Two relatively quick items that I want to address today; they have been in my 'to do' box for a while.

Negative Rates

One of the most interesting features of the fixed-income landscape today, and one that will likely serve in the future as an exam question on finance quizzes, is the increasingly widespread proliferation of negative nominal interest rates among government bond markets...and occasionally even for high-quality corporate paper.

In finance theory, this can't happen. Because currency earns a 0% nominal interest rate, theory says that no rational person would ever accept a negative nominal interest rate. If I have $50 today, and put it in the bank, I will have $49 tomorrow. So why not just keep the $50 in my wallet? (Obviously this leads to high cash balances, which means low monetary velocity, by the way). And this is true in the absence of "other costs."

So why are so many interest rates negative? Are individuals irrational? No: at least not so irrational that they prefer less money to more money. However, what is true at an individual level does not necessarily scale to the institutional level. An institution, such as a money fund or corporation, does not have the freedom to hold its assets in physical currency. Microsoft has $90 billion in cash and equivalents. If this were in $100 bills, it would weigh about one thousand tons. That's a pretty big vault. And vaults cost money. Guards cost money. And, if Microsoft had this money in the vault, it would be harder to spend. It is much easier to wire $5 million than it is to send an armored car.

In the presence of those costs, Microsoft and other institutions will accept a negative interest rate. It will invest its money at a negative rate rather than build a vault.

Now, an important (if obvious) point is that cash balances are so high, and interest rates so low, because global central banks are making sure we have plenty of cash. Too much cash chasing too few investment opportunities causes rates to be low.

Walmart and Minimum Wage Increases

It has been a few weeks now, but when Walmart in February announced it was going to increase the minimum wages it plans to pay its employees (preceded by Starbucks, Aetna, and the Gap and followed by TJX and Target), I received a number of queries about what the hike was going to do to inflation. Is this the beginning of the much-feared "cost-push inflation"?

The answer is no. Wages, as I have said many times, follow inflation rather than lead it. Think about it: wouldn't it be really weird for companies to raise wages and then raise prices, to the extent that they have control - at least with respect to timing - over both? No, whatever price increase is going to be caused by the increase in the wages Walmart expects to pay is already in the price. Walmart is not surprised by their own move to raise wages. Nor is anyone surprised by the general increase in the minimum wage, which happened in 2009.

So, while I continue to believe that inflation is rising, and will continue to rise...I don't believe that the increase in prices is going to be any faster due to these wage increases. It does, however, increase my confidence that inflation is rising, since obviously these retailers are confident enough in the pricing environment to be able to increase wages (which are sticky - it is harder to lower them than to raise them).
