The Basel III Endgame: Bank Regulation In A Post-SVB World | Steven Kelly

Episode Summary

Executive Summary: Stephen Kelly argued the Fed’s new capital proposal is a tough opening bid: higher risk-based capital for large banks, tighter stress tests, and less reliance on internal models, while leaving the enhanced SLR unchanged. He stressed the real fragility in 2023 was deposit runoff and clientele concentration, not unrealized bond losses alone, and said the main future risk is slower-moving credit stress, especially commercial real estate, rather than another SVB-style run.

Main Topics: New Fed bank capital proposal (Priority: 5/5): Barr’s preview signals roughly 2 percentage points more capital for banks over $100B, with tougher model use and stress-testing assumptions, but no change to the enhanced supplementary leverage ratio. What caused SVB, Signature, and First Republic (Priority: 5/5): Kelly argued the failures were driven primarily by deposit attrition and business-model concentration, while unrealized securities losses were visible beforehand and not the immediate trigger. Risk-based capital vs. leverage ratios (Priority: 4/5): The discussion distinguished between risk-weighted capital rules and non-risk-weighted backstops like the SLR/ESLR, explaining why reserves might be carved out but treasuries were not. Interest-rate risk in banking (Priority: 5/5): Kelly rejected the idea that banks hedge like trading books; instead, banks hedge through deposit franchises, depositor stickiness, and the economics of new lending. Deposits, money market funds, and reserve drain (Priority: 4/5): Rising rates and QT have pushed money out of deposits into money funds and reverse repo, making the system more fragile and reducing bank funding stability. Commercial real estate and future financial stability risk (Priority: 4/5): He sees the bigger next risk as a credit crunch from commercial real estate and small-bank pressure, not a system-wide Wall Street collapse. Long-term debt / Basel III endgame (Priority: 3/5): The interview covered possible requirements for more bail-inable debt and the broader Basel III endgame, with skepticism that debt substitution is as good as straightforward equity.

Key Arguments: Barr’s proposal is deliberately tough and likely an opening bid: it raises capital requirements for the largest banks by about 2 percentage points and tightens model reliance/stress testing. The most important 2023 banking failures were not caused by unrealized losses in isolation; they were caused by deposit runs and a lack of confidence in the business model’s ability to be recapitalized. Banks do not truly hedge interest-rate risk the way trading firms do; their real hedge is a stable deposit franchise and the ability to roll assets into new loans over time. Risk-weighted capital can miss obvious risks because the weighting system is man-made and can understate duration or interest-rate exposure in apparently “safe” assets. Reserves are very different from treasuries because reserves have no price risk; that is why excluding reserves from leverage rules was considered reasonable, while excluding treasuries permanently was more controversial. Held-to-maturity securities are especially tricky because forcing them into regulatory capital would unfairly penalize banks like BofA/JPM that pay very low deposit rates and can hold assets to maturity. The next likely stress point is not another sudden SVB-style event, but slower, broader pressure from commercial real estate, deposit competition, and weaker credit conditions at smaller banks. The Fed’s best tool for a future credit crunch may be rate cuts, but that only helps before assets turn toxic; once loans are impaired, monetary policy is less effective.

Data Points: Capital increase for large banks: ~2 percentage points - Barr’s preview of the new capital proposal for banks with $100B+ in assets Asset threshold discussed: $100 billion in assets and bigger - Banks targeted by the new capital proposal Minimum common equity tier 1: 4.5% - Baseline risk-based capital minimum referenced in the discussion G-SIB surcharge / buffer: 2.5% - Added buffer for globally systemically important banks Approximate total risk-based capital: 13%-15% - Rough capital levels for large banks depending on stress test results and surcharges SLR (supplementary leverage ratio): 3% - Non-risk-weighted capital-to-assets ratio for banks ESLR for G-SIBs: 5% - Enhanced supplementary leverage ratio at holding company level Depository-level ESLR: 6% - Higher leverage requirement at the depository institution level for the largest banks Treasury exemption in 2020: 1 year - Treasuries and reserves were temporarily exempted from the SLR during the COVID Treasury-market dislocation SVB hedged interest-rate risk: 12% hedged - Kelly cited SVB as largely unhedged despite some hedging activity Aggregate U.S. banking assets hedged with interest rate swaps: 6% - Cited from a paper referenced in the interview SVB held-to-maturity securities: Over $200 billion - Large HTM portfolio at Silicon Valley Bank SVB bond-loss peak: Q3 2022 - Kelly said unrealized bond losses peaked then and were lower by Q4 2022 SVB stock price mentioned: $280/share - He noted the stock traded near this level after public reporting of losses Citigroup unrealized losses: $30 billion - Example of large-bank unrealized securities losses that Kelly said would not necessarily become a problem absent runs Bank of America unrealized losses: Over $100 billion - Example used to show large banks can absorb or ignore losses because of stable deposit franchises Bank count in the U.S.: Almost 5,000 banks - Used to illustrate how many institutions exist and that some smaller-bank failures need not equal systemic crisis Credit unions in the U.S.: Almost 5,000 - Part of the broader point about financial system fragmentation Money market fund jump in March: A few hundred billion dollars - Described as inflows during the March bank stress episode Money parked at the Fed RRP: Over $100 billion every day - Money market funds can place large sums directly at the Fed Current reverse repo facility size: $1.8 trillion - Mentioned as the facility’s approximate size during the discussion Recent decline in reverse repo: Down about $300-$400 billion in about a month - Used to explain shifts in liquidity between the RRP and the Treasury/banking system Fed funds upper bound: 5.25% - The current policy rate at the time of the interview Deposit sensitivity example: 10 percentage points - Kelly used this to illustrate how much depositors may demand if rates rise very high

Pivotal Quotes: "Capital’s beautiful." — Stephen Kelly / host framing: Used when discussing why regulators emphasize capital as a loss-absorbing buffer "The real interest rate risk here is in the clientele, in the industry focus, in the regional focus." — Stephen Kelly: Summarizing why SVB, Signature, and First Republic were vulnerable "The moment it becomes a toxic asset, the Fed’s too late." — Stephen Kelly: Explaining the limits of rate cuts as a fix for commercial real estate or credit deterioration

Implications: Banks are safer than in February but more fragile than they look; tighter capital and less model reliance may help, yet deposit behavior and commercial real estate remain the real watchpoints. Expect more pressure on smaller banks and continued scrutiny of funding stability.
