Another week, another new record for money market fund assets.

Inflows to US money funds decelerated in the week to August 9, data released late Thursday showed. Nevertheless, a $14.37 billion haul marked the fourth straight weekly influx and the fifth in six.

Total assets now stand at $5.53 trillion.

The data covers the week following Fitch’s decision to downgrade America’s credit rating. Nearly half of the inflow was attributable to retail prime funds. $3.64 billion flowed into institutional government, a modest take.

It’s the same story week after week: Yields are attractive compared to many bank savings products, and although just $4.3 billion of this week’s haul went to government funds, the facts are the facts, and no ratings agency can change them: US government money market funds are as safe as investments get. Safer in some respects than an FDIC-insured bank account.

Treasury ramped up bill issuance in the wake of last week’s refunding announcement and although some analysts remain concerned about oversupply, the money market fund sponge is fully capable of absorbing more — it’s just a matter of coaxing money out of the Fed’s RRP facility and into bills.

Notably, dealer bill inventories were down to $54.8 billion in the week to August 2, the latest data showed.

That’s the least since the debt ceiling was suspended and down from a record $116 billion early last month. There was $1.759 trillion parked in the Fed’s RRP facility on Thursday.

Meanwhile, borrowing from the Fed’s Bank Term Funding Program (the backstop created in the wake of SVB’s implosion in March) hit yet another new record in the week to August 9.

Usage is up five weeks in a row and now stands at $106.864 billion. Discount window borrowing rose slightly.

The total between both facilities stood at $108.775 billion. That figure has increased in 13 of the last 14 weeks.
