6-Month T Bills reach double-digit levels after 87 weeks
This week's T Bill auction crossed an important threshold. 182-day weighted average yield closed at 10.01% - for the first since 03 Oct 2024. The 364-day also crossed over, finishing at 10.02%.
Pace of yield increases has slowed. However, this is because we saw a sharp adjustment last week, following Central Bank of Sri Lanka policy rate hike.
• 91 days: +48 bps → 9.84% → 85% accepted
(vs +118 bps → 110% last week)
• 182 days: +33 bps → 10.01% → 84% accepted
(vs +143 bps → 32% last week)
• 364 days: +19 bps → 10.02% → 48% accepted
(vs +134 bps → 33% last week)
Acceptance levels have recovered. 182-day fill rate jumped from 32% to 84% - proving that investors are drawn at the right yield.
However, overall auction acceptance levels still remain below 100% - a bid-to-cover of 1.52x with 79% overall fill rate.
Crossing the 10% threshold is a psychological marker more than a technical one.
But it reminds us how far rates have moved in a short period. 182-day was at 8.25% on 20th May 2026, i.e. a 176 bps spike in just two weeks.
