Using Costless Collars to Hedge Interest Rate Risk
The NCUA’s May 2021 updates to 12 CFR §703.103 have empowered credit unions to use costless collars as a tool for managing interest rate risk. These strategies are permissible under the NCUA’s updated derivatives regulation and comply with GAAP (ASC 815), incorporating updates from ASU 2017-12, which optimizes hedge accounting. Costless collars offer a flexible, cost-effective strategy for stabilizing cash flows while managing operational challenges
The following analysis examines the use of costless collars to hedge interest rate risk on two specific use cases:
1) on assets in the form of adjustable-rate mortgages (“ARMs”) and
2) on liabilities in the form of Federal Home Loan Bank (“FHLB”) borrowings.
General Regulatory Framework: NCUA’s May 2021 Derivatives Rule Update
The May 2021 revisions to 12 CFR §703.103 modernized how federally insured credit unions use derivatives to manage interest rate risk. Key considerations include:
A. Principles-Based Approach: The NCUA removed prescriptive limitations on specific derivative instruments, allowing credit unions to deploy strategies such as costless collars if consistent with their risk management practices and priorities.
B. Risk Management Requirements:
a. Credit unions must establish board-approved policies outlining the purpose, scope, and limits for derivative use.
b. Robust internal controls are required to monitor and mitigate risks from derivative transactions.
C. Competency and Expertise:
a. Credit unions must demonstrate expertise in derivatives through qualified staff or external advisors.
b. Ongoing training and audits are necessary to ensure compliance with the framework.
D. Alignment with NCUA Goals: Derivatives must be used to manage risk in a safe and sound manner that supports the credit union’s strategic objectives, and not for speculative purposes, which is strictly prohibited.
Use Case 1: Asset Side – Hedging Interest Rate Risk on Adjustable-Rate Mortgages (ARMs)
Example scenario: a credit union holds a portfolio of 5/6 ARMs. These mortgages have a fixed rate for the first five years, after which they reset every 6 months based on the 30-day average SOFR rate plus a margin, depending on the loan agreements. Declining interest rates post-reset could reduce interest income and negatively impact the credit union’s Net Interest Margin.
Hedging Strategy
The credit union uses a costless collar:
• Buys an Interest Rate Floor: Protects against declining rates by ensuring a minimum yield on the ARM portfolio after reset.
• Sells an Interest Rate Cap: Offsets the purchased floor’s pr...
