Same firms, different footprints: making sense of financed emissions

Lewis Holden

Over 95% of banks’ emissions are ‘financed emissions’. These are indirect emissions from households and businesses who banks lend to or invest in (banks’ asset exposures). Banks disclose these in line with regulations designed to help markets understand their exposure to climate-related risks and their impact on the climate. But emissions disclosures vary drastically between different banks with similar business models. Data quality and availability is cited as the key reason for this. In this post, I demonstrate that variations in financed emissions estimates are explained by the extent of banking activities and asset exposures rather than data quality and availability. For example, whether estimates capture a subset of loan exposures or wider banking activities such as bond underwriting.

The gathering swarm: emergent AGI and the rise of distributed intelligence

Mohammed Gharbawi

Rapid advances in artificial intelligence (AI) have fuelled a lively debate on the feasibility and proximity of artificial general intelligence (AGI). While some experts dismiss the concept of AGI as highly speculative, viewing it primarily through the lens of science fiction (Hanna and Bender (2025)), others assert that its development is not merely plausible but imminent (Kurzweil (2005); (2024)). For financial institutions and regulators, this dialogue is more than theoretical: AGI has the potential to redefine decision-making, risk management, and market dynamics. However, despite the wide range of views, most discussions of AGI implicitly assume that its emergence will be as a singular, centralised, and identifiable entity, an assumption this paper critically examines and seeks to challenge.

When mortgage flexibility meets monetary policy tightening: heterogeneous impacts on spending and debt

Philippe Bracke, Matt Everitt, Martina Fazio and Alexandra Varadi

The Bank of England Agenda for Research (BEAR) sets the key areas for new research at the Bank over the coming years. This post is an example of issues considered under the Macroeconomic Environment Theme which focuses on the changing inflation dynamics and unfolding structural change faced by monetary policy makers.

How do mortgagors adjust spending, savings and debt during monetary tightening? In a recent paper, we explore this question using a novel data set on household transactions and mortgage records. About 30% of households used mortgage flexibility when facing higher borrowing costs since late 2021, as their fixed-rate contracts ended. Some extended repayment periods to lower monthly payments, while others increased borrowing by extracting housing equity – leveraging nominal price gains since the pandemic – to sustain spending and reduce unsecured debt. Those unable or unwilling to use mortgage flexibility, cut spending significantly. We thus document the dual role of mortgage flexibility at refinancing: it helps smooth consumption aiding financial resilience; but it may also dampen monetary policy transmission for some households.

Muddled measurements on clarity

Charlie Warburton and James Brookes

Economists have repeatedly shown that readability of central banking communication matters. But they typically measure readability in a crude way – using the simplistic but influential Flesch-Kincaid metric. The Flesch-Kincaid Grade Level is based on word and sentence length and is commonly interpreted as the number of years of education required to understand a text. However, recent advances in computational linguistics toolkits empower us to consider finer-grained markers of language comprehension missed by Flesch-Kincaid. Here, we revisit Jansen (2011) which found that Fed Chair testimonies with lower Flesch-Kincaid Grade Level scores – indicating higher readability – were associated with lower market volatility. Our results show that compared to more sophisticated linguistic metrics, Flesch-Kincaid is a relatively poorer indicator of readability.

What happens to inflation when we put a price on carbon?

Hannah Copeland, Lennart Brandt, Natalie Burr and Boromeus Wanengkirtyo

Emissions Trading Schemes (ETS) are an increasingly popular market-based policy to impose a price on carbon emissions (previously costless to the emitter) (World Bank Group (2025), DESNZ (2025)). With carbon prices expected to increase steadily, and sectoral coverage broadening, these schemes have gained the attention of monetary policy makers (Breeden (2025), Mann (2023)). But what are the implications for inflation? By constructing a new tool (a high-frequency identified ‘instrument’) to measure the impact of supply shocks in the UK carbon market, we document that a tighter carbon pricing regime temporarily increases energy prices and inflation, and decreases output. We find that this shock transmits through multiple energy-related commodity prices, including oil and gas, compounding cost-push pressures arising from the energy sector.

Once upon a time in the future: strategic foresight in central banks

Julia Giese and Jacqueline Koay

We live in an era of rapid change, complexity and uncertainty. Over recent years, severe global shocks have been frequent, with profound implications for our economy and financial system. Yet such shocks are impossible to forecast with any precision as they are not extrapolations of past relationships. Our economy and financial system are subject to longer-running trends such as technological advances, demographics, geopolitical shifts and climate change which can be blown off course or altered in unexpected ways. Where forecasts are bound to fail, strategic foresight tools can help as they are a means for practitioners to understand the dynamics of change (and how this could impact the economy and financial stability) by imagining different futures and telling stories around how trends might interact to give rise to unforeseen shocks.

How fixed are global exchange rates?

Roger Vicquéry and Kevin Hjortshøj O’Rourke

While the collapse of the Bretton Woods system in 1973 has traditionally been seen as heralding a major shift towards floating exchange rates, the extent of this transition away from fixed arrangements has been called into question by a ‘New Consensus’ view. We provide a new index to measure exchange rate fixity at the global level, which restores the conventional account of international monetary history over the last 70 years: according to our measurement global exchange rate fixity is now only about a third of its Bretton Woods level. We highlight how this transition to floating arrangements was largely driven by anchor currencies ceasing to be pegged to one another.

More mortgage lending might push home ownership further out of reach

Jamie Waddell and Danny Walker

Would expanding mortgage supply lead to increased home ownership? Given that 90% of young home owners have a mortgage, it’s tempting to assume the answer is yes. But our analysis suggests that assumption is not necessarily true. We show that increases in mortgage supply have historically had no discernible effect on the home ownership rate and instead tend to push up on house prices, which makes it harder for first-time buyers (FTBs) to afford their first home. They also tend to divert lending towards home-movers and there is some evidence that they increase rents too.

Collateral re-use: unveiling the risk of delivery failures and higher volatility in the repo market

Miruna-Daniela Ivan

The widespread practice of financial institution to re-use securities received as collateral plays a key role in the repurchase agreement (repo) market functioning. By increasing the availability of securities which can be used as collateral, collateral re-use lowers funding costs under normal market conditions, allowing collateral to flow to where it is most needed. But this activity may amplify the risk of delivery failures and increase volatility in repo rates during periods of market stress. This article explores the level of collateral re-use in the gilt repo market, applying algorithms from academic literature to the Bank’s Sterling Money Market Data, and provides supporting evidence of collateral re-use procyclicality, and its positive relation to repo rates volatility.

Could digitalisation of finance lead to more disruptive international capital flows?

Simon Whitaker

Digital currencies and the tokenisation of financial assets could speed up the movement of money and assets between institutions and across borders. Historically, the liberalisation of capital flows led to debates about the impact on macroeconomic and financial stability. Bouts of instability – for example the 2008 global financial crisis – provoked calls to put ‘sand in the wheels’ of financial markets. In this blog I argue there is no reason why lubricating capital flows through digitalisation should herald a new era of financial instability. But the architecture of the global financial safety net may need to evolve to contain risks to the international monetary and financial system.
