What Is to Be Announced (TBA)?
Let me explain TBA to you directly: it stands for 'To Be Announced' and refers to a forward-settling process in the trading of mortgage-backed securities, or MBS. In this setup, pass-through securities from agencies like Freddie Mac, Fannie Mae, and Ginnie Mae get traded without revealing the exact security right away, which boosts liquidity in the market. The system works because it treats MBS pools as basically interchangeable, making trades simpler and helping mortgage lenders manage their risks effectively.
You agree on key details upfront—things like the issuer, maturity, and price—but the actual securities aren't specified until just 48 hours before settlement. Sure, this has its advantages, but it also comes with risks from counterparty default and market swings, so I advise handling these professionally.
Key Takeaways
- TBA, or 'to be announced,' involves trades of mortgage-backed securities without initially specifying the exact securities.
- The TBA market covers pass-through securities from Freddie Mac, Fannie Mae, and Ginnie Mae, enhancing overall MBS liquidity.
- There's counterparty default risk between trade execution and settlement, which can be reduced with collateral.
- TBA differs from TBD ('to be determined') but is often used interchangeably outside finance for pending info.
How TBA Works in Mortgage-Backed Securities
Think of a TBA as a contract where you agree to buy or sell an MBS on a set date, but it skips details like the pool number, number of pools, or exact transaction amount. An MBS is essentially a bond backed by mortgage loans—loans with similar features get bundled into pools, and those pools serve as collateral for the MBS.
Investors get interest and principal payments based on what borrowers pay on those mortgages, and these come monthly rather than semiannually. The Securities Industry and Financial Markets Association sets the settlement rules for these MBS-TBA trades. The reason this works is that the TBA market sees MBS pools as fairly interchangeable, which lets thousands of varied MBS get traded via just a few contract types, ramping up liquidity.
As a trader, you and the counterparty settle on parameters like issuer, maturity, coupon, price, par amount, and settlement date. Each agency pass-through security has its monthly settlement date, and you must swap pool info by 3 p.m. EST, 48 hours prior. Trades go in $1 million lots. Here's a fast fact for you: the TBA market ranks as the second most active secondary market, right after U.S. Treasuries.
Analyzing the Risks of TBA Trades
Because these are forward-settling deals, there's always the risk of counterparty default in the gap between executing the trade and settling it. In volatile markets, if one side defaults, the other might not find a comparable deal once it's obvious. You can cut this risk by assigning collateral to the trade, though not every firm has quick access to collateral services.
Back in January 2014, with average daily TBA trading volumes hitting over $186 billion, FINRA introduced margin requirements to lower risks for trades with longer settlement dates. This applies only to certain individuals or institutions and isn't needed for short-settlement deals.
Beyond Mortgage-Backed Securities: Alternate Uses of TBA
'To be announced' isn't just for bonds; in other contexts, it's often swapped with TBD, or 'to be determined.' If there's info coming up but the exact timing isn't set, it might show as TBA. For example, a company could plan its annual shareholders' meeting for spring next year, with the precise date and spot TBA until finalized.
You see it as a placeholder in shipping, logistics, news, or HR changes too—like hiring a new manager, with the candidate TBA after talks wrap up.
Does TBA Mean Something Different in Finance?
In bond trading, TBA specifically means trading certain mortgage-backed securities where details aren't announced until later. You agree on essentials like issuer, maturity, coupon, price, par amount, and settlement date, and the specific securities get revealed 48 hours before settlement.
What Is the Difference Between TBA and TBD?
Outside MBS, 'to be announced' and 'to be determined' get used the same way and mean similar things. Technically, TBA—a pending announcement—comes after something's been determined, so it follows TBD. Say a company is deciding on an acquisition—that's TBD. Once approved, it shifts to TBA until officially announced.
When Are MBS Trades Described As TBA?
A TBA trade is basically a contract to buy or sell MBS on a specific date, without including pool numbers, pool counts, or exact amounts, so the underlying mortgages stay unknown. This data skip happens because the TBA market assumes pools are interchangeable, aiding trading and liquidity.
The Bottom Line
The TBA market is key for making the MBS market more liquid and efficient by bundling similar loans into tradable contracts without detailed pool info upfront. These trades offer big upsides, like helping lenders hedge their pipelines, but they carry risks like counterparty default, especially in shaky markets. If you're in TBA trades, know these risks and consider collateral to handle potential defaults. Grasping how TBA works and its risks is vital if you're in the MBS space.
