This put up is the second in a three-part collection on how financial institution regulation interacts with the organizational construction of banking corporations. The first put up documented that nonbank subsidiaries inside financial institution holding firms (BHCs) are giant, equity-rich “reservoirs,” and that bank-level capital diverged sharply from consolidated capital after Basel III took impact in 2015. This put up asks why, and traces the reply via the interior plumbing of the holding firm. The collection attracts on the authors’ current Workers Report, “Regulatory Arbitrage Inside the Agency.”
When Basel III’s binding capital minimums took impact for U.S. banks in January 2015, a financial institution holding firm (BHC) whose depository subsidiary fell in need of the brand new requirements had two choices. It may increase recent fairness in exterior markets, a pricey possibility. Or, if it owned equity-rich nonbank associates, it may merely transfer capital from one subsidiary to a different. The second route satisfies the regulator, avoids issuance prices, and leaves consolidated fairness precisely the place it was. On this second put up of our collection, we present that that is exactly what organizationally advanced BHCs did in response to increased capital necessities.
Extra Capital on the Financial institution, None on the Holding Firm
To determine variations in organizational complexity that predate Basel III, we exploit historic variation in interstate banking deregulation. States eliminated restrictions on interstate banking at totally different occasions in the course of the Nineteen Seventies, Eighties, and early Nineties. BHCs headquartered in states that deregulated earlier had extra time to broaden and construct advanced multi-subsidiary organizations earlier than interstate banking restrictions have been harmonized nationally in 1994. These historic variations strongly predict organizational complexity a long time later (as proven within the chart beneath), but they’re unlikely to be associated to Basel III implementation three a long time on. In keeping with this, early- and late-deregulating states present no divergence in nonbank exercise earlier than deregulation; the hole opens solely afterward.
Deregulation Timing as an Instrument for Organizational Complexity
Notes: The chart reveals the developments in nonbank monetary subsidiary share from 1986–1994, between BHCs headquartered in early-deregulating states and late-deregulating states. Early deregulators are outlined as states with median interstate deregulation 12 months earlier than 1986.
Utilizing this variation, we discover that banks in BHCs headquartered in states that deregulated one 12 months earlier accumulate about three-quarters of a share level extra extra capital after 2015. Given the roughly seven-year distinction between early and late deregulators in our pattern, this interprets to about 5 share factors extra extra capital on the financial institution stage. On the consolidated BHC stage, the corresponding estimate is basically zero. Consolidated property, lending, and leverage are likewise unchanged.
A big bank-level impact paired with a null consolidated impact helps rule out the external-issuance story; new fairness raised in markets would have lifted consolidated capital too. However we will additionally see the issuance margin immediately. BHCs with higher deregulation publicity considerably scale back exterior fairness issuance after 2015. Fairly than faucet markets to fulfill tighter necessities, advanced BHCs scale back their reliance on exterior buyers. That’s solely potential if capital is offered from elsewhere contained in the group.
Following the Cash, Step by Step
The holding firm’s personal unconsolidated filings allow us to observe fairness flows between mother or father and subsidiaries immediately, they usually reveal a clear three-step reallocation amongst BHCs with significant nonbank operations.
Step 1: The mother or father shifts fairness towards banks. After 2015, mother or father fairness investments in financial institution subsidiaries rise by 2.28 share factors of complete BHC fairness per 12 months of deregulation publicity, whereas investments in nonbank subsidiaries fall by an almost an identical 2.64 share factors. Complete mother or father investments throughout all subsidiaries are unchanged. The mother or father doesn’t inject extra capital into the group; it adjustments the place present capital sits inside it.
Step 2: The nonbanks provide the money. The place do the funds for these fairness injections come from? The reply seems in subsidiary dividend flows, proven within the desk beneath. Following Basel III, dividends flowing from nonbank subsidiaries to the mother or father improve sharply. Dividends from financial institution subsidiaries, against this, present little change. The mother or father successfully attracts sources from the less-regulated aspect of the group whereas leaving the regulated financial institution aspect largely untouched.

Notes: The desk presents reduced-form estimates of inside fairness reallocation inside BHCs. The dependent variable in column 1 is fairness investments in financial institution subsidiaries divided by complete BHC fairness. Column 2 is fairness investments in nonbank subsidiaries divided by BHC fairness. Column 3 is complete fairness investments in all subsidiaries divided by BHC fairness. Fairness investments embody frequent inventory, most well-liked inventory, goodwill, and different intangibles. Column 4 is quarterly dividends obtained by mother or father from financial institution subsidiaries divided by lagged fairness funding in banks. Column 5 is dividends from nonbank subsidiaries divided by lagged fairness funding in nonbanks. Years from deregulation measures years between BHC headquarters state’s interstate branching deregulation and 1994 Riegle-Neal Act. Submit signifies 2015:Q1 and later. All specs embody BHC mounted results and quarter-year mounted results. BHC controls embody prime 200 BHC indicator, log property, leverage, ROA, deposits/property, asset development, and subsidiary rely, all measured as of 2013:Q1 and interacted with put up. Normal errors clustered at BHC stage. Pattern restricted to BHCs with nonbank asset share exceeding 1 %.
*p<0.1, **p<0.05, ***p<0.01.
Step 3: Banks retain extra earnings. Fairly than distributing earnings upstream to the mother or father, banks more and more retain them. Amongst BHCs with nonbank subsidiaries, retained earnings at financial institution subsidiaries rise considerably after 2015. Banks with out entry to nonbank associates present no comparable change.
Collectively, mother or father fairness injections and elevated earnings retention account for the financial institution capital buildup documented above, even because the circulation of recent capital into the consolidated group declines. The cash by no means enters the group from exterior; it strikes inside.
The Significance of the Fairness Reservoir
The first put up on this collection launched the concept nonbank subsidiaries act as “fairness reservoirs” as a result of they maintain a disproportionately giant share of organizational fairness relative to their property. The scale of that reservoir is captured by the fairness multiplier: the nonbank share of consolidated fairness relative to its share of property, with bigger values indicating extra redeployable fairness to attract on.
If these reservoirs are what make inside reallocation potential, then the response to Basel III ought to scale with the multiplier: amongst BHCs that function each financial institution and nonbank subsidiaries, these with bigger reservoirs ought to shift extra fairness towards their banks. That’s precisely what we discover. Every extra unit of the 2013 fairness multiplier is related to a 1.71 share level bigger post-2015 improve within the share of consolidated fairness invested in banks, and a 1.12 share level bigger decline within the share invested in nonbanks.
The chart beneath reveals the identical relationship as a easy cross part. Every level is one BHC’s change in invested-equity share from earlier than 2015 to after 2015, plotted in opposition to its 2013 fairness multiplier. BHCs with bigger reservoirs shift fairness funding extra sharply towards banks (left panel) and away from nonbanks (proper panel). The provision of redeployable nonbank fairness, not organizational complexity alone, determines how a BHC responds to tighter capital necessities.
Fairness Reallocation Heterogeneity: Function of the Fairness Multiplier
Notes: The chart plots every BHC’s pre-post imply distinction within the final result variable in opposition to the BHC’s 2013:Q1 fairness multiplier. The left panel reveals the change in mother or father fairness invested in financial institution subsidiaries as a share of consolidated BHC fairness. The appropriate panel reveals the change in fairness invested in nonbank subsidiaries as a share of consolidated BHC fairness. Each outcomes are expressed in share factors. The pattern consists of BHCs with a minimum of 1 % nonbank asset share in 2013:Q1. For visible readability, the scatter is restricted to BHCs whose pre-post change is inside +/- 20 share factors; the fitted line and the slope reported in every panel are easy OLS estimates on this restricted cross part. The vertical dotted line marks the median fairness multiplier throughout BHCs. *p<0.1, **p<0.05, ***p<0.01.
Capital Strikes. Does Danger Transfer Too?
From the mother or father’s perspective, redistributing funds through its inside capital market is privately optimum. On the consolidated stability sheet, returns on property and fairness rise after Basel III whereas charge-offs fall, with no shift towards riskier property. BHCs should not taking extra threat in combination. As a substitute, they’re reallocating capital throughout subsidiaries in response to variations in how these subsidiaries are regulated. However “no extra threat in combination” doesn’t imply no change in the place threat sits.
Within the remaining put up of this collection, we flip to the nonbank subsidiaries that offer this capital. We present that the identical reallocation that strengthens banks weakens nonbank associates, shifts their exercise towards riskier types of lending, and creates a channel via which misery on the nonbank aspect of the group can spill again onto the financial institution itself.
