Investment banking has a habit of promoting its best executors.

The Analyst who never misses.
The Associate who controls every detail.
The VP who can run the hardest deal in the room.

And for good reason. Excellence matters. But there is a quiet truth many firms learn the hard way:

The behaviours that make someone a top performer do not automatically make them a great manager.

In a recent conversation with Larry Wieseneck, Head of Corporate and Investment Banking at TD Securities, he made a distinction that every aspiring leader should understand.

Leadership and management are not the same thing.

They overlap.
They reinforce each other.
But they are not identical.

Leadership is about creating followership. Management is about learning the functional discipline of running people, resources, risk, and performance. And at senior levels, you eventually need both.

Before discussing leadership, Larry was clear on one point:

You cannot skip the fundamentals. In investment banking, credibility is earned through excellence in your seat.

As Larry put it: “Excellence in your seat is non-negotiable.”

If you want to lead high-performing producers, you first need to have been exceptional at the job yourself.

Junior bankers sometimes want to rush toward leadership, client ownership, or strategic influence before they have fully mastered the building blocks. That is dangerous. The best way to create future leadership optionality is still to become an outstanding Analyst, Associate, and VP.

Not average.
Not competent enough.
Unusually strong.

Because in the front office, respect is hard to fake. High performers rarely follow someone who has not first earned credibility through their work.

The real challenge starts once someone has proven they can execute. Investment banking often asks people to make a sharp transition:

From running deals to running people.

From controlling outputs to influencing outcomes.

From being the player to becoming the coach.

That sounds simple. It isn’t. For a top producer, success is often defined by control. You own the model. You manage the client. You drive the process. You know every page, every issue, every pressure point. But management changes the equation. Now success depends on whether other people do their jobs well. That can feel uncomfortable, even threatening, for high achievers who built their reputation by personally ensuring nothing went wrong.

The best executors often struggle because they keep trying to control the work rather than building the system that enables others to perform. That is not leadership. That is extended execution.

Larry identified several reasons this transition is so difficult.

The first is that banking does not always provide enough intermediate steps. In some businesses, management responsibility develops gradually. In investment banking, the leap can feel sudden: one day you are a full-time producer; the next, you are expected to run a group, manage performance, navigate resources, and think about economics.

The second challenge is loss of control. Top performers are used to being the answer. Managers have to build an environment where others can find the answer. That requires patience and trust.
delegation and the ability to tolerate imperfection while people develop.

The third challenge is that management requires a different toolkit. Winning a mandate is not the same as managing a P&L. Running a process is not the same as managing expenses, capacity, resource allocation, morale, and long-term franchise health. These skills can be learned, but they do not come automatically just because someone was excellent at deals.

One of Larry’s most important points was that leadership is not just about title. It is about whether people choose to follow you. That can come from integrity, credibility, judgment, generosity, or the ability to create belief.

Some people are natural mentors and leaders without wanting the full headache of formal management. They may inspire others, develop talent, and build trust, while having little appetite for expense ratios, P&L oversight, or administrative complexity.

That distinction matters. Not everyone who leads wants to manage. But at the most senior levels, especially if you want to run a business, inspiration is not enough. You need the followership of a leader and the operating discipline of a manager.

So how do aspiring leaders develop these skills before they are formally run a business?

Larry pointed to one overlooked training ground: Staffing.

Being a staffer forces you into the real tension of management.

Senior bankers want coverage. Juniors need development. Deals require resources, and there are never enough people. You are constantly balancing urgency, fairness, capability, and risk. That is management in miniature and a great training ground.

Larry described staffing as a vital prerequisite because it teaches future leaders how to allocate scarce resources under pressure, one of the core realities of running any business.

If you want to become a better manager, pay attention to staffing. Not as administration but as leadership practice.

Another strategy Larry uses is the task force model. When complex firm issues arise, he creates groups that allow emerging leaders to step forward. These task forces become a kind of leadership laboratory.

They reveal who has:

This matters because leadership is not only tested on live deals. It is tested when there is no clear answer, no obvious owner, and no immediate fee attached. The people who self-identify in those moments often show the instincts required for broader leadership.

They are not just asking: “What am I responsible for?”

They are asking: “Where can I help move the firm forward?”

That is a different mindset.

One of the biggest signs of leadership maturity is expanding your field of vision. Early in your career, you focus on what you control. Your model, your pages, your workstream and your client call. But as you move toward MD and beyond, your effectiveness depends increasingly on your areas of influence.

This is where many execution-driven bankers struggle. They are excellent inside their lane, but frustrated when progress depends on others. Leadership requires learning how to get things done without direct control. That is not politics; it is influence.

There is one final warning in Larry’s message that feels especially relevant today.

Tools are changing fast. AI can accelerate research, modelling, drafting, and workflow. But Larry cautions against using tools as a substitute for understanding. You cannot become a true advisor if you have not done the hard yards. You cannot lead experts if you have never built expertise yourself. And you cannot become interdependent, a good partner, manager, or leader, before you have first become independent.

That sequence matters. First, master the building blocks. Then, learn to lead beyond yourself.

The industry needs great executors. But execution alone is not leadership.

Leadership begins when your success is no longer measured only by what you personally deliver, but by the performance, growth, and trust of the people around you. That shift is uncomfortable for many high achievers.

It requires giving up control without giving up standards.

It requires learning management as a discipline, not assuming it comes with seniority.

And it requires understanding that credibility may get people to listen, but leadership is what makes them follow.

So if you are an Analyst, Associate, VP, or Director thinking about the next stage of your career, ask yourself: Am I only becoming excellent at the work? Or am I also learning how to build the conditions for others to be excellent?

Because the first makes you valuable. The second makes you a leader.
