Thank you, Sarah. Informative as always. I think this time last year we were talking about inflation, which obviously has been topical over the last 12 months, referenced many times in your presentation. I guess as you reflect back to us sitting on stage this time last year to where we are today, any sort of thoughts you want to share with us? I guess, from my point of view, I heard you say that were pretty close or within the band of inflation, but I think households are still experiencing high prices. Inflation tends to look a little over that inflation band that you discussed. So, how are you thinking about that and, when do you think that what can households and us all expect going forward?
Sarah Hunter
Yes, its a good question. I think when I was here a year ago, I was talking about inflation expectations and how important it was to us to keep them anchored, and how pleased we were that that seemed to be the case. Im very pleased to be able to say that still looks like its the case. We dont see any signs that theyre becoming de-anchored. And - in terms of actual inflation - our forecast a year ago, we were expecting and obviously hoping that wed continue to see underlying inflation - so we measure that through trimmed mean - to continue to moderate through this year and to be approaching - to be inside the target band by this point and certainly approaching the midpoint by the end of the year. Its very pleasing to see that that has generally played out. We obviously had trimmed mean inflation at 2.7 per cent for the June quarter. But we are monitoring, and we are always looking and seeing how things are developing, and in the latest monthly indicator prints what we have seen is that a couple of the components that we monitor very closely, where you can get a good read from that monthly indicator, have come through a touch stronger. The Governor mentioned housing inflation and market services and so those are particular watch points for us. What we want to try and do from here obviously is keep inflation more or less where it is now and, in the underlying sense, around about that 2.5 per cent, the midpoint of the target band. So thats why were going to be monitoring risks to both sides, but in the latest data in particular weve seen it come through a touch higher.

Fantastic. Im going to ask one more question. I think theres going to be a tonne of questions out there in the room. Im particularly interested in just asking a question about AI and productivity. Obviously, weve heard here over the last 24 hours a lot of AI discussions in every topic pretty much. You referenced AI - or emerging technologies - in your address. How are you incorporating the impact of these potential emerging technologies into your forecasting? What timeframes do you think were likely to see AI or any technological gains coming through?
Sarah Hunter
Yes, excellent questions. Its very much an emerging nascent question, so Im not going to pretend I have the answer to these things or that we have a crystal ball back at the office that we can rub and know for sure. Were thinking about it in terms of looking at historical experience with a generalist technology like this. And a couple of observations from history are one, it does take some time, so its unlikely to erupt and emerge in the next three to six months, we think itll take a little bit longer than that. And two, the technological gains can potentially come in almost waves. We first use the technology and that gives us some uplift. Then we work out how to use it better and that gives another uplift down the track, so it could well take a number of years for these things to flow through.
My final observation is that if you look through history, each sort of big generalist technology thats emerged and then been adopted, the speed of adoption has generally increased over time. So, it took a lot less time for the internet to become well established than it did for electrification, for example. I dont know but it certainly feels like this time is moving pretty quickly again, so perhaps were not talking decades and decades, but I think we probably are talking years. And thats why were very conscious that this change to our productivity assumption. Were very much thinking about it as our view for the next couple of years. We will revisit this because I think even in two years time well know a lot more about the impact AI is having here and around the world, and then well have to look to potentially change that assumption in one direction or another. Its certainly not a set and forget.

Yes. So remaining patient, I guess, and observing what is happening out there and proactive around integrating those into your forecasts.
Sarah Hunter
And actually, rolling out this technology for ourselves within the Bank. So, how do we make use of it and how does it improve what we do, the quality of the analysis, and the breadth of that that we can give to the Board?
Moderator
As a bank were also going through the same process. I might throw to the floor. Ive got a tonne more questions as I said, but weve got the opportunity now to ask your questions of Sarah. So, well start down here.
SPEAKER
I was wondering if you could talk about how you think about the risks of a head fake in the inflation data. Clearly the high frequency data suggests that inflation maybe is a bit hotter in Q3. Weve had that signal before, from the data, and it turned out to not be the case. And then Im also reminded of the US, which I think has quite high-quality inflation data and has obviously had - that started this year, a bit of a high inflation scare but its ended up being quite moderate. How do you think about those signal to noise judgments in the context of what I think to be - I mean, no disrespect to the ABS - but I think that the US data is probably higher quality than the Australian data, at least at this moment in time. And I guess, just to tie up the question, it does seem like an unusual place to end an easing cycle with the unemployment rate trending up and policy a little bit restrictive. So maybe you can fold that into your judgments about the inflation pulse.
Sarah Hunter
Great question. So, could we be head faked by the inflation numbers? Look, thats always something thats on our mind. I mean, the fundamental of any type of analysis of any given data point is how much is signal and how much is noise. And so, we dig into all of the series to really try and understand that, and obviously you do have to make some judgments about that too. If you knew precisely, there wouldnt be this risk, we wouldnt have to worry about it.
In terms of the latest data and our read of it and our sense of it, so we - particularly with the monthly CPI indicator - really dont look at the aggregate indices that are published, so thats the headline series and also the monthly trimmed mean. Thats because the coverage is incomplete and various other challenges there. We really do focus on the components where they give a genuine read. So, thats why month one you get less information because its less complete. Month two is a good month because you get market services and thats for the quarter, not just for that month. And so, I suppose our read of the data is looking at those components where we have, at least more confidence than in others, that the two months together are giving us some signal. But could we see a bit of a drop back down in the December quarter for instance, that theres some one-off temporary factors in there? Absolutely. Were not discounting that fact and obviously were working through that at the moment in the context of our November forecast. So, youll see where we land up in all of that in a few weeks time.
In terms of thinking about that and in the context of restrictiveness of policy and those sorts of questions, I think the key question for us really, in terms of policy setting, is what are the outcomes that we think were going to achieve over the one to two-year horizon. So, youve heard this from many central bankers Im sure, monetary policy acts with a lag. So, were not influencing the data that we get today. Well, clearly not because that was from backward-looking anyway. But beyond that were not really having much of an impact on the economy in the very near term, the three to six months. Its only in the six, 12 to 18-month horizon that whatever decision is made today has an impact. So, were always forward looking and our assessment and our advice to the Board, in terms of the policy settings, is looking ahead to that point in time. So, whether we think we have to stay a little bit restrictive or change that is really a function of what we think the economy is going to look like in 12 months. And thats really the key judgment for us in terms of that policy advice.
My final comment on that is that I often get asked about neutral, whats the neutral rate for the cash rate, and how quickly youre going to get there, those sorts of things. Any estimate for neutral, number one, has incredibly wide error bounds. Its an incredibly hard thing to estimate. And number two, its a long run concept that takes - that looks through, if you like, all the shocks and shifts and everything else that might be playing out at any given point in time. Of course, at any given point in time, there are always shocks and shifts running through the economy and today is no different. So neutral is only ever a guide. Its, sort of, up there at the top. It is not the anchor point for actual policy setting.

Do we have another question from the floor? Microphone down the front. Thank you.
Speaker
Arguably interest rates before COVID were far too low and, of course, they got to very low levels in Australia and elsewhere. What do you think central banks, including the Reserve Bank, learned from that period? And what do you think is - I mean, we used to read the textbooks that you had a zero bound on interest rates, but you know that was proven not to be true. But what do you think is a - sort of, a lower bound on interest rates in the future?
Sarah Hunter
Its a good question. It comes a little bit back to the question around neutral and what is neutral. But I think more generally, yes, the rates were low and then went to the zero lower bound during COVID, that was clearly an exceptional time where all arms of policy were providing exceptional support to the economy. I would never discount the risk that we end up with another such event that requires that type of support. So, I would never say that we wont go back to the zero lower bound. I think you always have to prepare for those very, very bad outcomes and they can materialise in the future. And colleagues in the financial markets group at the Bank are always looking at what monetary policy implementation looks like if we did have that very bad outcome. So, I guess thats one part to your question.
In terms of where interest rates are now and what is neutral now compared to pre-COVID, that is very, very hard to know. Different models will give you very, very different answers to that question. That was my point around the error bands around these models are really wide. So, I dont have a definitive answer for you. The best answer that we will ever get is what we observe happening in reality to interest rates, but then also to economic outcomes. Thats ultimately going to tell us where neutral is. But where it is today precisely, I dont know. I cant tell you that and most central bankers will say the same. We dont know. If it was that easy, the job would be a lot easier. Unfortunately, its not.

Thank you. Bringing it back to productivity, you mentioned that weve seen productivity growth slowing since the mid 2000s. There are a number of factors, I guess, that you called out there - technology lag here versus in the rest of the world, competition decline etc. What can Australian businesses do, beyond what government can do, to improve productivity in the private sector?
Sarah Hunter
Oh, what a question. If there was an easy answer to that question, wed all be doing it already and we wouldnt be talking about it and trying to work it out today. I think whats interesting for an economy like Australia, and I mentioned some of the research that my colleagues at the Bank have done on this, is that we are a small open economy, relatively small in the grand scheme of things, and so diffusion of new technologies that may be coming in from overseas is particularly important. Its very hard for us to break new ground right across all sectors of the economy, because of our size and scale, were just not that big. So, diffusion is really important and so thinking about how we bring in and propagate through the economy new technologies I think is going to be pretty critical. But beyond that and to the specifics for specific businesses, I think thats pretty tricky to completely work through. And to be honest with you, its not an area that we at the Bank focus on. Its not our core mandate. The Productivity Commission and others have got lots and lots to say on that so I would always send people in their direction.

Thank you. Another question over here, in the middle.
Speaker
Thank you for your time. I had a question around Q2 consumption data was obviously quite strong, but people were calling out a lot of one-off factors within that data. Are you able to talk about how youve seen Q3 consumption data tracking so far and whether thats as you expect - and how youre thinking about that going forward?
Sarah Hunter
Great question. The consumption data at the moment definitely looks like its being impacted by seasonal shifts. So, were getting these very strong December quarters that we think are related to Black Friday, and then you get a softer March quarter and then theres potentially a less severe, if you like, version of that for the June quarter within the end of financial year sales and that sort of thing. Timing of school holidays can have an impact too. So, we are aware of that and also, of course, running through the consumer spending numbers at the moment and the timing of the end of electricity rebates and, sorry, this is a technical point, but when that happens in a national accounts measurement perspective, the payment for the consumption of electricity transfers back from government to households so thats another additional challenge to work through at the moment.
In terms of the latest data for the September quarter, with all of that, we were actually expecting maybe the momentum might soften a bit, just from some of these technical adjustments really. So, not in a fundamental sense, but in an adjustment sense. The data hasnt been too surprising for us. Weve certainly not been surprised on the downside with it. Its a bit choppy, as it always is. And that monthly spending indicator that we get from the ABS is still new and so were still learning about it. I think everybody is. But we certainly havent been this surprised on the downside by what weve seen, but obviously well find out in a couple of months time how it plays out.

Paul.
Speaker
Thanks, Sarah, for your comments. I just wanted to explore a little bit further the point about lags in monetary policy. One thing that we know already is that house prices have responded quite promptly to the easing so far and that presumably means that, sort of, down the track, and to this earlier - to the previous question, consumer spending is going to pick up so - through several channels. So just interested in your thoughts around how youre thinking about this, sort of, transmission mechanism, particularly through the housing market.
Sarah Hunter
Yes. So, the housing market, the established markets for house prices effectively, its the first and one of the most responsive parts of the domestic economy in terms of monetary policy transmission. Were obviously tracking whats happening in that market with house prices. Its sort of in line with what weve seen in previous easing cycles – so were not surprised theres been a pickup. Weve seen that before and we understand why from a cyclical sense because lower interest rates increase peoples borrowing capacity and then that naturally flows through. So, were not surprised that thats happening. Were certainly tracking it. Its not out of line with what weve seen in previous cycles but obviously theres always a lot of other things running through that market at any given point in time and thats certainly something were going to be focused on moving forward.
I think where you do get the sort of lag starting to materialise, in terms of economic activity and actual inflation outcomes, because obviously house prices are not in the inflation basket is in via, as you mentioned, consumption but also dwelling construction and that does take a bit of time, you know, if youre going to build your own home. Even a detached home youve got to get the approvals; youve got to get the work underway and that takes a number of months. If were talking about high density housing construction, that can take years to, sort of, get it off the ground and fully make it through to completion. So thats the kind of lag that Im talking about, when Im talking on a 12, 18, even 24-month horizon. But, no, were certainly monitoring it, and were not surprised that weve seen a pickup, and its certainly something that well be paying attention to - how much of a pickup and how much continues from here, in terms of the outlook.

Thanks, Paul. Weve probably got time for one more question. Over here.
Speaker
Thanks, Dr. Hunter, for your speech. Stephanie from the ABC. Sorry to bring up the topic, but you mentioned uncertainty and obviously a major source of uncertainty is the US trade war and weve seen some reignition of tensions between China and the US in the recent week. How much is that factoring into the difficulty around forecasting? You know, you said your August forecasts were pretty good, but given this is now dragging on for a significant amount of time what challenges is that creating, and I guess what have you seen so far, in terms of the balance of risks around inflation and growth risks?
Sarah Hunter
Yes, its certainly an unpredictable situation to be dealing with. Were still in a phase seemingly where we wake up at the start of the day and theres another fairly major announcement come through. So, my China team and my international team more broadly are getting a real workout at the moment. Theyre working very hard on this, and it is pretty challenging. And the latest escalation is obviously still pretty new as well. So we are, as everyone is, still working it through. So, I dont have definitive answers for you. Well obviously take a view when we come to November in our next forecast.
But generally speaking, what weve seen historically time and again is that uncertainty does drag on the outlook. It makes it very hard for businesses to make decisions, in particular around investment. It can be challenging for consumers as well, if youre concerned that you might be at risk of losing your job or what have you then that can dampen your spending too. What weve seen in the data through to now, I think, is that theres some of that may be coming through in the US, around their labour market data in particular. Were seeing less evidence of that here in Australia. And, you know, we can ask in our liaison program, for instance, what decisions might be delayed because of uncertainty. Were not really hearing too much of that at the moment. Were not seeing too much of an impact in the business surveys, for instance. So - but we are very watchful of it and mindful of it. Weve been calling it out in the last two SMP sets of forecasts, and well certainly have more to say in November. Yes, its a very unpredictable situation and that does make it challenging.

Thank you, Sarah. Were out of time unfortunately, but she spared the question I was going to ask on CBDC and stablecoins, so well save that for another day. But please join me in thanking Sarah for her time here this morning.
