Inflows to municipal bond mutual funds ticked up this week, making it eight consecutive weeks in the red.

Funds that report their flows weekly recorded $324 million in inflows for the week of Feb. 27, Lipper FMI numbers showed. The previous week, they reported inflows of $293 million.

A surge of new issuance washed into a market thirsty for paper. Interest rose as the week progressed, demonstrated by falling yields beyond the front end of the curve. The triple-A 10-year fell nine basis points on the week to 1.81%, Municipal Market Data numbers showed. The 30-year fell three basis points and the two-year held its level over the same period, at 2.91% and 0.31%, respectively.

But tax-exempts mostly kept pace with their Treasury brethren, closing out the week from last Friday with equal parts outperformance and underperformance throughout different segments of the yield curve. As a result, muni ratios to Treasuries ended the period mostly unchanged, and still below 96% beyond the front end of the curve.

Assets for all muni funds that report their flows weekly rose this past week to $327.7 billion. The week prior, they reported $326.6 billion.

The four-week moving average for all municipal bond mutual funds that report their flows weekly was $304 million of inflows, falling slightly from $366 million the week before.
