An annual number hides a sequence
A bank's annual income plan can look coherent while the months inside it do not join. A closing balance may be treated as though it existed throughout the year. A rate assumption may take effect before the relevant contracts can reprice. Deposit renewal behaviour may be represented by a convenient average that obscures a difficult quarter. My view is that the first challenge to such a plan should concern its calendar. Asking for greater commercial effort before understanding the sequence risks turning an arithmetic problem into a test of personal commitment.
At Lurenshan Commercial Bank, our initial net-interest income plan combined average balances with year-end assumptions. The approach made consolidation straightforward, but it did not adequately represent the timing of loan repricing and deposit renewals. Treasury could see the mismatch in its own schedules. Commercial teams were discussing an annual figure that did not expose the same pattern. Neither group lacked effort. They were using different views of the balance sheet, and the planning process had allowed those views to meet only after an apparently settled number had acquired an audience.
I asked finance to rebuild the relevant part of the forecast using monthly cohorts. Where we had contractual dates, the model used them. Where customer behaviour remained uncertain, we identified an assumption rather than presenting an estimated date as a known event. The revised case removed CNY74 million of unsupported net-interest income from the initial plan. This was a correction to a forecast. It was not a realised loss, a cash saving or evidence that the commercial organisation had suddenly become less capable of serving its customers.
The immediate response was uncomfortable. The chief executive questioned whether finance was becoming overly cautious, while business leaders wanted to retain the earlier ambition. I understood that concern. A planning process can become so focused on qualification that it offers little help in deciding what to do. But the answer was not to restore an unsupported assumption. We needed to separate the expected sequence of the existing balance sheet from actions that might change that sequence or add a different source of income during the planning period.
Give every assumption a date and an owner
The monthly view made several kinds of uncertainty easier to distinguish. Some dates were contractual. Some depended on a customer's decision at renewal. Some represented management's intention to change pricing or business mix. These categories required different evidence and different owners. A commercial intention could be credible without being completed, and a historical pattern could be useful without being certain to repeat. Recording those distinctions helped the team explain a forecast revision without implying that the earlier preparer had necessarily made an error or concealed a fact.
I wanted ownership to mean the ability to explain and update an assumption, rather than responsibility for making reality obey it. A colleague supplying a renewal estimate should be able to state its basis, identify new evidence and revise the view when appropriate. If ownership is interpreted only as accountability for hitting the original number, the process can discourage learning. The forecast then becomes less informative precisely when conditions change. Finance needs enough discipline to track revisions and enough openness to let a well-supported revision improve the account.
The calendar also changed how we discussed alternatives. Instead of adding a broad annual adjustment, we could ask when a proposed action might affect balances or rates and what had to happen first. A pricing initiative with a long approval and communication process would not contribute a full year's effect immediately. A change in customer mix could have a different timing profile from a change in contractual repricing. Making those sequences explicit did not resolve every uncertainty, but it prevented unlike proposals from being treated as interchangeable ways of filling one annual gap.
There was a cost to this detail. The first version took more effort to prepare and more time to review. Some colleagues worried that the model would become too elaborate to maintain. I accepted that risk and limited the most detailed treatment to assumptions material to the decision. A forecast should not become an archive of every available data point. It should contain enough temporal structure to explain the result and enough simplicity for the responsible team to keep it current. Unmaintained precision would have been a poor substitute for our earlier convenient average.
Keep ambition answerable to an action
We accepted the lower base case and retained alternatives for different repricing and renewal patterns. Commercial ambition remained part of the discussion, but it needed an action, an owner and a plausible implementation period. This made the executive review more demanding. It was no longer sufficient to say that a business would recover the difference through better execution. The team had to explain what would change and when the financial effect could begin. That discipline allowed finance to support an ambitious proposal without disguising it as an established feature of the current book.
The eventual annual net-interest income variance against the revised plan was CNY29 million. The preceding year's variance had been CNY118 million. I report both figures with caution because the business mix and market conditions differed. The comparison is consistent with a more useful planning process, but it does not prove that the new method caused the whole improvement. I would also examine the revisions made during the year, the decisions those revisions supported and the parts of the forecast that remained difficult to explain. A single favourable variance cannot answer all of those questions.
For a board reader, the dated view creates a different kind of challenge. Directors can ask whether the planned result depends on a concentration of renewals, an assumed rate movement or an action whose implementation is still uncertain. They can also ask what management would change if the sequence differs from the plan. Those are more concrete questions than whether the executive team is sufficiently committed to a demanding annual number. Commitment matters, but it cannot bring forward a contractual date or make an unapproved initiative operate for twelve completed months.
I would introduce this work earlier next time. Rebuilding the sequence late in the planning cycle meant that colleagues had already discussed and defended the initial figure. The correction therefore carried an emotional cost as well as an analytical one. An earlier shared view would have given commercial teams more time to develop alternatives and the executive committee more time to compare them. It would also have reduced the temptation to treat a finance revision as an objection to growth rather than an explanation of when income could plausibly emerge.
The calendar is not a substitute for judgement. It is a way to make judgement visible in the periods where its consequences occur. I still expect a CFO to challenge cautious assumptions, support credible commercial initiatives and help colleagues find a better answer. I also expect the forecast to distinguish an aspiration from the sequence that would deliver it. When those are kept separate, the organisation can discuss ambition honestly. It can ask for a stronger plan without first asking its accounts to describe a year that the underlying balance sheet cannot yet support.
