Hi,Anyone heard about Libor Option Adjusted Spreads (LOAS) for Bond Futures?I’m familiar with the fact that one can measure which bond is CTD either by comparing the highest Implied Repo or Lowes Net basis. BUT: Is it possible to use some kind of OAS approach as well?If so - how is it calculated?Thanks,

I doubt that there's a way to figure out the CTD using LOAS. LOAS tells you the financing spread over the entire life of a bond. With futures, you only care about the financing spread to the delivery date.

OK, Thanks for the answer. Question: Anyone aware of ANY kind of OAS approach (Not necessary LOAS) as a tool to measure any potential arbitrage between the current CTD bond and the likelihood that the CTD will change? OR: Is this just a completely different thing?Related:I’m aware of the deliverable options in the deliverable basket like:Yield Shift Option- Yield increases (strictly above 6%) leads to longer duration bondsYield Spread Option- Increased bond price (relative) leads to swapping CTD New Auction Option- New bond's can be issued (auction) that are cheaper to deliverWildcard Option- CBT closes at 2 pm, the short has until 8 pm to choose deliverable option.- Short to buy the bond tail short if the market dips, and sell long if the market rallies Switching Option- After the last day of the futures trading, the deliverer has the option to deliver another bondThanks,
