It has been recently pointed out that the polarization BICEP2 results areconsistent with the identification of an inflaton mass m \simeq 10^{13} GeVwith the SUSY breaking scale in an MSSM with a fine-tuned SM Higgs. Thisidentification leads to a Higgs mass m_h \simeq 126 GeV, consistent with LHCmeasurements. Here we propose that this naturally suggests to identify theinflaton with the heavy MSSM Higgs system. The fact that the extrapolated Higgscoupling lambda_{SM}\simeq 0 at scales below the Planck scale suggests theHiggs degrees of freedom could be associated to a Wilson line or D-braneposition modulus in string theory. The Higgs system then has a shift symmetryand an N=2 structure which guarantees that its potential has an approximatequadratic chaotic inflation form. These moduli in string compactifications,being compact, allow for a trans-Planckian inflaton field range analogous to aversion of monodromy inflation.
