The London Interbank Offered Rate (“LIBOR”) is a widely used benchmark for determining interest rates on various financial products. LIBOR is used to help set the rates on derivatives, bonds, commercial loans, student loans, mortgages, and various other financial products. LIBOR is calculated by the ICE (“Intercontinental Exchange”) Benchmark Administration (“IBA”) based on the anticipated cost of short-term borrowing from a panel of global banks.

BSBY is a proprietary index administered by Bloomberg Index Services Limited. BSBY measures the average yields at which systemically important banks access USD unsecured wholesale funding. It is a forward-looking term rate with credit sensitivity, reflecting marginal funding cost at overnight, 1-month, 3-month, 6-month and 12-month tenors. BSBY was created to meet client needs primarily in the US lending markets and complements the adoption of SOFR as the market moves away from LIBOR.

In July 2017, the Financial Conduct Authority (“FCA”), the regulator of LIBOR, announced that it will no longer require panel banks to submit rates for the calculation of LIBOR after 2021. Several panel banks have already stopped providing LIBOR submissions, making LIBOR unstable and less representative of the whole market it is intended to represent.

The FCA later confirmed that LIBOR will either cease to be provided by administrators or will no longer be representative of underlying markets. These events were in part the result of accusations that several large banks manipulated their LIBOR data submissions. Today, bank regulators and financial institutions across the globe, including East West Bank, continue to execute their plans for the transition to a new benchmark rate.

East West Bank continues to monitor industry developments regarding the anticipated discontinuance of LIBOR. We have created a cross-functional team to facilitate the LIBOR transition with our customers and partners.

U.S. regulatory agencies, including the Federal Reserve Bank (East West Bank’s prudential regulator) have issued guidance for banks to cease new contracts using U.S. LIBOR as a reference rate by December 31, 2021. East West Bank will act in accordance with this guidance.

Due to the lack of necessary input data to calculate U.S. LIBOR, the ICE Benchmark Administration (“IBA”) stated that it would cease publication of the seven U.S. LIBOR settings after the following dates:

U.S. LIBOR Settings Cessation Date:
December 31, 2021
Overnight/Spot Next
June 30, 2023

Existing LIBOR Loans and Related Products

It is important that all our customers are informed of this global market change. If you have an existing impacted product with East West Bank, we will contact you with details specific to your product prior to the cessation of LIBOR. Financial products with one-week and two- month tenors will be transitioned prior to the end of 2021. All other tenors will be transitioned prior to June 30, 2023. Most existing LIBOR products will transition to a variation of SOFR.

For existing hedged loans with a swap, cap, floor, collar, etc., your hedging agreement will also need to be amended. This can be accomplished by adhering to the International Swaps and Derivatives Association, Inc.’s (“ISDA”) 2020 IBOR (“Interbank Offered Rates”) Fallbacks Protocol, which incorporates fallback language for a replacement index and spread adjustment. East West Bank has already adhered to the Protocol.

You should consider its impact on your own business—but only after consulting with your own legal, tax, financing, and accounting advisors. New hedged loans will incorporate fallback language in the hedging agreement by adhering to the ISDA 2020 IBOR Fallbacks Supplement. Information on ISDA’s 2020 IBOR Fallbacks Supplement and Fallbacks Protocol can be found here

New Loans and Related Products

East West Bank now offers new loans using selected ARRs, including variations of SOFR and BSBY. These loans can also be hedged. To comply with regulatory guidance, East West Bank no longer offers LIBOR-based products. 

East West Bank has evaluated several potential alternative reference rates (“ARR”) including Prime, Treasury Rates, the Secured Overnight Financing Rate (“SOFR”), and the Bloomberg Short-Term Bank Yield Index (“BSBY”). While SOFR is expected to replace U.S. LIBOR for most financial products, suitable ARRs may depend on the type of loan or financial instrument, and the LIBOR tenor in use for existing loans and financial instruments. We will determine the best ARR for each impacted product and contact our customers to facilitate the transition. Whichever ARR is chosen, an appropriate spread adjustment will likely be required to align with existing LIBOR rates. 

If you have additional questions or concerns regarding this process, your East West Bank Relationship Manager is always available to ensure you have the information you need during this transition.

SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities in the repurchase agreement (repo) market. SOFR differs from LIBOR in two key respects: SOFR is a single overnight rate while LIBOR includes rates of several tenors; and SOFR is deemed a credit risk-free rate while LIBOR incorporates an evaluation of credit risk. Additionally, SOFR is based on historical transactions whereas LIBOR is based on “expert judgment” from the panel banks.

There are several variations of SOFR depending how interest is computed and if the rate is determined in advance or in arrears. There is a daily simple SOFR in arrears, a compounded SOFR in arrears, and a compounded SOFR in advance (with the latter published as SOFR Average by the Federal Reserve Bank of New York). There are also forward-looking term SOFRs which are based on market expectations implied from the SOFR derivatives market and are available in 1-month, 3-month, 6-month and 12-month tenors.
