Negative rates are about to smash Swedish bank profits

Last month Sweden’s Riksbank, the country’s central bank, took a step into the unknown by lowering its key interest rate into negative territory in an effort to combat falling inflation. However, the experiment is starting to pose serious problems for Sweden’s high-street banks.

In simple terms, retail banks make their profits by charging higher interest rates on the money they lend than they pay on the money they take in from savers or other banks. In a traditional model, a bank is simply an intermediary channelling money that people wish to put away for a rainy day to those who need to spend money now in order to finance an investment or a house etc.

But when you get negative interest rates things all start going a little haywire.

Here’s the problem. When a central bank introduces negative interest rates it effectively charges banks to hold money there. The idea is that charging institutions for holding cash will mean that they are more willing to spend the money now rather than pay a charge for storing it. This, in turn, will help boost inflation with Sweden’s consumer prices having fallen 0.2% in January compared to a year earlier following a 0.3% drop in December.

The chart below shows Swedish inflation (purple line) versus the Riksbank’s key interest rate:

So what does this mean for banks? Well initially lower rates offer a boost to the banks as they help to lower funding costs by pushing down the rates they are charged by other banks and depositors to lend them money (as long as it’s higher than the -0.1% the Riksbank is charging they are still better off).

Lower funding costs mean that the difference between the rate that they are charging on loans they provide to customers and the rate they are having to pay out rises, which equals higher profits.

This is exactly what we have seen in Sweden:

This process should also be good for borrowers. In a competitive market, lower funding costs should start to pull down interest rates on new loans as banks find that they can gain market share against their competitors by lowering rates. That is, people can borrow more cheaply than they could previously — again helping to boost spending in the economy.

However, once interest rates dip below zero these benefits grind to a halt. Unfortunately, while governments appear to be able to borrow at negative nominal rates, individual banks are highly unlikely to be afforded the same luxury. This is in part because savers can simply shift their money out of the banks if they start trying to pass the charge onto their customers while other banks may start worrying about the stability of their own funding and reduce lending to other institutions.

In other words the zero lower bound — whereby rates get stuck at zero and can fall no further even if inflation remains low — remains a big problem even though central banks are increasingly pushing through it. If banks can’t lower their cost of funding, it means they will either see lower profits or even be forced to raise the interest rates on their loans in order to make up for the losses being imposed by the central bank.

This is already happening in the German network of regional savings banks, or Sparkassen, which are heavily reliant on customer deposits and are struggling to eek out a profit.

That we haven’t seen these problems emerge yet in Sweden is owed predominantly to the impact of new banking regulation forcing banks to increase their capital buffers (the amount of high-quality capital they have to hold to protect against possible shocks). As Moody’s ratings agency writes (emphasis added):

According to Sweden’s banking regulator Finansinspectionen, in recent years banks have been able to
extract higher lending margins, even as repo rates started falling in 2011, by not fully reflecting the reduction
in their funding costs in the lending rates they offer, as shown below. The costs of covered bond funding (which backed 77% of mortgages at year-end 2014) have declined, even as deposit pricing nears its floor. To date, competitive pressure has eased as all major banks have required higher margins to build buffers to
comply with higher capital requirements that were introduced in August 2014, and to meet their double-digit
return on equity targets with these larger capital bases.

This is all about to change, according to Moody’s. Smaller lenders have expressed their intention to start increasing their mortgage lending — a move that will challenge larger banks to lower their lending costs in order to maintain market share. And even if they don’t, the temptation for larger players to take some of their competitors’ business will eventually become overwhelming.

What this implies is that a squeeze on profits in the Swedish banking sector is now imminent.
