What this means for KES 100,000
Worked from the published rate · information, not advice
KES 7,698 in 12 months on the 364-day bill, after tax
Put KES 100,000 into the 364-day bill at this auction and you get back KES 107,698 after 12 months: KES 7,698 in interest after 15% withholding tax (KES 9,057 before), about KES 642 a month.
That is KES 8 less than the same money would have earned at the previous auction.
For shorter money: KES 3,787 on the 182-day bill (6 months), KES 1,867 on the 91-day bill (3 months).
The Central Bank’s minimum bid is KES 100,000, and the government pays the full amount at maturity; the risk is Kenya’s government not paying, and the money is locked until then.
Kwa Kiswahili
Ukiweka KES 100,000 kwenye hati ya siku 364 kwa riba ya mnada huu, utarudishiwa KES 107,698 baada ya miezi 12: riba ya KES 7,698 baada ya kodi ya zuio ya 15% (KES 9,057 kabla ya kodi), yaani takriban KES 642 kwa mwezi.
Hiyo ni KES 8 pungufu ya kiasi ambacho pesa hiyo hiyo ingepata kwenye mnada uliopita.
Kiwango cha chini cha Benki Kuu ni KES 100,000. Serikali hulipa yote mwishoni mwa muda; hatari ni serikali kushindwa kulipa, na pesa haipatikani hadi muda uishe.
