Westpac plans SEC deregistration, keeps U.S. issuance

Westpac Banking Corporation plans to voluntarily deregister from the U.S. Securities and Exchange Commission by filing a Form 15F as early as May 2026.

Rhea-AI Filing Summary

Westpac Banking Corporation plans to voluntarily deregister from the U.S. Securities and Exchange Commission by filing a Form 15F as early as May 2026. Its U.S. reporting duties under Section 15(d) of the Exchange Act will be suspended upon filing, with termination expected about 90 days later.

Westpac cites changes in its funding mix, including strong household deposit growth that has lifted its deposit-to-loan ratio above 80% and deeper Australian domestic debt markets. The bank still intends to issue long-term U.S. dollar securities, including under Rule 144A and section 3(a)(2), in line with Australian peers, and will continue providing information for investors via its website.

Insights

Cross-border banking & regulatory disclosure analyst

Westpac plans to exit SEC registration while maintaining access to U.S. funding markets.

Westpac Banking Corporation intends to deregister from the SEC via Form 15F, ending its Exchange Act reporting around 90 days after filing. This shifts the bank away from full U.S. reporting while it continues operating as a foreign issuer in capital markets.

The rationale is a funding mix that relies more on household deposits, lifting the deposit-to-loan ratio above 80%, and stronger Australian domestic debt markets. These factors appear to reduce the strategic value of maintaining SEC registration relative to its compliance burden.

Westpac plans to keep issuing long-term U.S. dollar securities, including under Rule 144A and section 3(a)(2), aligning with Australian bank peers. Future disclosures through its website and non-SEC formats will be key for U.S. investors who previously relied on Exchange Act reports.

What did Westpac Banking Corporation (WBKCY) announce in this Form 6-K?

Westpac announced its intention to voluntarily deregister from the SEC by filing Form 15F as early as May 2026. This will end its U.S. Exchange Act reporting while it continues to access U.S. capital markets through other issuance formats and website disclosures.

When will Westpac’s U.S. reporting obligations under the Exchange Act end?

Westpac’s reporting obligations under Section 15(d) will be suspended upon filing Form 15F, planned as early as May 2026. Termination of these obligations is expected about 90 days after filing, subject to the usual Exchange Act deregistration framework and conditions described.

Why is Westpac Banking Corporation (WBKCY) choosing to deregister from the SEC?

Westpac cites the ongoing requirements associated with SEC registration and changes in its funding composition. Strong growth in household deposits has lifted its deposit-to-loan ratio above 80%, and Australia’s domestic debt markets have deepened, prompting a review of its U.S. dollar issuance format.

Will Westpac continue issuing securities in the U.S. after deregistering?

Yes. Westpac intends to continue issuing long-term securities in the U.S. market, including under Rule 144A and section 3(a)(2) of the Securities Act. It describes this approach as consistent with formats used by Australian bank peers active in U.S. dollar funding markets.

How will Westpac Banking Corporation provide information to investors after SEC deregistration?

Westpac states that it will continue to provide all required information for existing and future investors on its website. This means investors will rely more on company web disclosures and non-Exchange Act documentation rather than regular SEC filings like Form 20-F and Form 6-K.

What forward-looking statement risks does Westpac highlight in this report?

Westpac notes that statements about its plans to deregister and related expectations are forward-looking. It warns actual outcomes may differ materially due to various risks, including those described under “Risk factors” in its 2025 Form 20-F, and it assumes no duty to update such statements.

Westpac Banking Corporation (“Westpac”) today announced its intention to voluntarily deregister from the United States Securities and Exchange Commission (the “SEC”) by filing a Form 15F with the SEC as early as May 2026. Upon filing the Form 15F, Westpac’s reporting obligations under Section 15(d) of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”) will be suspended, with termination of those obligations expected to occur 90 days after filing.

Westpac is taking this step after careful consideration of the ongoing requirements associated with SEC registration and in light of changes in the bank’s funding composition. Strong growth in household deposits has lifted the bank’s deposit-to-loan ratio above 80% and Australia’s domestic debt markets have deepened. Together with strengthened risk management frameworks, these changes have allowed Westpac to review the format of its U.S. dollar issuance.

Going forward, the bank intends to continue to issue long-term securities in the U.S. market, including under Rule 144A and section 3(a)(2) of the United States Securities Act of 1933, as amended, consistent with the formats used by its Australian bank peers.

Westpac will continue to provide all required information for both existing and future investors on its website (https://www.westpac.com.au).
