Ideally, a rise in the price of oil, resulting from improvement in worldwide economic conditions, would increase inflation expectations and also pull up long-term interest rates. This could steepen the yield curve, or at least displace it upwards. All other things being equal, bank shares would benefit and their poor performance of the last few weeks would turn around. Even though higher interest rates would penalize a certain number of sensitive sectors, the breath of fresh air for the banking sector would restore some appetite for risk which has recently been lacking.
More realistically, i.e. with an economy well into the expansion phase, there is little chance this series of events would last. It is not even sure they would have the time to develop in the first place, despite some indications to the contrary over the past few days.
Trends in the financial markets have accelerated in the last few days. After hesitating slightly at the start of 2018, it is increasingly obvious to investors that reflation is around the corner. That belief is based on widespread growth, a surging oil price, the first positive effects of Donald Trump’s tax reform – with giant US companies promising to repatriate profits – and good news on investment and jobs. It is hard to see how that situation could fail to end the phase of latent deflation in the last few years and support expectations – seen throughout 2017 – of inflation getting back to normal. The impact of rising oil prices alone could significantly change the inflation situation, judging by how sensitive inflation is to movements in oil prices. If crude stabilises at $70 per barrel between now and the summer, inflation could rise by more than half a point in the industrialised world, taking it well above the 2% target that it touched only briefly in February 2017.
So what could prevent a significant increase in interest rates? It is very tempting to change our outlook for 2018. How is the interest-rate environment likely to develop?
Disinflation continues to gain ground around the planet and things don’t seem poised to improve anytime soon. The effects of the drop in global oil and agricultural commodities in the coming months will compound the consequences of sluggish growth amid persistent competitive tension. Global inflation could fall to around 2.5 % to Q1 2015 while a growing number of economies slip into negative inflation territory. Such an environment could very well lead to a new slump in global interest rates…
