Low interest rates, coupled with escalating housing prices, are the key drivers of growing household debt. In this context, monetary tightening may play an opposite role to conventional monetary policy. Moreover, inordinate indebtedness likely acts as a deterrent to household consumption. Using threshold regression, this study explores the nonlinear nexus between monetary policy and household debt, as well as the nexus between household consumption and debt in Korea. The results reveal that an increase in the monetary policy rate boosts household debt in a regime with values beyond the threshold of the nominal (real) housing sales price index approximately 61.3 and 63.9 (80.7) for regressions on the regime-specific nominal and real policy rates, respectively. This implies that monetary tightening can enhance household debt due to high housing price expectations. Furthermore, an increase in household indebtedness suppresses household consumption when the household debt-to-annual GDP ratio is above the thresholds of approximately 84% and 82% for regressions on household debt growth and household debt-to-GDP ratio growth, respectively. These findings suggest that, under low interest rates, in the face of high housing prices and “excessive” household indebtedness, monetary tightening and debt expansion are unviable courses of action for resolving growing household indebtedness and declining household consumption. Therefore, when regulating the policy rate to control household debt and spending effectively, it is crucial to maintain housing prices and household indebtedness at desirable levels. In tandem with this, additional policy instruments such as macroprudential and housing-related fiscal regulations may also be needed to attain financial stability.</div></div>","PeriodicalId":43998,"journal":{"name":"Central Bank Review","volume":"25 1","pages":"Article 100190"},"PeriodicalIF":2.0,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143422625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given its significant contribution to employment, exports and national income, agricultural production-climate change relation is considerably crucial for the Turkish economy. In this paper, we investigate the impact of climate change on wheat production at the province-level with a unique, up-to-date and comprehensive dataset that is constructed by the Central Bank of the Republic of Türkiye (CBRT) under the Early Warning System Project (EWSP). In the corresponding models, climate change is initially considered in a conventional way via temperature and precipitation measures, later considered with new alternative composite climate indicators. The estimation results obtained from models with two different alternative climate measures are comparable and similar: Climate change has a statistically significant adverse impact on wheat production. Combining model estimation results with the climate scenarios, the impact of hotter springs and summers on wheat production for different time spans has been put forward. The impact is found to be increasing over time, regardless severity of the climate scenarios. We believe that our understanding regarding climate change-agricultural production relation will improve with the advancements of the data set, and this will support the development of more efficient policy recommendations.</div></div>","PeriodicalId":43998,"journal":{"name":"Central Bank Review","volume":"25 1","pages":"Article 100191"},"PeriodicalIF":2.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investigation is based on a structural vector autoregression model, where sector-specific real credit card spending data (adjusted for inflation) representing an overall country, Türkiye, are used. The empirical results (in the long run) suggest that a positive shock to the monetary policy rate reduces real credit card spending in cars, health, insurance, and shopping in a statistically significant way, whereas it increases real credit card spending on airlines and travel. Monetary policy shocks contribute to the volatility of credit card spending by up to 36% for insurance, 26% for markets and shopping centers, and 22% for travel sectors, whereas this contribution is only about 3% for contractor services and about 4% for car rentals, jewelry, and casino sectors. It is implied that there are uneven effects of monetary policy across sector-specific credit card spendings. These results are robust to the consideration of changes in unemployment rate, inflation rate, nominal effective exchange rate, and the number of credit card transactions as well as alternative model specifications with different numbers of lags, different variables, and different estimation strategies.

Given that Kazakhstan is highly sensitive to adverse external fluctuations (due to its economic structure), our empirical strategy investigates asymmetric dynamics of prices of goods with high versus low degree of import share. Hence, we develop a methodology to determine the level of “importability” in certain consumption products, which serves as a proxy of vulnerability to external macroeconomic shocks. The results confirm our hypothesis that products with different degree of import content respond differently to major macroeconomic shocks. Consequently, we conclude that headline inflation in Kazakhstan is primarily impacted by supply-side factors, such as the direct transmission of exchange rate changes to prices of products with higher import shares (exchange rate pass-through) and a large component of inflation inertia. Differentiating and properly identifying inflation dynamics of the high-import-content and low-import-content goods have important implications for optimal monetary policy conduct in developing economies.</div></div>","PeriodicalId":43998,"journal":{"name":"Central Bank Review","volume":"24 4","pages":"Article 100179"},"PeriodicalIF":2.0,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142530804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prudential data at country-level was used to estimate the level of banks' voluntary management buffers, which were found to be significant overall (although gradually decreasing) and enough to accommodate the introduction of the nCCyB. According to estimations, introduction of the nCCyB at those rates would have reduced banks’ management buffers on average by 6.5–26.0%. However, there is visible heterogeneity among EU countries. The resulting lowest decrease in capital headroom following the potential introduction of the nCCyB was recorded, among others, in Sweden, Czech Republic, Slovakia, Malta, Ireland, with the highest in Spain, Croatia, Greece, and Austria.
