The Federal Reserve Bank have found a new partner in its struggle to confirm interest rate increase screens through the US economy. The foreign banks have partnered with the Fed to control interest rates.

The trend of Fed borrowing billions daily to set a base under its standard policy rate has been conquered by foreign monetary authorities, Bloomberg said. The money-market mutual funds in the US were anticipated to be the dominant players in this business. This change in trend, encouraged by instability in overseas exchange markets, is benefiting the Fed to sustain its objective for the federal funds ratio subsequent to its decision previous month to increase rates once seven years near zero.

The reverse repurchase deals are means to tie up the excess reserves of about $3 trillion in the banking system formed by Fed's after crisis bond programs. Bloomberg said that this excess reserves would weigh on interim borrowing costs if they are not pulled out.

Dealers polled before the Fed's rate increase announcement in Dec.16 showed the average respondent anticipated the US bank would have to borrow $300 billion on a day-to-day basis through the reverse repurchase program to maintain interest rates in the fresh 0.25% - 0.5% target range. But, the daily borrowings has averaged just around $153 billion as rate soar. On January 20, borrowing by overseas central banks puffed to $216 billion, which was more than twice the volume borrowed last year, Bloomberg said quoting a data published by Fed.

The reverse repurchase programs with oversea central banks increased $60 billion since July.

According to Forbes, the US Federal Reserve Bank decided out of an interest rate hike because of China in September and this might repeat in 2016, where Fed evidently planning on increasing interest rates four times.

MarketWatch quoted Robert Brusca, Chief economist at FAO Economics, as saying, "The Fed cannot control markets and now it has core prices in the 2% range for the CPI and still strong job growth. These are metrics to cause some at the Fed to stay the course."

MarketWatch said that the chaos in the share market, an uncertain forecast for the US economy and dropping oil prices have made the traders remain certain that the Fed will not be able to raise its interest rates again in the present year 

Crandall, a former Fed economist, told Bloomberg that the oversea central bank managers are using the reverse repurchase market as a liquidity pillow, for they are easier to liquidate than debt holdings in the US. The reverse repurchase program releases a downward pressure on the money-market rates in the US. This overseas demand makes it easier for Fed to hold its rate floor.
