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 primary put up documented that nonbank subsidiaries inside financial institution holding corporations (BHCs) are massive, 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 by way of the inner plumbing of the holding firm. The collection attracts on the authors’ latest Employees 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 wanting the brand new requirements had two choices. It may increase contemporary fairness in exterior markets, a expensive 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 complicated BHCs did in response to greater capital necessities.
Extra Capital on the Financial institution, None on the Holding Firm
To establish 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 complicated multi-subsidiary organizations earlier than interstate banking restrictions had been harmonized nationally in 1994. These historic variations strongly predict organizational complexity many years later (as proven within the chart under), but they’re unlikely to be associated to Basel III implementation three many years on. Per 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
Supply: BHC Organizational Construction Database.
Notes: The chart reveals the traits 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 are able to additionally see the issuance margin instantly. BHCs with better deregulation publicity considerably scale back exterior fairness issuance after 2015. Fairly than faucet markets to satisfy tighter necessities, complicated BHCs scale back their reliance on outdoors buyers. That’s solely attainable 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 father or mother and subsidiaries instantly, and so they reveal a clear three-step reallocation amongst BHCs with significant nonbank operations.
Step 1: The father or mother shifts fairness towards banks. After 2015, father or mother fairness investments in financial institution subsidiaries rise by 2.28 share factors of whole BHC fairness per 12 months of deregulation publicity, whereas investments in nonbank subsidiaries fall by an almost similar 2.64 share factors. Complete father or mother investments throughout all subsidiaries are unchanged. The father or mother doesn’t inject extra capital into the group; it adjustments the place current 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 under. Following Basel III, dividends flowing from nonbank subsidiaries to the father or mother improve sharply. Dividends from financial institution subsidiaries, against this, present little change. The father or mother successfully attracts sources from the less-regulated facet of the group whereas leaving the regulated financial institution facet largely untouched.

Notes: The desk presents reduced-form estimates of inner fairness reallocation inside BHCs. The dependent variable in column 1 is fairness investments in financial institution subsidiaries divided by whole BHC fairness. Column 2 is fairness investments in nonbank subsidiaries divided by BHC fairness. Column 3 is whole fairness investments in all subsidiaries divided by BHC fairness. Fairness investments embody widespread inventory, most popular inventory, goodwill, and different intangibles. Column 4 is quarterly dividends obtained by father or mother 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. Publish signifies 2015:Q1 and later. All specs embody BHC fastened results and quarter-year fastened 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. Commonplace errors clustered at BHC stage. Pattern restricted to BHCs with nonbank asset share exceeding 1 p.c.
*p<0.1, **p<0.05, ***p<0.01.
Step 3: Banks retain extra earnings. Fairly than distributing earnings upstream to the father or mother, 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, father or mother fairness injections and elevated earnings retention account for the financial institution capital buildup documented above, even because the circulate of latest capital into the consolidated group declines. The cash by no means enters the group from outdoors; it strikes inside.
The Significance of the Fairness Reservoir
The primary put up on this collection launched the concept nonbank subsidiaries act as “fairness reservoirs” as a result of they maintain a disproportionately massive 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 inner reallocation attainable, 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 under 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 supply of redeployable nonbank fairness, not organizational complexity alone, determines how a BHC responds to tighter capital necessities.

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 father or mother fairness invested in financial institution subsidiaries as a share of consolidated BHC fairness. The proper 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 at the very least 1 p.c 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 Threat Transfer Too?
From the father or mother’s perspective, redistributing funds through its inner 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 danger in mixture. As an alternative, they’re reallocating capital throughout subsidiaries in response to variations in how these subsidiaries are regulated. However “no extra danger in mixture” doesn’t imply no change in the place danger sits.
Within the last put up of this collection, we flip to the nonbank subsidiaries that provide 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 by way of which misery on the nonbank facet of the group can spill again onto the financial institution itself.
