New report outlining how we used text embeddings to categorize >30 million products of the ECB's daily price dataset in a cost-efficient manner. The goal is to turn billions of prices into snapshots of current inflation: www.bis.org/publ/othp109...

Heterogeneity & Inflation: From Microeconomic Variation to Macroeconomic Impact

The BIS Innovation Hub Eurosystem Centre and the BIS Monetary and Economic Department, in association with CEPR, CEBRA and Basel University is organising a conference on Inflation Heterogeneity: Micro-Level Variations and Macro-Level Effects. The conference will take place 26-27 May 2026 at the BIS in Basel, Switzerland.

This conference will explore different dimensions of heterogeneity - across consumers, firms, and shocks - and the resulting macroeconomic implications for aggregate inflation and policy. It will also explore the practical implications for the measurement, nowcasting and forecasting of inflation, including projects such as Spectrum of the BIS Innovation Hub. The conference is aimed at both academic and policy audiences.

Scientific Committee: Raphael Auer (BIS & CEPR), Boris Hofmann (BIS), 
Sarah Lein (University of Basel & CEPR), Chiara Osbat (ECB), Elvira Prades (BIS & Banco de EspaΓ±a), Andras Valko (BIS) and Henning Weber (Bundesbank).

Deadline: 15 March 2026

Job alert: my current role. After 4 rewarding years leading the Eurosystem Centre, I’ll be moving back into a research role early next year. We’re also re-opening the search for the Nordic Centre Head β€” both applications close October 14:

How economically significant is decentralized finance (#DeFi)?

... #TVL can be inflated due to double-counting and reliance on off-chain data. We hence introduce Verifiable TVL, a more transparent and reproducible approach to measuring DeFi’s scale:

DeFiying gravity? An empirical analysis of cross-border Bitcoin, Ether and stablecoin flows We investigate trends and drivers of cross-border flows of the two major native cryptoassets (Bitcoin and Ether) and the two major asset-backed stablecoins (Tether and USD Coin) between 184 countries ...

Here's a new report from the Bank for International Settlements, showing the reality of digital assets with actual data.

Yes, most activity is pure speculation. BUT, there is legitimate transactional cross-border usage of stablecoins.

Distributed ledgers are the embodiment of the vision of a decentralised notion of money. The key idea is to harness a network of self-interested β€˜validators’ to perform the record keeping role of trusted intermediaries that underpin our current monetary system. This column examines the economic trade-offs in designing such systems, focusing on the interplay between decentralisation, finality, and scalability. A well-designed decentralised system aligns the interests of market participants with ledger maintainers. However, replicating validation across numerous validators can be cost-effective only in low-trust environments.

@raphauer.bsky.social, Cyril Monnet, & Hyun Song Shin discover that the economic gains from decentralisation of monetary ledgers are far from self-evident. One must balance decentralisation, security, and scalability.
