In the past two quarters, the bank has bought around 80 billion euros worth of debt each month. It provided no numerical guidance for the three months ahead, but analysts had predicted prior to the meeting that purchases would fall to between 60 billion and 70 billion euros in those months. “The ECB is delivering mainly as expected today,” analysts at TD Securities said in a report on Thursday. “Looking ahead, the focus will be on how the ECB defines "moderately" - anything less than €60bn/mo could be bearish.” The euro was last up 0.02% on the day at $1.1816, though trading was volatile after the ECB statement with the single currency bouncing between $1.1809 and $1.1842. The ECB trod cautiously and flagged no other moves, notably how it ultimately plans to dismantle the 1.85-trillion-euro Pandemic Emergency Purchase Program (PEPP). Investors are also focused on when the U.S. Federal Reserve is likely to begin paring bond purchases, though a move is unlikely to be announced until at least later in the year after a weaker than expected jobs report on Friday. The August slowdown in job growth will not throw off the Fed"s plans to reduce its asset purchases this year, four Fed officials said on Wednesday, though some cautioned a final decision requires more data. Data on Thursday showed that the number of Americans filing new claims for jobless benefits fell last week to the lowest level in nearly 18 months, offering more evidence that job growth was being hindered by labor shortages rather than cooling demand for workers. The dollar index was last down 0.14% at 92.53. The index has recovered from one-month lows of 91.94 reached on Friday as Treasury yields rise. Cryptocurrencies edged higher after large and sudden price drops on Tuesday. Bitcoin gained 1.87% to $46,950 and ether rose 0.76% to $3,519. ======================================================== Currency bid prices at 9:51AM (1351 GMT) Description RIC Last U.S. Close Pct Change YTD Pct High Bid Low Bid Previous Change Session Dollar index 92.5520 92.7030 -0.15% 2.857% +92.7620 +92.4610 Euro/Dollar $1.1816 $1.1816 +0.02% -3.28% +$1.1842 +$1.1809 Dollar/Yen 109.8200 110.2100 -0.34% +6.33% +110.2650 +109.8050 Euro/Yen 129.76 130.28 -0.40% +2.24% +130.3200 +129.7300 Dollar/Swiss 0.9185 0.9220 -0.36% +3.83% +0.9223 +0.9167 Sterling/Dollar $1.3843 $1.3771 +0.53% +1.33% +$1.3850 +$1.3755 Dollar/Canadian 1.2661 1.2694 -0.26% -0.57% +1.2727 +1.2659 Aussie/Dollar $0.7389 $0.7365 +0.33% -3.94% +$0.7394 +$0.7347 Euro/Swiss 1.0854 1.0893 -0.36% +0.43% +1.0897 +1.0852 Euro/Sterling 0.8535 0.8579 -0.51% -4.50% +0.8588 +0.8533 NZ $0.7129 $0.7102 +0.41% -0.70% +$0.7133 +$0.7084 Dollar/Dollar Dollar/Norway 8.6705 8.7130 -0.36% +1.11% +8.7245 +8.6680 Euro/Norway 10.2455 10.2925 -0.46% -2.12% +10.3135 +10.2457 Dollar/Sweden 8.6195 8.6273 -0.15% +5.16% +8.6435 +8.6020 Euro/Sweden 10.1845 10.1994 -0.15% +1.07% +10.2135 +10.1810 (Editing by Philippa Fletcher)
