Treasurer: Ada County portfolio yield near 3.8%; Fed cuts create reinvestment risk

Rob Brown, identified in the transcript as representing the Treasurer's Office, presented the county's November investment report and a monthly briefing on collections and upcoming fiscal tasks.

Brown told the board the portfolio's average yield-to-maturity stood at about 3.8 percent for the month. He reported total interest for the month was roughly $770,000, with $1.7 million collected year-to-date. Brown said the county's forecasted investment income for the fiscal year was $9.3 million and that the forecast had been lowered about $3 million from the prior year's projection because of recent interest-rate cuts.

Brown and the board discussed implications of a 25-basis-point Federal Reserve rate cut (the third in the recent cycle). He warned of reinvestment risk: as higher-yield investments mature, proceeds may need to be reinvested at lower rates, which could place downward pressure on future investment income. Brown noted the portfolio is positioned with relatively even maturities — roughly $46 million maturing over the next five years — which moderates but does not eliminate reinvestment risk.

Brown also briefed the board on tax-collection timing: roughly 45 percent of the first-half tax amount had been collected, with a due date of Dec. 22; staff expect mortgage-servicer wires to accelerate collections in the final days.

The board thanked Brown for the report and asked clarifying questions about liquidity vehicles such as the state LGIP and diversified bond fund holdings; Brown explained those instruments and their liquidity profiles.
