Central banks have recently created a great deal of volatility in foreign exchange markets. The Fed reiterated its message on Wednesday that it will not raise interest rates anytime soon, which caused a big slump in the dollar. The euro, as a result, surged more than 4% to the dollar, the largest increase the euro has seen in about 15 years. The euro and dollar are the world’s most heavily exchanged currencies and as a result, many in the financial sector are curious to see what the future holds. Many are looking back to when the Swiss central bank abandoned its policy of fixing the franc to the euro. This trend has brought up additional concerns, mainly concerning the regulations brought in after the financial crisis that have hindered liquidity in markets by preventing banks from making risky bets. Volatility indexes are at their highest levels since around 2011. However, others see this as return to normalcy with higher levels of volatility. The dollar is currently experiencing its fastest pace ascent in 40 years, so there is currently risk for a pullback according to many.
