Regulatory Capital Requirements under Banking Regulations [Abstract]

Regulatory matters

Regulatory matters

Payment of dividends by M&T’s banking subsidiaries is restricted by various legal and regulatory limitations. Dividends from any banking subsidiary to M&T are limited by the amount of earnings of the banking subsidiary in the current year and the preceding two years. For purposes of this test, at December 31, 2024, approximately $2.3 billion was available for payment of dividends to M&T from banking subsidiaries. M&T may pay dividends and repurchase stock only in accordance with a capital plan that the Federal Reserve has not objected to.

Banking regulations prohibit extensions of credit by the subsidiary banks to M&T unless appropriately secured by assets. Securities of affiliates are not eligible as collateral for this purpose.

M&T and its subsidiary banks are required to comply with applicable Capital Rules. Failure to meet minimum capital requirements can result in certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a material effect on the Company’s financial statements. Pursuant to the rules in effect as of December 31, 2024, the required minimum and well capitalized capital ratios are as follows:

	Minimum		Well Capitalized
M&T (Consolidated)
CET1 capital to RWA	4.5	%
Tier 1 capital to RWA	6.0		6.0	%
Total capital to RWA	8.0		10.0
Leverage — Tier 1 capital to average total assets, as defined	4.0

	Minimum		Well Capitalized
Bank Subsidiaries
CET1 capital to RWA	4.5	%	6.5	%
Tier 1 capital to RWA	6.0		8.0
Total capital to RWA	8.0		10.0
Leverage — Tier 1 capital to average total assets, as defined	4.0		5.0

Capital regulations require buffers in addition to the minimum risk-based capital ratios noted above. M&T is subject to a SCB requirement that is determined through the Federal Reserve’s supervisory stress tests and M&T’s bank subsidiaries are subject to a 2.5% capital conservation buffer requirement. The buffer requirement must be composed entirely of CET1 capital. In June 2024, the Federal Reserve released the results of its most recent supervisory stress tests. Based on those results on October 1, 2024, M&T's SCB of 3.8% became effective. Accordingly, at December 31, 2024 M&T is subject to a CET1 capital requirement of 8.3% (a sum of the SCB and the minimum CET1 capital ratio).

The capital ratios and amounts of the Company and its banking subsidiaries as of December 31, 2024 and 2023 are presented below:
