What are the key takeaways from this Odd Lots episode?

Key insights include: **Inflation Threshold Shift:** UK households now notice inflation at 3–3.5%, down from the previous 4% threshold. This lower sensitivity band means any new energy shock triggers faster expectation changes. Policymakers must account for this recalibrated public attentiveness when assessing whether second-round wage and price-setting effects will materialize from each new supply disruption.; **Second-Round Effects Timing Problem:** Central banks cannot wait for concrete evidence of second-round wage-price spirals before acting — monetary policy transmits with an 18–24 month lag. Greene's framework distinguishes three propagation phases: direct energy price effects (look through), indirect effects like food costs (partially lean against), and second-round behavioral shifts (act proactively before confirmation).; **UK Mortgage Transmission Mechanism:** UK households predominantly hold 2- and 5-year fixed mortgages. Even as the BOE cuts rates, consumers rolling off older fixed deals face sharply higher debt servicing costs, suppressing spending. This creates a paradox where rate cuts fail to stimulate consumption, requiring policymakers to separate the rate cycle from actual household financial conditions.

What did Megan Greene discuss on Odd Lots?

Bank of England MPC external member Megan Greene explains why she voted to hold rates despite weak UK growth, detailing how successive supply shocks — from COVID to Ukraine to Iran — have embedded inflation persistence through changed household expectations and firm pricing behavior, complicating standard monetary policy responses.

Key Takeaways

✓Inflation Threshold Shift: UK households now notice inflation at 3–3.5%, down from the previous 4% threshold. This lower sensitivity band means any new energy shock triggers faster expectation changes. Policymakers must account for this recalibrated public attentiveness when assessing whether second-round wage and price-setting effects will materialize from each new supply disruption.
✓Second-Round Effects Timing Problem: Central banks cannot wait for concrete evidence of second-round wage-price spirals before acting — monetary policy transmits with an 18–24 month lag. Greene's framework distinguishes three propagation phases: direct energy price effects (look through), indirect effects like food costs (partially lean against), and second-round behavioral shifts (act proactively before confirmation).
✓UK Mortgage Transmission Mechanism: UK households predominantly hold 2- and 5-year fixed mortgages. Even as the BOE cuts rates, consumers rolling off older fixed deals face sharply higher debt servicing costs, suppressing spending. This creates a paradox where rate cuts fail to stimulate consumption, requiring policymakers to separate the rate cycle from actual household financial conditions.
✓State-Dependent Firm Pricing: Since the pandemic, UK firms shifted from schedule-based price-setting to state-dependent pricing — resetting prices more frequently when inflation rises. This structural change accelerates cost pass-through to consumers. Greene's BOE Decision Makers Panel survey showed firm price expectations one year ahead had stalled above target even before the Iran energy shock materialized.
✓Economic Statecraft as Permanent Supply Shock Source: Tariffs, export controls, and investment restrictions used as foreign policy tools represent recurring negative supply shocks, not one-off events. Combined with climate transition risks, this makes the traditional central banking approach of "looking through" temporary supply disruptions untenable. Greene advocates scenario analysis and risk management frameworks over precise point forecasts.

Notable Moment

Greene revealed that a predecessor MPC member served her entire term without voting to change interest rates once — a scenario now inconceivable. Greene has already navigated a full hiking, holding, and cutting cycle within roughly three years, illustrating how fundamentally the operating environment for central banks has shifted.

Okay. Before we get into it, little side note for the IT leaders listening in. I was reading up on a Microsoft commission survey the other day and learned that teams using Windows 11 Pro PCs report 62% fewer security incidents compared to Windows 10 PCs, including three times fewer firmware attacks. Pretty significant. With security built in, you'll have AI ready IT that sets you up for operational efficiency as well as long term resilience. Upgrade to Windows 11 Pro at windowsmeansbusiness.com. If you follow markets, you know the value of long term thinking. You plan, you diversify, you prepare for volatility. But even the best strategies can't prevent every bad day. For more than seventy five years, Cincinnati Insurance has helped individuals and businesses navigate tough moments with expertise, personal attention, and independent agents who focus on relationships, not transactions. The Cincinnati insurance companies, let them make your bad day better. Find an agent at cinfin.com. The thing about AI for business, it may not automatically fit the way your business works. At IBM, we've seen this firsthand. But by embedding AI across HR, IT, and procurement processes, we've reduced cost by millions, slashed repetitive tasks, and freed thousands of hours for strategic work. Now we're helping companies get smarter by putting AI where it actually pays off, deep in the work that moves the business. Let's create smarter business. IBM. Bloomberg Audio Studios. Podcasts, radio, news. Hello, and welcome to another episode of the Odd Lots podcast. I'm Tracy Alloway. And I'm Jo Wasenthal. Jo, you know one nice thing about getting old? Go on. I've been thinking about this a lot, actually. The nice thing about getting old is that a lot of people that you have known for a very long time and that you've sort of grown up with, let's say, over the years, start to get into really interesting positions and sometimes senior positions or sometimes positions of power. I love this take. Right. Yeah. There are certain people that you don't get to know or you're, you know, when you're in your twenties or whatever, your peers or your peers, and that's great, but they probably aren't, for example, external members of the Bank of England Monetary Policy Committee and so forth or other such roles. But as you get senior, you're like, oh, wow. I know that person. I recognize that name. As you guys like to say who went to university in London, I went to uni with that person. My impression is that everyone in London, quote, went to uni with literally everyone else because I've heard you and Sid say that specific phrase so many times over the last decade. No. Not that often, surely. But you're absolutely right. You've sort of given the guest away. We're gonna be speaking with someone that we've known for a sort of given the guest away. We're gonna be speaking with someone that we've known for a long time, and I …
