Latest / The Federal Reserve Podcast with Fexingo: Interest Rates, FOMC Meetings, and Monetary Policy / The Fed's Quiet New Tool for Inflation Control
Transcript
- Lucas: So, Luna, when we talk about the Fed's toolkit, we always think of the big hammer: the fed funds rate. But there's a quieter, more precise instrument that's been getting a lot of attention lately, especially with Kevin Warsh at the helm. I'm talking about the interest on reserve balances, or IORB. Luna: Right, the rate the Fed pays banks on the reserves they park at the central bank. That's the one that's actually at 3.65 percent right now, just above the fed funds daily rate of 3.63. But why is that becoming such a big deal? Lucas: Because it's the Fed's precision tool for steering short-term rates. Instead of moving the whole target range for the fed funds rate, the Fed can nudge IORB by a few basis points to fine-tune conditions in the money market. It's like adjusting the thermostat in a room rather than turning off the entire heating system. Luna: So it's a more surgical approach. But what's the actual transmission mechanism? How does changing IORB affect the economy? Lucas: Good question. Banks have a choice: lend out their reserves or keep them at the Fed. If IORB is attractive, they'll park the money there. That reduces the supply of lendable funds, which pushes up short-term rates. So by tweaking IORB, the Fed influences the entire spectrum of money market rates, from the fed funds rate to commercial paper. Luna: And that's why the Fed has leaned on it more recently, especially when the FOMC is divided. Instead of a headline-grabbing rate hike, they can do a subtle IORB adjustment. It's like a stealth move. Lucas: Exactly. And with the core PCE price index ticking up to 130.3 in June, even though headline CPI eased to 332.6, the Fed has some justification for a bit of tightening. But with GDP growth slowing to just 1.5 percent in the second quarter, a full-blown rate hike might be too aggressive. Luna: So IORB becomes the middle ground. But how much can they actually move it without causing ripples? Is there a limit? Lucas: There is a limit, and that's where the floor system comes in. The Fed sets IORB as the top of the corridor for the fed funds rate. But if they move it too far, they could distort the money market. That's why they also use the overnight reverse repo rate as the floor. So they have a range, and IORB is the ceiling. Luna: So it's not just about setting the rate; it's about managing the entire corridor. And that's been the Fed's strategy for a while now, hasn't it? Lucas: It has, but under Warsh, they're being more deliberate about it. You see, the fed funds rate is trading at 3.63, slightly below IORB. That's typical. But the Fed is watching the spread carefully. If the spread widens, it could signal stress in the banking system. Luna: And that's what happened back in 2019, right? The repo market spiked, and the Fed had to intervene. Are we seeing any signs of that now? Lucas: Not yet. The repo market has been calm. But with the Fed's balance sheet runoff still ongoing, reserves are slowly draining. That's why IORB is so important now. It's the tool that can help manage the decline in reserves without triggering a liquidity crunch. Luna: So tying it back to the broader picture: the Fed is walking a tightrope between sticky inflation and slowing growth. IORB gives them the flexibility to nudge rates without making a big public statement. But does that flexibility come at a cost? Lucas: The cost is communication. If the Fed moves IORB without a clear explanation, markets might misinterpret it. That's why Warsh has been emphasizing the IORB as a policy tool in his speeches, almost like a 'new' instrument, even though it's been around for years. Luna: Interesting. So it's partly signaling. By highlighting IORB, they're telling markets, 'We have levers we can pull even if we don't move the headline rate.' Lucas: Precisely. And that's why, even with a divided FOMC, they can still act. It's a way to achieve a middle-ground policy without a contentious vote. The Fed's internal divide over inflation data is well known, but IORB is an area where they can find consensus. Luna: So what should we watch for in the coming months? Are there any signals that they might adjust IORB? Lucas: Look at the spread between IORB and the fed funds rate. If the fed funds rate starts to creep closer to IORB, the Fed might respond by raising IORB to maintain the floor. Also, watch the interest rate on reserve balances itself. A change there would be the clearest signal. Luna: And given that the ten-year Treasury yield is at 4.74 percent, the yield curve is steepening. That's another reason the Fed might want to keep short-term rates anchored. IORB helps with that. Lucas: Absolutely. The curve steepening is a natural outcome of the market pricing in future hikes, but by using IORB, the Fed can keep the short end stable, preventing the curve from getting too steep. Luna: So it's like a fine-tuning dial, but it's also a communication tool. That's a pretty elegant solution to a divided Fed's problem. Lucas: It is. And look, I know we talk about the big moves, but sometimes the most interesting stuff is in the details. Like this IORB adjustment. It's not going to make headlines, but it's how monetary policy actually gets implemented. Luna: And that's why we dig into it. Before we go, I just want to mention something, because if walking through the economy with us has clicked for you, there's a small way to keep this going. You can support the show at buy me a coffee dot com slash fexingo. Lucas: Yeah, that's right. It's a tiny ask, but it helps us keep this podcast ad-free and focused on the stuff that matters. No pressure, just if it's worth it to you. Luna: So back to the bigger picture: what does this mean for the average person? When IORB moves, it's not just banks that feel it. Lucas: Right. It ripples into mortgage rates, savings accounts, even credit card rates. So even a small nudge in IORB can affect your monthly payments. That's why the Fed is so careful with it. Luna: So as we watch the Fed navigate this tricky period, IORB is definitely a tool to keep an eye on. Lucas: For sure. It's not the headline, but it's the engine room. And understanding it is the real way to understand the Fed's next move.
