US TSYS: Tsys aided by FX-tied buying as the US dollar weakens vs. yen since

about 9am ET, which spurs black-box buying in Tsys, said traders. The black

boxes appeared to be at work overnight, which spurred confusing trading, as one

would have expected Tsys to gain a bid amid N.Korea missile firing, but instead,

black boxes sold Tsys as Japanese yen got hurt overnight. "Try trading Tsys

overnight," sighed one trader. "The algos are controlling things. Now, the yen

is getting stronger, dollar weaker, so they are buying Tsys."

- Now Tsys appear to hold a better tone as the market continues to work off the

supply overhang from this week's 3/10/30Y auctions, and as some traders

anticipate/do mild safe-haven buying into the weekend. N.Korea danger still

looms after overnight missile firing over Hokkaido, Japan, and within range of

US's Guam. UN Security Council meanwhile has a closed-door meeting this

afternoon on N.Korea.
