Explanation:
Debt Covenants becoming more restrictive means that less people want to borrow money. This shifts the demand curve to the left and this Decreases interest rates.
The Fed increasing money supply means that there is more money in the economy. This shifts the supply curve to the right thus having the effect of reducing Interests rates as there is more money available for loans.
Total Household Wealth increasing means that Households have less of an incentive to borrow money. This reduces the demand for interest rates so interest rates decrease.
