The central bank will charge the repurchase rate to the government for loans extended to the maximum limit in each of the six months. The repurchase rate, currently 7.75%, is also the rate at which the central bank lends funds to banks. Loans beyond the limit will be charged an additional 2%. The government, according to an agreement with the central bank signed in March 1997, will not be allowed to keep an overdraft for more than 10 days. If loans exceed 75% of the limit, the government sells bonds to repay the funds.
