About this family — the IDMD lineage

The Reserve Bank's Internal Debt Management Department (IDMD) runs the Government of India's borrowing programme as its debt manager — issuance and auctions of dated Government Securities, Treasury Bills and State Development Loans, and oversight of the Primary Dealer system. Reference numbers beginning IDMD mark documents from this department. Relief & Savings Bonds (the CO.DT series): also folded into this family is the legacy CO.DT Central-Office public-debt reference series — instructions to agency banks on servicing the Government's retail debt instruments such as Relief Bonds and Savings Bonds (interest payment, redemption and agency commission). We map these public-debt-servicing circulars here because they sit within the same internal-debt-management function. Related government-banking operations appear under Government & Bank Accounts, and market-side G-Sec / money-market regulation under Financial Markets Regulation. This is our plain-English overview; every document below links to its official page on rbi.org.in — we never reproduce RBI text verbatim. under the editorial review of Vikram Jain.

What this family governs

In plain English: the Internal Debt Management Department (IDMD) runs the RBI’s job as debt manager to the government — it issues government securities (G-Secs), Treasury Bills and State Development Loans, conducts the auctions through which they are sold, and oversees the Primary Dealers who underwrite them. This is the issuance of government debt, distinct from the regulation of how those securities then trade in the market (which sits under Financial Markets Regulation) and from day-to-day government banking accounts (under Government & Bank Accounts).

How to find the governing Master Direction for a circular

A quick four-step method to trace any Internal Debt Management circular back to its consolidated RBI rulebook.

  1. Read the RBI reference number
    Every RBI circular carries a reference number such as RBI/2023-24/108 with a department token such as IDMD. The letters before the first slash identify the issuing department.
  2. Match the department code to its family
    That department token maps to the Internal Debt Management family on this page. Legacy codes are folded into their modern department, so even older circulars resolve to the right rulebook.
  3. Open the consolidated Master Direction anchor
    In the Master Direction & Master Circular anchors list below, pick the consolidated rulebook for this family — it is the living document the individual circular amends or sits under.
  4. Verify on the official RBI source
    Follow the rbi.org.in link on the anchor or the circular to confirm the current text on the Reserve Bank's own website. BankPulse never reproduces RBI text verbatim.

Which RBI department issues government securities?
Government securities in India are issued by the Reserve Bank’s Internal Debt Management Department (IDMD), which acts as the debt manager for the Government of India. IDMD runs the issuance and auctions of dated Government Securities (G-Secs), Treasury Bills and State Development Loans, and oversees the Primary Dealer system that underwrites and makes markets in them. How these securities then trade in the secondary market is regulated separately under Financial Markets Regulation, and the government’s banking transactions sit under Government & Bank Accounts. Methodology reviewed by Vikram Jain; BankPulse is an independent platform, not affiliated with the Reserve Bank of India.
What is the difference between CRR and SLR?
CRR and SLR are the two reserve requirements the Reserve Bank uses to set aside a portion of a bank’s deposits, but they work differently. CRR (Cash Reserve Ratio) is the share of a bank’s net demand and time liabilities (NDTL) that it must hold as cash balances with the RBI; it earns no interest and cannot be used by the bank for lending or investment, so it is a pure monetary-policy and liquidity tool. SLR (Statutory Liquidity Ratio) is the share of NDTL that a bank must keep in specified liquid assets — chiefly Government Securities, along with cash and gold — which the bank continues to own and which can earn a return; these are largely the dated G-Secs and Treasury Bills issued through the RBI’s Internal Debt Management Department. In short, CRR is cash parked with the RBI that earns nothing, while SLR is mostly government bonds the bank holds itself and earns interest on; the RBI sets both ratios under the Banking Regulation Act and the RBI Act and revises them from time to time through the circulars linked on this page. This is general information, not advice. Methodology reviewed by Vikram Jain; BankPulse is an independent platform, not affiliated with the Reserve Bank of India.
