Query: Why I cannot find a “Pure Cash” option in 401k investments?

Relevant passages:
 <=SEP=> "Holding pure cash is a problem for 401K companies because they would then have follow banking rules because they would be holding your cash on their balance sheets. They don't want to be in that business. Instead, they should offer at least one option as a cash equivalent - a money market fund. This way the money is held by the fund, not by 401K administrator. Money Market funds invest in ultra-short term paper, such as overnight loans between banks and other debt instruments that mature in a matter of days. So it is all extremely liquid, as close to ""Money"" as you can get without actually being money.  It is extremely rare for a money market fund to lose value, or ""break the buck."" During the crisis of 2008, only one or two funds broke the buck, and it didn't last long. They had gotten greedy and their short term investments were a little more aggressive as they were trying to get extra returns. In short, your money is safe in a money market fund, and your 401K plan should offer one as the ""cash"" option, or at least it should offer a short-term bond fund. If you feel strongly that your money should be in actual cash, you can always stop contributing to the 401K and put the money in the bank. This is not a good idea though. Unless you're close to retirement, you'll be much better off investing in a well diversified portfolio, even through the ups and downs of the market."

 <=SEP=> Your employer decides what options you have in the 401k. You can talk to your HR about that. There are requirements for diversity of various types of investments, money-market funds is being one of them. That is the investment account equivalent of cash. While it is not really cash but rather short term bonds - the term is generally very short and the risk is very limited. You can't earn much there, and you can't lose much there - so for all intents and purposes you can treat is as a cash-equivalent.

 <=SEP=> The short term bond fund, which you are pretty certain to have as an option, functions in this capacity.  Its return will be low, but positive, in all but the most dramatic of rising rate scenarios. I recall a year in the 90's when rates rose enough that the bond fund return was zero or very slightly negative. It's not likely that you'd have access to simple money market or cash option.

 <=SEP=> This situation, wanting desperately to have access to an investment vehicle in a 401K, but it not being available reminds me of two suggestions some make regarding retirement investing: This allows you the maximum flexibility in your retirement investing.  I have never, in almost 30 years of 401K investing, seen a pure cash investment, is was always something that was at its core very short term bonds. The exception is one company that once you had a few thousand in the 401K, you could transfer it to a brokerage account. I have no idea if there was a way to invest in a money market fund via the brokerage, but I guess it was possible. You may have to look and see if the company running the 401K has other investment options that your employer didn't select. Or you will have to see if other 401K custodians have these types of investments. Then push for changes next year. Regarding external IRA/Roth IRA: You can buy a CD with FDIC protection from funds in an IRA/Roth IRA. My credit union with NCUA protection currently has CDs and even bump up CDs, minimum balance is $500, and the periods are from 6 months to 3 years.

 <=SEP=> "There is no zero risk option! There is no safe parking zone for turbulent times! There is no such thing as a zero-risk investment.  You would do well to get this out of your head now.  Cash, though it will retain its principle over time, will always be subject to inflation risk (assuming a positive-inflation environment which, historically in the US anyway, has always been the case since the Great Depression). But I couldn't find a ""Pure Cash - No investment option"" - what I mean by this is an option where my money is kept idle without investing in any kind of financial instrument (stocks, bonds, other MFs, currencies, forex etc etc whatever).  Getting back to the real crux of your question, several other answers have already highlighted that you're looking for a money market fund.  These will likely be as close to cash as you will get in a retirement account for the reasons listed in @KentA's answer. Investing in short-term notes would also be another relatively low-risk alternative to a money market fund.  Again, this is low-risk, not no-risk. I wanted such kinda option because things may turn bad and I may want nothing invested in the stock markets/bond markets. I was thinking that if the market turns bear then I would move everything to cash Unless you have a the innate ability to perfectly time the market, you are better off keeping your investments where they are and riding out the bear market.  Cash does not generate dividends - most funds in a retirement account do.  Sure, you may have a paper loss of principle in a bear market, but this will go away once the market turns bull again.  Assuming you have a fairly long time before you retire, this should not concern you in the slightest. Again, I want to stress that market timing does not work.  Even the professionals, who get paid the big bucks to do this, on average, get it right as often as they get it wrong.  If you had this ability, you would not be asking financial questions on Stack Exchange, I can tell you that. I would recommend you read The Four Pillars of Investing, by William Bernstein.  He has a very no-nonsense approach to investing and retirement that would serve you (or anybody) well in turbulent financial markets.  His discussion on risk is especially applicable to your situation."

 <=SEP=> "Technically there could be a true cash fund, but the issue is it would need to have some sort of cost associated with it, which would mean it would have negative yield or would charge a fee.  In some cases, this might be preferable to having it invested in ""cash equivalents,"" which as you note are not cash.  It is important to note that there is nothing, even cash or physical precious metals, that is considered zero risk.  They all just have different risks associated with them, that may be an issue under certain circumstances.  In severe deflation, cash is king, and all non-cash asset classes and debt could go down in value.  Under severe inflation, cash can become worthless. One respondent mentioned an alternative of stopping contributing to a 401k and depositing money in a bank, but that is not the same as cash either.  In recent decades, people have been led to believe that depositing your money in the bank means you hold that in cash at the bank.  That is untrue.  They hold your deposit on their books and proceed to invest/loan that money, but those investments can turn sour in an economic and financial downturn.  The same financial professionals would then remind you that, while this is true, there is the Federal Deposit Insurance Corporation (FDIC) that will make you whole should the bank go under.  Unfortunately, if enough banks went under due to lack of reserves, the FDIC may be unable to make depositors whole for lack of reserves.  In fact, they were nearing this during the last financial crisis.  The sad thing is that the financial industry is bias against offering what you said, because they make money by using your money.  Fractional reserve banking.  You are essentially holding IOUs from your bank when you have money on deposit with them. Getting back to the original question; you could do some searching and see if there is an institution that would act as a cash depository for physical cash in your IRA.  There are IRA-approved ways of holding physical precious metals, which isn't all too different of a concept from holding physical cash. 401k plans are chosen by your company and often have very limited options available, meaning it'd be unlikely you could ever hold physical cash or physical precious metals in your 401k."

 <=SEP=> "My 401k allows cash holdings to 100% if desired. I'm not sure why some won't, they are making money on your money after all. If you are looking to the funds vehicles for investing suggestions however, they will never allow cash. I found you must go into ""Invest on my own"" vehicle to make that change.  I have beaten and timed this market several times by sitting with cash on the sidelines. The only time I missed it was when I talked to a fund administrator in 2008 dot com crash and stayed in at this suggestion. I told him I didn't see where the market could go much higher as I had made 12-28% on some funds. He was dead wrong of course and I lost 50% that year.  Now, trust me, in 2017, assets are grossly overvalued. If they won't let you deposit to cash, don't invest and just save your money until the next crash."
