This was a volatile week, but most of the volatility was to the upside.
Among the currencies, the EUR was strongest, rising 4% to close at 24.9 mg. The USD was second, up 2.7%, closely followed by BTC, which gained 2.4%. The laggard was the JPY, which still managed a respectable 1.8% gain. More comments on the USD later in this post.
