depositories without custodian-mediated transfer paperwork risks a deemed distribution under IRC §408(m). The depository-to-depository transfer must run through the self-directed custodian, who handles the paperwork and the chain-of-custody documentation.

Four mistakes that erode value on a Credit Suisse IRA order

• Accepting a Credit Suisse bar outside its original sealed assay card. An opened or re-blistered card breaks the authentication chain. The depository will either reject the bar on intake or require third-party authentication at the buyer’s expense, with a permanent buy-back discount on eventual liquidation. Correction: at order time, require the dealer to confirm in writing that every bar in the lot ships in its original sealed Credit Suisse card with a card-to-bar serial-number match.
• Paying a “Credit Suisse rarity” or “collector edition” premium for a retirement account. Credit Suisse never struck numismatic gold; the bars are bullion product with a small minted-bar premium and a discontinued-brand sourcing premium. A dealer presenting a Credit Suisse bar as “rare,” “graded,” “appreciating beyond bullion,” or “limited mintage” is mispricing the bar. Correction: pay no more than the published industry-reported premium band for the size and condition. Check the 2026 OPRS dealer list for the operators that concentrate the rare-Swiss-bar sales pattern.
• Ordering sub-ounce Credit Suisse bars (1 g to 10 g) for an IRA position. The per-ounce premium on Credit Suisse gram bars in 2026 runs roughly 9 to 20 percent over spot, versus 2.5 to 4.5 percent on a kilo bar. The gram bars trade on retail and gifting demand, not on retirement-allocation efficiency. Correction: order the largest Credit Suisse bar size that the dealer can source for the funding amount. A $30,000 order is typically one 100 g bar plus a top-up; a $60,000 order is typically one 1 kilo bar.
• Asking the dealer to ship the bars to the IRA owner’s home first to “verify” them. Physical receipt by the IRA owner is a deemed distribution under IRC §408(m), with full ordinary-income tax on the metal value plus a 10 percent penalty under age 59 1/2. Correction: the custodian directs the dealer to ship directly to the IRA depository of record, which runs the authentication intake. The IRA owner never touches the bars.

How Credit Suisse bars compare with PAMP Suisse, Valcambi, and Royal Canadian Mint bars

Credit Suisse is not the only LBMA-accredited refiner whose bars are IRA-eligible. The trade-offs against the major in-production alternatives are worth understanding before placing a Credit Suisse-specific order. All four product families are .9999 fine gold, all four are LBMA Good Delivery accredited, and all four are routinely accepted by U.S. self-directed IRA depositories.

PAMP Suisse bars (still in production) carry a roughly 1 percentage point lower premium on the 1 oz size than secondary-market Credit Suisse bars in 2026. PAMP’s CertiPAMP sealed-card format is the depository standard reference, and the LBMA Good Delivery referee status that PAMP holds adds a small but real liquidity edge at resale.

Valcambi Suisse bars (still in production, the same refinery that produced Credit Suisse bars under contract) carry similar premiums to PAMP at the 1 oz size. The Valcambi CombiBar (a divisible bar where small segments break apart for retail divisibility) is not typically used in IRAs because the divisibility feature is irrelevant when the bar is held inside a custody account.

Royal Canadian Mint gold bars (still in production) trade at premiums close to PAMP at the larger sizes. They carry the embedded DNA Anti-Counterfeit feature, a microscopic mint mark verified by RCM-licensed dealers. The RCM bar is the easiest of the four to authenticate after the fact, which makes it the lowest-friction choice for buyers who care about future re-verification.

For an IRA order in 2026, a buyer with no specific reason to prefer the Credit Suisse brand typically benefits from ordering a PAMP, Valcambi, or RCM bar instead. The in-production refiners deliver equivalent eligibility, lower authentication friction, and slightly lower carrying premiums.

A buyer who specifically wants Credit Suisse may have good reasons: existing inventory continuity, estate-planning preferences, or a dealer offering an authenticated lot at a clearance discount. The order should still run through a custodian-mediated chain with the documented intake protocol described above.

Are pre-merger Credit Suisse 100 g bars still IRA-eligible after the UBS acquisition?

Yes. The UBS acquisition of Credit Suisse closed in mid-2023 and ended new Credit Suisse-branded bar production. Bars produced before that date remain IRA-eligible under IRC §408(m)(3)(A) because the statutory test is purity plus refiner credential, not brand continuity. The Valcambi refiner credential is unchanged.

The merger has no impact on eligibility, but it has driven a real increase in counterfeit risk for any unsealed or out-of-card secondary-market Credit Suisse bar. Depositories have responded by tightening intake checks. Buyers should expect a Credit Suisse order to take longer to settle than an equivalent PAMP order while the depository runs the additional authentication checks.

What is the difference between a Credit Suisse bar and a Valcambi bar?

The two bars share the same refiner. Valcambi SA in Balerna, Switzerland, has produced both bar families since the early 1980s, with the Credit Suisse line struck under contract for Credit Suisse’s precious metals distribution business. The bar metallurgy, fineness, and Valcambi production hallmarks are identical; only the obverse branding differs.

The two product lines trade at similar premiums on the 1 oz and 100 g sizes in 2026, with Valcambi bars (still in production) typically carrying a slightly lower premium than secondary-market Credit Suisse bars of the same size. For a buyer with no brand preference, the Valcambi-branded bar is the lower-cost equivalent. For a buyer who specifically wants the Credit Suisse aesthetic or estate-continuity match, the secondary-market premium is the trade-off.

For a first-time IRA buyer about to order Credit Suisse bars on the secondary market, four elements need to be settled before the wire authorizing the trade.

1. The dealer’s sourcing chain for the specific lot. Where did the bars come from, are they in original sealed Credit Suisse cards, and what is the dealer’s authentication policy if the depository raises a question on intake.
2. The bar size mix. Default to the largest size the dealer can source for the funding amount, with smaller bars added only if a specific reason exists.
3. The depository preference for segregated versus commingled storage. Segregated is the strong default for a discontinued-brand bar, given the serial-number authentication trace.
4. The dealer’s BBB record and public complaint history.

Augusta Precious Metals publishes a free company comparison checklist that walks through the dealer-vetting criteria relevant to a secondary-market bullion bar order. Augusta operates with salaried, non-commissioned educators on the call under its published Education-First approach (Learn, Talk, Decide). It holds BBB A+ accreditation since 2014 with no complaints on file at the BBB.

Augusta was named Money Magazine’s Best Overall Gold IRA Company every year from 2022 through 2026. It was also Investopedia’s Most Transparent Gold IRA Company from 2022 through 2026. Augusta’s industry-reported minimum sits at around $50,000 for gold IRA accounts. If a smaller initial position is the goal, the comparison checklist lists alternatives with lower thresholds.
