"It's a combination of global nervousness and risk-off with the tanker incidents in the Gulf of Oman," says Peter Cavanaugh, the senior client advisor at Bancorp Treasury Services.
"In the current environment, financial markets and currencies are vulnerable to bad news."
Explosions on two oil tankers in the Gulf ratcheted up tensions between the US and Iran with one blast damaging the hull of a Japanese-owned tanker and setting on fire a Norwegian-owned vessel.

China had imposed duties of 13-14.1 per cent on those products since 2014 on the grounds that they were being dumped on the Chinese market at below-market prices.
The move appears to be in retaliation to the US ratcheting up tariffs on about US$200 million of Chinese imports and threatening to impose tariffs on other products.
