Money market funds typically get little coverage in the financial press because, except under extreme circumstances, they don't rise or fall in value. Boring! But that's about to change, as new rules will soon require institutional prime money market funds to report their real-time market value and hold more liquid assets. Many worry this will dry up short-term funding markets, as money market funds are one of the primary investors in commercial paper. Sure enough, Libor rates have risen lately, driving fears of "stealth tightening" in credit markets. While the nervousness is understandable, it's unlikely major turmoil lies ahead.
The London Interbank Offered Rate, better known as Libor, is the average rate banks pay to borrow from each other over short time periods. It is also the reference rate for many bank loans-hence why people are worried about the apparent spike. The volatility is quite simple to trace to the money market fund reforms, which take effect on October 14. Money market funds have long invested in commercial paper for its yield (which exceeds T-bills), offering investors a way to hold "cash" with a higher return than a plain old bank deposit. But the looming rule changes will require prime institutional money market funds to have floating net asset values instead of being fixed at $1 / share-regulators' attempt to prevent a repeat of the panic that ensued when one huge money market fund "broke the buck" in 2008, triggering a run on money market funds.[i] The rules also impose liquidity requirements and tighter restrictions on portfolio holdings, and many fund providers have decided to switch from prime funds to funds that invest primarily in government debt, which regulators treat with more leniency. As a result, banks and other firms that issue commercial paper have had to raise rates a tad to attract buyers.
Yet there is a large gap between incrementally higher funding costs due to a structural change in the marketplace and an actual, acute funding squeeze. For one thing, despite the clamor, Libor remains low by historical standards. (Exhibit 1)

Rates were much higher from the mid-1980s through 2007, both during good times and bad. Libor routinely topped 5% in the mid- and late-1990s, when credit was plentiful. Rates rose quite a bit in the few years leading up to 2008's financial crisis, but this is coincidental, not causal, as the crisis had a completely unrelated culprit. Short rates, whether Libor or otherwise, are only one input into credit supply. Long rates matter too, and all banks really need is a sufficient spread between the two.
Jitters about demand for commercial paper are also a bit myopic. For one, they overlook that supply has also plunged-these rules were a long time coming, and firms adapted.

Firms have other ways of funding cash needs, and they've already been doing this in greater numbers since the global financial crisis. For one, they can issue more bonds.

They can also hold more cash, which they've also been doing more of in recent years. According to the Federal Reserve, non-financial corporations held a record $1.9 trillion in cash in 2015. Additionally, since the financial crisis, regulators have nudged banks to rely less on wholesale funding (which includes commercial paper), perceiving traditional deposits as more stable-further limiting supply. Banks have also amassed piles of excess reserves since 2008 as the Fed injected trillions into the banking system. (Exhibit 4).

All that said, there are implications for investors. In advance of the new rules, many fund companies closed prime funds or switched the default cash reserves fund to government money market funds, which have lower yields. It's possible more changes lie ahead, so you may want to check with your broker-dealer to see if your options have changed. Also, investors in institutional prime money market funds-which include many 401(k) participants-will soon see these funds fluctuate in price. At times the price may dip below $1 / share (and at times it might go a wee bit higher). Money market funds should remain a perfectly viable cash-like option-just as they have since that one isolated issue in 2008. People are already aware money markets can go below $1 and haven't stayed away.
[i] The irony here is that the big fund that broke the buck in 2008 was a retail fund, not an institutional fund, and its NAV therefore floated, which is how it broke the buck. And people panicked. So we mostly fail to see how requiring everyone to float would make these securities somehow less prone to a run. But it does level the playing field and add transparency, forcing these funds to own up to the fact that they are all short-term debt funds.
