Buying Bigger & Smaller Security Sized Quantities Can improve Yield, ROI, ROA, and Capital

Summary: We've analyzed just over 14,000 securities in detail worth over $17 billion in par value and found some very interesting things you can likely benefit from. We welcome the conversation about your specific situation and portfolio as we cannot share particulars in a general forum without a better knowledge of your institutions specific portfolio -- and there is a great deal to learn and share. In fact there is likely not a better advisor out there who has the cost control and yield improvement subject matter expertise in the Community Financial Institution marketplace. 


Up front and center. Buying Larger -- and counter-intuitively -- "Smaller" Odd-lot Security Sized Quantities can generally improve Yield, ROI, ROA, and Capital for very different reasons in many situations. A second is that the cost savings curves seem to differ by security type with Munis, Corporates, Agencies and MBSs having demonstrably different, what we call, affordability curves. Of course there can be hurdles on both sides of the continuum, and, every institution is different and requires it's own careful and specific analysis. Conducting a deep dive from a fiduciary can be an important cornerstone of enhanced due-diligence and portfolio oversight -- one we think should be considered every few years -- and especially independently after major market moves -- like the ones we are in the middle of. More eyes on a fast-moving situation can often uncover overlooked intricacies that can lead to unexpected benefits.

Some important generalities to consider include:

  • Buying Larger: Let's tackle buying units of $5-million, $2-million and even $1-million first. Generally speaking improvements in price, and thereby yield, can happen with larger blocks for many reasons including:
  • they are easier for the broader institutional market to move (i.e., sell),
  • there is often times unrealized margin in them to be unbundled into smaller units that can then be sold in less efficient markets in smaller chunks,

There are other potential advantages coming from larger blocks including:

  • the fewer cusips that an institution needs to manage can tend to help with oversight and regulatory compliance,
  • maintaining a research file of all securities is often less challenging when their are fewer cusips to track,
  • all things being equal, exception reporting and the potential for a credit debacle could be reduced,
  • the costs associated with safekeeping can be reduced

Disadvantages may exist too including: the potential for reduced diversity in the portfolio (especially for smaller community financial institutions) could become an issue with concentration risk in volatile markets with significant moves. For smaller institutions, buying in smaller round lots where possible may help with this specific disadvantage.

  • Buying Smaller and "Odd": Odd-lots" are exactly what they sound like. They are "odd" sizes and we have found can traditionally yield 3 to 5 bps more than larger quantities as many larger institutional investors do not like penciling what could be a large amounts of cusips to pick up a few basis points in additional yield. If HTM, your institution can reap the marginal benefits till the end. As one moves into the 'retail' realm where most trades are "odd-lots" (if not micro-"odd-lots") spreads can widen even more in a ever-greater generally inefficient buy/sell marketplace from the end-consumer perspective. Disadvantages include if an institution is forced to sell the "odd-lot" for other liquidity needs that are more desirable, or if the credit rating drops below an acceptable level unexpectedly as can happen. In these 'selling' scenarios the same tailwinds become headwinds and can lower the sale price of the "odd-lot" in question.

What is "odd" is oftentimes also dependent on the size of the institution with larger institutions who have greater security portfolio assets considering an CMO purchase under a million 'current' an odd-lot whereas as smaller institution with a smaller overall securities portfolio might consider a CMO under $500,000 'current' an odd-lot. Similarly CDs, Corporates, and other securities could be an odd-lot for the larger institution, but not the smaller institution.


Additionally, and this is where a detailed analysis is likely required, the amount charged by firms to financial institutions regardless of size, can differ wildly across asset classes of securities. We have generally rank ordered them below from what we have found to be most expensive to the most economical securities type to financial institutions in general as outlined in the summary above. Of course the added costs incurred within the bond usually do not out way the reason to purchase the specific asset class, but it's a fascinating analysis none-the-less for the most informed possible purchase decisions for an institution -- each security type with its own specific added cost curves, by size of security purchase, with some security types favoring smaller size purchases, others larger size purchases, and still one with middle-sizes purchases while staying away from the larger and smaller sizes.

There are likely reasons why your institution may not be shown some interesting Treasuries strategies right now – that is because they are just not as profitable for the institution selling to you. But that is the topic of the next From The Desk Of.
