‘Tis the season for predictions of the New Year.

Before that, two surprises in today’s markets: our overnight droning of Qassim Suleimani, and this morning’s drop in the December Institute of Supply Management manufacturing index to 47.2, a ten-year low, below 50 a contraction. From paired events like this we learn relative importance: after the U.S. strike markets opened in fearful trades but were improving when the ISM report knocked bond yields back down. Economic weakness matters more than Middle East counter-counter-counter terror: the U.S. 10-year T-note at 1.80 percent reached a one-month low, mortgages back under 4.00 percent.

On to 2020. Perhaps the best all-time U.S. business thinker, who invented the study of management: Peter Drucker (1909-2005). His advice about the future: “Nobody can predict the future; the idea is a firm grasp of the present.”

A few of his other observations: “There is nothing so useless as doing efficiently that which should not be done at all... The purpose of a business is to create a customer... So much of what we call management consists in making it difficult for people to work."

2020, “The Year of the Accident.” One year ago, markets and the economy had strong momentum: the Fed would either reverse rhetoric and rates, or we would have a recession. Nothing in today’s markets or economy is so poised.

Resist misinformation in markets, not so much outright fabrication as exaggeration by hysterical headline, or by publication at all. The easy targets in each of us: first (always) our fears, then our hopes. So, the following will evaluate 2020 by estimating relative risks ahead, from least to largest:

Housing has the least risk of any market. Housing is vulnerable to overbuilding, credit excess, and recession; we have none of the first two, and recession risk is low. Of course the risk to value in an individual home is local, governed by these three elements: population migration to or away, supply scarcity, and local economy.

Geopolitical risks. Despite events overnight, conflicts make good entertainment but in this world only temporary market upsets. There are bad guys, but nukes have made large-scale war pointless, and besides, war is bad for business. We have worried about war in the Middle East interrupting oil supplies ever since the first and last time it did, in 1973. Enough. On grand scale, the U.S. must reduce its global power presence because we can’t afford so much presence. No military operation is more difficult than redeployment under fire. Mr. Obama tried passivity, and Mr. Trump has tried power without and in contempt of allies. Short, sharp, and limited counterstrokes with allies is the idea, last night at least half right.

Currencies. Every day somebody yells about the dollar too strong or weak, or the same for somebody else’s money. Give it up. Currencies are effect, rarely cause. Changes in relative value mediate different levels of productivity among nations. Brexit is a subset of currencies, locally important, not globally.

The stock market matters, of course. At the moment, stocks running up are a benefit to housing; if not a direct flow from one market to the other (except among the IPO- and option-wealthy), vast growth in retirement accounts embolden purchase of more expensive homes. If stocks crater, of course it will hurt the economy and housing, but if anyone could truly forecast stocks we’d all know by now.

Climate. Be concerned and study. As a near-term economic hazard, nearly undetectable. A serious long-term hazard, but until we have technological means to decarbonize without ruining the world’s economies we are not going to make more progress than we are. Better not to distract ourselves by worrying about the uncontrollable.

Debt. This longest of all U.S. economic recoveries is distinguished by the near-total absence of a credit cycle for the first time in modern history. Re-regulation and strong memory in markets have prevented easier credit and unwise expansion, except in corporate credit. A corporate contraction could have unpleasant feedback into stocks via diminished buybacks. In the long run debt will matter, and will bring some discomfort, but 2020 is not the long run.

Trade. Nothing is more important to the global economy than trade. The White house-based trade war is likely to quiet down if only because suicide is unwise in an election year. But there are other risks to trade: China and Germany are outright predators, blind to their own circular risks from misbehavior.

The Fed. Every signal from the Fed -- smoke, wig-wag, jawbone, today’s minutes of the December meeting -- says that it is content with current policy, has no tilt to higher or lower rates in 2020 or possibly ever. Drucker again: “The only thing we know about the future is that it will be different.” Perhaps the biggest question in 2020: what and when will alter the Fed’s outlook and in which direction?

Demography. Thus far dodging any particular prediction, here we go: the tilt in interest rates is down, in the U.S. and everywhere. Aside from the various risks above, the deep driver is the aging of populations in all of the developed world, and outright shrinkage in more places. Japan’s population crested ten years ago at 128.1 million, now 126.3 million -- and shrank in last year alone by one-half million.

The aged are not particularly productive, and do not consume much except for the resources of the young. One consequence: every nation and its central bank is attempting to push growth faster than possible. In most of modern times such stimulus would produce inflation, and it may, but for the last twenty, maybe thirty years the world has been in a Keynesian “liquidity trap,” central banks pushing on overdone spaghetti. We are likely to stay trapped, and not bad for housing -- unless you’re in one of those places losing people.

Oh, the election? Remember, 2020 will be the Year of the Accident.

Study this chart! This is the 10-year T-note in the last twenty hours. The black horizontal line at 1.875 percent was yesterday’s New York closing yield. Pre-market trading last night, 2:00AM EST opened down to 1.84 percent, and kept going to 1.80 percent by 6:40AM. When the market actually opened, fear had abated, the yield rising. The ISM report arrived at 10:00AM and economic fear took over. At the tail end another try at recovery stopped cold upon release of the Fed’s December minutes at 2:00. And all begins again next week, responding to a mountain of brand-new data.
