Oil surged from around $71 to nearly $98 per barrel in under two weeks in early March 2026 as geopolitical tensions in the Persian Gulf tightened supply fears. That kind of move is exactly what crude oil investors dream about. It is also exactly the kind of move that ETRACS Crude Oil Shares Covered Call ETN (NASDAQ:USOI) is structurally designed to miss most of.

What USOI Is Actually Trying to Do
USOI is not a straightforward crude oil fund. It is an Exchange Traded Note, a senior unsecured debt obligation issued by UBS AG after migrating from Credit Suisse following that bank’s collapse. The ETN tracks the Nasdaq WTI Crude Oil FLOWS 106 Index, holding a notional long position in USO shares while selling monthly call options approximately 6% out-of-the-money out of the money. The premium collected from those calls gets distributed as monthly income.
That out-of-the-money cap defines the strategy. If United States Oil Fund (NYSEARCA:USO) rises more than 6% in a given month, the calls get exercised and USOI’s upside stops there. The fund explicitly trades away large price gains for consistent monthly cash flow. Investors who understand that tradeoff are the target audience. Those who don’t often end up frustrated.
The Covered Call Math in a Volatile Oil Market
WTI crude surged from $71 to nearly $98 per barrel between early March and mid-March 2026, one of the sharpest short-term oil moves in recent memory. A direct crude oil position captured nearly all of that gain, but USOI’s sold calls capped monthly upside at 6%, meaning the ETN participated in only the opening leg of the rally before the ceiling kicked in.
The current VIX reading of 25.09 is actually favorable for USOI’s income generation. Higher volatility inflates option premiums, meaning monthly distributions can be larger in environments like this one. The VIX has spiked as high as 52.33 in April 2025, a period that would have generated maximum premium income, though the underlying oil position would have been under stress simultaneously.
The ETN Structure Is a Risk Most Investors Overlook
An ETF holds actual assets in a trust legally separate from the fund manager. An ETN is a bond. If the issuer runs into serious trouble, ETN holders are unsecured creditors standing behind secured debtholders in a bankruptcy. USOI was originally issued by Credit Suisse, and when that bank collapsed in 2023, the product transferred to UBS AG. The migration worked out, but it illustrated exactly what counterparty risk means: your return depends not only on oil prices and option premiums, but on the continued solvency of the issuing bank. That risk has not disappeared under UBS ownership; it has simply shifted to a more stable counterparty.
Does It Deliver on Its Promise?
USOI has gained nearly 24% year-to-date and about 20% over the past year, respectable numbers that come alongside meaningful monthly income in high-volatility environments. The fund does what it says it does.
The honest comparison is what investors gave up. WTI crude climbed from around $75 in January 2025 to nearly $98 at its March 2026 peak — a move a direct crude position would have captured in full. USOI’s covered call overlay repeatedly capped monthly gains at 6%, meaning each sharp spike contributed far less to total return than the raw oil move would suggest.
That structural ceiling shows up clearly at the index level, where the underlying index shows a one-year return of -4.78% reflects how the covered call overlay works in practice: option premiums flow out as income distributions, reducing the price return investors see on paper. The total return picture only makes sense when those monthly payouts are added back in.
Three Realistic Tradeoffs
- Capped upside during oil spikes: The 6% monthly ceiling means that when geopolitical events drive crude sharply higher in a short window, as happened in March 2026, USOI captures only a fraction of that move.
- Counterparty credit risk: USOI’s value depends on UBS AG remaining solvent. In normal markets this is theoretical. In a financial crisis it becomes very real, and holders have no claim on underlying assets the way ETF investors do.
- Income volatility despite the income label: Monthly distributions fluctuate with oil volatility and option premium levels. When the VIX is low and oil is calm, premiums shrink and the income check gets smaller. Investors treating it like a bond coupon will be surprised by the variability.
USOI fits a narrow but real use case: income-focused investors who want crude oil exposure, accept they are permanently trading away large upside for monthly cash flow, and understand they are holding an unsecured bank note rather than a fund with segregated assets.
