Long Term Cycles Play A Major Role In Currency Movements
Right now the Dollar is and has been in a steady decline over the last 5 years but I'd bet that at some time over the next 5-10 years it will come back. Perhaps not as strong as it once was but far stronger nevertheless. Just normal foreign exchange cycles at work.
Sterling also enjoyed a good run of strength for several years (mid 1990s to 2000) but now, especially against the Euro, it is struggling. Soon after the Euro was introduced hardly anyone gave it a chance and many anti-euro sceptics were smirking at its sorry plight as it plunged to 0.80 against the dollar. But now it's around 1.60, an increase of 100%.
Of course though there are normally two sides to a currency story. This means it is possible for two currencies to be weak (or strong) but one is far weaker than the other, as we're now witnessing with Sterling against the Dollar around 2:1. However, if you look at sterling against many of the other currencies its form is generally poor.
Economic Policy Plays A Dominant Role But Doesn't Move Quickly
Ultimately currency movements are dictated by economic policy, either global or country specific. However the effects of economic policy are often not felt in the short-term. For example, tax cuts, increases in budget deficits/surpluses, rises/falls in unemployment have little if any effect on day-to-day movements but do carry significant weight over many months and years. And it's these dominant trends that are of interest to the long-term currency investor.
How To Invest In Currencies - Pick Your Spots
In my view the best way to invest in currencies is, unless you're a good reader and interpreter of macro economics, is to use long-term charts.
Many people don't like charts for various reasons. However I have found that if simply used, ie just look at the shape of the chart and past history, they can often be a good guide of when and when not to invest.
One of the areas which has worked well in the past with currencies is to pay special attention to extreme price levels and then start to ease into a currency if/when those levels are breached. The term 'easing in' means to initially buy or sell in small amounts and then add to that position if the market continues to go against you to build up an average priced position.
Look at the chart below, the dollar/yen cross rate. The market is now trading around 103 but there's a massive and seminal low at 79.80 from 1995.
That level is a long way off (23%) and I'm not suggesting that's where the cross is heading, but who knows what will happen over the next few years in the current economic climate?
