Exchange rate depreciation raises sectoral credit in Tanzania

What the study found: Exchange rate depreciation had a significant positive long-run effect on credit allocation across all five sectors studied in Tanzania: manufacturing, agriculture, tourism, construction, and transport and communication. The short-run effects were negative in some sectors, especially transport and communication.
Why the authors say this matters: The authors suggest these findings matter because they point to sector-specific responses to exchange rate movements, and they conclude that weaker currency conditions may support investment in the long run. They also state that the results offer policy-relevant insight for sector-specific monetary and exchange rate interventions.
What the researchers tested: The study examined how exchange rate movements, measured by both the level and first difference of the exchange rate, affected sectoral investment decisions in Tanzania. It used sectoral credit allocation as a proxy for investment and applied an autoregressive distributed lag (ARDL) model to quarterly time-series data, controlling for foreign direct investment, gross domestic product growth, and lending interest rates.
What worked and what didn't: Exchange rate depreciation was associated with higher credit allocation in the long run across all sectors. In the short run, exchange rate movements had negative effects in some sectors, particularly transport and communication, indicating that sudden currency fluctuations could disrupt sectoral financing.
What to keep in mind: The abstract does not describe limitations beyond noting that the study is based on quarterly time-series data for Tanzania and five sectors. The summary available here does not provide details on data sources, sample period, or additional caveats.
