Laurence Bristow on What the Fed can Learn from the Reserve Bank of Australia

Episode Summary

Executive Summary: In this episode of Macro Musings, host David Beckworth interviews Lawrence Bristow, a former Reserve Bank of Australia (RBA) staffer, about the RBA's transition to a demand-driven ceiling system for monetary policy implementation. They discuss the motivations behind the review, the system's design, and its implications for the Federal Reserve. Bristow explains how the RBA's new system allows banks to determine reserve quantities, reducing uncertainty and stigma, while maintaining control over interest rates. The conversation also covers challenges like stigma at the Fed's standing repo facility and the need for robust ceiling facilities.

Main Topics: RBA's Monetary Policy Implementation Review (Priority: 5/5): The RBA conducted a multi-year review (2022-2025) to transition from a scarce reserve regime to a demand-driven ceiling system, prompted by the expansion and subsequent decline of reserves from COVID-era policies. Demand-Driven Ceiling System Design (Priority: 5/5): The new system features a ceiling facility (open market operations once a week) and a roof (overnight standing facility) to cap rates, with a spread of 20 basis points above the interest on reserves to encourage interbank activity. Comparison with Other Central Banks (Priority: 4/5): The RBA's approach differs from the Bank of England's demand-driven floor system (zero spread) and the ECB's demand-driven floor system, highlighting varying degrees of opportunity cost for holding reserves. Challenges with the Fed's Current System (Priority: 4/5): The Fed faces stigma at its standing repo facility and discount window, with repo rates recently rising above the interest on reserves, indicating a need for better ceiling facilities. Regulatory and Supervisory Intersection (Priority: 3/5): Governor Stephen Moran's speech highlighted how bank supervision (e.g., liquidity requirements) can conflict with monetary policy implementation, a dynamic also seen in Australia. Uncertainty in Reserve Demand (Priority: 4/5): The difficulty of estimating reserve demand in an ample reserve system, as seen in the Fed's September 2019 repo spike, motivates the shift to demand-driven systems where banks self-select.

Key Arguments: Demand-driven ceiling systems reduce uncertainty by letting banks determine reserve quantities, avoiding the need to forecast reserve demand. A small spread (e.g., 20 bps) between the ceiling rate and interest on reserves incentivizes interbank lending and price discovery, unlike a floor system with zero spread. Stigma at the Fed's standing repo facility can be reduced by recasting its purpose, moving auctions earlier, or separating bank and dealer participation. Central clearing for the standing repo facility could expand access to non-bank entities but may increase systemic risks. The RBA's system provides 'latently ample liquidity'—banks can always borrow at the ceiling, avoiding the need for large reserve buffers. A demand-driven system requires robust ceiling facilities and may need more frequent operations if reserves are very scarce.

Data Points: RBA's foreign reserves portfolio size: $60 billion Australian dollars - Managed across seven currencies for market intervention. Spread of RBA's ceiling facility over interest on reserves: 20 basis points (increased from 15 bps in April 2025) - To encourage interbank activity and reduce the RBA's balance sheet footprint. RBA's share of the repo market in scarce reserve system: 30% - Even with only $2-3 billion of reserves injected, highlighting a large footprint. Potential reserve injection under demand-driven system: Up to $200 billion - Estimated by the RBA, prompting concerns about balance sheet size. Duration of RBA's framework review: 3 years (2022-2025) - First stage decided the system type; second stage detailed the design. Frequency of RBA's open market operations: Once a week (Wednesdays) - Creates intra-week volatility managed by the overnight standing facility.

Pivotal Quotes: "I think the biggest motivation for switching to a demand-driven ceiling system is that during the country's experience with the floor system, they found out that the demand for reserves is highly uncertain, it's difficult to estimate, and you can run up against the steep part of the demand curve without knowing that it's going to happen." — Lawrence Bristow: Explaining why central banks are moving to demand-driven systems, citing the Fed's September 2019 repo spike as a cautionary tale. "One of the things that the RBA has done as part of its announcement of its new system is it's released a joint statement with the Australian Prudential Regulatory Authority that says we want banks to use the overnight standing facility in the regular course of business, and we won't kind of think badly of banks for doing that because it's important for the RBA's control over monetary policy." — Lawrence Bristow: Describing efforts to reduce stigma at the overnight standing facility, a key component of the ceiling system. "I think the thing that's nice about the ceiling system is that banks know they can borrow from the Reserve Bank at their ceiling system if they need liquidity. And that, if it's priced appropriately, means that banks generally have enough cash to operate." — Lawrence Bristow: Highlighting the advantage of latent ample liquidity in a demand-driven ceiling system.

Implications: The RBA's shift to a demand-driven ceiling system offers a blueprint for the Fed to reduce balance sheet costs and improve monetary control. Key lessons include designing stigma-free ceiling facilities and allowing modest volatility for price discovery. The Fed may need to enhance its standing repo facility and consider central clearing to address current money market strains.
