What matters now
- Two separate CFR Title 12 parts are both nicknamed 'Regulation D.'
- Part 204 (Federal Reserve, Chapter II) covers reserve requirements for depository institutions.
- Part 1004 (CFPB, Chapter X) covers alternative mortgage transaction parity.
- The chapter number, not the shared nickname, is what tells the two apart.
Two different federal rules share the nickname “Regulation D.” One is “Part 204—Reserve Requirements of Depository Institutions (Regulation D)”, issued under “Chapter II—Federal Reserve System” of Title 12. The other is “Part 1004—Alternative Mortgage Transaction Parity (Regulation D)”, issued under “Chapter X—Consumer Financial Protection Bureau” of Title 12. The chapter number, not the shared letter “D,” is what tells a reader which one a given page is talking about.

Key points
- Two separate parts of Title 12 of the Code of Federal Regulations are both nicknamed “Regulation D” (Part 204; Part 1004).
- Part 204, under Chapter II (Federal Reserve System), covers reserve requirements for depository institutions (Part 204).
- Part 1004, under Chapter X (Consumer Financial Protection Bureau), covers alternative mortgage transaction parity (Part 1004).
- The chapter number — not the shared nickname — is what tells the two apart (Part 204; Part 1004).
The Federal Reserve’s Regulation D
The Code of Federal Regulations lists this rule as “Part 204—Reserve Requirements of Depository Institutions (Regulation D)”. It is placed within “Chapter II—Federal Reserve System” of Title 12, meaning the Federal Reserve System is the issuing agency.
The CFPB’s Regulation D
A second, unrelated rule is listed as “Part 1004—Alternative Mortgage Transaction Parity (Regulation D)”. It falls within “Chapter X—Consumer Financial Protection Bureau” of Title 12, meaning the Consumer Financial Protection Bureau is the issuing agency.
How to tell them apart
Both rules are Title 12 parts carrying the identical parenthetical “(Regulation D).” The nickname alone does not distinguish them. If a document or citation instead names the chapter or the issuing agency alongside “Regulation D,” that detail is what disambiguates it — Chapter II points to the Federal Reserve’s rule, Chapter X to the CFPB’s.
What this article does not cover
This article answers only which record each “Regulation D” is and which agency issued it. It does not describe what Part 204 currently requires of any institution or transaction — this piece confirms only the part’s title and its place in the CFR structure, not its operative substantive text, and it does not assert operative requirements from either part.
