This series reads 22.04; the same figure from the other source reads 23.84. Compared with

T-bill 12M end-of-period yield (table4.04) vs nearest weekly primary-market yield (2022-06-24)
LK.DEBT.TBILL.TBILL_12M_YIELD_EOP.M, 2022-06: end-of-period reading 23.84% vs nearest weekly primary auction 22.04%, diff +1.80pp. Genuine yield movement between the auction date and the table's own end-of-period reading, larger than the check's 1pp tolerance; only 10 of ~750 compared periods fall outside the band (~1.3%).
