A few months in the past now I wrote a publish concerning the new set of low cost charges authorities businesses are supposed to make use of in endeavor cost-benefit evaluation, whether or not for brand spanking new spending initiatives or for regulatory initiatives. The brand new, radically altered, framework had come into impact from 1 October final yr, however with no publicity (besides to the general public sector businesses required to make use of them). The brand new framework, with a lot decrease low cost charges for many core public sector issues, wasn’t precisely hidden nevertheless it wasn’t marketed both.
My earlier publish (most likely greatest learn along with this one) was based mostly largely round a public seminar Treasury did lastly host in February, the advert for which had belatedly alerted me to this substantial change of coverage strategy (and despatched me off to numerous background paperwork on The Treasury web site).
As a fast reminder, low cost charges matter (usually lots), as they convert future prices and advantages again into equal as we speak’s {dollars} (current values). The low cost price used makes a giant distinction: for a profit in 30 years time discounting at 2 per cent each year reduces the worth by virtually half, whereas transformed at 8 per cent the current worth of that profit is diminished by virtually 90 per cent.
Till final October, initiatives and initiatives had been to be evaluated at a 5 per cent actual low cost price – somewhat decrease than the charges traditionally utilized in New Zealand, however not inconsistent with the file low actual rates of interest skilled across the flip of the last decade (recall that the low cost charges didn’t try and mimic a bond price, however took account of the price of each debt and fairness).
The brand new framework, summarised in a single desk, is

and in case there was any ambiguity about the place the main focus now lay, not solely was the non-commercial proposals line listed first however the round itself made it clear that the non-commercial price(s) had been more likely to be the norm for many public service and Crown entity proposals.

Within the earlier publish I outlined a bunch of considerations about this new strategy, each across the substance and what it would imply for future spending (and, for that matter, regulatory) pressures, and round what appeared to have been fairly a rare course of, with no public session in any respect. Treasury officers on the seminar had, nonetheless, assured me that it had all been authorized by the Minister of Finance, which frankly appeared a little bit odd given the (then) new authorities’s rhetorical deal with rigorous analysis of spending proposals and so forth.
Anyway, I went dwelling and lodged an Official Data Act request with The Treasury. They dealt with it pretty expeditiously nevertheless it took me some time to get spherical to working my method by means of the 100+ pages they supplied. This was the discharge they made to me
Treasury OIA re Public Sector Low cost Charges March 2025
and this was their recommendation to the Minister of Finance, already launched however buried very deep in a giant common launch on a spread of subjects. I’ve saved it right here as a separate doc.
Treasury Report: Updates to Public Sector Low cost Charges 30 July 2024
Not one of the launched materials allayed any of my considerations. In truth, these considerations are actually amplified, and added to them is a priority concerning the actually poor high quality, and loaded nature, of the slender recommendation supplied to the Minister of Finance on what will be actually fairly a technical subject however with a lot wider potential political economic system implications. There was an finish to be achieved – officers had been eager on decrease low cost charges – and by no means thoughts a cautious. balanced, and complete perspective. It was maybe summed up within the remark from one principal adviser who famous “I get a bit misplaced on the technical forwards and backwards on SOC vs SRTP” however “I assist shifting to 2%”.
Considerably amazingly, despite the fact that all of the paperwork discuss how a change of this kind actually ought to have ministerial approval – that is even documented within the minutes of The Treasury’s Govt Management Staff assembly of 12 March 2024 – ultimately all they did was ask the Minister to be aware the change they (officers) had been making. All of the Minister was requested to comply with was course of stuff across the begin date and future evaluations. I’m shocked that there appears to have been nobody in her workplace – her non-Treasury advisers, who partially are supposed to guard busy and non-technical ministers from officers with an agenda – who seems to have appreciated the importance of what was happening or thus to have triggered a request for extra and higher evaluation/recommendation. And even, it seems, to have raised questions on what was behind the remark within the Session part of the paper that “To handle dangers of elevating exterior expectations and a threat of extended debate, we’ve not consulted publicly”. Had been there maybe different views then that the Minister ought to have been made conscious of? (The one individuals consulted had been different public sector chief economists – whose businesses will usually be eager on getting undertaking analysis thresholds lowered – and some handpicked consultants.)
What turned extra obvious within the papers was that this complete undertaking had acquired going beneath the earlier authorities (Labour, however with Greens ministers) when the Parliamentary Commissioner for the Atmosphere had prompt in 2021 that public low cost charges ought to be reviewed with a view to adopting a mannequin that may low cost future advantages (relative to upfront prices) much less closely. Treasury had undertaken in 2022 to the (then Labour majority) choose committee that they’d do a overview. Issues appeared to get their very own momentum from there, and nothing about both a change in fiscal circumstances – again in 2021/22 even Treasury was eager on spraying public cash round – nor a change in authorities appears to have prompted a pause. Had the brand new Minister of Finance, or her workplace, been extra alert to the implications, maybe they’d have referred to as a halt to the work programme (however on this event I’m reluctant to place a lot blame on the Minister, as she seems to have been so badly suggested by The Treasury).
The one recommendation the Minister of Finance seems to have been supplied with is the brief paper linked to above. It has simply over two pages of substance (the remaining is course of, plus a 4 web page technical appendix – which I’d think about that, for a noting suggestion solely, a busy – and non-technical – minister wouldn’t usually learn).
It’s placing what the Minister isn’t instructed:
- there isn’t any point out within the paper that the sensible implication of the brand new strategy Treasury was planning to take was that the majority public sector initiatives and proposals could be evaluated main at a 2 per cent actual low cost price somewhat than the (customary) 5 per cent price beforehand. They point out that the SOC-based price is being elevated, in step with the rise in bond charges, however by no means that this low cost price will now not be used a lot.
- there isn’t any try within the paper to the Minister to clarify, or justify, the brand new strategy beneath which low cost charges for years past yr 30 could be evaluated at even decrease low cost charges nonetheless (there are arguments for and in opposition to, however none of it’s talked about and nor are the implications drawn to the Minister’s consideration).
- they be aware the excellence that one price might be used for business initiatives and one for non-commercial issues, however provide no evaluation or recommendation on both why such a distinction ought to be launched or how, both conceptually or virtually, the 2 could be distinguished (they promise they might develop future steering, however this nonetheless seems to not have been accomplished).
- they by no means draw the Minister’s consideration to the truth that one can consider initiatives at any price one chooses however that it doesn’t change the actual fact that there’s a actual value – in debt and fairness finance – which isn’t one million miles away from the Social Alternative Value (SOC) strategy they had been planning to maneuver away from. Tasks that handed a cost-benefit take a look at at a 2% (or 1%) low cost price however failed to take action utilizing an 8 per cent price would, if authorized, merely be being subsidised by taxpayers.
- they by no means drew to the Minister’s consideration that they had been planning to go away the speed of capital cost at 5 per cent, now inconsistent with both strategy to discounting and undertaking analysis
There may be additionally no engagement with a few of the conceptual points raised by what Treasury was planning. That is from my earlier publish

It’s all very effectively for Treasury to say that each proposal should have numbers offered with each a 2% and eight% low cost price, but when they can’t reply easy questions like these (or alert the Minister to them) then all they’ve accomplished is launched a pro-more-spending muddled mannequin.
Maybe most breathtaking was the daring declare (provided with no supporting evaluation in any respect) that “The up to date low cost charges is not going to change the greenback quantity of spending, since particular person spending proposals will proceed to be prioritised inside a funds constraint (fiscal allowances).”
It’s the type of declare that if a primary yr analyst had made you may take them apart and clarify one thing about incentives, political economic system, and what was and wasn’t mounted within the system. This paper was written and signed out by a extremely skilled Principal Adviser and a extremely skilled Supervisor, and the coverage had been signed off by the complete Govt Management group.
By no means as soon as it’s identified to the Minister that funds allowances (whether or not capital or working) are hardly immoveable stakes within the floor, enduring come hell or excessive water from decade to decade. (Why, this very morning, the working allowance for this yr was altered once more). Or that the general impact of what Treasury was planning on doing would imply that extra initiatives (spending proposals) and extra regulatory initiatives would cross a cost-benefit take a look at and present a optimistic internet current worth. And that whereas, in any specific yr, an working allowance may bind (in order that solely – no less than in precept – probably the most extremely ranked initiatives (in NPV phrases) would get authorized, over time if extra initiatives and regulatory proposals confirmed up with optimistic NPVs the stress could be more likely to mount – whether or not from public sector businesses or outdoors foyer teams – for extra spending and extra regulation. (In truth, Treasury by no means even identified the working allowance is a internet new initiatives determine and better taxes can permit increased spending even inside that self-imposed momentary constraint.) And that even when a Nationwide Occasion minister may satisfaction herself on her authorities’s supposed capacity to restrain spending, time will cross, governments will change, and future governments which can be predisposed to spend extra will maintain workplace. Sharply reducing low cost charges – to miles beneath the precise value of capital – was simply an invite to such governments. It looks like fiscal political economic system 101…..and but not solely is that this subject not touched on within the recommendation to the Minister there isn’t any signal of it in any of the opposite paperwork Treasury launched to me. You wouldn’t get the sense in any respect both that the fiscal start line was one during which New Zealand now had one of many largest structural deficits within the superior world, with even a projected return to surplus years away.
Treasury appears to have simply needed decrease low cost charges.
You get this sense on this extract from that brief paper to the Minister

Goodness, we wouldn’t need anybody debating the suitable low cost price would we, so let’s simply render it moot by shifting to an especially low price (in a rustic with a traditionally excessive – by worldwide requirements – value of capital). Or, we don’t anybody fudging their cost-benefit evaluation – however isn’t Treasury presupposed to be a few of gatekeeper and guardian of requirements – so we’ll simply make it straightforward and slash the low cost price massively. And as for that declare {that a} 5 per cent low cost price – miles beneath any credible estimate of value of capital or non-public sector required hurdle price of return – incentivises decisionmakers to deal with the short-term, there isn’t any critical (or unserious) evaluation offered to the Minister suggesting this was in actual fact so (that numerous initiatives with compelling circumstances had been lacking out), nor any try and recommend that capital is in actual fact expensive, and that when it’s expensive there ought to be a excessive hurdle typically earlier than spending cash that has payoffs solely far into the long run.
There may be, it is best to be aware, no corresponding paragraph outlining the inducement results and dangers round what Treasury was planning on doing.
There was a time when you can depend on The Treasury for actually good and critical coverage recommendation. If this paper is something to go by, that day is gone. Modifications of this magnitude ought to have been accomplished solely with the Minister’s specific approval and may most likely solely have been accomplished after critical and open public session. And the Minister was entitled to anticipate a lot better, and fewer loaded, recommendation than she acquired on this subject, the place what Treasury was planning ran immediately counter to the general route of the federal government fiscal coverage and spending rhetoric. The Minister herself most likely ought to have had higher and extra demanding advisers in her workplace, however actually the prime duty right here for a foul, muddled and ill-justified change of coverage rests with The Treasury.
(And in case you suppose I’m a lone voice in having considerations, right here is column from a former very skilled Treasury official who had appreciable expertise in these and associated points)
