Treasury bill yields are usually rock steady when interest rates are manipulated by the monetary authority.
In 2011 rates were manipulated by 'quantity easing' along the yield curve involving large volumes of rupee injections in to the banking system, triggering a balance of payments crisis, which required very high interest rates to fix.
However on Wednesday secondary market yields also eased, dealers said. Earlier data has shown that bank credit growth is also easing.
