Treasury Certificates (TC)

  • The Treasury of the Kingdom of Belgium issues, in principle, twice a month on a Tuesday, Treasury Certificates at 3 and 6 or at 3 and 12 months by means of competitive bidding.
  • Auctions for Treasury Certificates are based on the interest rates offered by the bidders.
  • Bids must be at least EUR 10 000 000 and a multiple of EUR 1 000 000.
  • The Treasury determines a limit rate. All bids submitted at rates lower than this limit rate are allocated for their full amount.
  • Allocations in response to bids submitted at the limit rate chosen by the Treasury may be proportionally scaled down. The amounts thus reduced are rounded up to the next tranche of EUR 1 000 000 with a minimum of EUR 10 000 000 per bid.
