Banks’ Joint Exposure to Market and Run Risk
Description: Recent failures of US banks highlight that large liability withdrawals can damage capital positions—i.e., that liquidity risk and solvency risk interact. A simple risk assessment for banks in a wide group of countries finds sizable exposure to this interaction. This varies significantly across banks—primarily reflecting differences in cash buffers, capitalization, securities holdings and exposure to market risk—and is highly concentrated. Vulnerability is generally greater for banks in AEs due to lower cash buffers, securities holdings and capitalization. Within AEs—unlike in EMs—larger banks are most exposed, due to greater wholesale funding and thinner capital buffers. Estimated aggregate losses are substantial in some countries, reflecting a range of recent shocks.

The Market Price of Risk and Macro-Financial Dynamics
Description: We propose the conditional volatility of GDP spanned by financial factors as a “Volatility Financial Conditions Index” (VFCI) and show it is closely tied to the market price of risk. The VFCI exhibits superior explanatory power for stock and bond risk premia compared to other FCIs. We use a variety of identification strategies and instruments to demonstrate robust causal relationships between the VFCI and macroeconomic aggregates: a tightening of financial conditions as measured by the VFCI leads to a persistent contraction of output and triggers an immediate easing of monetary policy. Conversely, contractionary monetary policy shocks cause tighter financial conditions.

Financial Shock Transmission to Heterogeneous Firms: The Earnings-Based Borrowing Constraint Channel
Description: We study the heterogeneous impact of jointly identified monetary policy and global risk shocks on corporate funding costs. We disentangle these two shocks in a structural Bayesian Vector Autoregression framework and investigate their respective effects on funding costs of heterogeneous firms using micro-data for the US. We tease out mechanisms underlying the effects by contrasting traditional financial frictions arising from asset-based collateral constraints with the recent earnings-based borrowing constraint hypothesis, differentiating firms across leverage and earnings. Our empirical evidence strongly supports the earnings-based borrowing constraint hypothesis. We find that global risk shocks have stronger and more heterogeneous effects on corporate funding costs which depend on firms' position within the earnings distribution.

Estimation and Determinants of Cost Efficiency: Evidence from Central Bank Operational Expenses
Description: The finances of central banks is a topic of renewed interest: many central banks are posting significant losses due to the cost of monetary policy, over which central banks have no control. Conversely, operational expenses, over which the central banks have more control, is a subject of less attention. We use public income statement data from central banks to calculate a score for operational expense efficiency based on a stochastic frontier analysis. In addition, we offer potential explanations for the observed variations in efficiency levels across central banks. Our analysis reveals significant heterogeneity across countries and income groups. Central banks with a single objective demonstrate higher efficiency compared with those with multiple objectives. Regarding the output of price stability, central banks in low-income developing countries exhibit lower efficiency compared with central banks in emerging markets and advanced economies. Factors such as central bank independence, the depth of the financial system, and the degree of openness play a role in influencing efficiency levels. Our findings underscore the significance of well-defined objectives, the operating environment, and concentration on core activities in reducing inefficiency.

Cryptocarbon: How Much Is the Corrective Tax?
Description: With increasing awareness of past environmental damage from crypto mining, questions arise as to how persistent the problem will be in the future and how taxation can help in addressing this negative externality. We estimate that the global demand for electricity by crypto miners reached that of Australia or Spain, resulting in 0.33% of global CO2 emissions in 2022. Projections suggest sustained future electricity demand and indicate further increases in CO2 emissions if crypto prices significantly increase and the energy efficiency of mining hardware is low. To address global warming, we estimate the corrective excise on the electricity used by crypto miners to be USD 0.045 per kWh, on average. Considering also air pollution costs raises the tax to USD 0.087 per kWh. Country-specific estimates vary depending on their electricity sources.

The Financial Cost of Using Special Drawing Rights: Implications of Higher Interest Rates
Description: Since the August 2021 SDR allocation, the SDR interest rate has risen about 390 basis points through end-June 2023. This paper analyzes the impact of higher SDR interest rates on IMF members with negative net SDR Department positions. To do so, it constructs SDR forward curves at different points in time, from which the expected cost of servicing SDR obligations can be compared. Results show that the expected path of the SDR interest rate has shifted significantly upward since the 2021 allocation. Expected costs of charges (interest) in net present value terms are estimated to have more than tripled, while the grant element of SDRs has fallen to just below the IMF’s concessionality threshold. Despite this increase in cost, IMF members’ capacity to service SDR obligations remains generally adequate in both baseline and stress scenarios, though a few countries will need to carefully manage the rise in interest costs. Decisions to convert SDRs should consider interest rate risks, among other country-specific factors.

The Zombie Lending Channel of Monetary Policy
Description: We uncover a new channel—the zombie lending channel—in the transmission of monetary policy to nonfinancial corporates. This channel originates from the presence of unviable and unproductive (zombie) firms. We identify exogenous variation in monetary conditions around the world by exploiting the international transmission of US monetary policy shocks. We find that tighter monetary policy leads to more favorable credit conditions for zombie firms relative to other firms. Zombies are then able to cut investment and employment by relatively less. This is indicative of evergreening motives by lenders when interest rates rise: lenders face incentives to restructure existing loans of zombie firms to avoid the realization of losses on their balance sheets. Policies that strengthen banks’ balance sheets, that limit banks’ incentives to engage in risky behavior, and laws that allow an efficient resolution of weak firms, may help mitigate zombie lending practices when financial conditions tighten.

ASEAN-5: Further Harnessing the Benefits of Regional Integration amid Fragmentation Risks
Description: The ASEAN-5 region, which comprises Indonesia, Malaysia, the Philippines, Singapore, and Thailand, has benefited substantially from its integration to the world economy, particularly through trade. Rising risks of geoeconomic fragmentation could reverse some gains reaped from globalization over the past decades. In this context, advancing regional integration among ASEAN-5 members has the potential to enhance the region’s resilience against external headwinds. This paper shows that despite sizeable progress, particularly in regional trade integration, there is room to advance financial integration, which also lags trade integration in ASEAN-5. Empirical findings from the paper illustrate that a higher degree of regional financial integration could generate sizeable output gains for the region. Using firm-level data, the paper highlights that digitalization, an area where the region is thriving, can support regional integration by helping firms better integrate into global value chains, with the benefits being stronger for small and medium sized enterprises. The results also suggest that digitalization can help firms move up the value chain through the production of more sophisticated products, often coined as higher export sophistication.

One Hundred Inflation Shocks: Seven Stylized Facts
Description: This paper identifies over 100 inflation shock episodes in 56 countries since the 1970s, including over 60 episodes linked to the 1973–79 oil crises. We document that only in 60 percent of the episodes was inflation brought back down (or “resolved”) within 5 years, and that even in these “successful” cases resolving inflation took, on average, over 3 years. Success rates were lower and resolution times longer for episodes induced by terms-of-trade shocks during the 1973–79 oil crises. Most unresolved episodes involved “premature celebrations”, where inflation declined initially, only to plateau at an elevated level or re-accelerate. Сountries that resolved inflation had tighter monetary policy that was maintained more consistently over time, lower nominal wage growth, and less currency depreciation, compared to unresolved cases. Successful disinflations were associated with short-term output losses, but not with larger output, employment, or real wage losses over a 5-year horizon, potentially indicating the value of policy credibility and macroeconomic stability.

When Will Global Gender Gaps Close?
Description: On the current pace of reforms, global gender gaps are estimated to close, using deterministic (linear or log-linear) trends, over the next three centuries. This means that many women will likely not be able to fully use their abilities and talents, to the detriment of societies, for a long time. Yet this paper shows that, absent a significant step up in policy efforts, gender gaps may in fact never close. Using Markov chains, a common approach in macroeconomics, this paper analyzes the dynamics of the cross-country distribution of the gender gap in labor force participation. This methodology does not impose strong restrictions on the data, allowing for episodes of progress as well as regress by countries on gender inequality. Based on the experience of the past three decades, the analysis predicts a further narrowing of gender gaps over time. But the long-run distribution of gender gaps in labor force participation features a substantial share of countries with persistently large gaps, implying that—absent a strengthened and systematic policy effort—some of the current misallocation of women’s talents and abilities could persist perpetually.
