I have added a new article to FinoLib, my finance education website: Head of Regulatory Capital and Head of Investment Management, part of Volume IV: Finance Careers. This page gives you the core of the topic in expert but plain language; the full article goes much deeper.
C.15 The Head of Regulatory Capital & Reporting
The idea in plain words
A bank is allowed to grow only as far as its capital allows. The Head of Regulatory Capital and Reporting turns every exposure the bank has into risk-weighted assets, meaning each loan or holding is counted by how risky it is. Then they report the capital ratios to regulators. That ratio caps how far the bank can grow, pay dividends or buy back its own shares.
Key points
■RWA = exposure × credit conversion factor × risk weight, plus market-risk RWA.
■US minimums: 4.5% CET1, 6% Tier 1, 8% total capital, plus buffers.
■Each new $2bn corporate loan needs about $150m of CET1 at a 7.5% requirement.
A closer look
This role owns the bank’s regulatory capital calculations and the regulatory submissions that follow from them. Basel III, the global standard set by the Basel Committee on Banking Supervision, reaches US banks through the capital rules of the Federal Reserve, the OCC and the FDIC: every exposure is converted into risk-weighted assets (RWA), and capital divided by RWA gives ratios that must stay above minimums plus buffers. Few other firm types hold capital against risk-weighted assets in this formulaic way, so the function is centered on banks and bank-like lenders such as India’s NBFCs.
A worked example
Worked Example: From Exposure to CET1 Ratio
Under the US standardized approach the build runs in four steps: map each exposure to its regulatory category, convert off-balance-sheet items into exposure with a credit conversion factor (CCF), multiply by the risk weight the rule assigns, then add market-risk RWA and divide common equity tier 1 (CET1) capital by the total. An illustrative bank: Exposure Amount CCF Risk weight RWA US Treasuries $20.0bn n/a 0% $0 Qualifying first-lien residential mortgages $30.0bn n/a 50% $15.0bn Corporate loans $40.0bn n/a 100% $40.0bn Undrawn corporate commitments, original maturity over one year $10.0bn 50% 100% $5.0bn Market-risk RWA from the trading book (given) $6.0bn Total RWA $66.0bn CET1 ratio = CET1 capital ÷ RWA = $7.5bn ÷ $66.0bn = 11.36%.
Why It Matters
A bank’s ability to grow its balance sheet at all is directly capped by its capital ratio — this function isn’t simply a reporting exercise, it’s one of the tightest real constraints on the CFO’s strategic options at any given moment.
Recap
The Head of Regulatory Capital turns every exposure into risk-weighted assets and reports ratios. US minimums are 4.5% CET1, 6% Tier 1 and 8% total capital, plus buffers.
C.16 The Head of Investment Management
The idea in plain words
An insurer collects money now and pays claims years later, so someone must invest it wisely. The Head of Investment Management, often called the CIO, invests the portfolio to match the length and timing of the policy promises. They typically report to the CEO and work within an investment policy statement, or IPS, approved by the board’s investment committee.
Key points
■The duration gap is D_A − (L ÷ A) × D_L.
■A negative gap means falling rates shrink surplus.
■The ALM report goes monthly to the CFO and quarterly to the investment committee.
A closer look
This role, often titled Chief Investment Officer (CIO), manages the insurer’s investment portfolio, often the company’s single largest asset, matched deliberately in duration and cash flow against the policy liabilities the Chief Actuary estimates (C.11: The Chief Actuary). Its core report is the asset-liability management (ALM) report, and its rulebook is the investment policy statement (IPS) that the board’s investment committee approves.
A worked example
Worked Example: The Duration Gap in the ALM Report
The ALM report shows how much the assets and the liabilities move when interest rates move. Its key line is the duration gap, using modified durations: DGAP = D_A − (L ÷ A) × D_L. An illustrative life insurer: Item Value Assets at market value (A) $12.0bn, duration 6.5 Liabilities, present value of policy cash flows (L) $10.5bn, duration 8.0 Surplus (A − L) $1.5bn Gap: 6.5 − (10.5 ÷ 12.0) × 8.0 = 6.5 − 7.0 = −0.5 years.
Recap
Fund Accounting (C.12: The Head of Fund Accounting) strikes and checks NAV, and Portfolio Valuation (C.13: The Head of Portfolio Valuation) defends Level 3 marks before a valuation committee. The Chief Compliance Officer (C.14: The Chief Compliance Officer) tests the firm’s conduct from outside finance, Regulatory Capital and Reporting (C.15: The Head of Regulatory Capital & Reporting) turns exposures into RWA and capital ratios, and Investment Management (C.16: The Head…
