Will markets feel so brave without central bank protection?

Perhaps one of the more surprising aspects of markets in recent weeks has been the extent to which they have remained resilient in the face of what might be termed extreme provocation. Admittedly there was something of a wobble around the time President Trump decided to end US participation in the Iran nuclear deal, but on the whole they have remained remarkably quiet. Add in the prospect of unrest on Israel’s borders and the ongoing situation in North Korea, and it is clear that there are plenty of geopolitical threats to worry about (not to mention the very fact that Donald Trump occupies 1600 Pennsylvania Avenue).

Not so many years ago, these were the kinds of issues that would have investors running for cover. But equity option volatility continues to ease back and is well below the levels achieved in early February which is a sign of reduced tension. Indeed, the FTSE100 yesterday hit an all-time high, although this was primarily the result of a weaker pound that boosts the sterling value of foreign currency earnings in a market which generates 70% of its revenue abroad. Nonetheless, it does raise a question of why markets can continue to remain steady in the face of numerous headwinds.

One reason is that central banks in Europe and Japan continue to provide huge amounts of liquidity. In European bond markets, the central bank remains a huge buyer and it is almost impossible to get hold of certain bonds – particularly corporate securities – due to the ECB’s actions. Against this backdrop there is little reason for markets to panic in the face of events that may – or may not – cause prices to fall. This is entirely rational behaviour. If investors believe there may be a small dip in prices that will subsequently be reversed as the central bank backstop kicks in, it makes sense to hold onto positions and thus save the trading costs associated with closing them and reopening them again. In other words, markets can be afford to be brave in the face of these threats. But how long might such behaviour persist?

In the US, the Fed has raised rates six times since December 2015, by a total of 150 bps, and it is winding down its balance sheet, so the degree of support which it once provided is being slowly eroded. We are starting to see bond yields creep up with many investors concerned by the fact that the US 10-year yield has hit a new multiyear high, returning to a level not seen since 2011 (3.128%). It is hard to say why rates have edged up so quickly of late but then it was equally difficult to explain why the long end of the curve did not respond as monetary policy was tightened. They are probably now where they should be. In the process, the differential with German Bunds has widened out to around 260 bps – a spread last seen in the late-1980s. So long as the ECB is still engaged in buying Emu bonds, there is little prospect of a substantial narrowing. But before too long – perhaps once the ECB buying programme ends – European yields will also begin to rise. Indeed, Italian yields are already edging up as political concerns mount regarding the formation of a new coalition government.

It currently feels as though we are in the midst of a phoney war as markets digest the implications of Fed tightening. They don’t want to sell because a strategy of shorting the market has not paid off over the past nine years. But as the Fed increasingly normalises monetary policy and the ECB contemplates an end to its QE programme, the special conditions which have supported valuations, and prompted a divergence in asset prices from fundamentals, may well force investors to take a closer interest in some of the global threats which are bubbling up. And they may not like what they see.
