href=\"https:\/\/www.efinancialcareers.com\/news\/what-is-an-investment-bank\">Investment banks<\/a> often have a funny kind of \u201cfrenemies\u201d relationship with that part of their client base which consists of other financial institutions.\u00a0 It is possible to make a lot of money out of dealing with them, but there is often quite a lot of overlap between the clients\u2019 business, and things which the bank would like to make money out of itself.\u00a0 This tension has to be managed quite carefully; in prime brokerage, <a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.efinancialcareers.com\/news\/financial-sponsors-bankers-2026\">financial sponsors <\/a>and several other areas, the banks want to help their clients do well, but maybe not to do too well.<\/p>\n<p><a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/whatsapp.com\/channel\/0029VacsPmzKGGGK91C7dR39\">\ud83d\udca5Follow us on WhatsApp for news alerts.<\/a>\ud83d\udca5<\/p>\n<p>An important recent example of this might be the growth of market making firms like<a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.efinancialcareers.com\/news\/2022\/10\/how-to-get-a-job-at-citadel\"> Citadel Securities <\/a>and of <a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.ft.com\/content\/07e849ac-ea87-4227-81d4-7f18b0d7d473?syn-25a6b1a6=1\">proprietary trading firms like Jane Street<\/a>.\u00a0 In a short period of time, they went from useful counterparties, to being serious competitors, to taking dominant share in a corner of the market (cash equities trading) which the banks had previously considered their own.\u00a0So when Jane Street started to move into fixed income, this understandably raised concerns.<\/p>\n<p>The <a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.ft.com\/content\/07e849ac-ea87-4227-81d4-7f18b0d7d473?syn-25a6b1a6=1\">Financial Times<\/a> is reporting that JPMorgan (and possibly other banks \u2013 nobody is willing to talk on the record) has significantly reduced the amount of lending that it is prepared to extend to Jane Street, and to other market making firms like Citadel Securities.\u00a0 There might be all sorts of reasons for that, but it is noticeable that the move came shortly after Jane Street began to offer quotes in US Treasuries, and after<a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.efinancialcareers.com\/news\/jpmorgan-citadel-securities\"> Citadel Securities poached JPMorgan&#8217;s head of high touch trading <\/a>and then Jamie Dimon mentioned the firm as a significant competitor in his shareholder letter.<\/p>\n<p>\u201cPeople familiar with the situation\u201d suggest that there had been \u201cinternal tensions\u201d at JPM, with the trading desks getting unhappy that other parts of the bank were financing an attempt to eat their lunch.\u00a0 Since JPM apparently provided about 5% of Jane Street\u2019s total leverage, it\u2019s hard to say that this was the only thing going on, but they might have had a point.<\/p>\n<p>Under Jamie Dimon, JP Morgan has made something of a habit of being the first of the bulge bracket to stand up and defend the franchise against client-competitors.\u00a0 He led the way, for example, in putting an end to the practice of \u201c<a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.ft.com\/content\/cca6a7f9-2319-4a57-b6e5-800e6f5aff6d?syn-25a6b1a6=1\">on cycle recruiting<\/a>\u201d, whereby private equity firms effectively used the sell side as a free training program for their analysts.\u00a0 At the time, this was seen as a courageous move, which might have damaged JPM\u2019s relationship with the important and lucrative financial sponsors client base.<\/p>\n<p>If the rest of the Street follows JPM\u2019s lead, then although the proprietary trading firms are unlikely to go away entirely, they might at least be slowed down in their growth.\u00a0Sometimes the most important role of a market leader is to provide leadership.<\/p>\n<p>Elsewhere, when Jamie Dimon finally retires and the definitive biography of his career is written, one of the most important chapters will detail how he built his reputation as a loyal lieutenant (of Sandy Weill), and then cemented it after leaving to turn around a troubled bank (Bank One).\u00a0 It\u2019s quite a story.\u00a0 And even more interestingly, it\u2019s one which appears to be repeating itself, as Mike Lyons <a target=\"_blank\" rel=\"noopener noreferrer nofollow\" href=\"https:\/\/www.bloomberg.com\/news\/articles\/2026-08-31\/moynihan-protege-gets-shot-at-fixing-dead-money-bank-truist\">takes over the CEO role at Truist<\/a>.<\/p>\n<p>Lyons started his career at Fleet Bank, on the strategy team of its then CEO, Brian Moynihan.\u00a0 After leaving that job to join Morgan Stanley, and then spending some time as a hedge fund manager at Maverick Capital, he returned to work with Moynihan as head of corporate strategy at Bank of America.\u00a0He left BoA in 2011 to help build PNC Bank into a midwestern powerhouse.<\/p>\n<p>And now he is being given his first major banking CEO role, at Truist, the biggest bank in the Southeast USA, but a perennial underperformer that needs a bit of firm management after two previous \u201cdecisively nice\u201d leaders.\u00a0 If the story continues in the same way, we should probably expect to see him coming back to Wall Street in triumph some time around 2030.<\/p>\n<p>Meanwhile \u2026<\/p>\n<p>There is a lot of coming and going in the FX derivatives market; HSBC have hired Pierre Viandaz, formerly an MD at Goldman Sachs.\u00a0 Goldman also recently lost Andrei Kazantsev to Citigroup, but have hired
