Platinum ETFs: Liquid Exposure Without Storage
Platinum exchange-traded funds provide exposure to platinum prices without the logistics of buying, storing, and insuring physical metal. For investors who want to express the platinum investment thesis through a brokerage account, ETFs are the most practical vehicle.
The platinum ETF market is small compared to gold. GLD and IAU hold $60+ billion and $30+ billion in gold, respectively. The entire platinum ETF universe holds a fraction of that. This size difference has real implications for liquidity, trading costs, and institutional adoption.
PPLT: The Primary Platinum ETF
The abrdn Physical Platinum Shares ETF (PPLT) is the largest and most liquid platinum ETF available to US investors.
Key facts:
- Issuer: abrdn (formerly Aberdeen Standard Investments, formerly ETF Securities)
- Structure: Physically backed (each share represents approximately 1/10th of an ounce of platinum)
- Expense ratio: 0.60%
- Custodian: JPMorgan Chase Bank (London vaults)
- Exchange: NYSE Arca
- Inception: January 2010
PPLT holds physical platinum bars in LPPM-approved vaults in London. The trust publishes a daily bar list showing the serial numbers, weights, and brands of all bars held. This transparency provides assurance that the physical backing is real and auditable.
Trading Characteristics
PPLT’s average daily trading volume fluctuates but generally runs in the range of 50,000-200,000 shares per day. This is adequate for retail investors and small institutional positions but thin by gold ETF standards (GLD trades 5-10 million+ shares daily).
Bid-ask spreads on PPLT typically run $0.05-0.15 per share, which translates to roughly 0.05-0.15% of share price. During volatile markets or thin trading periods, spreads can widen to $0.20-0.30. Use limit orders rather than market orders to control execution costs.
PPLT can trade at a premium or discount to its net asset value (NAV). Premiums of 0.5-1.5% and discounts of similar magnitude occur periodically. Authorized participants (large institutions) can create or redeem shares against physical platinum to arbitrage the premium/discount, but the process is slower and less efficient than for gold ETFs due to platinum’s lower liquidity.
Expense Ratio Context
The 0.60% annual expense ratio is significantly higher than gold ETFs (GLD at 0.40%, IAU at 0.25%). This reflects the smaller scale of the platinum ETF, higher storage costs relative to AUM, and the niche nature of the product. Over a 5-year holding period, the cumulative drag is approximately 3%, which is meaningful but less than the round-trip cost of buying and selling physical platinum.
GraniteShares Platinum Trust (PLTM)
GraniteShares launched a competing physically-backed platinum ETF offering a lower expense ratio.
Key facts:
- Issuer: GraniteShares
- Structure: Physically backed
- Expense ratio: 0.50%
- Custodian: ICBC Standard Bank (London vaults)
- Exchange: NYSE Arca
PLTM’s lower expense ratio (0.50% vs 0.60%) provides a modest cost advantage over PPLT. However, PLTM’s AUM and trading volume are significantly lower, which means wider bid-ask spreads and a greater risk of NAV premium/discount divergence.
For buy-and-hold investors, the 10 basis point expense ratio advantage may be offset by wider trading spreads. For active traders, PPLT’s superior liquidity makes it the better choice despite the higher expense ratio.
International Platinum ETFs
Investors outside the US have additional options:
WisdomTree Physical Platinum (PHPT). Listed on the London Stock Exchange and several European exchanges. Physically backed, with competitive expense ratios. Denominated in USD but tradeable in local currencies on European exchanges. A solid option for European investors.
South African Platinum ETFs. The Johannesburg Stock Exchange lists several platinum ETFs and ETNs, including products from Standard Bank and Absa. These are denominated in South African rand, adding currency exposure for international investors but providing local-currency platinum exposure for South African residents.
Japanese Platinum ETFs. The Tokyo Stock Exchange lists platinum-linked ETFs and ETNs. Japan’s strong platinum jewelry culture supports retail interest in these products.
ETFs vs Physical Platinum
The choice between platinum ETFs and physical platinum involves tradeoffs.
ETF advantages:
- No storage or insurance costs beyond the expense ratio
- Instant liquidity during market hours
- Fractional exposure (buy any dollar amount)
- No counterfeiting risk
- Easy to include in standard brokerage accounts and most retirement plans
Physical advantages:
- No counterparty risk (you hold the metal directly)
- No annual expense ratio drag
- Not dependent on ETF issuer solvency or custodian reliability
- Privacy (no brokerage reporting until sale)
- Tangible asset outside the financial system
For positions under $10,000-15,000, ETFs are typically more practical. The expense ratio drag is modest in dollar terms, and the convenience of brokerage-account trading outweighs the benefits of physical ownership for smaller allocations.
For larger positions or investors who prioritize direct ownership, physical platinum coins and bars provide exposure without counterparty risk. Many investors use both: ETFs for tactical exposure and physical for core long-term positions.
ETFs vs Futures
NYMEX platinum futures (PL) offer another route to platinum price exposure. Futures are more capital-efficient (leveraged) and have tighter bid-ask spreads in active contracts. However, futures require active management (rolling contracts before expiration), margin maintenance, and carry contango costs in normal market conditions.
ETFs are simpler. No rolling, no margin calls, no expiration dates. For most investors, especially those holding for months or years, ETFs are the more practical choice. Futures suit active traders and institutions that need leveraged or short exposure.
Platinum ETFs vs Gold ETFs: A Liquidity Reality Check
The liquidity gap between platinum and gold ETFs is stark. Relevant comparisons:
| Metric | PPLT (Platinum) | GLD (Gold) |
|---|---|---|
| AUM | $1-2 billion | $60+ billion |
| Avg daily volume | 50,000-200,000 shares | 5-10 million shares |
| Bid-ask spread | $0.05-0.15 | $0.01-0.03 |
| Expense ratio | 0.60% | 0.40% |
This liquidity difference means platinum ETFs are not suitable for large institutional positions or high-frequency trading. A $10 million buy order in PPLT could move the price; the same order in GLD would be invisible. Retail investors and small institutions can trade PPLT comfortably, but position sizing should account for the potential difficulty of exiting quickly in stressed markets.
Tax Considerations
Platinum ETFs structured as grantor trusts (like PPLT) are taxed as collectibles for US federal tax purposes. Long-term capital gains are taxed at a maximum rate of 28%, higher than the 15-20% rate on most equities. This is the same tax treatment as physical platinum.
Holding platinum ETFs in a tax-advantaged account (IRA, Roth IRA) eliminates the collectibles tax issue. In a Roth IRA, gains are tax-free entirely. The tax arbitrage makes retirement accounts the most efficient vehicle for platinum ETF positions, where available.
Consult a tax professional for current guidance, as tax rules can change and individual circumstances vary.
Building a Position
For most investors implementing the platinum investment thesis:
- Open a position in PPLT for liquid, tradeable exposure.
- Dollar-cost average over 3-6 months to reduce timing risk.
- Use limit orders to control bid-ask spread costs.
- Consider holding in a tax-advantaged account if possible.
- Complement with physical platinum coins or bars for long-term, non-counterparty exposure.
Monitor ETF flows as a sentiment indicator. Sustained PPLT inflows suggest growing institutional interest in the platinum thesis. Outflows may signal shifting sentiment. PPLT’s daily holdings data is publicly available and provides a real-time view of physically-backed investment demand.
Frequently Asked Questions
What is the best platinum ETF?
PPLT (abrdn Physical Platinum Shares) is the most liquid and widely held platinum ETF for US investors. Its physically-backed structure, reasonable expense ratio (0.60%), and NYSE Arca listing make it the default choice. PLTM (GraniteShares) offers a lower expense ratio (0.50%) but with significantly less liquidity.
Is PPLT physically backed?
Yes. PPLT holds physical platinum bars in LPPM-approved London vaults custodied by JPMorgan Chase Bank. The trust publishes a daily bar list with serial numbers and weights. Each share represents approximately 1/10th of an ounce of platinum. Authorized participants can create and redeem shares against physical metal.
What are the fees on platinum ETFs?
PPLT charges 0.60% annually; PLTM charges 0.50%. These are deducted from the trust’s metal holdings, so no separate fee payment is required. Over 5 years, the cumulative cost is approximately 3.0% (PPLT) or 2.5% (PLTM), which compares favorably to the round-trip cost of buying and selling physical platinum through dealers.
Can I hold platinum ETFs in an IRA?
Yes. PPLT and PLTM can be held in standard brokerage IRAs, including Roth IRAs. This is different from holding physical platinum in an IRA, which requires a self-directed IRA with an approved depository. ETF-based platinum exposure in a Roth IRA is particularly tax-efficient, eliminating the 28% collectibles tax rate on gains.
How liquid is PPLT compared to gold ETFs?
PPLT trades roughly 50,000-200,000 shares daily versus GLD’s 5-10 million. Bid-ask spreads are $0.05-0.15 for PPLT versus $0.01-0.03 for GLD. For retail positions (under $100,000), PPLT’s liquidity is adequate. For larger positions, the thinner market requires patience and limit orders to achieve reasonable execution.
