Treasury basis trade

I have a couple of questions about the UST basis trade:

Is the basic strategy (long basis, hold to delivery or close to delivery) still a profitable strategy on the buy side, or have players gotten more sophisticated (e.g. taking directional views on the basis, etc)?
The classic long basis trade seems very easy, requiring virtually zero informational/modeling edge (please correct me if I'm wrong). Why doesn't every single hedge fund get involved? What am I missing?
How much of the trade is a view on delivery option fair value, and how much of it is just harvesting the futures premium due to real money demand for UST futures?
How does the repo part of the trade work? Is it mostly ON repo's? If so, how do you hedge financing rate risks (e.g. Sept 2019)? If term repo, are they matched to the delivery date of the bond? How much of a premium do dealers charge for that?
How much of the trade depends on having good relationships with dealers, and getting good conditions on repo? Is the trade open to any decently sized hedge fund, or does it depend on having massive rates flows (e.g. something open to ExodusPoint, Citadel, and a few others)?
Finally, do you see any structural headwinds or tailwinds for the trade in the future? How might regulatory changes impact the profitability of the trade?

Thank you!

The Treasury basis trade, while seemingly straightforward, involves several nuanced factors that influence its profitability and accessibility. Here's a breakdown of your questions based on the most helpful WSO content:

1. Profitability of the Basic Strategy (Long Basis, Hold to Delivery)

The classic long basis trade (buying the cash bond and selling the corresponding futures) can still be profitable, but the margins have compressed over time due to increased competition and sophistication among market participants. Many players now incorporate directional views on the basis, advanced modeling, and other strategies to enhance returns.
The simplicity of the trade (harvesting the futures premium) means it attracts significant attention, but profitability often depends on execution efficiency, financing costs, and the ability to manage risks like repo rates and delivery options.

2. Why Doesn't Every Hedge Fund Participate?

While the trade may appear simple, barriers to entry include:
- Repo Market Access: The trade requires reliable and cost-effective repo financing, which is not equally accessible to all funds.
- Execution Efficiency: Margins are thin, so execution costs (e.g., bid-ask spreads, slippage) can erode profitability.
- Capital Requirements: The trade involves significant leverage, requiring funds to have robust risk management and sufficient capital.
- Regulatory Constraints: Post-GFC regulations (e.g., Basel III) have increased the cost of holding and financing USTs, making the trade less attractive for some players.

3. Delivery Option Fair Value vs. Futures Premium

The trade is a mix of both:
- Delivery Option Fair Value: A portion of the trade involves assessing the fair value of the delivery option embedded in the futures contract. This requires modeling expertise and market insight.
- Futures Premium: The other component is harvesting the futures premium, driven by real money demand for UST futures (e.g., pension funds, insurance companies).

4. Repo Mechanics and Financing Rate Risks

Repo Usage: The trade typically involves overnight (ON) repos, but term repos are also used, especially when aligning financing with the bond's delivery date.
Hedging Financing Rate Risks: Funds hedge financing risks through:
- Diversifying repo counterparties to mitigate counterparty risk.
- Using interest rate derivatives (e.g., OIS swaps) to hedge against spikes in repo rates.
Dealer Premiums: Dealers may charge a premium for term repos, especially during periods of market stress or high demand for specific collateral.

5. Importance of Dealer Relationships

Strong relationships with dealers are critical for:
- Securing favorable repo terms.
- Accessing liquidity during market stress.
- Obtaining insights into market flows and conditions.
While the trade is theoretically open to any decently sized hedge fund, the best terms and execution are often reserved for funds with significant rates flows and established dealer relationships (e.g., ExodusPoint, Citadel).

6. Structural Headwinds/Tailwinds and Regulatory Impact

Headwinds:
- Regulatory changes (e.g., Basel III, leverage ratio requirements) have increased the cost of holding and financing USTs, potentially reducing profitability.
- Increased competition and tighter spreads make the trade less lucrative.
Tailwinds:
- Continued demand for USTs as high-quality collateral supports the repo market.
- Market volatility can create opportunities for skilled participants.
Future Regulatory Impact: Potential changes to repo market regulations or central clearing of USTs could impact the trade's dynamics, either by reducing financing costs or altering market structure.

In summary, while the Treasury basis trade remains a staple strategy, its profitability and accessibility depend on factors like repo market conditions, execution efficiency, and regulatory developments. It's not as "easy" as it seems, given the complexities of financing, risk management, and competition.

I get the feeling that you are either a strategist or a cash trader? Some of your questions have wrong assumptions so it’s hard to answer.
But to question 1, no, the alpha is getting leaner.

some thoughts based on my limited understanding:

Have heard that the basis trade has died out a bit recently. Lower long future demand from Asset managers and better intermediation capacity of dealers essentially made the trade less attractive for hedge funds. In essence, the attractiveness of the basis trade is a function of how constrained dealers are. But now that regulations have eased for dealers, the attractiveness has faded.
Don’t really have an answer to that. Maybe it is tied to specific expertise in that field that some hedge funds might have (like having explicit basis traders).
Again not sure, but would say that the trade is predicated on a particular view on the delivery option as one can essentially derive the net basis as the delivery option
Not quite sure how the breakdown is between ON Repo and term repo. Term repo probably would be derived based on the SOFR curve and would allow one to be aware of carry relative to rolling overnight repos while also not having the funding volatility potentially. However, could be more different to find a counterparty for term repos, not sure. Also term repos could lead to higher haircuts (which influence the leverage in basis trades).
Tied to 1).

Don't trade basis but have been at funds that do trade it so have small understanding.

Yes, the main question is the return on cash that the trade provides under reasonable repo assumptions. Funds are almost never net short basis, it's more about how much you have on at a given level based on the attractiveness of basis vs other balance sheet strategies (short end swap spreads, XCCY basis). The alpha in it has compressed a lot, for the reasons stated above plus a lot more funds able to do the trade in size.
Repo availability and haircut the main one. FIPB relationships aren't easy to spin up if you don't have them. You need serious capital and relationships (read "pay a lot") with the street. Your business dies if a bank pulls sheet from you in times of stress.
It's mainly a risk premia strategy and a question of optimal usage of your fund balance sheet. Not rocket science to value the CTD optionality.
Yes that's a risk, term repo more expensive but less painful in repo blowups (which eat your carry). Understanding the repo market and how to structure your financing are part of all bond RV strategies including basis.
