The transformation hasbeen profound, but the industry must now respond to two new andsignificant shifts in the operating environment:•The end of the easy monetary policy and fiscal stimulussupercycle, already under way•The introduction of a new capital regime worldwide, albeitwith highly uncertain parameters and timelines for imple-mentation across different jurisdictionsWe expect these changes to influence the revenue and returns out-look for the industry. In March of this year, rapidly rising interest ratestriggered a contained banking crisis that challenged some long-standing assumptions about liquidity and interest rate risk manage-ment in banking. Structurally higher interest rates put the brakes ondemand for the Advisory and Underwriting business that fueledindustry revenues and returns through the pandemic. And new cap-ital rules, particularly the Basel 3 Endgame rules proposed by US reg-ulators, have the potential to structurally change the economics ofwholesale banking and drive activity out of the banking system in anextreme scenario.We have created a framework to assess the impact of proposedchanges to capital rules on the economics (and potentially the perim-eter) of wholesale banking.The range of potential outcomes is wide, given significant uncertaintyover the final rules that will be implemented and the mitigatingactions that banks can take. We estimate that risk-weighted assets(RWA) required to support the existing US wholesale bankingindustry would rise 35% under the proposed new US capital rules,which are more conservative than global standards but subject tochange. Competition from international banks and non-banks isfierce and, in the unlikely event that the proposed rules pass in theircurrent form, we could see up to ~$40BN (~13%) in revenue exit USbanks through value shifts and capacity reductions.Not all the news for banks is bad. Structurally higher interest rateswill drive stronger revenues and returns for banks with sizeableTransaction Banking and Securities Services businesses. In our basecase, we project that these businesses will have grown 39% and 14%respectively between 2020-2025 to represent 29% of the
