The key factor to attract lenders in the European monetary loan market is the small spread. European money market spreads are small, deposit interest rates are slightly higher than domestic deposit interest rates in currency issuing countries, and loan interest rates are lower than domestic loan interest rates. The most important factors affecting the supply and demand of money are the motivation of depositors to pursue the highest income and the motivation of borrowers to pursue the lowest cost. Because European banks are not restricted by deposit reserve and interest rate ceiling, they can absorb deposits at higher interest rates and lend at lower interest rates.
