FX comment: Scramble for dollar liquidity intensifies

It was an old friend, still trading forward cable, who first alerted me to the beginnings of a Libor/OIS basis blowout a couple of weeks ago. But at the start of this week the move took a more desperate turn as the hunt for dollars accelerated with rumours of a Spanish bank being unable to cover its short-term USD funding.

Over the past two weeks, one-month and three-month GBP/USD FX swaps have moved from –2 and –5 to +2 and +5 respectively, equating, by my reckoning, to about 35 basis points of dollar tightening in the interest rate spread. But it took a note on Tuesday from Laurence Mutkin and Elaine Lin of Morgan Stanley to put the move in some perspective.

They point out that that the ECB’s “full-allocation USD tenders provide an unlimited amount of USD to banks at an implied OIS+100bp”.
