The 182-day bill saw limited interest, with just GH¢622.79 million in bids.
Meanwhile, interest rates continued their downward trend across the yield curve.
The 91-day bill dropped by 14 basis points to 14.56%.
While the 364-day bill posted the sharpest fall, tumbling by 58 basis points to 15.16%, that of the 182-day yield also declined to 15.01%, from 15.25% the previous week.
Market watchers say, attribute the soft performance to investors seeking better returns amid tightening liquidity and a preference for Bank of Ghana instruments, which offer comparatively more attractive yields.
