The Fed stated that it will increase the frequency of dollar swap lines with the European Central Bank and Bank of Japan, as well as the Bank of England, Bank of Canada, Bank of Canada, Bank of Canada, Bank of Canada, Bank of Canada, Bank of Canada, Bank of Canada, Bank of Canada, and Swiss National Bank from weekly, to daily, beginning Monday. Dollar swap lines are a way for foreign central banks to borrow U.S. dollar while protecting the Fed against downside risks. A swap is where a foreign central bank exchanges its currency for a similar amount of U.S. dollar from the Fed at the current exchange rate. The bank repays the Fed with interest the dollars that it has borrowed after a time.
